It thus appears that while the structure disclosed in Sinclair's specification is confined to “ separate circular landings” for each water-tube, whereby the tube may be withdrawn from either side of the landing, the Engel specification does not contemplate a structure of this kind, nor can the tubes of his device be withdrawn from “either side” of a landing in the manner disclosed and claimed by Sinclair. There is no suggestion in the Sinclair specification that his invention covers anything broader than that specifically described therein, and which is carefully distinguished from the prior art of record. Construing, therefore, the claims in the light of Sinclair's specification, in which they originated, I am unable to agree with the Examiners-in-Chief that the subject matter of claim 1 is comprised in Engel's disclosure.

Count 2 is more limited than count 1 in that it is restricted to “ circular tube-landings,” which manifestly are not present in the Engel structure. Inasmuch as the patentee limits himself to this particular construction, it should not be held that such limitation is immaterial, as suggested by the Primary Examiner in his decision upon the motion for dissolution above quoted.

The decision of the Examiners-in-Chief is reversed as to count 1 and is affirmed as to count 2.

PATENTABILITY-REARRANGEMENT OF MACHINE.

The substitution of electrical means for operating a chuck-jaw in place of mechanical means shown in the art Held to require such rearrangement

of the machine as to involve invention. APPEAL from Examiners-in-Chief.

CHUCK.

Messrs. Dodge & Sons for the appellant.

BILLINGS, First Assistant Commissioner:

This is an appeal from the decision of the Examiners-in-Chief affirming the rejection by the Primary Examiner of claims 1, 3, 9, 10, 15, and 17, which are as follows:

1. In a chuck, the combination of a body, a relatively fixed jaw or jaws, a relatively free jaw, and an electromagnet carried by the body, adapted to move the free Jaw and to hold it in its working position.

3. In a chuck, the combination of a body portion, a jaw, means for securing mechanical adjustment of said Jaw, a second jaw, and an electromagnet work.

ing in conjunction with said second jaw to move the same toward the opposite jaw and to maintain it in such position, substantially as described.

9. In a chuck, the combination of a body portion, a slide or carriage mounted and movable in ways formed therein, a jaw mounted on the carriage, means for securing adjustment of the jaw relatively to the carriage, an electromagnet carried by the body portion, a lever fulcrumed upon the body portion adjacent to the carriage and having its short arm in operative relation with said carriage, an armature secured to the long arm of the lever, said armature standing in line with the electromagnet, and means for passing current to the colls of said magnet.

10. In a chuck, the combination of a body portion, a slide or carriage mounted and movable in ways formed in the body portion, a Jaw mounted upon the carrlage, means for securing adjustment of the jaw relatively to the carriage, an elbow-lever fulcrumed upon the body portion and provided with a short arm adapted and arranged to engage the carriage, and with an upwardly-extending U-shaped long arm, the upper ends of the opposite members of the long arm being formed with seats or sockets, an armature, arms secured to the ends of said armature, tap-screws extending outwardly from the ends of said arms into the seats or sockets formed in the ends of the U-shaped arm, and an electromagnet secured in the body portion of the chuck in line with the armature, substantially as described.

15. In a chuck, the combination of a hollow body portion, a slide or carriage mounted in ways formed in the body portion, a jaw mounted upon the carriage, means for securing adjustment of the jaw relatively to the carriage, an elbowlever fulcrumed upon the body portion, the lower short arm of said lever being in engagement with the slide or carriage, an armature connected to the upper U-shaped end of the long arm of said lever, a back plate secured to the body portion, spring-pressed plungers mounted in said back plate and bearing upon the U-shaped arm of the lever, an electromagnet mounted in sald back plate, and a driving-gear secured to the back plate and overlying the electromagnet.

17. In a chuck, the combination of a body, work-clamping means carried thereby, and electromagnetic mechanism for actuating said means.

The references are as follows: Wescott, February 25, 1873, No. 136,349; Finney and Campbell, September 26, 1882, No. 265,050; Dreses and Barker, September 17, 1895, No. 546,311.

Claims 1, 9, 10, 15, and 17 have been refused because of anticipation. Claim 3 was refused because it was held that it did not differ patentably from allowed claim 2.

The invention is a lathe-chuck, especially adapted for use in a turret-lathe. The chuck is provided with means for mechanically adjusting the jaws with reference to each other, the final grasping or clamping action being secured by the use of one or more electromagnets. The invention, except for the electrical connections, is of the type disclosed in the patent to Dreses and Barker. In this patent mechanical means are provided for actuating the jaw in order to accomplish the final grasping or clamping action.

The question to be determined, therefore, is whether the invention claimed by the appellant covers something more than the mere substitution of electrically-operated means for the mechanically-operated means shown in this patent.

In the patent to Finney and Campbell is shown an improvement in electric-arc lamps. In this patent the holder for one of the carbons is held in place by an electrically-operated clamp so constructed as to secure the holding-rod in any desired position. Broadly speaking, the securing means shown in the patent to Finney and Campbell might be called a “chuck.” It is provided with what may be termed a “relatively fixed jaw" and a “relatively free jaw," which together comprise the clamping means. Electromagnetic mechanism is provided for actuating the free jaw, so as to release the holder or secure it in position against the fixed jaw at will.

It is believed, however, that the appellant has done something more than merely to substitute an electrically-operated clamp for the mechanically-operated clamp shown in the patent to Dreses and Barker. The electromagnet must be arranged in conjunction with the relatively free jaw so that both may be carried by the body of the chuck, which body must be free to turn rapidly in performing the work for which the chuck is designed. In my opinion these substitutions cannot be made and a structure produced such as is covered in claims 1, 9, 10, and .15 without rearranging the machine so as to require the exercise of the inventive faculty.

Claim 17, however, does not bring out these differences in structure with sufficient definiteness to warrant its allowance. This claim might almost be said to be met in the patent to Finney and Campbell, considered alone. There is certainly not enough mechanism set forth in claim 17 to justify its allowance over the patent to Dreses and Barker when considered in connection with the patent to Finney and Campbell

As to claim 3, I agree with the Examiners-in-Chief that it differs in scope from claim 2. While the multiplication of claims is not to be encouraged, it is believed that these two claims are not so obviously alike as to justify the rejection of one upon the other.

The decision of the Examiners-in-Chief is reversed as to claims 1, 3, 9, 10, and 15 and affirmed as to claim 17.

EX PARTE WHITE AND MEDFORD.

Decided July 29, 1909.

147 O. G., 771. 1. PATENTABILITY-SUBSTITUTION OF EQUIVALENTS.

Where the art shows it is old to drive a lathe-spindle through gearing by an electric motor mounted on the head-stock and also that it is old to mount motor-armatures directly on the spindles of machine-tools, Held

unpa tentable to use the armature-shaft as the head-stock spindle of a lathe. 2. SAME-MOUNTING HAND-WHEEL IN CONVENIENT PLACE.

Mounting a hand-wheel in a convenient place on the spindle of a selfcontained electric-motor head-stock, Held to require no invention over the art, which showed such a wheel on a belt-driven head-stock.

APPEAL.

LATHE HEAD-STOCK.

Mr. George R. Hamlin for the applicant. BILLINGS, First Assistant Commissioner:

This is an appeal from the decision of the Examiners-in-Chief sustaining the Examiner's rejection of the following six claims:

1. A self-contained electric-motor head-stock for lathes, comprising an electric motor mounted on the lathe-bed, and a lathe-spindle, the rotatable element of the motor being carried by the lathe-spindle.

2. A self-contained electric-motor head-stock for lathes, comprising a fieldmagnet mounted directly on the lathe-bed, a lathe-spindle, and a motor-armature carried by the lathe-spindle.

7. A self-contained electric-motor head-stock for lathes comprising a variablespeed electric motor mounted on the lathe-bed, a lathe-spindle, the rotatable element of the motor being carried by the lathe-spindle, and means for regulating the speeds of the variable-speed motor.

8. The combination with a lathe-bed, of a self-contained electric-motor head. stock comprising a field-magnet detachably secured to said bed, a lathe-spindle, and a motor-armature carried by the lathe-spindle.

10. A self-contained electric-motor head-stock for lathes, comprising an electric motor mounted on the lathe-bed, a lathe-spindle carrying the rotatable element of the motor, and a band-wheel carried by said spindle.

11. In a motor-driven lathe head-stock, the combination with the motor, and shaft thereof for driving the lathe-spindle, of a hand-wheel for manually controlling the motor-shaft.

Of the references of record those pertaining especially to these claims are: Harper et al., October 11, 1898, No. 612,240; Duncan, May 7, 1901, No. 673,709; Hisey, November 4, 1902, No. 712,537; Benton, May 8, 1906, No. 819,842; German patent to Frank, December 2, 1905, No. 165,847; The Ironmonger, December 17, 1887, page 488.

The construction involved is a simple one and appears readily from an inspection of the claims. In claims 1, 2, 7, and 8 the point of the alleged invention is that the lathe-spindle itself—i. e., the member which drives the work—is also the shaft carrying the motorarmature. In Duncan is shown an electric motor mounted directly on the head-stock and driving a lathe-spindle through interposed gearing instead of directly, as above described. Benton and Hisey show two different forms of machine-tools whose rotating spindles are carried directly by the shaft of the electric motor, and while these are not lathe-spindles it seems clear that the essential idea of the alleged invention is disclosed by them and that to mount the lathe-spindle of Duncan directly on the motor-shaft instead of driving it through gears to give a wider range of speed requires merely the exercise of choice between two known ways in use in the same or analogous arts. Claim 7 includes an element not in claims 1, 2, and 8—that is, “means for regulating the speeds of the variablespeed motor.” It is contended on behalf of applicants that the rheostat shown by Duncan does not meet this feature because it is “ an ordinary rheostat and not a variable-speed rheostat.” In this applicants are in error, for Duncan clearly describes the function of his rheostat in the following language on page 1, lines 85 to 93:

The motor is provided with a controller, by means of which it may be run at various speeds, and hence it will be seen that a great variation in speed control is obtained. This controller may be of any desired construction and is preferably arranged so that there is a controllable resistance in circuit with the field and with the armature. I have shown this controller diagrammatically in Fig. 4.

Applicants put some emphasis upon the fact that their invention relates particularly to wood-turning lathes and is especially for the use of students in manual-training schools. This, however, cannot be considered to put the invention in an art different from the references or render claims patentable which otherwise fail to distinguish over the prior art.

Claims 10 and 11 cover the use of a hand-wheel on a head-stock of the kind above considered for the purpose of enabling the operator to turn the spindle by hand when desired and to afford a means of stopping the spindle quickly. The Ironmonger shows a hand-wheel for this purpose, and, though it is there applied to a head-stock driven by a belt instead of by an electric motor, the general manner of applying and using it is the same in the two cases. The best that can be said for applicant's use of the wheel is that the need of it is more obvious and imperative in his case than in the references, because without it there is nothing whatever by which to grasp the spindle. Merely to apply an old handle in a convenient place and for an old use, where some handle is an obvious necessity, cannot be said to require invention.

It must be held, therefore, that all of the claims define merely variations of ideas disclosed in the references which would be obvious to any one skilled in the art.

The decision of the Examiners-in-Chief is affirmed.
