What I claim as new and original, and desire to secure by letters patent, is applying to the hour socket of a clock, or register, made as above described, for the purpose of counting off, as the hours go round the stops upon the strike-wheel, or to stops arranged upon the strike-wheel shaft.

I also claim the application of two arms from a centre shaft, essentially as above described; the end of one of which strikes upon a register as above described, guiding the end of the other to stops upon the strikewheel, or to stops arranged upon the strike-wheel shaft.

I also claim the new mode of stopping the striking parts of a clock by means of pins or stops arranged upon the strike-wheel shaft, essentially as above described.

I also claim the combination in a clock of the lifting part—the stops arranged as above described. The two arms form a centre for the objects above described, and the register made and applied as above described— all together, or any two together.

Having thus described the nature of our invention, and the best means we are acquainted with for performing the same, we do not confine our. selves to the means above described so long as the stannate or stannite of soda, or of potash, be produced in a dry state, or in crystals, or in the state of paste, so as to pack in a small compass for ready and convenient transport. And we would wish it to be understood that what we claim is the manufacture of stannate and stannite of soda, and potash, by flux

ing nitrate of soda, or potash and tin.

\ . What I claim, therefore, as my invention, and desire to secure by letters patent, is the method, substantially as herein described, of closing the valve of a hydrant or stop-cock, by a spring or its equivalent, against the flow or pressure of the water or other liquid, whereby I am enabled to prevent any injurious result from the water ram, as described. And I also claim making the waste hole of the hydrant oblique, in combination with the shifting stopper, substantially as herein described, whereby the flow of water is prevented, or nearly so, whilst the valve is opened and the water within the body of the hydrant retained or discharged, when the

main valve is closed, as described. - l F. H. BARTHOLOMEW.

Although I have described the tubular bean, and claim the right to use such in a bridge, it will be evident that other arrangements or constructions of beams may be used ; and therefore I do not confine myself strictly to the proportions of the various parts, as expressed in the drawings, nor to the material or materials, as above set forth; but intend to vary such as circumstances may require, while I maintain an analogous combi. nation or combinations of them.

I do not therefore claim as my invention the combination of diagonal thrust braces and counter-braces, (which act by thrusts,) and vertical suspension rods; but that which I do claim as my improvement thereon consists in a combination of devices by which the diagonal braces operate either by thrust or tension, at pleasure, while the vertical rods at the same time operate either by tension or thrust; the said combination by which this peculiarity is derived being composed of the attachments of the diagonal braces and counter-braces, and upper and lower stringers, together with the double sets of nuts upon the vertical rods, one set being above and the other being below each stringer; the whole being substantially as herein before specified.
