GEORGE MCGOVERN, OF RICHMOND, VIRGINIA.

COTTON-PRESS.

SPECIFICATION forming part of Letters Patent No. 328,798, dated October 20, 1885. Application filed September 5, 1.885. Serial No. 176,252. (No model.)

.To all whom it may concern.-

Be it known that I, GEORGE McGovERN, a citizen of the United States, residing at Richmond, in the county of Henrico and State of Virginia, have invented certain new and useful Improvements in Ootton-Compresses; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which 1t appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specication.

y My invention has relation to certain new and useful improvements in cotton compresses; and the object of the invention is to provide a means for simply and cheaply compressing bales of cotton, to facilitate their transportation from the planter to the factory; and the novelty consists in the construction of the same, as will be hereinafter more fully described.

In the accompanying drawings the same letters of reference indicate the same parts of the invention.

Figure lis a perspective view of my cotton-compress. Fig. 2 is a front elevation, partly in section, and Fig. 3 is an end elevation of the same.

A is the bed-plate, and rigidly secured to it are four columns or stanchions, B B B B,

which support the middle cross-head, C, and

the auxiliary head D, the former head, O, being secured to said stanchions by nuts'c and the latter head, D, by nuts d.

E is a central brace cast integral with the head D, and extending downward to support the upward strain on the central part of the lower head, C.

F is the follower, provided with corner guide-brackets, e, which insures a true vercl motion thereof on the stanchions B B GGare two screws, rigidly secured by their lianges g g to the follower, so as to move with it. These screws pass upwardlythrough two screw-worm nuts, H H, and freely through suitable openings in the upper head, D,which act as guides for the upper end of the said screws. One of the screws,G,is provided with a right-hand thread, and the other one, G', a left-hand thread, and the threads in the wormnuts correspond to the threads on their respective screws. These worm-nuts are provided with threads I I on their periphery, which mesh with each other at K, and also respectively mesh with the worms L L on the shaft M, which is provided with a pulley, N, located at either or both ends of said shaft, the worm L being a righthand screw to correspond with the thread on the worm-nut H, and the worm L being a left-hand one to cor respond with the thread on the other wormnut,H. From this it will be clcarlyseen that as the shaft M is rotated the worm-nuts H H will be simultaneously operated, and theyin turn operate the screws G G up or down, according tothe direction of rotation of the said shaft.

A very important feature of this movement is the meshing of the teeth of the worm-nuts H Hf with each other, as by this arrangement the end-thrust of the shaft M is entirely done away with, and what would otherwise be an immense loss of power is taken up and utilized by the meshing of said worm-nuts. These worm-nuts H H are secured in place, so as to revolve freely in the middle cross-head, C, by means of collars h h; and O is a circular beveled steel rail set in a recess in the upper side of each of the worm-nuts, and a similar rail, O, is secured in a similar recess in the under side of the cross-head O, while between these rails is a series of conical steel antifriction rollers, P, which take up the pressure of the worm-nuts while the screws are being forced downward to compress a bale.

l. In a cotton-compress, a pair of wormnuts provided with teeth on their periphery, which mesh with each other and with worms on a common shaft, in combination with a pair of compression-screws operated by said shaft and worm-nuts, as set forth.

2. The combination, with a right and a left hand screw, of a pair of correspondinglythreaded worm nuts, the teeth on the periphery of one meshing with the teeth on the periphery of the other, and means for simul- Intstmony whereof I affix my signature in 1 lpyesenoefof two witnesses.

GEORGE MCGOVERN.
