Description
UNITED STATES RICHARD ESMOND, OF NEW YORK, N. Y., ASSIGNOR TO UNITED POWER- PRESS COMPANY.
IMPROVEMENT IN PREssEs.
Specification forming part of Letters Patent No. 142,220, dated August 26, 1873; application filed August 8, 1873.
Figure 1 represents a sectional front view of this invention. Fig. 2 is a horizontal section of the same.
Similar letters indicate corresponding parts. This invention consists in the arrangement of friction-disks and stops on the right-andleft-hand screw, which acts by means of nuts and toggle-levers on the follower of 'a press,
said friction-disks being provided with projections, and made .to act either in connection with the standard rising from the follower, or with the uprights which connect the headblock and the foot-block of the press, in such a manner that, by said friction disks and stops, the screwspindle is effectually prevented from being displaced, either in the direction of its axis, or in a direction transversely to said axis, and by these means the operation of the press is materially facilitated.
In the drawing, the letter A designates the foot-block of my press, which connects, by uprights B B, with the head-block (J. The uprights B form the guides for the follower D, and from this follower extends a standard, E, through a mortise of the head-block. The follower and the head-block are connected by toggle-levers F, the inner ends of which are pivoted to traveling nuts G, through which extends a right=and-left-hand screw, H. By turning this screw-spindle the nuts G are caused to move toward or from each other,
and the follower D is depressed or raised. The screw-spindle passes through a mortise, a, in the standard E, and on said spindle are placed loosely two disks, 1) b, one on each side of the standard. These disks are retained in position by stops 0, secured on the spindle H, and they are provided with hubs d, which project into the mortise of the standard E. By these friction-disks, therefore, the spindle is prevented from moving in the direction of its axis, and at the same time it cannot bind in the mortise of the standard, since the hubs of the disks retain it securely in position.
Instead of placing the friction-disks b b close to the standard E of the follower, they may be arranged, as shown at 12* 12*, on the outside of the uprights B, and in this case the hubs of said disks project between the standards and bear against them. The stops 0* 0* will then be placed on the extreme ends of the screwspindle.
By the arrangement of these friction-disks the operation of the press is materially facilitated, the screw-spindle is not liable to be thrown out of its proper position, and in operating the press much power is saved, while at the same time the durability of the press is materially increased.
What I claim as new, and desire to secure by Letters Patent, is-- The disks 1) b or b b having projecting hubs, and arranged loosely upon the endless screw H, and contiguous to the standard E or B B, and retained in place by stops, in combination with the toggle-levers F, traveling nuts G, and follower, all constructed and arranged as herein shown and described.
