COPYING-PRESS.

SPECIFICATION forming part of Letters Patent No. 726,840, dated May 5, 1903.

Application filed February 19, 1903. Serial No. 144,141. (No model.)

To all whom it may concern:

Be it known that we, LEONARD BAILEY, of Wethersfield, and WILLARD EDDY, of Hartford, in the countyof Hartford and State of Connecticut, have invented certain new and useful Improvements in Copying Presses, which improvements are described in the following specification and are illustrated by the accompanying drawings.

The invention relates to that kind of a screw-press which is commonly used in the operation of copying letters and other written or printed documents by moisture and pressure and is provided with a water-pan and a pair of pressure-rolls for the treatment of copying-pads, which are used in that operation. In presses of this kind the pressurerolls are mounted one above the other in the upper part of the press-frame, and the water-pan is adjustably seated below them. In some presses of this kind as constructed before our invention was made such waterpan has been detachably seated upon a movable support or lifter driven by a screw, and thereby according to the requirements of the occasion has been at times adjustably raised up for the purpose of wetting the lower roll and at other times lowered away from that roll for the purpose of being emptied and of being refilled with clean Water.

It is the object of the present invention to raise, lower, and support such water-pan for these purposes by means which are more sim-.

ple and convenient and to effect all necessary movements of such pan without the aid of any separate and movable lifter and without the aid of any screw or other driving mechanism. This object we accomplish by means of inclined ways, which are attached to the press-frame, and a pair of correspondingly-inclined shoulders or guides, which are located upon the ends of the pan and are adapted to engage such ways.

In said drawings, Figure 1 is a side elevation of a copying-press which is constructed in accordance with the principles of this invention and illustrates our best method of applying these principles. In this figure a portion of the water-pan is broken away for the purpose of exposing its contents. Fig. 2 is a section on the broken line a; x of Fig. 1.

Fig. 3 is an end elevation of the water-pan. Fig. 4c is a combined end elevation and vertical section of an upper part of said press without the water-pan. Fig. 5 is a like view of the same part of the press including the water-pan, which is shown approaching its normal position. Fig. 6 is a like view of the same part of the press, including the waterpan, which is seated in its normal position.

As shown in Figs. 1 and 2, the frame of the press consists of a base 1, which is of general rectangular form, two vertical posts 2, rising from that base, and a horizontal crown or cross piece 3, connecting these posts at the top, and thus completing the arch that spans the base, together with a pair of vertical arms or so-called uprights 4 and 5, which may be regarded as continuations of posts 2, respectively. The platen 6, the driving-screw 7, and the hand-wheel 8 all operating in a familiar manner require no description. In the upper part of the described frame and between the uprights 4 and 5 two horizontal rolls 9 and 10 are journaled in suitable boxes or hearings in the hangers 13 and 14, which are fastened to the uprights a and 5, respectively. These rolls may be set in motion by a crank 11 on the shaft 12 of the lower roll 10. As shown in Fig. 1, the under surface of shaft 12 is exposed for a short distance between the upright 4t and the hanger 13 and likewise between the upright 5 and the hanger 14. To prevent the copying-pads that pass between the rolls from following around the lower roll 10 and down into the water-pan, a thin metallic plate or stripper 26, as long as roll 10 and of uniform cross-section, is fastened to the uprights 4 and 5 near that roll and in approximately the same horizontal plane asshaft 12. Attached to the inner faces, respectively, of the uprights at and 5 or formed integrally therewith are two similar parallel and vertical plates 18 and 19, whose slanting upper edges form inclined ways on which the water-pan may slide, as hereinafter described. In the upper edge of each of these plates is a notch 20, and above them the uprights 4 and 5 are pierced, respectively, by the set- screws 25 and 25. Pan 15, which is shown separately in Fig. 3, is a shallow tank formed, preferably, of sheet metal and having parallel vertical ends and a general rectangular form. Its length is slightly less than the distance between the uprights 4t and 5. Centrally 1oeated or affixed upon the opposite ends, respectively, of pan 15 are two thin projecting shoulders 16 and 17. The lower edges of these shoulders have an inclination corresponding to the grade of ways 18 and 19 and are provided each with a point 21, which is adapted to catch into notch 20 of those ways. Pan 15 is also provided with two partial coversnamely, the fixed cover 22 and the detachable cover 23-which may have an uncovered space between them for the accommodation of roll 10, as shown in Fig. 2. In the middle part of the upper margin of each end of the pan, as shown in Fig. 3,is cut a graduallydeepening notch 24, whose longer edge is approximately parallel to the lower and bearing edge of the subjacent shoulder 16 or 17.

Such beingthe construction of our improved copying-press, its mode of operation is simple. The water-pan 15 after being supplied with water while separated from the press is brought by hand toward the front of the pressframe just above the level of the cross-piece 3 in a position which is indicated in the drawings by the position of Fig. 3 relatively to Fig. 4. Being then advanced in the direction of the arrow in Fig. 3 and without turning or tipping, the pan is inserted by the hand of the operator between the uprights 4 and 5 on either side and between cross-piece 3 below and roll 10 above, as shown in Fig. 5. As illustrated in that figure, the shoulders 16 and 17 are thereby brought into contact with the ways 18 and 19. Then as the pan is pushed by hand in the same direction and as said shoulders slide upon said ways the pan ascends obliquely and Without spilling until stopped by the contact of shaft 12 with the bottom of notches 24. At the same time the end walls of the pan enter one between the upright 4 and hanger 13 and the other between upright 5 and hanger 14, and roll 10, sinking through the opening between the partial covers 22 and 23, is partly submerged in the pan. When the operator lets go the pan in the position last indicated, the points 21 of their own accord slip into notches 20, as illustrated in Fig. 6, and the pan is thereby locked by its own weight in its normal working position, as shown in Figs. 1, 2, and (i. Resting in that position upon the ways 18 and 19 the pan is fastened there immovably by turning the setscrews 25. By turning back those screws and by tipping the pan sufficiently to raise the points 21 out of notches 20 the operator may release the pan and then by reversing its above-described movement may withdraw the same for refilling or for other purposes, as may be desired.

Such being the construction and operation of the invention, we claim- 1. In a copying-press, a pair of inclined ways, in combination with a water-pan, having a pair of correspondingly-inchned shoulders, which are adapted to slide onsaid ways, and automatically to interlock therewith when slid to a predetermined position thereon.

2. In a copying-press, a pair of pressurerolls, mounted one above the other, in combination with a pair of inclined ways, and a detachable water-pan, which is adapted to slide thereon to and from a position of en gagement with the shaft of one of said rolls.

3. In a copying-press, a pair of pressurerolls, mounted one above the other in the press-frame, a pair of inclined ways, occupying fixed and parallel positions in said frame, and a removable water-pan, which is provided with a pair of correspondingly-inclined shoulders for sliding upon said ways, in combination with mechanism whereby said pan, when moved to a predetermined position upon said ways, may automaticallyinterlock therewith.

4. In a copying-press, a pair of inclined ways, side by side and parallel, in combination with a water-pan, which is adapted to slide up and down said ways in a' uniform position, and mechanism for locking the same immovably in that position.

5. In a copying-press, a pair of pressurerolls, which are mounted in bearings in the press-frame, and a water-pan, which is movable obliquely up and down in that frame, in combination with a pair of inclined ways, which occupy a fixed position in said frame, and are adapted to guide said pan to its working position under said rolls, when it is pushed home by the hand of the operator.

6. In a copying-press, a pair of rolls, which are mounted in vertical series in the pressframe and a water-pan, which is provided with partial covers, having a longitudinal opening between them, in combination with means of sliding said pan obliquely upward and of thereby sinking the lower roll partly through said opening and into said pan.

7. In a copying-press, a pair of inclined ways, and a detachable Water-pan, having a pair of correspondingly-inclined shoulders, which are adapted to slide on said ways, in combination with mechanism for fastening said pan in a predetermined position upon said ways.

In testimony whereof we have hereunto set our names in the presence of two witnesses.
