IMPROVEMENT IN PRESSES.

Specification forming part of Letters Patent No. 34,996, dated April 15, 1862.

To all whom' it may concern.'

Be it known that we, RICHARD V. DEGUI- NON, of the city of Hudson, county of Hudson, and State of New Jersey, and GEORGE W. BARCLAY, of the city of Brooklyn,county of Kings, and State of New York, have invented and made a new and useful Improvement in Presses for Cutting, Stamping, and Bending Metal Goods, such as clasps and slides for hoops-kirts, harness ornaments,

buckles, buttons, 85o.; and we do hereby detached. Fig. 5 is a plan view of the bending- I `the bed-plate l5.

bar H detached. Fig. 6 is aplan-view of the guide O detached. Fig. 7 is an end elevation of the guide. Fig. 8 is aside view of the lever L broken off. Fig. 9 is a perspective view of the feed motion, the shaft N and upright AT being broken off. Fig. 10 isa perspective view of the spring-bender detached. Fig. 11 is a sectional view of the stud S, Fig. 9, showing the rocker-shaft 33. Fig. 12 is a perspective view of the end block O detached. Fig. 13 is a side elevation of the press. Figs. 14,15, and 16 are perspective views of the bending-punch detached. Fig. 17 is a perspective view of the bolster A detached. Fig. 18 is a perspective View of the bending-die 19, the lower side being turned up to show the pin 22. Fig. 19 is aplan view of the bedplate 15 15.

Like Inarks of reference indicate corresponding parts.

` The nature of our invention consists in making a press with various adjustable motions and so arranged that the two plungers work at. halt motion to each other-that is to say, while one is descending the other is ascending. The goods being cut by one die pass through the said die and are then Inoved by a mechanical device to the second die,

whereat they are bent or stamped, as the case may be. The cam for moving this device is so constructed that time is allowed at each end of its motion for the article cut to drop into the blank-carrier,when itnoves forward and remains at the other extent of its motion until the article is bent, or, if stamping, until' the impression is made. Thus one, two, or six articles may be cut, bent, or stamped at the same time. On the cutting-punch receding from the die the feed-rollers move forward and draw the strip of metal the proper This distance distance for t-he next cutting. can be graduated to the one-sixtieth part 'of an inch by means of the jam-nuts 6 6 6 6 on the levers G G', Fig. 9.

To enable others skilled in the art to Inake and use our invention, we will proceed to describe. its construction and operation.

le construct our press as seen in the perspective view, Fig. 1, the said press being made in its various parts of wrought and cast iron and steel.

The uprights T and U U U are cast fast to The bolster A, Fig. 17, is screwed to the bed-plate by screws 16 16, the said bolster-'having a groove-,lplaned for the blank-carrier F and `bending-bar H to move in. The die B and the guide C, the bendingdie 19, and stop 17 are screwed to thesaid bolster by screws, as seen at Fig. 17, Plate No. 2.

O, Fig. l2, is a steel end block slotted out to receive the end of the blank while being' bent, and keep the ends vertical while the middle is being bent over the bending-bar H, the said bending-bar having a corresponding slot 40, Fig. 5, made therein for a like `purpose. Between the blank-carrier F and bending-bar H is a parallel partition 7, (see Fig. 2,) upon which the blank drops when the blankcarrier F moves forward and carries the blank to the bending-die 17 where the blank -is bent, and on the withdrawal of the bending-bar H the slide (now complete) drops through the opening 26, Fig. 2.

Figs. l0, 14, 15, and 16 are perspective views of the bending device, showing them put to-4 gether and in a detached position. E E is made to slide freely up and down on the shank S, the lower part of the said shank being slotted out, as seen at Fig. 15, to bend the blank over the bending-bar H. E E is kept against the shank 8 by means of the spiral spring 3, Fig. 2, so that the bottoms are always parallel to each other, except when bending the middle of the blank downward, (see Fig. 2, 2121,) but on striking the bending-bar H the spiral spring 3 allows the shank 8 to descend and bend the middle ears of the blank. The blank-carrier F and bending-bar H are moved forward by means of the cam J on shaft N,

the lever I, the rocker-shaft 23, and stud S,

the said stud being made adjustable by means Vof slots 46 in the bottom of the stud, so as to shorten or lengthen the stroke of the blankcarrier and bending-bar, that the article cut -in bolster A.

Motion is communicated to the feed-rollers Q Q by means of the eccentric M on shaft N, (see Fig. 13, Plate No. 2,) the arms 32, the levers GG', and the hinged straps 33, the leverA G having a pall 35 working on the ratchet- 'wheel 36, the stud 30 being made fast to the upright T, by means of two bolts. (Not shown.) By moving the jam-nuts 6 6, &c., up or down, the'motion is increased or diminished according to the size of the article to be cut. The levers L L are moved by the eccentrics K K on shaft N. The plungers D and Dare kept al- Ways close to the end of the levers L L by means of the tie-rods 2 2 and the springs 5 5. The guide device C (see Fig.w6) is fitted with a guide 37 and sprin g 38, for the purpose of alllowing the metal strip to pass freelywhen one end of kthe said strip is wider thanthe other, as often occurs in cutting t-he metal;` The spring 38 presses the rguide against the strip of metal in such a manner that the metal is always pressed 'against the opposite side. Underneath the die B, Fig. 2, and through the partition 7 are drilled small holes 42, passing into a small chamber 41, the said chamber being connected with an air-pump, which produces when in motion a suction through the holes 42, thus drawing down the blank or article cut and preventing it from. bouncing up and catching in the blank-carrier, as would otherwise occur in 4working the machine ata high rate of' speed. We have two ways of producing this effect. The other arrangement is by introducing the air through the plunger D and punch or cutter 4, thus blowing the article cu-t on the partition 7 it under the bending device E E, Fig. 2. The

said bending device, descending, bends the ears marked 21 21 up and the one marked 54 down over the bending-bar H, whenthe said bending-bar recedes, and the end of the slide is drawn out of the end block O (see Figs. 2 and 12) by means of small notches 11 placed on the bending-bar H, (see Figs. 4 and 5,) or by springs placed in the end of the block O for the purpose of pushing them out. The bending-bar H still continues to recede,when the pin 22 throws the slide, nowr complete, out of the correspondin(r slot 40 in the bending-bar H, when the slide or article cut and now complete drops into the box beneath through the opening 26.

Having thus fully described our invention,

. what we claim as our improvement, and desire to secure by'Letters Patent, is-

1. yThe bending device, Fig. 10, the shank 3, being made fast in the plungerD, Fig.y 2,

by means of the pin l2, and having a Yspiral spring 3 or its equivalent Working on and around the shank of the iiXed bender 8 and pressing against the bottom of the-plunger D to keep the movable part of the bender E E parallel to the bottom of the fixed bender 8, except' when bending the middle of the blank, and working in combination with the blank-carrier F and bending-bar H, substantially as set forth.

- 2. The bendi-ng-bar l l and blank-carrier F,- working simultaneously with each other and in combinatioiifwith the bending-die 19, the whole'being'constructed and arranged and operated substantially as described.

3. The air-chamber 4l in bolster A, Figs. 13 and 17, the small holes 42 being drilled through the partition 17 for the purpose ofdrawing the blank down upon the said partition by means of an exhaust-pump or its equivalent, as herein speciied.
