SPECIFICATION forming part of Letters Patent No. 520,535, dated May 29, 1894.

Application filed October 27, 1893. Serial No. 489,245- (No model.)

To all whom it may concern.-

Be it known that I, GEORGE E. NoRRIs, of Troy, in the county of Rensselaer and State of New York, have invented new and useful Improvements in Machines for Turning Oufi- Blanks, of which the following is a specification.

This invention relates to improvements on machines for folding blanks for cuffs, and other similar articles, and the object of my invention is to provide facilities for turning the edges of said blanks mechanically. I attain this object by the mechanism illustrated in the accompanying drawings which are herein referred to and form part of this specification.

In said drawings, Figure l is a plan view of my cuff-blank folding machine, removed from its supporting-frame, and showing the templet in its rearward position. Fig. 2 is a like view, showing the templet moved forward to a position for effecting the preliminary turning up of the edges of a cuff-blank. Fig. 3 is an end elevation of my machine supported on a frame (the latter being shown broken apart). Fig. 4 is a front elevation of my machine removed from its supportingframe. Fig. 5 is a longitudinal section of Fig. 2 at the line X X. Figs. 6, 7, and 8 are enlarged details showing different positions of the folding mechanism in the operation of folding a cuff-blank. Fig. 9 is an enlarged detail of one of the spring-guides for the cuffblank; and Fig. 10 is a detached detail of a sliding-plate for imparting movement to the folding mechanism.

As illustrated in the drawings, my machine is adapted to folding cuff-blanks for making ends with rounded corners, but it is equally adaptable for other forms of culfs without further invention.

As represented in the drawings, A designates the bed-piece of my machine, which can be made in the form shown, or in any other form suited to the purpose.

B designates a movable-bed that is fitted to acquire aslight vertical movement in an opening, 1, formed in the top of the bed-piece A, said movement being given for effecting the pressing-down of the folds formed on the edges of cufi-blanks by the folding mechanism. The movable-bed B is maintained in a mixed illuminating-gas and air, which are emitted from a perforated pipe, 2, arranged directly beneath said bed; said heating arrangement, being old and well-known, forms no part of this invention.

0 designates a sliding-plate that is fitted to move in a recess, 3, formed in the top of the bed-piece A, and said sliding-plate is provided with studs which carry friction-rollers, 4, on its upper face; pendent from the lower face of said sliding-plate, lugs, 5, are formed, and a rocker-shaft, D, is j ournaled on said bedpiece and is provided with a double arm, 6, having a roller, 7, pivoted thereto and fitted to engage between the lugs 5 for the purpose of imparting a sliding movement to the plate 0, a handle, 8, being secured to the shaft D for the purpose of imparting a rocking movement to said shaft.

E designates a pair of folding-plates that are arranged to slide diagonally on the top of the bed-piece A; said folding-plates are held down, to resist the upward pressure of the movablebed B, by means of bars, F and G, the first of which is arranged longitudinally, and the others transversely on said bed-piece, upon which they are secured by bolts, 9, so as to allow the plates E to slide easily; at the outer end of each of said folding-plates a pair of swinginglinks, 10, is arranged to produce a diagonal movement of said plates, one end of each of said links being pivoted to the corresponding folding-plate, and the opposite end being pivoted to the bed-pieceA by the pivot-bolts,11, which are adjustable in holes, 12, in the bedpiece, so as to adapt the machine for folding blanks for difierent lengths of cuffs. An opening, 13, is formed in each folding-plate for the purpose of allowing a diagonal movement of said plate notwithstanding the bolts 9 atthe ends of the bar F. The adjacent ends of the folding-plates E are slotted, as at 14, to receive the friction-rollers 4. of the sliding-plate, so that the movement of the latter will effect a simultaneous movement of the folding-plates, the direct inward and outward movements of the sliding-plate 0 being converted into diagonal movements of the folding-platesE by means of the links 10. At the inner end-or the end which abuts against the other folding-plate-a detachable piece,

suitable heated condition by means of jets of 15, is attached to each folding-plate so as to adapt the pair of folding-plates to meet centrally when adjusted for folding blanks for cuffs of different lengths; said detachable pieces being attached to the folding-plates by means of bolts, 16, and dowel-pins, 17both of which are indicated by dotted lines in Fig. 1. The inner portion of each folding-plate is cut out, as at 18, to conform to the shape of a cuff to be folded thereby, and a recessed edge is formed about the cut out portion to produce a ledge, 19, on which the material for a blank can be laid in place preparatory to the operation of forming the fold on the blank, but, when preferred, said folding-plates may he made without the ledge 19, and other provision may be made for fixing the blanks in arequired place, as for instance,pins or stops may be fixed on the folding-plates to indicate the position of the blanks thereon.

H designates a templet, or form, of sheet metal, corresponding to the form of the folded cud-blank, which is attached to a plate, 20, of wood-or other material, that is secured to the swinging end of a bracket, 21, hinged, as at 22, to a slide, 23, arranged to move on guide-bars, 24, projecting rearwardly from the movable-bed B, and provided with a crossbar, 25, which forms a stop for limiting the rearward movement of said slide; the slide 23 is provided with lugs, 26, which form part of the hinge-joint for the bracket 21, and which may be arranged totake against stop-bolts, 27, adjustably inserted in the bed-piece A for the purpose of limiting the forward movement.

of the slide 23. The bracket 21 is provided with a knob, 28, or other handle, to enable an operator to manipulate said bracket and the slide 23 to which said bracket is hinged.

I designates adjustable spring-guides which are fitted in grooves, 29, in the top of the movable-bed B and are provided with slotted openings for receiving bolts, 30, whereby said guides can be secured at any required point of their movement; the free end of each of said guides is bent downward, as at 31, to form a shoulder against which the rearmost edge of the unfolded blank will take in the operation of placing the blanks in the machine.

It should be understood that the object of making 'the guides I adjustable is to adapt the machine for blanks of different widths.

The downward bend of the guide I is arranged to lie in an opening, 32, in the movable-bed B in such manner that the arm of said guide can be pressed down into the groove 29 so that no part of said guide will project above the plane of the top of the movablebed B.

J designates levers fulcrumed, as at 33, to the bed-piece A, and so arranged that the shorter end of each lever will form a bearing for the movable-bed B, and to make said shorter ends adjustable bearings for the movablabed, each of them is provided with a spring-plate, 34, which will bear directly against the lower part of said bed, and setbolts, 35, are arranged to bear against the under side of the plate34; the longer ends of said levers are arranged to be adjacent to each other so that a collar, 36, on the rod 37, will bear upon the adjacent ends of both levers. The rod 37 is connected to a treadle, 38, arranged under the machine so that the foot of the operative can be readily applied thereto for the purpose of moving the lovers J to press the movable-bed B upward, the downward movement of said bed being effected by gravity, or by any other suitable means.

K designates a table or frame on which the machine rests,but the form of said table may be changed as may be desired.

The rod 37 is preferably'connected to an adjustable eye-bolt, 39, for regulating the dis tance between the treadle 38 and the levers J but, when preferred, the rod 37 can be provided with any of the well-known means for efiecting adjustment of the distance between the treadle and levers.

Myinvention operates in the following manner: The folding-plates E being adjusted to a particular size of cuffs (and it being understood that the lengths of cuflfs vary about a half inch in length between the different sizes, the detachable pieces 15 can be made to vary a quarter inch in thickness, to compensate for the different lengths of the cud-blanks and effect a central meeting of the folding-plates when adjusted for different lengths of cuffblanks,) a cuff-blank of the required length is placed on the ledge 19 of the folding-plates and the opposite edge of the cud-blank is fixed against the guides I; the templet H being raised up-as indicated by dotted lines in Fig. 3so as to clear the guides I, the operative draws the slide 23 forward, to bring the templet into position over the opening 18 of the folding-plates E; and then depresses the templet I-I, thereby pressing the cuff-blank down onto the top of the movable-bed B and turning up the material of the cud-blank to form an up-turned flange, 40, at the edge of said blank, as shown in Figs. 5 and 8; then, by means of the shaft D, and its attached parts, the operative moves the folding-plates E--in the manner previously described-to fold'said flange down against the body of the blank, as indicated by dotted lines in Fig. 7, after which the templet H is withdrawn from the folded blank, and the operative, by pressing down the treadle 38, moves the levers J to raise the movable-bed B, and thereby the cuff-blank will be pressed against the under side of the folding-plates E with sufficient force to complete the pressing down of the folds at the edge of the cuff-blank. By the inward movement of the folding-plates the surplus material around the rounded corners of the cuff-blank will be crimped in such manner that the subsequent pressure applied by the heated movable-bed B will effectually press out the crimps. After the blank has been subjected to a sufficient pressure, the

folding-plates E are moved back to their normal position, and the movable-bed B returns to its normal position, thereby leaving the machine in condition for a repetition of the operation just described.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a machine for folding cuff-blanks, the combination of a bed-piece, a movable head fitted to slide vertically in an opening in said bed-piece, a pair of foldingplates arranged to move diagonally toward each other, swin gin glinks pivoted to said folding-plates and bedpiece; said folding-plates having an opening which conforms to the shape of the folded cuffblank, a templet havingthe form of a folded cuff-blank and arranged to be moved over and depressed into the opening of said foldingplates, and levers fitted to press the movablebed upwardly against the lower face of said folding-plates, substantially as specified.
