EMBROIDERY-TRIMMING APPARATUS.

Specification of Letters Patent.

Patented July "Z, 1914.

Application filed September 3, 1913. Serial N 0. 787,827.

To all whom it may concern:

Be it known that I, FREDERICK PRIon, a

citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Embroidery-Trimming Apparatus, of which the following is a specification. My invention relates to improvements in embroidery trimming apparatus, an ob ect of the invention being to provide an im proved reciprocating cutter movable through a guide, which latter prevents the cutter from cutting too close to the embroidery, and also prevents the movement of the embroidery too far under the guide, hence insuring a uniform cutting of the embroidery, and a smooth rather than a ragged edge.

A. further object is to provide an improved apparatus of this character which will rapidly and accurately cut the edge of the embroidery, and .which is capable of adjustment for various operations.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings: Figure 1 is a view in side elevation illustrating my improved apparatus. Fig. 2 is a View in vertical section on an enlarged scale illustrating the cutting means per se. Fig. 3 is a view in section on the line 3-3 of Fig. 2. Fig. 1 is a plan view of an ordinary piece of embroidery. Fig. 5 is a face view of the cam 7. Fig. 6 is a perspective view of the guide 18. Fig. 7 is a perspective View of the guide supporting bracket 12, and Fig. 8 is a perspective view of the cutter *bar'19.

1 represents a base plate having a frame 2 thereon, the latter providing a vertical cylindrical guide sleeve3 at its free end supporting a reciprocating plunger 4. This plunger 4 is provided with a pin 5 projecting through a slot 6 in the guide sleeve 3, and into a groove 6 in a cam 7. The cam 7 is secured upon a shaft 8 which may be driven in any approved manner and it will be noted that the cam is provided with a plurality of cam surfaces so that at each revolution thereof, the plungers will be reciprocated a number of times. A cutter 9 is secured in socket 10 in the lower end of plunger 3 by means of a set screw 11. This cutter 9 is triangular in cross section and has a beveled lower cutting end.

12 represents a bracket which has a slot 13 therein for the reception of a screw lt to adjustably secure the bracket to the guide sleeve, permitting a vertical adjustment of i said bracket. The lower end of the bracket 12 projects at right angles to the guide sleeve, and is provided with a socket 15 into which the shank 16 of my improved guide 18 projects. The guide 18 is secured by means of a set screw 17, and may be adjusted horizontally to exactly position the guide under the cutter. By reference particularly to Fig. 6, it will be noted that this guide is of general triangular form, and corresponds in shape to the shape of the cutter in cross section.

On the base plate 1, acutter bar 19 is adjustably secured by means of screws 20, said screws being positioned in any of a plurality of threaded openings 21 in the base plate so as to position the cutter bar with any of its V-shaped notches 22 in register with the cutter. The bar 19 may have any number of these V-shaped grooves, so that as such edges become dull, the cut ter bar may be shifted to present other edges for cooperation with the cutter. As the cutter passes against the wall or edge of the notch 22, it exerts a shear cut so that the goods 23 may be readily cut. The guide 18 is located in a horizontal plane above the cutter bar just sufiicient to permit the goods 23 to pass under the guide, but not sufficient to allow the embroidery 24 to pass under the guide. In other words, this guide 18 prevents any possibility of the goods being moved to a position to be cut by the cutter, and the thickness of the walls of this guide controls the cutting, so that it is impossible for the cutter to sever the embroidery or to injure the same. To facilitate this protection of the embroidery, the guide 18 at its lower edge is projected downwardly forming a V-shaped bearing 25 which rests directly upon the goods as shown clearly in Fig. 2.

To prevent possibility of the cutter injuring the fingers of the operator, a guard 26 is secured to the guide sleeve by means of a screw 27. An opening 28 is provided in the base plate 1 below the cutter, so that the goods which are cut may fall therethrough, and furthermore, this opening prevents any possibility of the cutter engaging the base even though it is adjusted to its lowest po- I the surface of cutter bar 19 and moves the goods backwar'dly and forwardly toward and away from the guide 18. The guide allows the goods to be manipulated so that the cutter will cut into the angles of the embroidery, yet prevent any possibility of cutting the embroidery.

Various slight changes might be made in the general form and arrangement of' parts described without departingfrom my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appendedclaims.

, Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. An embroidery trimming apparatus comprising. a support for goods to be out having a notch in one edge, a guide positioned above the support a distance approximately the thickness of the goods to be cut, and a distance appreciably less than the combined thickness of the goods and the embroidery, said guide having at its free end a I downwardly extending V-shaped bearing adapted to rest directly upon the goods, and a cutter adapted to move through the guide and cut the goods against the wall of the comprising a support for goods to be cut l'having a notch in one edge, a guide positioned above the support a distance approxi-' notch, substantially as described.

'2. An embroidery trimming apparatuscomprising a support for goods to be cut having a notch in one edge, a guide positioned above the support a distance approximately the thickness of the goods to be cut,

and a distance appreciably less than the combined thickness of the goods and the embroidery, said guide having at its free end a downwardly extending V-shaped bearing adapted to rest directly upon the goods, and a cutter conforming in shape to in shape to the shape of the notch, said outter movable through the guide and adapted to cut the goods against the wall of the notch, substantially as described.

3. An embroidery trimming apparatus comprising a support for goods to be cut having a V-shaped notch in one edge, a

triangular guide positioned above the support a distance approximately the thickness of the goods to be cut, and of a distance extending V-shaped bearing adapted to rest directly-u-pon-the goods, and a triangular cutter adapted to reciprocate through the guide and cut the goods against the wall of the notch, substantially as described.

.4. An embroidery trimming apparatus, comprising a base plate having an opening therein, a supporting frame, a cylindrical guide on the supporting frame, a reciprocating plunger in the guide, a cutter in the lower end of the plunger in line with, the opening in the base plate, a cutter bar adjustable on the base plateand having a plurality of notches in its edge, said plate adapted to'be'moved to position any ofv said notches in line with the cutter, a guide through which the cutter reciprocates, said guide positioned between the cutter and the cutter blade and adapted to rest at its lower edge upon the goods to be cut and engage the embroidery, means for reciprocating the plunger, and a guard on the guide located in front of the cutter,- substantially as described.

5. An embroidery trimming apparatus mately the thickness of the goods to becut, and a distance appreciably less than the cutter of the same shape in' cross section, said cutter adapted to cut the goods against @thev notched edge of the support, substanitially as described. the shape of the guide and also conforming 1 In testimony whereof I have signed my FREDERICK PRICE.
