SFEGIFICTION forming part of Letters Patent No. 491,253, dated February 7, 1893.

Application filed September 5,1892. Serial N .445,095. (No model.)

To @ZZ whom t may concern.:

IBeitknown that I, FRANK J. STOLLE, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, haveinvented certain new and useful Improvements in Cloth-Notchers; and l do hereby declare the following to be a full, clear, and exact description et the invention, reference boing had tothe annexed drawings, which term part of this speciiication.

My invention comprises a cheap, simple and handy implement wherewith a number of pieces or cuts of garments can be readily notched at suitable intervals to enable the various parts being finally put together exactly as intended by the designenthe peculiar construction of said implement and the method ot operating it being hereinafter more fully described.

In the annexed drawingsr-Figure l-is a side elevation of a cloth notelier, embodying my invention. Fig. 2-is a front elevation of the saine. Fig. -eis a vertical section ot the operative parts of the implement taken in the plane of the knife. Fig. Ll--is vertical section o the reciprocating frame and its accessories. Fig. 5-is a front elevation of the presser foot carrier detached `from said fra-me. Fig. 6--is a horizontal section of the implement taken at the line Z--Z of Fig. l. Fig. TMs a plan of a soft metal disk that admits the point et the knife. Fig. S-shows the devices ior adjusting said knife. Fig. 9- is a plan of the cloth-gage detached from the implement. Fig. lO-is an enlarged plan of thepresser-footand its accessories. Fig. Il is an enlarged elevation of the upper portion of the lookin g bar of the vertically-reciprocating frame.

,Af-represents a cloth-plate, the front end of which, c., is chamfered oft so as to readily slip under the goods or cuts to be notched. l3.is a standard projecting vertically from this cloth-plate and having a longitudinal slot h, ot such a size and shape as to readily adinit the operators lingers. C. O,--are brackets projecting laterally from the front of this standard, and provided at their ends with guides c. c. c. c', that enter longitudinal grooves d. d, in the inner edges of vertical sidebars l). D, 'the ends ot these bars being rigidly secured to cross pieces F.. E', as more clearly seen in Fig. 4. Situated between these bars, and parallel therewith is a locking bar F, having either a lever f, as seen in Figs. l, 3 and e, or provided .with a hole f', as represented in Fig. ll, to admita pointed tool capable of turning said bar either to the right or lett. Furthermore this bar is journaled eceentrically in the cross pieces E. E', for a pur- 6o pose that will presently appear (see Fig. ll). These parts, D. D', E. E', and F, constitute what I term the vertically reciproeatin g trame, because it travels up and down every time the implement is operated.

(uh-is a tubular attachment having a pair of upper bearings g. g. and a pair of lower bearings g". g', which devices are adapted to travel along the side bars D. D', as seen in Fig. 2. Projecting rearwardly from this at 7o tachment is a lug I-I. perforated at h, as seen in Fig. ll, to admit the locking-bar F. I. I.- are rods extending down from said attachment and having the presser-foot J. secured to them, the latter having an opening j, made in it, as seen in Fig. l0. These devices Gr. H.

I. I', will hereinafter be designated as the presser-foot carrier. The tubular part G. of this presser-foot carrier is traversed by a vertically reciprocating plunger K, having at top 8o a button 7e, and at bottom a slot 7e", to admit a pointed knife or cutter L. Z.-is a slot in this knife to permit its vertical adjustment, after which act said knife is clamped in place by a tightening screw Z.

Z.are iilling pieces that may be inserted between the knife and the upper end of slot 7a', to prevent said knife working up by constant use.

M.is a spring coiled around the plunger 9o K, and serving to retain it in a normal or elevated position.

N.-is a vertical post against which the back of the knife bears, while the pieces of goods are being notched.

o. o', are stop pins projecting vertically -from the front of a gage-plate O, that slides within a longitudinal slot b, at the base of standard B, as seen in Fig. 3, the rear end of said plate being turned up at o, and adapted too to receive a set screw P.

lim-is a soft metal disk let into the plate A,

and having a pit fr, to receive the point of the knife.

S.is a handle pivoted at its rear end s, to the standard B, and maintained in a normal or elevated position by a spring s', the front portion of said handle being forked at T. T, to clear the sides of said standard. t. t.-are pins or screws that couple said forks to the lower ends of side-bars D. D.

The dotted lines, U in Fig. 3 represent a eut of patterns or garments resting upon the cloth-plate and notched by the knife.

V.-is a stop projecting from the back of plunger L, and r, is a vertical slot in the presser-foot carrier for this stop to traverse when said plunger is elevated.

The method of using my notching implement is as follows: The bar F, is rst turned in its bearings E. E', so as to liberate the presser-foot carrier G, and thus allow the latter to be adjusted either up or down to enable the cut or pack of pieces U, to readily enter between the plate A. and foot J, after which act, said bar is turned back, thereby locking said carrier tothe frame D. D. E. E', it being understood that the latter is now elevated by the spring s and the bar L, brought in contact with the lower bracket C', as seen in Fig. l. The next step consists in properly adjusting the stops o. o', which adjustment is accomplished by turning the screw P, the gage-plate O, being advanced for a shallow notch, while a retraction of said plate affords a deeper notch in the goods. The implement is now presented to the edge of the eut, which readily slides upon the cloth-plate A, because its advancing end is chamfered off at (L, and then the handle S. is grasped and pressed down with some degree of firmness. Consequently the reciprocating frame D. D E. E', is forced down, and with it the carrier G. and its attachments, the result being to tightly clamp the cut between the presserfoot and clotlrplate, as indicated by dotted lines in Fig. 3. A quick blow with the hand is then given to the button or knob 7c, so as to drive down the plunger K, until it is arrested by the stop V. coming in contact with the post N. This act causes the knife L, to notch the entire eut from top to bottom ata single stroke, the plunger being immediately restored to its normal position by the spring M. The operator then quits his grasp of the handle S, thereby permitting the spring s to elevate the frame D. D E. E', carrier G. and presser-foot J. The implement is now Withdrawn from the cut, reapplied to it in another place, and the above described operations are repeated as often as may be necessary.

From this description it is evident my implementwill cut th rough any reasonable thickness of cloth or other similar material, and will hold it im movably in place while the notch is being made. It is also evident that by providing the plate A, with a sharpened or beveled end a, the device can be readily slipped in under the cut, thereby preventing any derangement of the various pieces of eloth.

By making the tube G. and plunger K. square in transverse section, as seen in Fig. G, there is no danger of said plunger twisting around and throwing the knife out of line with the pit r.

Finally, in this specification where the word cut appears, it is to be understood as referring to a number of pieces of cloth, or other pliable materials, which have first been temporarily fastened together and then reduced to a proper shape to form certain parts of garments, the.

I claim as my invention:

l. The combination in a eloth-notcher, of a cloth-plate, a standard projecting therefrom, a vertically reciprocating frame applied to said standard, a handle coupled at its opposite ends to said standard and frame, a spring for restoring said frame to its normal position, a vertically adjustable carrier applied to said frame and provided with a presser-foot, a reciprocating plunger traversing said carrier, and a knife secured to this plunger, for the purpose described.
