LEATHER-CUTTER SPECIFICATION forming part of Letters Patent No. 273,018, dated February 27, 1883.
Application filed December 23, 1682. (No model.)
-To all whom it may concern: T-knife O oscillates freely but snugly in aslot,
'Be it known that I, WILLIAM BRIGG, a f, formed in the head of the anvil-jaw A,while citizen of the United States of America, residthe cross portion passes in front of the proing at WVashingtomin the District of Ooluinjectionf. The slotfcontinues down the front 5 bia, have invented certain new and useful lmof the head, as shown atf and terminates in provementsin Leather-Gutters, of which the the T-slotf which corresponds with the cutfollowingis aspecification,reference being had ting-edges of the knife G, as seen in Fig. l; or therein to the accompanying drawings. the slotsf f may be omitted, as seen in Fig.
i Myinvention relates to devices for forming 2, and the knife 0 may be formed so as to 10 the strips or brushes used in cleaning cottonhave the cutting-edges strike squarely on the gins; and the novelty consistsin the construcbed A of the jaw A. The plate 0 is detion and arrangement of parts, as will be more signed to cut a slit in a strip of leather or fully hereinaiter 'set forth, and specifically other proper material at right angles to a pointed out in theplaims. I straight edge thereof, and the cross-plate C 15 The invention is designed for service in to cut a slit parallel with such edge, the cenforming the brushes which are used in conter of which latter slit shall form a junction nection with cotton-gins of the class patented with the inner end of the slit formed by the to me October 28, 1879, No. 220,957, and it is cutting-edge of the plate G. fully illustrated in the accompanying draw- For the purposes aimed at by this invention 20 ings, which form a part of this specification, it is necessary that the firstnamed slits-that and in whichis, those cut by the cutting-edge of the plate Figure 1 is a perspective view of my inven- Oshould be varied in length as occasion may tion with the gage-platesremoved; Fig. 2, a require, and to accomplish this end I provide detail perspective view of the jaw, of somea gage composed of bars J, held in position 25 what different form, with the duplex gage in by set-screws s, passing through aperturesj position; Fig. 3, a detail showing the cuttingin the opposite ends of the arms J, and havedge of the removable cutter so formed as to ing their ends riveted in the gage-bars J, by incline the material toward the gage, and Fig. which means said gage is adjusted at will. 4 shows another modification of thejaw. When the anvil-jaw A is formed as shown 30 Referring to the drawings, in which similar in Fig. 2, it is necessary that the inner corner letters of reference indicate like parts in all of the cutting-edge of the plate O should apthe figures, A and B represent two cross-levers, proach very closely to the front A of the head pivoted ate, the lever A carrying the anvilat the latter part of its stroke, in order that jaw A and having socket on, and the lever B the extreme edge of the leather or other ma- 5 having the hammer-jaw B and provided with terial should be severed at that point when aprojection, b, whichisreceivedintothe socket the gage is not employed, and the said front 1 a, where the handles are forced together to A serves the function of a gage.

It is also important that the location of the 0 represents a removable T-knife secured slits should be arbitrarily exact, and when in the slot 12 formed in the head B, as shown. the guide-plate is used and a certain length 5 This knife is formed of the main plate 0, the of edge-slit is required I provide a knife the width of which is arranged parallel to the longicutting-edges of which incline upward in three tudinal plane of the levers. and a cross-plate, directions from the point 0, as the incline in a G the said parts 0 and 0 being formed in one downward direction might have a tendency to :00 piece, and the lower portions of each being force the material away from the gage.

the essential features of which have been freely described and illustrated.
By this invention I am enabled toforni a brush for the purposes described without the necessity of employing expert labor, as any novice can use the device successfully, and 1 am also enabled to effect a saving in time and labor--say two or three daysin the formation of a brush for each cotton-gin, which saving, in connection with thousands of gins now in use, will be an immense ad vantage, as will be obvious.
It will of course be understood that theface of the bed-plate A may be formed of or provided with a plate of soft metal, if desired, which may be secured in any convenient way,
or may be cast in the form shown in Fig. 4, in
which L represents the plate, provided with gage-arms J and a set-screw,j by which the length of the edge-slot may be gaged. This plate may be made of any suitable metal; but I prefer brass.
I have shown the device as operated by cross-levers, in the manner of shears; but it is obvious that other arrangements of means may be employed with equal efficiency.
Having thus fully described my invention, what I claim, and desire to secure by Letters Patent of the United Stat-es, is-
1. In a device for forming brushes for cotton-gins,aT-knife having longitudinal and transverse cutting-edges,and operating means,
substantially as described, combined with a bed and a gage-surface arranged at right angles to said bed, and constructed and arranged to have the inner corner of the longitudinal 3. In combination with a gage and a slotted bed and guide, a T-knife having its cuttingedges inclined outwardly and upwardly from their point of junction, as set forth.
4. The removable T-knife O, composed of the plates 0 and and having cutting-edges inclined in different directions from the point 0, combined with the bed A having slotsf front A having slotf and head having slot f, as and for the purposes set forth.
5. The knife 0, as described, and anvil-jaw A, having slotsff f combined with the adjustable gage J, and adapted to serve as set forth.
6. The duplex gage J, arms J, having apertures j, and the set-sorewsj, combined with the jaws A A, knife 0, and guiding-slots ff f, as set forth.
In testimony whereofI affix my signature, in presence of two witnesses, this 18th day of December, 1882.
WILLIAM W. BRIGG.
