Immediately in the rem-*of thelfeed-wheel bythe'incline, a, is placed-in, position-uponthe oapipltegto which it is' firmly fsstenedf, This incline iejntended to conv'eythe staples t'the fcedovheel b, tlieybeidg plsoed edge of `the inolinefdomi which s"u n opening"- in the top of (the upon it in iuoh'monner-thattho bow` or bent portion-)till rest upon the uppei they slide by their ownv weight.

, and arranging-the several partspf the another s np'porting-device, in for-m of uY knuckle# l additional mechanism, which I will proceed to describe.

Staples -havng been hung. upon the incee d, upon communica-ting motion tol the bell-eranlc C, by tripping thetreadle, the staple-notch or tongue 11 will be brought into proper position with regard to saidincline; and a staple irill be deposited by -its own weight up'onfsad tongue 11. Relaxing the pressure of the foot upon the tfeadle causes the partial rotation of the feedfwheel b by the action oi' the spring under .said treadle, and the staple is carried down the concave slots or grooves 12 in cap-plate e. Tho machinethen assuming the position shown in gn, these slots 12 are eut a suicient distance back of the-central rib to prevent the ends of .the

staple from catching, and thus be impeded in its passage down said slots. -T'he staple by its own weight then passes through the opening in cnpplate e, and is deposited in the driver-box,immediately in front ofthe end, 9, oi' drivel- W. The next stroke of the machine forces the `staple out..oi` the box and into the slnt.- As showt. in iig.' 7, pla'te 2, the staple-notch 11 has heen carried back, lby this movement, to a proper position to receiv` another. staple from the incline @and by eontinuingth operation any. numberof slats may be properly wired.` l

The operation of'aliixing or wiring the slats te the-rod or bnr L, figs. 12 and'13, involves the.use of `The hell-crank s, iig. 1, is attached to the bed-plate motion received from the bell-crank C to other parts, which'willbe described. The connectionbetwen the bell-cranks s and C is made by the rod u, (scc fig, 1,) it beingfastene'd by one of its 'ends to the end, l, of the bell-crank s, by a knuckle-joint attachment, and hasrits other end provided with a hook -that cambe connected to ordisengnged'fi-om the upright arm ofthe bell-crank C, as may be desired, a piu or stud, z,'i:i`g.`1, projecting from the side ot` said arm for its.accouimodation. The other end, 2, of bell-crank s connectsby the link 3 to the latch-carrier 1. This carrier is a piece of metal, shaped substantially as shown in iig. 1, and is rigidly fastenedto the guide-bard' Said bar issimply a piece ot' metal of properlength, being square in its body, and

-slidcs 'against a ledge or shoulder formed on the bed-plate A. vIt is retained in place by the clips-or binders c c,

essere i Y It will be observed that upon actuating the arm of bell-crank 0,a reciprocating motion is given to the guide-bar 4, moving-it in a line at a right angle to the 'direction in which the staple-driver W moves.

'Theguiding-rgller N, attached to the bracket R, is intended totake the position occupied by the slut-bed n, lnhich is removed. A perspective view of the bracket and roller is shown in iig. 8. Saidbrncknet is held in place by a stud or screw-bolt fastened to its under side, and clamping it by a set-nut, 14, to thebed-plate A.

The guiding-roller N isintended to hold down in place the-gauge-bar I and blind-rod L, and alsoV facilitate` the sliding of the blind-rod L, that is laid upon and clamped to'the gauge-bar I, Vduring the'operat-ion aftasten ing the slats to said rod. p p

' The bracket R, that carries the guide-roller N, is'further provided with a binding foot, F, upon its front Y face, that is designed vto assist in retaining in place the blind-rod L. p

The gauge-bar I is a strip of metal or other proper material, having its sides parallel, and its ltop face, (upon which the blind-rod lies,) hevelled, as shown fin iig. 10,-and also in iig. 13, plate.2. Said bar is provided with p pin's or studs i that are inserted or fastened in the side next the latch-carrier.1. These pins are placed an equal distance apart, said-distance being the saule as the space desired to intervene between the staples` that di; o1" fasten the slats to the blind-rod. Y p i p The latch 5, shown in perspective Ain fig. 11, is attached to the latchfcarrier 1, so as to play freely upon its rivet, and is intended to rest Aup'on and press against the pinsl and at each full s troke of the machine said latch is moved back a sucient distance to ingage with thevpin immediately'in its rear. It isili-tended to A be understood 4that'when the staple-driver, is fully thrown forward this movementtakes place. The return` stroke, caused 'by the action of the spring-treadlc, throws the guide-bar 4 forward, and consequently 'moves the gauge-bar I with it. l

The gauge-bar l ispartly guided and retained in place by the `pinsbn nf, that areusertedin 4bed-plate AL. Rollers may be substituted if desired; l

The front end of the driver-box is `cut away, upon the side upon which the yslats `are held, during the operation of wiring them to the rod. Theshapegiven to it is shown in iigs. 4, 7, and 12.

A shoulder-,is also formed on the front fac'eofV the driver-box, underneath the opening or passage in which the driver slides. Upon this shoulder thestaple in the slat rests, ivhen said slat-islput in position to be wired to the rod, as seen in figs. 4 and vl2'. The depth of the shoulder is such that..-the staple, being insertediu the blind-rod, will readily pass into the staple on the slut, and thus fix erfasten it in place on the ro'd,' as shown ing.12. i .K i

The position of the staple und shoulder on the driver-box is shown in iig. 9.

The several parts of the machine being arranged, nsdescribed,the 'manner of operation is evident'. The blind-rod Ljbeing placed-:in position on the gauge-bar I, and fastened to it, and staplesrbeing placed upon the incline a, all that is necessary is to place the staple, that lis in the slat, in position onthe shoulder on the face of the driver-box, as shown in-.ig.-4, andby giving motion to the bell-crankC, a staple will 'be inserted in the blind-rod, at the saine time coupling or fastening4 the slat to saidfrod the'operation being `repeated until the rod @is filled, or the proper number of slats attached to it..

A The advantages' obtained by this method of constructing blind-wiring machines, are substantially as fol`- n lows: First, tlteftnotionoffthe working parts is positive and absolute, whichmalies `the machine reliablein its action. Again, frein the peculiar methhd of constructing the feeding-mechanism, it is impossible to get more than one staple in the machine at a time, and every staple'must be driven home a. proper distance before the machine will receive another. Again, iti the operation of fastening the slats tothe blind-iod, every slet is placed an equal and correct distance-from its fellow, and a staple cannotbe inserted in the -rod unless the proper space between at a point, s', and is intended to communicate said slats is obtained. The whole of theparts sre simple inl urable, being `umdesnf' metal. Tli'ey are-nlsn easy to construct, and not liable to derimgementz.l l

.Having thus given avfull, clear, and exsct descriptionofmyimprovement, both vas regrds its eenen-actionJ and manner of operating, and set foi-th its merits, what I /elam as new of my'invention, amldesire to secure By Letters Patent of the .United States, .isl 1. Feeding the staples t the 'driver W by means of'vthve wheel '5, said wheel'beingl constructed and operating substantially as described. i

2. -The staplefsup'plying incline a, in 4eombinaton with the feedingfwheel'b and driver .W, arranged tn oper.

ate in the manner and by the means substantially as set forth. Y
