Consequently the edge receives the coloring or iinisliing substance or preparation ifrom i the outlet'in being thus: fed. The requisite sup-v ply of tlie'isaid substance or preparation is furnished by means of a suitable filled reservoir uorcon-ta'iner, suchH for instance' as that from Fig.,y 3) having .its dischargingfnozzle bentered intoa chamber at, Fig@ 5,- in.

The ypassage aintersects the said c'hs'tniben'y so vthat the. coloring.y or* vfinishing substance or preparation,.1receivedl Within tion'edquantity, and` may Iadopt any 'oftvari-V ous forms of forcefeed devices suitablefor the purpose.'l The i illustrated' machinefcontains a 'preferred form of vmeans offsuch class,' comprising a needle-plunger c lwhich occupies the passage a and fis-givenfendwise reciprocating movements thereinw Insuch movements the plunger cause/5,: orrv iassistsfin causing; the coloring Tor finishing;l substance or= `preparationv to issue at'tlie' outlet fai, and in addition lprcvents clogging# of the i rp8S` sage and Sroutlet. The means-roffimparting the reciprocating movements tothe plunger c may be varied Ainepractice. Herein,-z.the said means comprises a rotating cam `cff'on the countershaft'cl at thefrearsofwthe.fm-af chine. i' and connections between tlie-.fpl'unger andthe 'said cam.v7 Such connectiglonsconsst in this* particular: instance"y off.: a1 plunger 6; a rod "cthavingfone end thereof connected Y endofthe said v rod isf connectedjland alberi- Zontal arm extending rearwardly beneath cani c and furnished with a rib cX shown best in Fig. 8, Sheet 2, against which said cam acts. The said bell-crank or rocker c5 is mounted between center-screws 050, c5, in connection with npst-anding supports 051, NH and is adapted to swing in a Vvertical or substantially vertical plane, in the direction from front to rear of the machine and vice versa. A spring c7, Figs. 2 and El, acts upon it oppositely with respect to the said cam to keep the rib cX in contact with the cam or the adjacent portion of the shaft d. It rocks in the said vertical plane upon said center-screws c5", 050, when actuated by the cam and spring, and by means of the rod of transmits movement to the bell-crank c2 so as to swing the latter and thereby cause the plunger e to reciprocate endwise within the passage a.

Preferably, the devices for ensuring feed of the coloring or finishing substance or preparation are contrived to operate as a lil) force feed, and the retracting inoz'en'ient of the plunger c is made sufficient in extent to withdraw its leading end into the chamber a* so as to afford `opportunity for the said substance or preparation to flow from the chamber into the portion of passage entending from the chamber to outlet c. In the projecting stroke of the needle-plunger, its leading end forces a small quantity of the coloring or finishing substance or preparation ahead of it through the said portion of the passage a, to the outlet a, said end reaching in such stroke a point close to the position of the edge of the material operated upon. This action causes the said quantity of the said substance or preparation to be delivered to the said edge closely adjacent the point at which the latter is subjected to the action of the tool.

The reciprocating action of the needleplunger takes place with such rapidity that a continuous supply of the coloring or 'linishing substance or preparation is ensured at the outlet a.

The use of a reciprocating needle-plunger is especially advantageous when employing a viscid quickly hardening substance or preparation7 such as a solution of Celluloid in amyl-acetate. The said device ensures a regulated feed at the outlet c and prevents the passage a and the said outlet from becoming clogged.

The avoidance of waste of the fluid .subn stance or preparation employed is attained in the illustrative machine through providing for control of the feeding of the said substance or preparation so that no feeding thereof shall take place in the absence of material to be operated upon, and so that feeding shall begin when a piece of such material is in position to receive such sub` stance or preparation.` shall continue while .the said 4piece is such pesitiein and 'shall in this instance the presser or hold-down i410,

although in some cases it may be another piece specially employed as a detector. rthe presser l() is movably supported in the machine by means of a presser-carrier al supported by a mounting llh Figs. l and 2, that is pivoted by meaiis of center-screwa 4t2, e2, upon the lined frame-part 22 with capacity to swing in a vertical plane so as to allow the presser to move to accoinniodate itself to the material when the leading end of the "r latter is inserted under 'the presser, and so as to provide for drnvnvard movement oi.' the presser when the material passes out; from under the presser. il, coiitracting.;- coiled spring all, Fig. l, connected with the presser-carrier holds the presser-carrier and presser toward the surface of annulus l0, yields to permit the presser to be separated from the said surface by the entrance of a piece of material between the two, and draws the presser toward the said surface when the material passes out from under the presser. rl`he position of the presser or other detecting member determines whether there shall be feeding of the coloring or lininshing substance or preparation, or the feeding shall be suspended ln practice, various arrangements may be employed for causing the feeding to begin when the presser is separated from the annulus. continue while the pressure remains separated from the annulus, and cease when the presser moves toward the annulus again. Herein such action is provided for by mounting the bell-crank or rocker c3 upon a laterally-movable carrier constituted by an upright arm 072. llie .said carrier arm is made laterally movable by being pivoted between center-screws c5". c5. on a supporting carriage Q and its lateral in ementl taking place under the control of the presser or other detector are adapted to place the bellcrank or rocker either in working relations with the cam o or out of working relations with the latter. Normally, the carrienarin is caused by the tension of a contracting coil-ed spring m, Figs. l and 4, to occupy a position toward the right hand side in F l, 3 and 4, in which it presents the rib cx, (Fig. 8) of theI hoi-is arm of bell-crank or rocker to a con itric or sabstan f concentric portion of the earn o' or rotan Y shaft al as in Fig. fl. @o long as the paw i occupy the position `inst referred to the ben- ,cranls er rocker is out @t working rela/tiens lOl) cam-portion of the Vproper eccentricity or throw, the desired length oi stroke is secured. This regulation is effected herein by shitting the acting end oi' the core ot the electro-magnet g in the required direction, so that when the armature 7c has been attracted by the energized magnet and moved toward the latter, accompanied by upstanding arm 052 and bell-crank or rocker c5, this action will carry the bell-crank or rocker either 'farther lengthwise oi the cam or not so far, as the case may be, and thereby place the horizontal arm oi the bell-crank or rocker in. working relations with the portion ot the cam which will give such length oit stroke. Gompensating adjustment of stop a will be made, ii necessary, to permit the spring m to return the bell-crank or rocker back to the portion ot least throw oit the cam, or the concentric portion of the cam or of the shaft d. This shift ot the acting end of the core of th-e electro-magnet is provided Jior in the present instance by malting carriage C adjustable transversely of the machine, so that by such adjustment off the carriage the electro-magnet in its entirety embracing the core is thus shifted. Herein, the said carriage is pivoted by means of a screw CX to bed-plate 12 so as to adapt it to be swung transversely about such screw. An arm Cy of the carriage is extended to the tront of the machine to serve as a convenient handle that may be, used by the operator for swinging the carriage in making required adjustments of the character just explained. I provide for varying the point reached by the plunger in its down stroke. That is to say, the closeness or" 'approach of the end oi' the plunger to the outlet. ln the present instance the rod c is made adjustable lengthwise. Its rear end occupies a hole through a connection-piece c41 that is pivotally connected to the upstanding arm oi bell-crank or rocker c5. After loosening the bindcrscrew 042, Fig. 2, which astens the rod c4 to the connection-piece, the rod may be shifted lengthwise to the necessary extent and then be secured in the position oi relative adjustment thereby attained by tightening up the said binding screw.

Referring now yto annulus The mounting 10b and annulus in this instance are yieldingly upheld by a sp 1ing 18, Fig. 1, upon which the. intermediate portion of the mounting rests. The lower blade or leaf of the said spring rests `upon a nut 13a upon a threaded stem 131? rising from the bed-plate 12. Through adjustment of the nut up or down upon 4the said threaded stein, the tension of the spring, and thereby the resistance which the. annulus Oilers to being depressed by work entering between it and the tool 20, may be regulated; and thereby the degree of the force with which the work is held in contact with the tool, and the efect produced by the tool upon the work, may be regulated. The .spring may be omitted it desired, as in the prior Letters Patent, and the nut alone be utilized to adjust the mounting and annulus up or down.

As a means of adjusting the closeness of approach of the working surface of the annulus 10 to the tool, to suit diiferent thicknesses of stoel; operated upon and vary the results secured upon th-e stock, I have provided the illustrated machine with an adjusting screw t, Fig. 1, applied in connection with a- Xed portion ot the machine-traine, said screw being arranged horizontally and having a conical end which engages with the upper side of an end portion oit the mounting 10l for the annulus. The action of spring 13, in pressing the mounting upward so as to lzeep the annulus up close beneath the tool, keeps the said end-portion oi the mounting in contact with the said conical end of the adjustment-screw. Such conical end constitutes a stop which delines the closeness oit approach ot the working surtac-e of the annulus to the tool. Adjustment of the screw end\.vise varies the said closeness of approach, according as larger portions ot the cone are presented in position i'or the end-portion of mounting 10b to engage therewith or are withdrawn so that smaller portions oi the cone are presentedin such position.

l provide for preventing portions of the material operated upon from being carried down at the inner periphery oit annulus 10 by the action oi' the tool 20, so as to produce a feather edge, by mounting the annulus so that it shall be movable toward the guide or gauge for the material-edge, and causing the said inner periphery to bear against the said guide or gaugeand extend across thel radial face, a, oi the tool, close to the said face. As described earlier hereu in, 'the edgeguide or gauge is` constituted by the end-surface of the casing a2 adjoin-:

ing the tool. lt surrounds the periphery of the radial tace '20a ot the tool. rlhe said inovability of the annulus is secured by providing i'or movement of annulus-carrier 10a transversely, in the present instance by pivl oting foot ot the annulus-carrier by means of center-screws s, Fig. l, to the said mounting, and herein the inner periphery of the annulus is caused to bear against the said endsurtace by the tension of a contracting Vcoiled spring s which is engaged with the annulusrarrier. The casing a2 is mounted upon the tree end of the fixed frame-part 22 through which the tool-shaft extends. lt is iixed adjustably in its working position by convenient means tor the purpose. llore in a clamping screw a, Fig. 5, is employed. In practice the said casing is adjusted laterally into a position in which it holds the inner periphery ot' the annulus just clear during the presence of the material, and suspendingits movements in the absence of the material.
