Application filed June 4, 1904. Serial No. 211,215.

To all whom it may concern:

Be it known that I, FREDERICK M. FUR- BER, of-Haverhill, county of Essex, State of Massachusetts, have invented an Improvement in Cementing-Machines, of which the following description, inconnection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

\ This invention relates tol a form of. cementing machine to be employed in cementing down the channel fiaps of boots and shoes, and more particularly the charfnel flaps of McKay sewed shoes, but which is also adapted to be employed inV applying cement in various other relations.

When the outer soles of McKay sewed shoes are channeled, previous to sewing, the channel flap is usually turned .over and laid flat with its grain side resting upon 'the outer surface of the sole. The operation of turning these flaps back by hand and cementing them in place, after the shoe is sewed, is a source of much difliculty and inconvenience; for, in addition to the time consumed in performing this operation, the flaps are often broken off, particularly if they become dry, and the workman often cuts his lingers. Moreover, it is very difficult to apply cement to the inner surface of the flap while it is lying fiat on the surface of the sole, without also applying more or less to the surface of the sole, so that stains are often caiised thereon which it is impossible to remove effectively by buliing. In addition to this diiliculty a channel flap of ordinary width is usually pressed into folds when it is turned back onto the sole about the curved portions of the shoe, as the toe, with the result that the inner surface of the flap is imperfectly cemented.

`My invention has for its principal ob'yect to produce a cementing machine of the above described character which is adapted to apply an even coatingof liquid cement to various surfaces, and particularly such surfaces as those above referred to, and which will, at the same time, work the cement thoroughly into the fiber of the leather.

Further objects of my invention are to produce a machine of the above character which is simple in -co-nstruction 'and is unlikely to become clogged with cement or to get out of order in ordinary usage; to provide a simple and effective means for feed- ,passage c4.

ing the cement regularly; to provide means for turning the. channel iiap up from the sole, so that it may be easily pressed down in place and t0 apply a coating of cement to the entire inner surface thereof without `ap-l plying it to the outer surface of the sole or iap; and to provide a means wherebv the shoe may be fed rapidly beneath/the brush while it is being cemented, without any more effort on the part of the operator than is necessary to hold the shoe against the cementing and flap-turning devices.

I accomplish these objects by' the means shown in the accompanying drawings, in which,

The cement-containing tank a may be uncovered, or provided with a suitable cover, said tank being supported upon a base b A horizontal shaft c, having a driving pulley c thereon, is journaled in the rear Wall of the tank, near its bottom, and extends therethrough to its front side into a tubular spout d, which is secured to the front side of the tank in register with an aperture therethrough, and forms a liquid tight connection therewith. Said shaft c lits as closely into the bore of the spout as possible without interfering with the free rotation thereof. Said shaft c is provided with a square screw thread c2 which extends from the bore c3 which extends from the front end Patented Nov. 5, 1912.

ico

thereof to a point within the tank, said bore being connected to the tank by a radial A nozzle e, having a longitudii lao recess f3.

l' treadle or foot lever flat on its right `of Fig. 3. A^ stop screw nal bore extending from the rear end thereof and terminating near the front end thereof,

1s telescopically mounted on spout d t-heV atter tting closely therein and yet permitting longitudinal movement ofthe nozzle thereon, and swinging movement of the nozzle about the longitudinal central line thereof, as an axis. A valve seat e is provided at the end of the bore of said nozzle, and said seat is normally held against the end of said spout byI springs it, thereby tightly closing the same, as shown in Fig. 4.

The nozzlee is provided with a radially extending socket e2, in which a cylindrical brush holder f is longitudinally and rotatably adjustable, said-holder being clamped in place by a set screwf4 and being provided with a brush f. Said brush is preferably hand side, the plane of which /side is approximatelyradial to the axis of said nozzle. `A discharge pipe g is secured inthe holder f,said pipe being con'- nected to theend of a passage f2 through the holder, and said passage f2 leadinginto a centrally arranged recess f3 in the upper end thereof. The nozzle is provided with a` radially extending passage e8 which leads from the bore thereof at a pointa short distance from seat e', communication @between saidbore and said The pipe g extends downward closely adjacent the flat side of the brush and slightly obliquely toward the front edge of the brush.

A rod z is jour aled inl lugs on the side of the tank, andl forked arm k is secured to said rod and extends on opposite sides of the nozzle e, as shown in Fig. 2, in a position to engage a shoulder or rib e4 formed on therear end of the nozzle. An arm lis also connected to the rod i, and said arm is inturn connected by link -m to a n, so that when the treadle is depressed the nozzle may be moved longitudinally on the spout to the position o is provided in a lug on the tank, and is adapted to limit the downward movementof arm Z. A shaft p is'journaled in the base b, and is adapted to be driven by a belt p from the shaft c, the shafts p and c being parallel, and the front end of the shaft eccentric longitudmally extending crank pin 3D2.v An arm e5 is formed integral with the nozzle e, and extends downwardly and rearwardly from the under side thereof, said arm having a rod z secured to the lower end thereof, the longitudinal central line of which'is perpendicular to the axis of nozzle e. A- sleeve g is slidably mounted on said rod 1", and has an ear g. at one side thereof vthrough in which it is adapted to rota-te. By this means rotationofthe shaft p will cause the nozzle@ to oscillate about the'centrallongif t axis of the nozzle,

therebyv providing being provided with an V which the crank pin p2 passes, and

tudinal line of the spout d as an axis, said means also permitting longitudinal movement of the nozzle on the spout.

A Achannel-flap turning arm or rod s is slida-bly mounted in the front end of the nozzle e, in such a position that its center line is approximately perpendicular to the and in the plane of the flat side of the brush, although t-he exact position in which it is held is not absolutely essential. The lower end of said rod is provided with a transversely `extending {laplifting and turningv lip s and the slde of said rod, above said lip, is obliquely beveled with relation. to the flat side of the brush, as shown in Figs. 5, 6, 12 and 13. The end of the rod is beveled from -the edge of the lip s next the brush, so that this portion of the lip is the lowest point of the rod. The-rod is held from turning by a screw s3 the inner end of which is held close to a longitudinally extending Hattened surface formed on the rod. A on the rod s between a lug e on the nozzle, and a collar s, -which is threaded on said rod, and said .spring normally holds said collar against a seat formed ona portion of tHe nozzle through which the rod passes.

Said collar is preferably adjusted so that the lower end of said rod is on a-level with .the face or lower end of the brush, the

collar being screwed down on the rod to raise itwhen the end of the brush becomes worn.

The operation of my device is as follows The sliaft c is rotated in such a direction that the screw c2 will act in the manner of an ordinary screw pump, or water screw and will force the cement in the tank forwardly through the .spout d at a uniform rate. When the spoutis closed, that is, when the springs z draw the seat c of the nozzle against the end of 'the spout, the. cement which is discharged into t-he chamber at the end of the shaft c 'cannot pass through passage e3, and passes back into the tank through the relief passages c3, vc* of the shaft. If the relief passages were not provided the pressure against the seat e would be so great that the nozzle would be forced away from the end `of the spout, so that the cement would pass through the passage e3 into the discharge pipe, necessitating the stopping of the shaft when it was desired to stop the iow of cement. By providing the relief passages, however, pressure against the nozzle cannot become sufficient to overcome the tension of the springs h, so that the end of the spout will betightly closed when the pressure on the treadle is relieved.

As the shaft rod will rapidly oscillate, the Darts being so arranged, that the brush and rod .will 'be swung from a point in which the fiatside of th e the brush and center line of the rod are in a ver-I tical plane through the axes of the nozzle, see the full line position of Fig. 6, to the left or rearwardly with relation to the brush, to the dotted line position of Fig. 6. The treadle being depressed, the nozzle will be forced forward to the open position shown in Fig. 3, so that the cement will be discharged freely from the tube g at the right side of the brush, and within its plane of oscillation, adjacentthe middle thereof, or between its middle and its front edge.

As previous to sewing, the channel iiap has usually been laid over flat 'on the surface of the sole, in order to turn the fiap back and cement it down over the stitches, the lip s of the turning arm or rod s is caught under the flap, as indicated in Fig. 12, and as the shoe is fed to the left said flap .will be turned by the lip of the rod into a vertical position with relation to the sole, so that it will pass between the side of the rod, and

the adjacent edge of the brush, as shown inv Figs. l2 and 13.' The end of the tube g ex tends a short distance below the edge of the l flap when the flap is heldin said vertical podirection in which" the shoe is fed,

sition, and the tube g is held in such a posi tion, or at such an inclination, that the stream of cement which is forced therefrom will be directed into the inner, or lowestportion of the channel. As the brush is mov-ed back from the vertical position to the dotted position of Fig. 6, a quantity of cement will be discharged into the channel, and as the brush is moved forward again, opposite the it will sweep the cement into a wave which will extend from the edge of the flap to the outer edge of the channel. As the end of the brush sweeps over the entire bottom of the channel, and its front or. outer edge bears against the entire flesh side of the flap, the flap being held against the brush by the rod, an even coating of cement will be applied to the bottom of the channel and fleshl side of the iiap, and superfluous cement will be carried on in front of the brush. The brush holder is made circularly adjustable and the tube g is arranged eccentrically with relation to the axis of adjustment thereof, so that the discharge end of the tube may be moved to an extent toward and away from the rod s by rotating the holder f into differ? ent positions in the socket e2. It is usually found necessary to set the brush in one position for a wide channel, and into another for a narrow channel, but'the exact positionin which the tube and brush shall be held is a matter depending on this, and various other conditions, which need not be defined.

lVhile the end of the arm, or rod s is referably normally even with `the end o the brush to permit the lip thereof to be passed under the channel iiap conveniently, this arrangement is notessential, although preferably the brush should not extend below the end of the rod. After the brush has passed into the channel'the rod will be pressed upward as shown in Fig. 12, the sole being held up closely againstthe brush and rod and also in a slightly inclined position, so that the surface of the sole will rest against the inclined end of the rod when the latter' is in a vertical position. Whenthe brush and the rod s are swung to the left from this position, 'the shoe in the same direction, see dotted position of Fig. G, then as they are swung to the right again, they will be moved out of Contact with the sole, and will not tend to move the shoe back in the other direction. But the operato-r is all the time pressing the shoe upward, so that he moves the shoe up againstthe end by the time the latter has been moved to the vertical position. The feeding movement will then .be repeated, and the shoe will thus be rapidly fed along without spe cial effort on the part of the operator. rlhe feeding of the shoe isthus materially assistedby reason of the oscillating movement of the above described parts, the particular formation of the lower end of rod s being of special importance in this connection. The object of having the side of the rod above its lip si inclined with relationto the face of the brush is so that the channel iiap will be turnedup easily as it is drawn between the rod and brush. As the flap is turned up to a. vert-ical position, all the folds or plait's will be removed, so that the entire surface' ofthe fiap will be exposed to the action of the brush.

The result of the above described operation is to apply an even coating of cement to the bottom of the channel and the entire inner side of the iap, leaving the latter so that it may be readily pressed 'down and cemented in place, without applying cement to any of the exposed surface of the sole. This operation is, moreover, performed as rapidly as the shoe can be handled.

Thearrangelnent of the central line of the rod in the plane of theiiat. side of the brush is of advantage, as it is thus difficult to hold the shoe so that the channel-flap will be lifted too far in advanceof the brush and will not be held against its side as it passes the same. This feature is of special importance when applying the cement about the toe of the shoe. The oscillating action of the flap turning arm or rod is also of special importance, as the iap is raised by a rapid succession of blows thereon by said arm, which are resisted by the inertia of the shoe. -As the shoe is pushed back by the turning arm and brush after each blow, it will be evident that Vthe fiap will be raised without special effort on the part of the operator.

they will also push or move y Inasmuch/as the end of the guard rod s, or the underside of its lip s is inclined with relation to the rod and face of the brush, it will be apparent that the face or `bottom of the slice may be held atany desired inclination With reference to the brush, the edge j and under side of the lip s providing a surface about which the shoe may be readily rocked to vary the force with which the brush is pressed against the Work and the /proportion of the Work which shall be engaged by the brush, and to meet the lvarying conditions encountered when cementing different portions of the channel.
