CEMENT-APPLYING MACHINE.

To all whom it may concern:

Be it known that I, WVILLIAM F. LAUTEN- SOHLAGER, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Gement-Applying Machines, of which the following is a specification.

My invention relates to cement applying machines, and is primarily intended as an improvement on a cement applying machine of the general character of that shown and described in Letters Patent of the United States No. 913,829, granted on my application therefor, and dated March 2, 1909.

In the present exemplification of my in vention, a machine is illustrated intended for the purpose of applying a narrow band of cement to the edges of vamps or other parts used in the manufacture of shoes or foot-wear, and the like. A large proportion of these parts are skived, that is, the edges are cut tapering in crosssection, so as to enable these taper-ed edges to be folded back upon themselves without undue increase in thickness of the part, and I have shown the action of my improved device upon a skived piece of goods.

A further object of my invention is to provide stock-feeding means and cement-applying means embracing stock-supporting means so arranged that relative pressure between said stock-supporting means and the opposing parts therefor of said cement-applying means and stock-feeding means may be exerted to insure definite feeding relation between the feeding parts of said stockfeeding means; further, to provide means whereby the extent of relative yield between said parts may be regulated, and further, to provide means whereby the resistance to said yield may be adjusted.

Objects of my invention are further to provide a cement-applying machine with feeding means, and with a cement-applying part and stock-supporting part, with means for permitting yielding between these latter parts which may take place independent of the stock-feeding means and, further, whereby these latter parts may be permitted to yield with and independently of the stockfeeding means. Further, to provide a cement applying machine in which a yielding Specification of Letters Patent.

Serial No. 480,663.

action is provided between the cement-applying part and the stock-support from a pivot whose axis is substantially parallel with the direction of feed of the stock. Further, to provide means whereby a yielding action is provided in the stock-feeding means and between the cement-applying part and its opposing stock-engaging part, the resistance to the yield in the stock-feeding means being greater than the resistance to the yield between the cement-applying part and its opposing stock-engaging part.

The invention will be further readily understood from the following description and claims, and from the drawings, in which latter:

Figure 1 is a side elevation of my improved device. Fig. 2 is a front elevation of the same, partly broken away. Fig. 3 is a vertical section of the cement-applying parts of my improved device, partly broken away, the section being taken on the line ze of Fig. 2. Fig. 4 is a plan view of the stocksupporting parts of my improved device, with the supporting bracket therefor partly broken away. Fig. 5 is an enlarged side elevation, partly broken away, and partly in section on the line z-z of Fig. 2, showing the relation between the cement-applying part and the-feed-wheel and the stocksupporting parts opposed to said cementapplying part and feed-wheel, when the same are in idle relation; and, Fig. 6 is a similar view showing the relation of these parts when a piece of stock is being fed through the machine.

1 represents the frame which is shown in the form of a column provided with an overhanging goose-neck portion 2 on which a cement-cup 3 is mounted, the cup being closed by a cover 4; held in place by a clamp 5. A cement passage 6 communicates with the interior of the cup and with a recess 7 in a cement-head 8, a valve 9 regulating or shutting off the supply of cement.

10 is a cement-supplying roller which is provided with cement-supplying recesses 11, the roller being mounted on a shaft 12 journaled in bearings 13 in the head and driven by a gear 14.

15 is a feed-wheel for the stock, and is secured to a shaft 16 shown journaled in a bearing 17 in the frame and a bearing 18 on the goose-neck. 19 is a cement-applying part, shown as a brush, secured to a sleeve 20 on which there is a gear 21, the cement applying ameter than the feed-wheel, which latter is also shown as provided with stock feeding teeth 22 about its periphery. The shaft 16 is driven in suitable manner, as by a pulley 23, and has a gear 24 secured thereto which meshes with a gear 25 secured to a shaft 26 j ournaled in a bearing 27 in the goose-neck 2 and also having a gear 28 thereon wlnch meshes with the gear 21 011 the sleeve 20, and also preferably meshes with the gear 14 on the shaft of the cement-supplying roller. The construction and arrangement of these parts is preferably such that the cementapplying brush or rotary cement appller will be rotated with its cementapplying portion which contacts the stock traveling at greater peripheral speed than the speed of feed of the stock for carrying the cement from the cementsupplying roller to the stock with a motion imitating the motion of applying the cement to the stock by hand with a brush, as more fully explained in my aforesaid application.

I have found it desirable that there shall be yield between the opposing parts of the stock-feeding device and between the cement applier and the stock-support opposed there to, and that yield between these latter parts may be effected additionally to the yield in the stock-feeding part-s, and I effect these purposes in novel manner now to be clescribed.

29 is a lever which is pivoted between trunnion screws 30 operable in threaded bearings 31 in a bracket 32 extending from the column. This lever carries a stock supporting roller 33 journaled on a pin 34 held in a bearing 35 in the lever by a set-screw 36. 37 is an adjusting screw threaded in the lever and received against the bracket 32, by means whereof the position of the roller 33 with relation to the feed-wheel may be regulated, the roller being preferably normally just out of contact with the feed-wheel. 38 is a spring which urges the stock-supporting roller 33 toward the feed-wheel 15. The tension of this spring is adjusted by its being received in a socket 39 of an adjustingscrew 40 threaded in a threaded bearing 41 of the lever 29, the end of the spring being received in a positioning-recess 42 in the bracket 32. The pressure of the feeding mechanism upon the stock is thus regulated. If desired, the stock-supporting roller 33 may be depressed for receiving the stock between the roller and feed-wheel, by means of a link 43 connecting with the lever 29 and with any suitable treadle mechanism. The lever just described may be termed a primary lever, upon which, in the present exemplification, a supplemental or secondary lever is pivoted.

part being preferably of greater di- There is a stock-support which is opposed to the cement-applying part or brush and which I have shown as yielding'with and independently of the stock support of the feeding mechanism. I provide the addi tional yield between the rotary cement applier and its opposed stock-supporting part primarily for the purpose of insuring that co-acting relation between the feeding mechanism and the stock may always be main; tained irrespective of the condition of the rotary cement-applier, and further so that there may be a resilient cushion under the rotary cement-applier capable of yielding without affecting the stock-feeding function, so that cement-applying and cement-feeding conditions may be accommodated to a nicety, and thus presenting relatively proper stock feeding and cement-feeding and applying conditions.

44 is a stock-support, which is opposed to the rotary cement-applier, and is on a lever 45 which is pivoted to the lever 29 at 46, a spring 47 urging the stock-support opposed to the rotary cement applier toward the latter with resilient pressure, which pressure however is preferably less than the pressure exerted upon the stock by the spring 38. The spring 47 is also preferably adjustable by being received in a socket 48 of an adjusting screw 49 threaded in threaded bearing 50 in the lever 29, the upper end of the spring being received in a positioning recess 51 in the lever 45.

The relative idle positions between the stock-supporting face of the stock-support 44 and the stock-supporting face of the stocksupport for the feeding-mechanism, (see Fig. 5) are preferably adjustable, and the relative positions of these faces when in operative relation (see Fig. 6) are also preferably adjustable. I accomplish the relative relations of these faces when in idle position by means of a set screw 52 adjustable in a threaded bearing in the lever 45, a lock-nut 53 being provided for the same. The screw 52 is arranged to strike a bolt 54 or other relatively stationary part of the machineframe and thus determine the elevation of the stock-support 44 with relation to the upper face of the periphery of the stock-supporting roller.

55 is a set-screw threaded in a threaded bearing in the lever 45, a lock-nut 56 being provided for the same, the set-screw 55 being adapted to strike a lug 57 on the lever 29 for determining the position of the stocksupport 44 when the stock-supporting roller depressed.

58 is a stock-gage on the lever 45 and is shown adjustable by providing a securingbolt 59 received through a slot 60 in said gage into the lever 45.

The stock-engaging face of the support 44 is preferably rounded to correspond with the rounding of the stock-engaging periphery of the roller 33, and said stock-engaging face and the stock-engaging face of the stockgage 58 are preferably abbreviated, extending forwardly, or opposite the feeding-in face of the rotary cement-applying part, and terminating adjacent the vertical plane of the rotary axis of said roller 33, that is, adjacent a straight line drawn between the axes of said roller and the rotary cementapplying part, for permitting stock with curved edges to be readily guided around and upon said gage and support.

It will be noted from Figs. 5 and 6 that the innerface of the stock-supporting roller 33 is slightly outside the inner face of the feed-wheel 15 for distancing the said inner face of the stock-supporting roller from the cement-applying brush; further that a space 61 is provided between the inner face of the stock-supporting roller and the outer face of the stock-support 44; and, further, that when the stock-support H is depressed, its outer end is distanced from the cement-applying part. This is for the purpose of preventing unintentional application of cement by the cement-applying part, to the stock-supporting roller and outer end of the stock-support 44:, as it will be understood that the outside or finished surface of the goods or stock is usually applled to the stock supporting roller and that cleaner work is permitted by preventing such unintentional cement-application. Contact between the inner edges of the brush and stock-support opposed thereto is not harmful because the extreme edge of the stock is usually bent back and thus hidden, but this may also be prevented by ad justment of the set-screw 52.

62 is a guard having a limb 63 received in front of the feed-wheel and a limb 64: received at the rear of the feed-wheel. This guard insures proper presentation of the stock into the feeding devices without danger of injury to the operator and insures release of the stock from contact with the feedwheel and rotary cement applier for pre venting the stock being carried up the rear face of the feed-wheel or rotary cement applier and between the latter and cementsupplying roller. The limb 64lpreferably is received across the circle of the periphery of the rotary cement applier.

In operation, the edge of the stockwhich it is intended to cement is placed between the feed wheel and the stocksupporting roller, the latter being momentarily depressed when desired through the medium of the link 43. The rotary cement applier is preferably of greater diameter than the feed-wheel and rotates at greater peripheral speed than the feed-wheel. The pressure of the stock-supporting roller toward the feedwheel is provided by the spring 38 acting on the lever 29. The stock-support 44, op-

posed to the rotary cement applier, is permitted to yield with relation to the feed wheel for accommodating the condition of the rotary cement applier or the cement feed. This construction permits the stock to yield under the cement-applying part for resiliently forcing the stock against the cement applying part during cement application and causes a definite speed of feed of the stock so that relatively greater peripheral movement of the rotary cement applier than the speed of feed of the stock may be maintained. The pressure between the stockfeeding means upon the stock is greater than the pressure between the cement applying means upon the stock, so that definite rate of feed of the stock may be maintained while resilient pressure between the cementapplying means is provided.

In the construction shown in the drawings with special reference to Fig. 5, I have placed the axis for the pivot of the supplemental lever and the upper face of the periphery of the stock-supporting roller equal distances from a right line drawn between the axis of the pivot of the primary lever and the axis of the stock-supporting roller 33, the stock-support opposed to the rotary cement applier being depressed below a right line drawn between the axis of the pivot of the supplemental lever and the upper face of the periphery of said supporting roll when the parts are in idle relation. Upon the insertion of the stock between the feed-wheel and its opposed stock-supporting roller, (see Fig. 6) the primary lever is depressed at its outer end to the extent of the thickness of the stock, which depresses the pivot of the secondary lever to proportionally less extent and permits raising of the stock-support thereon with relation to the stock-supporting roller, preferably so that the adjacent supporting faces of said stocksupports extend in substantially a common plane when in operative relation. The stock-supporting roller is held toward the feed-wheel with resilient pressure and the stocksupport opposed to the cement-applying part is also held toward the cement-applying part with resilient pressure, the resilient pressure of the former however being preferably greater than the resilient pressure of the latter to insure that the stock may be fed at definite rate, so that the difierence of speed of travel between the cementapplying periphery of the rotary cement applier and the stock may be maintained, and for providing a resilient pressure against the face of the stock opposed to the face just receiving the cement. The position of the secondary lever is also preferably adjustable with relation to the primary lever for adjusting the normal relation between the cement applying part and its opposing stock-support, while the position of the pricomblnatlon of mary lever is preferably adjustable for regulating the distance between the opposing parts of the stock-feeding mechanism.

It is obvious that changes in construction of my improved device may be made without departing from the spirit of my invention.
