CEMENT-APPLYING MACHINE.

Specification of Letters Patent.

Application filed May 7, 1910. Serial No. 560,018.

To all whom it may concern:

Be it known that I, WILLIAM F. LAUTEN- SCHLAGEE, 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 Cement-Applying Machines, of which the following is a specification.

My invention relates to cement applying machines, and is applicable for applying opposed strips of cement, preferably to the edges of articles, such as vamps or .other parts of foot wear, or other articles, '1n the manufacture of the same.

The parts to be cemented are often in duplicate, or are rights and lefts, or are so shaped that they may be folded or placed face to face, when the edges of the same will be coincident and of the same contour.

lVhen so arranged the finished sides of the pieces will face each other, and the un-v nished sides, to which the cement is applied, will be outside faces.

It is the object of my invention to provide novel means whereby the strips of cement may be applied to both of the unfinished surfaces which are on the outside of the mated or pair of parts, applying both strips of cement at the same time, thus providing economy of manufacture.

My invention consists in providing a cement applying machine having opposed cement-applying means acting simultaneously upon the stock; further'in providing opposed feeding means and op osed cementapplying means acting side y side upon the stock; further in providing rotary cement-applying brushes which are arranged to extend into each others circles of rotation when in idle relation and arranged to receive the stock between them; further in providing rotary cement-appliers located opposite each other and feeding means at the side of said rotary cement-appliers so arranged that the feeding means locate the position of the stock at the side of the rotary cement-appliers and the rotary cement-appliers act upon each other as cushions; and, further, in providing novel means in a cement applying machine whereby the stock is stripped from the cement-applying means.

The invention will be further readily understood from the following description and plaims, and from the drawings, 1n which atter:

Figure 1V is a front elevation of my imroved device, partly broken away. Fig. 2 1s a rear elevation of the same, partly broken away. Fig. 3 is an end elevation of the same, partly broken away. Fig. 4 is a vertical section of my improved device, partly broken away, taken in the axial planes of the feed-shafts, on the line 2-2 of Fig. 3. Fig. 5 is a cross-section of the same on the line y-q/ of Fig. 1. Fig. 6 is a crosssection of the same on theV line -.r of Fig. 1. Fig. 7 is an end elevation, with parts partly broken away for better illustration, showing the action of the opposed brushes upon the stock. Fig. 8 `is an axial section of the same taken on a line corresponding to the line yw-w of Fig. 7. Fig. 9 is a front elevation of my improved device, partly broken away, showing the supplemental frame in retracted position. Fig. 10 is a cross-section of the same on the line yv--fv ofFi .-9; and, Fig. 11 is a side elevation of the arrel of the rotary brush.

1 represents the frame which in the form shown comprises a column 2, having a gooseneck extension 3 provided with a hanger 4.

5 is an operating shaft. This shaft may be driven by a pulley 6 or other suitable means. It is also arranged to act as a feedshaft in manner hereinafter explained. The operating shaft has a bearing 7 in the column and a bearing 8 in the hanger. It has a gear 9 secured .thereto which meshes with a Vgear 10 on a shaft 11 journaled in a bearing 12 in the hanger, the latter shaft also having thereon a gear 13 which meshes with a gear 14 on a sleeve 15 rotatable about vthe operatin shaft. .f

A fee -wheel 16 is secured to the operating shaft so as to rotate therewith, as in the direction of the arrow a anda rotary cement-applier 17 is secured to the sleeve so as to rotate with the sleeve, preferably in the same direction as the direction of rotation of the feed wheel. The train of gearing 9 10 13 14 is preferably so proportioned. and arranged as to rotate the rotary cement-applier 17 with greater peripheral speed than the peripheral speed of the feed-wheel 16, for purposes hereinafter explained.

18 is a rotary cement-supplying roller secured to a shaft 19 )ournaled in bearings 20 21 on a cement-supplying head `22. The roller preferably rotates in the direction of the arrow b. The shaft 19 has a gear 23 Patented May 25, 1915.

thereon which meshes with the gear 13. The head 22 is rigid with the frame, as by being screwed to the threaded end of a shank lhavy ing a cement-conduit therein, for clamping the parts upon a bearing 24 on the frame. The-cement-conduit 25 is continued in the head and communicates with a cement-pot 26 in which a suppl of cement s contained, the lower end of t e pot having a removable cement-sieve 27 therein, which is spaced from the bottom of the pot, the pot being arranged to be closed by a cover 28 4 suitably secured in place. There isa cementvalve 29 in the cement-conduit in the head for regulating or shutting off the supply of cement from the pot 26.

31 is a movable frame shown as a swinging housing pivoted on trunnion-screws 32 to the VVmain frame.

34 journaled therein. This feed-shaft has thereon a gear 35v which is meshed by a gear 36 secured to vthe operating shaft. In its preferred form the pivotal axes of the trunnion-screws 32 are in vertical plane with the outer ends of the meshing teeth of the gears 35 36 and in horizontal plane with the pitch lines of said teeth at their meeting points, (see Figs. 1, 9 and 10), so that, when the swinging frame is moved on its pivots the gears are maintained in full mesh with each other at their outer ends, While the relative movement between the gears at their inner ends is a receding movement for preventing binding of any parts, the construction being j such as to cause only slight variation in meshing relation between said gears during `movement of said movable frame, the slight variation taking placel being a relieving variation. The movable framemay have a clip 37 secured thereto for limiting movement of the gear 35 and feed-shaft 34 toward the gear 36 and the feed shaft 5.

There is a gear 30 on the feed-shaft 34 which meshes with a gear 38 secured to a shaft 39 journaled in a bearing 40 on the movable frame, the said shaft having a further gear 41 thereon which meshes with a gear 42 on a sleeve 43 journaled about the eed-shalft 34, the said sleeve having a rotary cement-applier 44 suitably removably secured thereto, as by a set-screw 45. The said i shaft has a feed-wheel 46 secured thereto,

which preferably'rotates in the direction of the arrow c, the rotary cement-applier 44 rotating in similar direction.

The train of gearing 30 38 41 42 is preferably so arranged as to cause the rotar cement-applier 44 to rotate with a erip eral speed greater than the periphera speed of said feed-wheel 46. Thefparts are preferably so arranged that the rotar cement-appliers 17 44 and the feed-whee s 16 46 will rotate in opposite directions as indicated by the arrows, and be opposed to each other This movable frame comprises a bearing 33 having a feed-shaft for the purpose of simultaneously acting opposedly on the opposite sides of the stock, shown at 47, fed between the same, preferably in the direction of the arrow d, constituting the machine of a duplex-applying machine, the term duplex indicating that the cement application takes place upon both of the exposed sides of the stock during the same operation.

51 is a cement-supplying roller secured to a shaft 52 journaled in bearings 53 54 of a cement-supplying head 55 on the movable frame. (See Figs. 1, 2 and 4.) The shaft 52 has a gear 56 thereon which meshes with the `gear 41, causing the cement-roller 51 to rotate in the direction of the arrow e. (See 3.) A cement-conduit 57 communicates with the cement-supplying headv 55, a suitable valve 58 regulating or shutting off the supply of cement to said head:

There is a cement-pot 59 communicatin with the conduit, which may be provided with a removable cement-sieve 60 and be provided with a cover 61 suitably secured thereto.

The upper portion of the cement-conduit 57 and the cement-pot 59 may be a separable portion of the movable frame, held in place by the screws 62 and provided with an opening 63 to accommodate the rear trunnion-screw 32, upon which the movable frame is pivoted and the cement-supplying head and lower portion of the cement-conduit may be a separable part of the movable frame held in place by screws 64, (see Figs. 1 and 9) the upper and lower portions of the cement conduit being adjustably connected by the ri ht and left hand nipple 65. The movable rame is substantially balanced by mounting th@ cement-pot partially at one side of the vertical plane of the pivotal axes of the movable frame while the cement-applier 44 and the head 55 therefor are mounted at the other side of said vertical plane, and by the provision of a spring 66 be tween the main and movable frames.

The movable frame with the rotary cement-applier 44, the feed-wheel 46, cementsupplying roller 51, cement-supplying head 55, cement-conduit 57 and cement-pot 59, oscillate together upon the -pivotal axes of the movable frame for causing reciprocation between the rotary cement-appliers 17 44 and theY feed-wheels 16 46, there being yielding movement between these latter parts when the stock is fed between them. This yielding movement is assisted preferably by f the movable frame, held in adjustedpositions by a am-nut 7 2, and arranged to strike the end o a screw 7 3 on the main frame. (See Figs. 2 and 3).

I prefer to locate the rotary cement-appliers respectively adjacent to the feedwheels 1.6 46, the said respective rotary cement-appliers and feed-wheels having common rotary axes. Iprefer further to provide take-offs for the stock between theJOtary cement-appliers and the feed-wheels which serve the purpose of releasing the stock from the rotary cement-appliers, 1t being understood that the cement applied by my im;- roved device is usually a viscous substance. 76 77 represent the stock take-oils and are shown as plates respectively received loosely between the rotary cement-applier 17 `and feed-wheel 16 and between the rotary cement-applier 44 and feed-wheel 46.

The outer edges of these take-oils, atthe stock-contacting portions ofthe feed-wheels, are within` the longitudinal projections of the peripheries of said feed-wheels respectively. At the feed-out sides of the said feed-wheels however, that is, the sides thereof at which the stock leaves the feed-wheels, these take-oils are provided with outwardly projecting portions 78 79 which project outside the longitudinal projections o f the respective feed-wheels, and are shown as eccentric portions, eccentric to the circles of the respective feed-wheels and rotary cement-appliers. These take-offs preferably terminate in tails 80 81 received across the cement-supplying rollers 18 51 respectively serve as handles for preventing contact of the stock with said cement supplying rollers. These tails also for manually swinging the take-offs.

The stock as it leaves either rotary cementapplier has a tendency to adhere thereto, but contacting the take-olf edge of the takeoH, it is held away from the rotary cementapplier, the stock being thereby prevented from following the rotary cement-applier in its movement, the danger of having the stock carried around the rotary cement-applier or into contact with the cement-supplying roller being thereby avoided.

The construction and arrangement of the stock take-oil also permits the stock take-oil' to be located closely adjacent to and between the rotary cement-applier and the feedwheel, thereby having the further advantage of separating the rotary cement-applier from the feed-wheel for aiding in avoiding application of cement to the feed-wheel and separating the .rotarycement-applier and feed-wheel by a normally stationary plate for preventing relative influence between the rotary cement-applier and feed-wheel tending to disarrange the parts by reason of their relatively different speeds.

In the form shown the take-oil' plates are respectively provided with bearing flanges 82 83 about the respective feed-wheel shafts 5 34 between the respective shoulders 84 85 on said shafts, against which the feed-wheels are respectively received, and the outer ends of the sleeves which support the rotary cement-appliers. The rotations of the feedwheels and cement-appliers normally cause the tails of the take-olf plates to respectively contact the cement-supplying heads.

The stock-contacting points of the peripheries of the res ective feed-wheels are normally closely adJacent to each other, as shown in Fig. 3, and the rotary cement appliers are of greater diameter than the diameters of the respective feed-wheels. The peri heries of the rotary cement-appliers pre erably intersect each other when in idle relation, as indicated in Figs. 3, 4 and 5.

' The ends of the bristles of the respective opposed rotary cement-applying brushes extendpast each other at the points of closest ap roach between said rotary brushes.

en now, stock is fed between the feedwheels, these are separated by the stock, the feed-wheels,` however, exerting continuing feeding pressure on the stock, but they definitely locate the stock between the rotary cement-appliers by contact with the stock adjacent its edge." These latter, being of greater diameter than the feed-wheels, press with yielding pressure upon the respective exposed sides of the stock, thereby acting as cushions for each other with the effect of permittin the rotary cement-appliers to work or orce the cement into the pores or between the fibers of the stock, the edges of the stock yielding more or less toward one side or the other, depending on the relative conditions of the rotary cement-appliers.

The feed-wheels act with greater pressure upon the stock than the bristles of the rotary brushes, for providing definite feeding relation of slower speed than the peripheral speed of'the rotary brushes, the rotary brushes acting opposedly upon the outer faces of the stock with a wiping action as more clearl shown in Figs. 7 and 8.

It is desirable that there shall be a free flow of cement during operation of the machine, but that the flow shall cease when operation ceases so as not to waste the cement or permit the cementfsupplying heads to leale, and also that surplus cement shall be directed back into the cement-supplying heads. For accomplishing these ends, I provide the periphery of each of the cement-supplying rollers with cementsupplying recesses'y 86 which form pockets (see Figs. 5, 7 and 8) into which the bristles of the brushes are flexed for wiping the cement therefrom and carrying the cement to the stock with a peripheries of the brushes moving faster than the stock.v

brushing action, they The formation of the recesses forms ribs 87 in the periphery of the cement-supplying roller, which separate the pockets. For forming a continuous cement-supply to the brushes, grooves 88 are provided crosswise of these ribs which connect with the adjacent pockets. The pockets preferably gradaually decrease in cross-sectional area towar their lateral ends, and the grooves also preferably decrease in cross-sectional area toward the lateral ends of the ribs, as indi,- cated in Fig. 8.

The purpose of this construction is to provide* the greatest supply of cement adjacent the middle of the width of cement application, this supply decreasing toward the edges of cement application. The brushes in applying the cement will tend to spread the cement under this arrangement throughout the width o`f cement application substantially even, While at the same time excess of cement at the edges of cement application and Waste of material will be avoided.

The respective cement-supplying heads have cement-supplying reservoirs 91 92 therein. The heads, at the reservoirs, are of similar construction, the reservoir of the upper head however being above the cementsupplying roller` and the reservoir for the lower head being below the cement-supplying roller. I shall describe the upper reservoir and adjacent parts, the lower `reservoir and adjacent parts being of similar construction and reference thereto being made Y by similar reference numerals preceded by the numeral 1. Thus the head 22 has cheeks 93 94 which contact the periphery of the cement-supplying roller 18 at the ends of the recesses 86 therein. 95 is a cement-wiping lip on the head which extends across the recesses 86 and is closely adjacent to the periphery of the roller for causing the proper iilling of the recesses 86 and grooves 88, the

cheeks preventing spreading of the cement in said head on the periphery of the roller laterally beyond said recesses and grooves, for supplymg the cement within proper range to the rotary cement-appher. he head is also provided with a cement-receiving mouth 96 opposite said lip, into which the surplus cement on the roller 1s recelved for returning the same to the reservoir.

101 102 are guards secured to the respective heads and respectively have lingers 103 Y 104 received about the feed-in edges of the feed-wheels for aiding in directing the stock between the feed-wheels and rotecting the operator from contact with e feedwheels.

105 is a cement-wi ing finger for the feedwheel 16. It exten s across the outer -face of the feed-wheel toward the cement-sup-y plying roller 18, preferably contacting the eriphery of said roller, and the outer gace of said roller for keeping the feedingtorearo the bristles of f ing the cement there may be thereon into contact with the cement-supplying roller which feeds it back into the reservoir." This cement-wifpina finger is referably located a right line awn between the rotary axeis of th feed-wlel 116; and cement-supp yin ro er 18. ee n igs. 1, 3, 5 and 9.) 'lghe finger has a shank 106 which s ad'ustably received in an aperture in a lug 10 on the guard 101 and held in place by a thumb-screw 108. Theguard also has thereon a cement-wiping finger 109 arranged to contact the flange 11G-of theV rotary cement-appler 17 for -directing any cement there may be onl the outer face of said flange toward the bristles of the brush.

111 is a cement-wiping tinger for the feedwheel 46, the end of the linger being presented to the cement-supplying roller 51.

(See Figs. 1, 3, 5 and 9.) This finger wipes the outer face of the feed-wheel 46 of any cement there may thereon toward the roller 51, which conveys the wiped cement back into the reservoir 92. The said finger is preferably located to rear of a right line drawn between the rotary axes of the feedwheel 46 and the cement-supplying roller 51. It has a shank 112 adjustably received in an aperture in a lug 113 on the guard 102 and held in place by a thumb-screw 114. The guard 102 also has a cement-wiping linger 115 for the rotary cement-appher 44. It wipes the face Vof the flange 116 of the lower rotary brush and directs any cement there magY be thereon toward thebristles thereof.

leanliness of cement application is provided by these means. Ready access to the reservoir 91 is provided by a threaded plug 117- and ready access to the reservoir 92 is provided by a threaded plug 118, the threaded plugs screwing into the walls of the respective reservoirs.

121 is a stock-gage which is small in crosssection and is arranged to be received between the peripheral' edges of the anges 110 and may be laced closely adjacent to e `brushes adjacent the points of nearest approach between the latter for enabling the strip of cement to be applied close to the edge of the stock and enabling the stock to be readily shifted for guiding edges of markedly irregular shapes across the said The gage is adjustable toward an ro the rotary cementappliers, as by being provided with a slotl me for forc- Figs. 9 and 10.) The separating lever may be thrown back out of the way by swinging the same about its pivotal connection with the operating shaft 5 through the opening below the goose-neck 3 for resting upon a lug 128 on the cement-conduit for the movable frame.

I prefer to construct the cement-a plying brushes respectively by providing a ristlessupporting barrel 131 having a bearing 132j which fits the driving-sleeve therefor. The barrel has a bore 133 of greater diameter than the bore of the bearing 132. The bristles are gathered in tufts and secured in apertures 134 preferably by means of Wires 135 which are received into said apertures from the wall of the Ybore 133, the eater diameter of the bore 133 accommodating the stretches of wire between the apertures. These apertures are arranged in rows around the barrel 131 and preferably extend radially thereof. The apertures of adjacent rows are preferably arranged in advance of each other, so that the apertures of adjacent rows will not registery side' by side. At one end of the barrel, the flange (see the fianges 110) is located, adjacent to which there is arow of bristletufts. Next to this row of bristle-tufts a plate-collar 136 is received about the `barrel 131, then follow other alternate rows of bristle-tufts and plate-collars, the spaces between the collars forming annular channels in which the respective rows of the bristles are located, the plates preventing undue lateral iexing of the bristles and causing the bristles to bend in channels which extend around the barrel, thereby holding the bristles of the rotary brush un to their work` and aiding in stiffening the same so that the bristles may be caused to rmly rub the vcement between the fibers or into the pores of the stock' being cemented.

The separation of the annular rows cf bristles by the washers and the arrangement of the tufts of bristles in unmating relation side bv side also permits the lbrush to receive and deliver a maximum amount of cement, the construction further holding the respective bristle-tufts within the prescribed limits.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:
