To aZL'whom it may concern:

Be it knownthat I, Hanna: I. Tunnewou'rl-I, a citizen of the United States, residing at Swampscott, in the county of Essex and State of Massachusetts, have invented an Improvement in Rotary Cemcnters, of which the following description, in conned t'ion with the accon'ipanying drawings, 1s a specification, like letters on the drawings representing like parts. 7

My present invention is a cementing machine.particularly intended for the use of shoe :factories and more especially for cementing such ieces as can be advantage- 5 :ously. cemented by. being folded over on then'iselves. For example, a shoe upper has syi'nlnetrieal curves on its opposite sides and the present way of cementingthe edge (when cemented by machine) is to hold the vork up to the cementing wheel and dexteronsly turn the work so that the cementing wheel .will follow around the curved edge in such a manner as to deliver the desired narrow strip or layer of cement. inasmuch =-as the-curve is svnnnetrical on its opposite sides I propose to fold the work over on itself so that the two symmetrical curves will come. in accurate alincmentwith each other, andthen apply the content simultaneously to the opposite edges thus folded over. My present invention is a machine for accomplishing this result. By this means the cen'ienting is accomplished in half the time previously required and-much less dexterity required on the part of the operator'inasmuch as the application of the cement does notrreqnire-that the workshall be turned to any great extent, I. (2., the direction of move meat-is almost in a straight line as distinguish'ed from being in a long-U-shaped curve as previously.

Iha'v'e given theabore illustration of cemcuting a shoe upper, to makeclear oneof the prineipal-advantages of a. main feature of my invention,

In carryingout the invention, I prefer ably provide, in connection with an upper cementing device and a lower cementing device, means for rendering one of these cementing devices inoperative at will or in other-words my invention includes the provision -of means for converting the nachinc into a one-side eementer or a two-side ceiuenter, so that the machine can be used for ---cemcnting on one side of the work only,

ROTARY CEMEN'IER.

Specification of Letters I atent.

Application filed March 31, 1908. Serial No. 424,386.

Patented Mar. 7,1911.

' whenever the nature of the work orthe preference of the user demands this, or it can be used for cementing on both sides of the work.

My invention also includes means for rendering it impossible for the machine to leak .or .drip cement upon the work, whatever cement may leak down being automatic-all sucked up and returned to the cement:- tank by the regular operation of the machine. The mounting of the cement pot or tank is also novel. means being provided whereby it centers itself so that it putin position at all it cannot fail of being correctly placed. The regulation of the cement. is made more delicate and accurate than heretofore by means of blocks or gates preferably of wood.

further importantfeature or sub-coin--- bination'herein claimed relates to the provision of cushioning means or spring-giving adjustment for the opposite cement apply-' ing devices whereby the same effect onthe work is produced as heretofore with a cement applying roll made of resilient rubberlike material. and yet my roll or cement ap plying device is composed of metal or other unyielding substance.

The constructional details of my invention and further advantages thereof will be pointed outin the course of the following description. reference being had to the accompanying d 'awings, in which I have shown a preferred embodiment of the invention.

In the drawings, Figure 1 is a view of the machine in side elevation, parts being broken away and sectioned for clearness of illustra tion; Fig. 2 is a view thereof in end elevation, parts being similarly broken out and sectioned; Fig. 3 is a plan view of one of the felts; Fig.4 is, a similar view of ashoe upper-in the position heretofore necessary for it to occupy when being cemented; and 1 Fig. is aplanview ofthe same upper folded over on itself in proper position for being cemented by my machine.

"While .my invention, in its broader aspects, is applicable to a wide range ofce mentingi, machines and appliances, it is more part-icularlyadapted to a rotary eementer, and accordingly for convenience of illustrw Mon and dcscriptioml'have herein shown it applied to .the type of eementer disclosed in my Patent No. 878,959 dated Feb. 11, 1908.,

Referring to. the drawings, I provide a frame comprising an overhanging arm 1,

upright or standard 2, and base 3 carrying an upper shaft 4 journaled beneath the arm 1, and a lower shaft 5 journaled at 6, 7 in a hanger or carrier 8 pivoted at 9 to the standard 2. The shafts 4, 5, are provided at their outer or front ends with cement delivering wheels 10, 11, having peripheral cement carry 1ng pockets 12, 13, and at their rear ends wlth intermeshing driving gears 14, 15, driven in any suitable manner, As herein shown .the shaft 4 has fast thereon a bevel gear 16 meshing with a driving gear 17 fast on a vertical shaft 18 provided with a wormwheel 19 engaged by'a worm 20 on a shaft 21 provided with a spring-held clutch -22 of, any suitable kind' and operated in usual manner by a foot lever (not shown). The

cementing wheels 10, 11,,are normally, held pressed tightly toward eachother by suitable means, which as herein shown, consists of a spring 23 engaging at its rear end .a boss 24 on the standard 2 and at its forward end held by a swiveled collar 25 adjustably supported on a hand adjusted bolt 26 mounted at 27 in the carrier 8. The cement wheels may be moved temporarily apart, and are at all times under the control of the operator by means ofa strap 28 connected with a treadle (not shown) and hook 29 securedin the carrier 8, an adjustable stop 30 being mounted adjacent thereto in the base 3 and provided with a thumb nut 31. for limiting with extreme nicety the approach of one cement wheel toward or' against the other.

' The cement is delivered to the cement wheels from'any suitable source, that herein diate trough or hollow, preferably rectan-' gular, centering cavity 37. Because of this constructiom'the tank tends automatically to center itself and bring itself into exactly correct position over the cement wheel simply by the act of placing it more or less carelessly in position. As the neck 34 is placed over the arm 1 it slides naturally into the hollow or centering cavity 37 and is directed by the latter into correct positiom'so that the tank is thereby brought around into properalinement with the wheel 10 and with the adjacent re 'ulating pad, blocks, etc. From a'practica standpointthis feature of my inventionhas provedof decided value,

it being remembered that cement is difficult to handle, is liable to smear and stick everything that it comes in contact with, and not easily cleaned away. The delivery opening 35 is closed by any suitable valve mecha-' nism, a rotary valve 38 being herein shown, operated by a handle 39 whereby it may be opened or closed by a quarter rotation in one directionor the opposite. The bottom of the neck 34 is planed fiat and the centering cavity 37 is provided withinwardl projecting flanges 4O separated by a sot or opening 41 for the passage of the top edge of the wheel 10, said flanges 40 serving to support in proper horizontal fiat position a pad 42 preferably of felt, and adjacent clamping blocks 43 adjusted by screws 44. This felt pad, etc.,. construction constitutes an important feature of my invention, as it provides a construction which not only prevents leaks readily and is capable of quick renewal, easily refitted, etc., but is inexpensive, not liable to get out of order, is neat and normally out of sight. The felt padis cut out centrally and provided with opposite beveled ends 46. The blocks 43 bear against the felt pad lengthwise and serve to crowd the latter gently forward on all sides whenever desired, so as to engage the wheel 10 exactly as required according to the consistency or kind of ceme'ntifused. At the front end of the delivery means just below the felt I provide a small block of wood 47,

which constitutes a gate and bears against the pocket-containing edge of the wheel 10, being delicately adjusted by a thumb nut 48 provided with a shoulder. 49 engaging a notch 50 in the under side of the block 47 at its outer end. I have found that a small piece of wood directly adjacent the felt pad will produce an accuracy and nicety of cement delivery which it is impossible to secure by the feltalone. Instead of wood, fiber of suitable alloy or aluminum may be employed, At the same side or edge of the wheel 10 I provide a depending finger guard 51 which extends downwardly as close as I possible to the bight ofpthe wheels 10 and 11 without interfering with the work and prevents the possibility of the operators fingersbeingcaught by the wheel 10, while yet permitting the operator to feed into position small fine work'which 'couldnot otherwise be done with safety.

At the rear or up going side of the wheel 10 I have provided a feature which in practice has proved 'very' useful. One of the v greatest objections to power cementer that, at unexpected moments, they-per nt more or less cement to drop on th'ewo'rk. The present type of;.machine'orig1nally proved no exception to this rule, and I found that mere scrapers would not cure the difficulty as the cement would flow downward near the center at .a slight distance from the axis of the wheel until it had col.- lected sufficiently to drip onto the work, but all this is doneaway with simply by em- "Qbrac-ing the rear edge of the wheel by'opposite wings 5590f a cement removing device which preferably extend obliquely down-' ward far enough to engage the sides of the wheel at the region where the cement has been accustomed to collect. asflabove explained. The lower edges of these wings 52 preferably fiare slightly as indicated at 53, the upper portions of the wings practi eally engaging'the sides of the, wheel out, wardly to its periphery. As the wheel'rotates the cement which tends to collect in the pathv of the point of the cement removing device, is caught by the slightly flar ing lower edge of the wings-'32 and is gradually worked outwardly'by the wings as the wheel lO continnes to rotate, until finally the cement reaches the periphery of the wheel ina globule which is held in by .a flaring guard or lip 54, with the result that the globule. of cement gradually works over, against the periphery of the wheel and is carriedgradually upward until suddenly it sucked up, as it were, by the pockets or ..cement inthe pockets at the periphery of the wheel and then at once. disappears up into the pocket. Preferably the part 55 of the guard or end portion of the cement remover adjacent the periphery of the wheel extends obliquely toward the periphery so as to make the throat or passageway for the cement. gradually smaller toward the direction of movement of the wheel 10. In practiee this cement remover counteracts all. tendency of the machine to drip cement, and keeps the work invariably clean.

As already stated, one of the leading and most important features of novelty of my present invention consists in 'n'oviding means for cementing the work at will either on one or on both sides, and accordingly, in the preferred embodiment of my invention hereinshown, 1 provide a duct from the cement tank 32 for delivering cement tothe "lower cement wheel 11, said duet being herein shownas a pipe secured by a clamp 57, anelbow 58, pipe 59. Ile. :ible tube (30, pipe (11, tubular elbow and cast1ng (i2,-the

- latterbeing provided with a shut oil valve G3 operated by a handle 64;,said elbow 62 opening into a casting (35 at (36, which 1s pro- "vided. with-a-c'ement chamber 67' having: an

[opening 68 at'its top. Above the castingfii' is a casting-69 on whose internal ledge 70 I mount a ,felt pad 71 surromuled by movable clamping bars orplates 72, 73,,arnd held 111 place by a plate H by screws 75, the clamping plate being'm-tuatedby set screws 70., and the whole held together by thumb screws 77 at the opposite ends. The wheel 11; runs .in a slot 78 of the felt pad, and a wooden block 79 bears against. the 113' oin" side of the cellular cement wheel 11 the sa me as in the case of the block -17 already described. The block 79 is actuated by a thumb screw 80 whose rib 81 entersa groove 82 in said block. By this means" the utmost nicety of cement delivery or regulation is bad for the lower side of the work at. wheel 11 as for the upper side of the work at wheel 10. For "some kinds of work it is desirable to cement. the upper side only of the stock, and accordingly, in such case, thexcontrolling valve 3 is closed and the chamber (37 is drained, being provided [or this purpose. with a removable plug or closing device'83. And in tl1is.case the wooden cleaner or regulator block 79 is moved back out of engagement. with the wheel 1].

In use, let it be supposed that it. is desired to apply cement by both'the upper and the under cement wheels on a vamp folded along" its middle as shown in the drawings. both valves 38 and G3 are, opened, and the felt pads and adjusting blocks of wood or equivalent material are carefully adjusted so as to cause exactly the rightamount of cement'to be delivered according to the requiremcnts of the guru piece of work, and

then the f'oot lever is operated so as to throw the driving clutch 22'- mto operation, whicl1 causes the wheels 10' a11d 11 to feed thework .ifomvard, guided by a workre s't Sjnstfat' the p rear of the meeting edges of the cement wheels. ,The result is that 'the work is quickly and neatly cemented with a thin narrow stripof cement exactly as required, and without danger of getting any cement elsewhere on the work. In case the operator should, through carelessness, permit the work'to roll up on the top roll or otherwise clog the machine, he letsup. on the clutch 22,, which 'at once stops the machine, and then instantly depresses'thc treadle chain 28-, thereby separating the wheels 10 andll sufliciently to permit the removal of the tangled piece of work. "The head transmitter arrangement. of the worm and w'orm wheel give instantstopping and starting movement so thatthe cement wheels can run an exceedingly short-distance if desired. The spring adjustment i -----26 and the pivoting of the hanger or carrier 8 affords a yielding construction which permits .the ccment wheels or' whatever cementing devices are used to give acushion ell'cct. The result is thatthis takes the place of the usual rubber roll, which has heretofore been consideredmore or less essentialfor shoe work, especially for cenldnting uppers and small work. Rubber or composition" rolls, esspecially when used on small work such as j many of the small parts of shoes, wear out bottom wheel is'similarly adjusted.

to provide a durable substitute for the previous rubber roll construction. The adjust merit pfithe spring 23 permits the pressure of the two cement wheels to be varied as desired, and by adjusting the thumb nut 31 the normal proximity of the wheels and 11 may be regulated with great nicety. If 1t is not desired to cement both sides of a plece, as in the example previously given,

lo the valve 63 is closed, the stop 83 is opened,

permitting the cement to drain elf from the lower cement wheel 11, and the wheel is run against the. block 79 and the adjacent felt pads, -et c., until it is entirely clean, where 15 upon the block 79 is moved back out of the way, and thereafter the machine is run with one cement delivery wheel only delivering cen'ient. If at any time adili'erent kind of cement is tobe used, it is unnecessary to empty the cement pot, clean it out, etc., as

heretofore, but instead thereof the valve 38 is simply closed and the thumb nuts 36 are caused to disengage the pot 32, which is then lifted from 'the machine and another similar pot containing the desired cement is put in place. It's neck 34; automaticallycenters the pot and gets it into-exactly the right position with the flat bottom edges thereof in accurate engagement with the felt pad 42 all around the mouth 35, the pot being clamped and its mouth brought down with exactly the right pressure by turning up the clampingnuts 36. The wings 52 of the remover cause all the surplus cement to be car- 35 ried up from the 'sides of the wheel 10 and back into the pot, while the finger guard 51 enables the operator to place even the smallest and most delicate work accurately between the feed wheels 10-and 11. If more cement is desired, the block 47-is moved back slightly, and if less cement is desired it is moved forward. The metal bars 43 are moved inwardly by their set screws 4.4 as the felt wears or needs adjustment. then 45 the machine is used as a double cementer,

the corresponding mechanism' adjacent the One of chief aims has been to provide a machine capable of handling work not only quickly but so as to deliver the cement ing. line with precision and neatness, and at the same time to use a minimum quantity of cement. i
