CEMENTING-MACHINE.

Specification of Letters Patent. Patented July 1113, T915.

Application filed March 14, 191.0. Serial No. fi l-9,188.

T 0 all whom it may concern:

Be it known that l, Gannon J. JULIAN, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain limprovements in Cementing-Machines, of

which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for applying adhesive material to stock and is herein set forth as embodied in a machine for applying cement to the soles of boots and shoes.

It is common in the manufacture of boots and shoes to skive the edges of the soles particularly at the shank portion. This results in a sole the thickness of which is not uniform so that when such a sole is run through a cementing machine of the ordinary type only the surface of the thicker portion of the sole is properly coated.

Accordingly one feature of this invention consists in the provision in a machine for applying cement to stock of which the surface to be cemented has relatively 'high and low portions, of means for forcing the high and low portions of said surface into a common plane whereby all portions of said surface may be evenly coated. Any convenient mean may be made use of, and in the illustrated embodiment there is provided a cement applying roll and a presenting roll, the latter comprisin independently yieldable sections, the springs by which said sections are supported being of sufiicient strength to force the thinner portions of the sole toward the applying roll so that all portions of the face of the sole to which cement is to be applied lie approximately in the same plane, thus insuring an even coating of cement irrespective of variations in thickness of the sole. Preferably this roll is bodily movable against the force ofa resilient member so as to permit the roll to yield to accommodate soles of different thickness, the yielding sections taking care of the unevenness that may exist in any given sole.

It is essential that no considerable amount of cement be permitted to reach the sectional roll since otherwise the sections would soon become gummed together and the function of said roll thereby impaired.

Accordingly another feature of this invention consists in a construction of parts whereby cement is prevented from being applied to the sectional presenting roll. In the illustrated embodiment a cement applying roll and a stock presenting roll are provided, said presenting roll comprising yielding sections as indicated above and in order to prevent cement from being transferred from the applying to the presenting roll. the applying roll is formed on its periphery with ribs which are preferably V-shaped, and the cement is supplied to said roll by a conduit having a nozzle, said nozzle comprising a scraper or spreader to confine the cement on the exposed surface of the roll to the spaces between said ribs and a dam yieldable in the direction of rotation of the roll to permit any surplus cement to be carried back into the conduit. The ends of the roll are also beveled and cooperate with obliquely arranged scrapers to direct the ce-- ment toward the center of the roll.

Another feature of this invention consists in the provision on the cement applying roll of ribs which are obliquely arranged with respect'to the scraper so that as they come into position beneath said scraper their longest extent is oblique to the plane of its face. Formerly ribs have been provided which encircled cement rolls but their disadvantages have been two-fold: first, so long as the grooves between them were free, the cement has tended to work out through them to the exposed surface of the roll, and second, if any extraneous material was present in the cement these grooves became filled with it so that presently the scraper held back the cement almost completely, and the exposed surface of the roll ran practically dry. Ex-

. traneous material, such as particles of leather, cloth and certain dirt of an unclassifiable nature is present in all shoe manufacturing establishments, and a certain amount of this ultimately finds its way into the cement. The result,'therefore, has been that these rolls having circular ribs at first carried too much cement and finally carried too little so that it became necessary to remove them from the machine and clear out the grooves. Under certain circumstances too these circular grooves may be rendered are automatically ineffective in another manner. The particles of dirt may gather on the scraper and extend down into the grooves thereby transforming the scraper-into an effective comb which holds back practically all the cement. With the present construction, however, if particles of dirt get into the grooves they worked out and transferred to the stock instead of being pushed around and packed into the grooves. Moreover, the obliquely arranged ribs serve to cut from the bottom of the scraper any particles of dirt which may tend to clin thereto. The result is that the roll carries uniformly the proper amount of cement.

Another feature of this invention consists of a roll comprising independently yieldable sections, said roll being particularly adapted for use with cementing machines.

These and other features of the invention including certain details of construction and combinations of parts will be described in connection with the accompanying drawings and pointed out in-the appended claims.

Referring now to the accompanying drawings, Figure 1 is a perspective of a machine embodying the invention. Fig. 2 is a cross section on a plane passing between the sections of the respective rolls Fig. 3 is a detail showing a. skived sole between the rolls, the skived edges of said sole being bent up into contact with the applying roll, and Fig. 4 is a cross-section of a skived sole, the dotted lines indicating the position it assumes when subjected to the action of the rolls as shown in Fig. 3.

Upon a shaft 1 is mounted a cement applying roll. Above said roll is a cement supplying reservoir 2 provided with acon-- duit which terminates in a nozzle in contact with said roll.. This nozzle is shown in section in Fig. 2 and comprises a scraper or spreader 3 located with respect to the direction of rotation of the roll as shown in Fig. 2,, and a dam 4 arranged to yield in the direction of rotation of said roll so as to permit any surplus cement to be carried back into the conduit but to prevent said cement from working out of said conduit in the opposite direction. Attention is particularly directed to this yielding dam since otherwise the cement would tend to bank up on the outside of the nozzle at this point during the operation of the machine and to drip down upon the presenting roll (presently to be described) when the machine was not in use. In order still further to insure that no such dripping may occur whereby cement might be applied to the presenting roll -a plurality of V-shaped ribs 5 are formed upon the surface of said roll which,

as will be apparent, tend to hold the cement securely against dripping. v

ments and construction Although in the illustrated embodiment the ribs on the cement applying roll are shown as V-shaped, it should be noted that they are also arranged obliquely with respect to the scraper and that this oblique arrangement has distinct purposes; first, to cut from the operative face of the scraper any extraneous material which may cling to it and second to cause any particles of such matter which may become lodged in the grooves to be transferred to the stock. I

As has been stated the ribs in the illustrated embodiment are given a V-shape and in order to facilitate the production of such ribs said roll is made in sections 6 each providedwith oblique ribs and these sections are hel together with their ends abutting by bolts which pass through disks 8 fast to the shaft 1.

The presenting roll 9 comprises a plurality of sections 10 in the form of rings. Each ring is held in position by a plurality of supporting members 11, between which are placed springs 12 each section having separate supporting members and springs whereby it is separately yieldable. It should be noted that these springs act in opposition to each other as well as to force the supporting members outwardly so that said members are held spaced from the shaft. A shaft 13 revolubly mounted in a swinging bracket 14 carries near its ends disks 15 which are connected by bolts or rods 16, said rods serving as stops which cooperate with lugs 17on the supporting members 11 to limit their outward movement. The adjustof the presenting roll are such that the sections are revoluble with respect to each other and are independently yieldable radially of the shaft. The bracket 14 in which this presenting roll is mounted is pivoted at 18 to the frame and is normally held in raised position by a spring 19 which encircles a rod 20, said rod being pivoted to the frame at 21 and carrying threaded upon its upper end a wingnut 22 by which the motion of the carrier due to the spring may be limited. This spring 19 is provided to normally hold the bracket 14 and with it the shaft 13 in its uppermost position but to permit said bracket to yield to accommodate soles of different thickness, the springs 12 acting to force the thinner portions of the sole into contact with the cement applying roll as shown in Fig. 3.

The cement reservoir 2 is provided with slides 24 arranged to rest upon guides 25 so that said reservoir may be readilv removable. The scraper 3 and the yielding dam 4 are held in place by screws as shown, and the flow of cement is regulated by a valve 26 having in its effective portion the form of a mutilated cylinder as shown in Fig. 2. The shaft 1 carries fast and loose pulleys 27 meshes and 28. A presenting table 31 is adjust ably fastened to the front of the bracket 14: by wing-nuts 30 and a similar receiving table 29 is similarly fastened to the rear of said bracket. The base of the machine is adapted to be bolted to a table or other support as shown in Fig. 1, and an upstanding portion 32 carries the bearings for the shaft 1. The edges of the disks 8 are beveled as shown in Fig. 1 and cooperating with said beveled edges are Wipers 33 to direct the ocment toward the center of the roll.

in operation power is applied to the shaft 1 and the v alve 26 opened, the cement then passing into the nozzle. As the cement applying roll revolves the oblique ribs contact with the scraper 3 whereby the cement is confined to the grooves between said ribs, and inasmuch as said ribs and grooves form Vs as shown, the cement cannot work around the periphery of the roll and accumulate in any particular locality which accumulation might result in dripping of the cement upon the lower roll. Moreover, the oblique ribs serve to cut from the bottom of the scraper any lumps of cement or extraneous material which may cling thereto as well as to cooperate with the stock to remove from the grooves in said roll and transfer to said stock any such material which may become lodged in said grooves. The yielding dam effectually prevents the cement from working out beneath it and at the same time permits surplus cement, if any, to pass back into'the conduit.- As the stock (for example a skived sole) is fed between the rolls its thickest unyielding portion determines the amount of compression of the spring 19 and hence the position of the shaft 13 while the yielding sections force the thinner portions of the stock upwardly into contact with the cement applying roll.

It should benotedthat the machine is particularly adapted for cementing comparatively thick stock, such as sole leather, which is not of uniform thickness and that means are provided for distorting said stock so that the surface of the thinner portions to which it is desired to apply cement is forced into contact with the cement applying means.

For convenience the term cement has been used throughout the specification but it should be understood that the invention may be used in the application of any liquid or plastic substance having adhesive qualities.

The invention has been set forth in connection with a certain machine, but it should be understood that it is not limited in the scope of its application to the particular machine shown and described.
