CEMENTING-IVJIACHINE.

Specification of Letters Patent.

Patented Feb. 8, 1916.

To all whom it may concern:

Be it known that we, EDWARD Enronson and JOHN W. Coseaovn, citizens of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, and at Medford, in the county of Middlesex, in the State of Massachusetts, respectively, have invented certain improvements in Gementing-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 coating material to stock and is herein illustrated in connection with a machine for applying cement to pieces of fabric which are to be used to linethe uppers of boots and shoes. In machines of this class it is common to provide a cement applying roll of comparatively large diameter upon which the fabric may be lightly laid, nap side down, and from which said fabric may be removed to be placed upon a vamp or other part of the upper of a shoe. Itis desirable to coat the nap surface only of the fabric with just suiiicient cement to cause it to adhere to the leather so that the nap may form a flexible connection between the leather and the body of the fabric, the body itself not being wet with the cement and consequently not being stiffened when the cement has set. i

One of the principal difliculties which has arisen with machines of this class has been that the parts of the machine have become more or less covered with thickened cement mixed with particles of lint or other foreign matter. To prevent this, doctors, scrapers and strainers have been used; but owing to the tendency of the cement to become gummy when exposed in small quantities to the air and to the fact that a certain amount of lint is transferred from the fabric to the machine, it is necessary to clean the parts of the machine at intervals.

The general object ofthe presentinvention is to facilitate this cleaning; and to this end one feature ofthepresent invention consists of a readily removable receptaole-upon which are mounted the doctor, the scraper, the strainer and the cement supplying roll. It is thus possible by pulling the receptacle from beneath the cement applying roll to obtain ready access to the various parts of the machine.

In machines of this class the bearings of the cement supplying roll are particularly troublesome, and a. further feature of the invention consists in a machine of the class described of open-sided bearings carried by the cement receptacle in which the trunmons of the supplying roll are received. -With this construction, when the cement receptacle vention is embodied; Fig. 2 is a detail per-.

spective of one end of the cement receptacle and the bearing which is pivoted thereto; Fig. 3 is a perspective of an end of one of the trunnions of the cement supplying roll; and Fig. 4 is a perspective of the machine, the base having been broken off.

Slidably mounted in the base 1 of the machine and held in adjusted position by set screw 3 is a column 5 to the upper end of which is fast a supporting table 7 having a flat upper face upon which the cement receptacle 9 rests. This table is designed to permit the application of heat and for this purpose has a socket to receive a heat unit 11 which may be connected with any suitable source of electricity. The table also carries a U-shaped length of steam pipe 13 which may be connected to a source of steam; and either or both methods of applying heat may be used as desired.

The cement applying roll 15 is fast to a shaft 17 which is rotatably mounted in uprights one of which is shown at 19. To the shaft 17 is fast a gear 23 which is driven through a pinion 25 from a driving shaft 27, said shaft being arranged to be clutched when desired to a pulley 29 by the manipulation of a hand lever 31. a The clutch itself will not be described further since the details of its mechanism form no part of this invention. In order to supply cement to the applying roll 15 a cement supplying roll 33 is arranged to contact at its upper portion with the under portion of the applying roll 15 and to turn with its lower portion dipping into the cement in the re ceptacle; and this supplying roll is formed at each end with raised portions 16 which determine the thickness of the coating of cement carried by said roll.

In the operation of the machine the applying roll 15 is rotated in a counter-clockwise direction as viewed in Fig. 1; and in order to regulate the thickness of the coating of cement which 1s carried by sald roll, a

doctor 3-1 is fast upon studs 35 carried bythe receptacle 9. To the right hand stud,

as viewed in Fig. 1, is fast a lever 37 is received in an arc-shaped groove, V-

shaped in cross section, said groove being formed in a projection of one wall of the re ceptacle 9. In order to remove from the applying roll the lint and dirt which accumulate upon it, a resilient scraper 17 is located as shown in Fig. 1, said scraper being fastened to one wall of a raised compartment the bottom of which is formed by a strainer 49.,

In machines of this class it is very desirable that ready access to the various parts beprovided in order that the cleaning of the parts may be facilitated. The mounting of the doctor, the scraper and the strainer upon the cement receptacle, as has been described above, permits ready access to these parts since the receptacle is so mounted that when the latch 52 is swung from the posi tion occupied in Fig. 1 to that occupied in Fig. 2 the receptacle may be pulled out from beneath the applying roll 15. In order that the supplying roll 33 may be removed from the receptacle, said roll is provided at each end with a trunnion 51 which is received in an open-sided bearing 53. Each bearing is pivoted upon a screw 55 which is threaded into an end wall of the receptacle, said bearing being urged upwardly about its pivot by a spring 56, see Fig. 4:, which rests upon an adjusting screw 57 and supports a plun ger 59. The screw, spring and plunger are, seated in a suitably shaped socket in a boss on the receptacle 9, and over each plunger projects an ear 61 which is integral with the of lint is distributed about the machine,

and this lint is particularly troublesome when it gets into the small space between the ends of the trunnion 51 and the adjacent walls of the bearing 53. In order, then, to force such lint out of said space and thus prevent interference with. the rotation of the supplying roll, each trunnion is provided at its end with flaring grooves 65 which cross the radii of said trunnions. In the illustrated machine these flaring grooves are straight and are arranged obliquely to said radii. The direction of rotation of the trunnions is indicated in Fig. 1, from which it will be clear that any-lint which may be wedged against the end of a trunnion will be worked outwardly to the periphery of said trunnion. In order to permit the escape of such lint, a passage 67 is provided in the lower wall of each bearing 53. l/Vhen,

therefore, a piece of lint gets wedged in be tween the end of a trunnion and the adjacent wall of the corresponding bearing, it will be worked outwardly by the grooves 65 and finally forced into the passage 67.

In order'to protect the cement from dirt and dust, a cover 69of sheet metal may be hung upon a flange of the doctor 34 as shown in Fig. 1. A second cover 63 is pivoted at the rear of the receptacle and extendspartially over the compartment which contains the strainer.

In the operation of the machine power is applied to the shaft 27, and the applying roll 15 is thereby rotated slowly, said roll rotating the supplying roll 33 and causing the last named roll to lift cement from the receptacle and deliver it to the applying roll. Il l1en it is desired to clean themachine the latch 52 is turned down to the position shown in Fig. 1 and the receptacle is pulled out from beneath the applying'roll. The supplying roll is then lifted out. The various parts of the machine which are liable to be covered with more or less hardened cement and bits of lint are thus readily exposed so that said parts may be cleaned very quickly. After the cleaning has been accomplished, the supplying roll 33 serves as a stop to limit the inward movement of the receptacle, .and when the receptacle has reached its inward position the scraper 4:7

and the doctor3l are in operativerelation to the applying roll 15.

Although the invention has been set forth not limited in the scope of its application to the particular machine shown and described.
