CEMENT'ING-MAOHINE.

Specification of Letters Patent.

Patented Oct. 14, 1919.

Application filed May 1, 1918. Serial NO. 231,917.

plying cement to various objects. It is especially applicable to machines for cementing fabrics and the like arranged in one or more layers of varying thickness.

In the manufacture of various goods, such as waterproof garments including raincoats Y and ponchos, a portion may be produced in which one layer of fabric atseamsor hems extends over another irregularly, so that along the area which is to be cemented the Work may be at some points" two layers in thickness and at other points but one. A machine for uniformly applyingthe cement to work'of this character is furnishedbythe present invention.

A feature of he invention consists in a work-support arranged in sections situated opposite the cement-applying member, one of the sections being yieldable and normally lying at a difierent distance'from the applying member than another section, it usually being nearer to said applying member. Preferably, the yield able section of the work support is relatively narrow as: compared with the adjacent section,'and is here shown in the form of aspring-finger, while the wider section may be a roll, to the periphery of which a portion of the finger is concentric.

In connection with the following descrip- 'tion and claims,'other features will appear.

In the accompanying drawing,

Figure 1 is a perspective view of one em- 1 bodiment' of my improved machine, viewed from below;

Fig. 2 isa similar view of the work-supporting lever with its elements separated; a

Fig. 3 is a partial vertical 860171011 of the work-support somewhat enlarged and Fig. 4 shows in perspective a portion of the work which may be operated upon.

A frame 10, upon which is supported .a

cement-tank 12 and having'journaled in it a shaft 14 for the cement-applying member, maybe substantially as disclosed in my Patent No. 1,242,925, dated October 16, 1917.-

The applying member 16 for receiving cement from the tank and transferring it to the work is shown as a solid roll having transverse cement-pockets 18 joined by distrlbuting grooves 20 formed circumferentiallyof the applying face of the roll. Fulcrumed in the frame, as in the previously mentioned patent, is a carrier-lever 22 having at its outer end an upwardly extending portion 24.v ournaled in this extension is a horlzontal spindle 26 having fixed upon its inner extremity a roll 28, which furnishes one section of a work-support. The outer edge of the roll 28 is preferably in vertical alinement with the opposite edge of the applying roll, and the supporting face extends for a considerable'portion of the width of the applylng roll adjacent to its opposite edge. Beyond the roll 28, between it and the inner edge of the applying roll, is a yieldable section of the work-support. This is shown as a spring-finger 30 of some such fiexlble materlal as steel, havmg the same curvature as the periphery of the roll 28.

It extends from the rear of the machine over the lever 22 concentric to the roll, and then vertically downward to a shank or enlargemen't 82, by'which it is mounted in the lever.

The shank lies in a recess or vertical way 34,

being heldtherein by ascrew 36 threaded 111130 the lever with its head overhanging the position'as to furnish a continuation of its supporting surface.

The normal relation maybe changed by raising or lowering the I shank in the way. 34.

At the outer edge of the supporting roll' 28 beyond the edge of the applying roll 16 is, another work-supporting section, which maintains the portion of the material adjacent to that operated upon horizontal, so

- sisting of a curved table 38, the outer surface being preferably in horizontal alinement with the periphery of the roll28. The table is carried by a shank 4:0 recessed at 42 to receive a projection 4a at the end of the lever 2-2, thusfurnishing a way permitting vertical adjustment of the table. The table is held in position by a screw &6 passing through a slot in the shank 4:0.

A. gage 48, adjustably held uponthelever 22 by a screw 50, determines by its contact with the edge of the work the points of application of cement thereto. The contact face of this gage is closely adjacent-to the inner edges of the roll 16 and finger 30.

In Fig. t isillustrated a fragment of an edge or hem portion of a garment which has been cemented by this machine, It consists of inner and outer layers I and 0, respectively, of fabric, secured. bya line Laof stitching. At 0 the inner layer projectsover the'outer irregularly, so that portions come fully to the edge of the layer 0, while other portions extend only to i at a little distance from the edge of the layer 0. Inapplying the cement indicated at C to both a strip along the edge of the layer I and to the portions of the layer 0. over which the 'projec tions 0 do not extend, the finger 30 is preferably so adjusted that normally, \orwhen out of contact with the work, its uppersurface lies outside the periphery of the ro1l28 a distance substantially equal to, or at least not less than, the thickness I of the inner layer of fabric. As aresult of this, when the work is introduced between the applying roll and the work support and is advanced for the application of cement-bythe former, the finger 30, which is of approximately the same width as the projection portions 0 when in contact with; these projections, yields 0 that it liesat the sameleVel-as the periphery of the supporting roll. YVhena space between the projections 0 is reached, the fingermoves upwardly until the inner surface of the layer 0 is raised to the same level as the layerI, so that the cement is distributed uniformly bythe roll 16 over the entire surface.- For any variations in the thickness of the material the finger readily yields, whilealways holding the edges of both layers of fabric against the applying roll.-
