Specification of Letters Patent.

Patented may 11, 1909.

Application filed May 4, 1908. Serial No. 430,778.

To all whom it may concern:

Be it known that I, LORING VINCENT Esrns, citizen of the United. States, and resident of New York city, in the county of New York and State of New York, have invented new and useful Improvements in Past-ing- Machines, of which the following is a specification.

My invention relates to machines for applying paste or for the performance of analogous purposes or functions and is addressed particularly to situations wherein paste or other adhesive is to he applied in small regulated quantities, in spots rather than in means, and where objects to which the paste is to be applied are light and require careful handling.

More especially, my invention is peculiarly adapted to the work of applying the paste to thin blanks such as constitute the component arts of collars, cuffs, shirt bosonis and the like.

The pasting machine herein illustrated and described and which exemplifies my invention, is contrived especially for applying paste to collar and oufi' blanks. 1n the manufacture of collars, cuffs and shirt fronts,

blanks are cut from sheets of cloth andlaid in several plies which are stitched together to form the composite which finally appears as the finished article. These blanks in order to conform to the many styles and sizes produced by the manufacturer of such goods, are cut in a great variety of shapes and it is essential that the several components, say of a collar, such as linings and to s, be laid in accurate register with each ot er so that when stitched together they shall conform to the predetermined style and size of the finished article. In order to hold these components of the finished structure in accurate register with each other, it has been the practice for a long time to paste to ether the several plies with a soluble ad esive which holds the pieces in correct relation previous to and during the stitching operation. Heretofore the almost universal practice has been to do this pasting by'hand; pasting machines have been contrived for the purpose but, so far as I am informed, they ave not been practically satisfactory nor have they in any sensible measure superseded the still prevalent hand operation.

The asting o eration in thec-ollar, cuff and shirt manu act-ure is to be performed with reference to subsequent operations; the paste must be a plied to blanks only on such port-ions thereo as will not subsequently be pierced by the sewing machine needle; if a spot of paste is applied at the place where stitching will be done, the presence of the hardened film of paste is almost certain to break, the sewing machine needle. The paste is, therefore, applied to the blanks in this manufacture in small isolated spots, and in hand operation care has to be taken to see that these spots of paste are ap lied by the brush or other pasting utensil at proper places and in pro erquantities upon the lank. When the flank is thus spotted with paste another blank is laid over it so that the two register accurately, they are then smoothed together and the paste allowed to set and secure the two pieces in their proper relation. An excess of paste even when it is applied in these isolated spots is, moreover,

embarrassing or injurious during the subsequent manipulations of the material. Consequently, the requirements of this special situation are that paste shall be applied to a blank in isolated spots properly located and in minute measured. uantities.

The result accomp ished by my invention is the regular and uniform automatic application of suitable paste spots inproperly measured quantities to ablank. 1 I

The physical conditions to the realization of my invention are the rovision of a suit. able supply of adhesive, tlie periodic abstraction from that supply of small measured uantities of adhesive and the impression t ereof u )on blanks in regular su'ccession.

In order 1; mt these physical conditions shall I be uniformly maintained, a mechanism is re quired .which does not employ conveying tubes for the adhesive, or any surfaces upon -which the adhesive will quickly harden so as to clog the operation of the machine. A characteristic of mechanism which exemplifies my invention is the abstraction from the V aste supply of individual smallfilms of adliesive and their transfer to the object to be pasted. Such a mechanism is illustrated in the accompanying drawings, in which,

Figure 1 is a side view of a pasting machine; Fig. 2 is a front elevation; Fig. 3'i's a plan view; Fig. 4 is a detail on a largerscale showing the paste reservoir and paste transferring members; 5 a detail showing the construction of the paste transferring n1embers; and Fig. 6 a further detail illustrating in the for the less belt B, is mounted on the frame Aand passes over the rollers B, B at opposite ends of the frame, the roller B bein mounted in an adjustable bearing 13 whic is provided with adjusting devices, as the screw B for the urpose of taking up the stretch of the belt B. The roller B is the driving roller for the conve er B and is driven bymeans of the disk D wiich, in turn, derives motion frictionally from the friction roller D which gpneral form of a table. A' conveyer slides on and rotates with the shaft D this shaft being driven by the bevel gears D'', D" from any appropriate source of'power. The speed of rotation of the disk D is determined by the position thereon of the roll D. position is regulated by the shipper lever D which is pivoted u on the frame and carries a pin (1 which catc es in holes or depressions dt upon the sector bracket D. The lever D -may be made of sulficiently resilient material to allow the pin (1 to be sprung out of one of the depressions d and transferred to another. One set of blanks as, for instance, collar linings, is placed in the tray T at the rear end of the machine and another set as, for in: stance, collar tops, in the tray T which extends across and over the conveyor B near the front of the machine.

The movement of the conveyer B carries blanks in succession upon the conveyer from the rear to the front of the machine; in their traverse they pass successively beneath the asting mechanism which is located midway etween the front and the rear ends of the machine.

The standards E are mounted on either side of the machine frame and contain the bearings and supports for the pasting mechanism; the bearin slots E contain block bearings for the rolTs J and K and theslot E v contains the bearing block for the shaft on which the paste transferrers 01' spotters are mounted. A trough F constituting the paste reservoir is supported between the standards E and the paste carrying roll K dips beneath the surface of the paste in the trough F and is given a movement of rotation by means of the belt and pulleys at K in the direction shown bythe arrow in Fig. 4. The paste carrier K carries on its surface a film of adhesive, and the roll J driven by the belt and pulleys at 7', acts as a film-regulator by ressing upon the upper portion of the roll s reading this film to a uniform thickness. he paste transferring members are mounted upon the shaft L; these in the illustrative example shown in the drawings, consist of disks (see Fig. 4), in the circumlanks, in the instance shown an end' This ference sl ofwhich, the tubes L are mounted. These tubes serve .as carriers for the stems L '(see Fig. 5) and, at the outer ends of these stems there are secured elastic tips L"-, preferably c'omposed' of rubber and slightly cupped at their outermost surfaces. These tips, in the illustration here shown of my invention,

"constitute the paste transferring members which a )ply paste in spots to the blanks. Springs f housed in the tubes L serve to hold the stems L yieldingly pressed outward. The shaft L is driven by .the pin wheel G whereof the pins Gr engage with a sc- 7 ries of gromets b secured to the conveye'r belt B a ong one margin thereof. The pro portions of the Wheel G are such that as the tips L of the stems L come in contact with the blank upon the conveyer B they move at the same rate as the surface of conveyer B and conse uently do not tend to rub on the blanks. T ms the contact of the tips L with the blank on the conveyer B will not-displace the blank from its position on the conveyer. The relative positions of roller K and shaft L are determined so that each of the paster tips L will come into gentle pressure contact with the paste covered roller K, preferably just enough to flatten out the'cupped extremity of the tip L When, in the rotation of these 1nembers, the tip leaves the roller Kand assumes its normal form, it will remove from the roller K a small paste carried by the r0 ler. tip L comes in contact with the blank, the tip presses thereon, squeezing the small quantity of paste carried by the tip upon the blank, depositing it there preferably with suflicient pressure to cause the paste to enter the meshes of the blank rather than by de ositing it only by touching it upon the sur ace. The sprin support of the stems L al lows a reasonab e 1'. nge of adjustment between the shaft L and roller K and also between the shaft and the surface of the conveyer B; moreover, should any foreign substance accidentally lodge u on the convcycr B and be struck by one of t e paster ti s, the s )ring support of its stem L will one le the o ject to pass without damaging the mechanlsm.

In order to prevent the pasted blanks from adhering to the aster tips L I provide the strippers H whith consist of rollers arranged just m-front of the shaft L and attached to the ends of hinged or flexible arms H, the latter being secured to the reservoir F. These strippers bear u on the blanks as they pass under the shaft 1 1 and stri them from the paster tips as the latter rise 'rom the conveyer. As the blanks come forward under the tray T, a second 0 erator takes the sec ond set of blanks one y one from the shelf and lays them upon the pasted blank, securing the two blanks together by means of the paste spots previously applied to the ortion of the film of When the paster blankson the conveyer B by the paste transveyer B onto the delivery band C which is an endless belt passing over the rollers C and C, the roller C being driven by gears C, B, the latter rotating with the shaft of the conveyer roller B. In order that the blanks which are lightly secured together by moist aste ma be so guided in their fall to the and C t at they will not be mutually'displaced, I provide the guide apron N (see Fig. 6) which is a curved adjustable sheet of smooth material, such as sheet brass, hung by arms N upon a bar N" which is ad inst-able horizontally upon the brackets N as by bolts and nuts at n". The bracket N is vertically ad'ustable upon the side hanger N as by bolts. and nuts at n. This hanger N is secured at the front corners of the machine, the securing means being at N As the pasted blanks tip forward over the roller B, they are turned b the apron N and deposited entl upon the band C vhich conveys the lan to the tray T The operation of the above described machine is as follows: Collar lining blanks, for instance, being stacked on the shelf or tray T and the machine being started, an operator places the lining blanks one by one upon 'pers H and the tray the front of the machine.

the conveyer B, being guided by the suitable marks upon the surface of the conveyer so that the blanks shall be placed properly to receive paste from the paster tips. As this procession of blanks passes under the pasting mechanism, the paster tips of the paste transferring members having taken each its measured supply of paste from the roller K, deposit the paste upon the blanks one after the other; the blanks ass under the stripand emerge toward There a second operator takes the collar top blanks one by one from the shelf T and places them upon the pasted lining blanks taking care that the tw blanks register properly with each other in each instance. RThen the pasted pairs ol' blanks pass from the front of the machine down over the guide apron N and are deposited upon the band C which conveys them to the shelf T The speed of the machine may be regulated as abpvedescribed by means of the shipper D so that the speed of delivery of pasted blanks m y be within the operating capacity of the person at the front of the machine.
