PASTlNG-MACHINE FOR (DOLLARS, 840.

SPEGIFIGATION forming part of Letters Patent No. 676,793, dated June 18, 1901-. Application filed September 12, 1899. Serial No. 730,220. (No model.)

To all whom it may concern:

Be it known that I, ALBERT D. FENwIcK, a citizen of the United States, and a resident of Boston, Massachusetts, have invented certain new and useful Improvements in Pasting-Machines, of which the following is a specification.

My invention relates to pasting-machines, and is particularly intended for use in apply- :0 ing paste to the blanks of collars and ends preparatory to pasting such blanks together and stitching them. Heretofore this work has been done by hand and has been slow and not altogether satisfactory, as a careless operator might apply too much paste or apply it at the Wrong points on the blank.

It is the object of my invention to provide a construction that shall make it possible both to apply the paste more rapidly than by hand and to do it in a more satisfactory manner.

To this end my invention consists in combining with suitable actuating mechanism a series of paste-carrying tubes or fingers arranged and adapted to deposit an accuratelyregulated quantity of paste at any desired points on the blank to be pasted.

Another feature which characterizes my invention consists in providing for the paste areservoir from which the air may be wholly 3o excluded, so that it cannot mingle with the paste and cause it to sour or spoil.

A third novel characteristic consists in combining with the paste-applying means novel mechanism for accurately regulating the quantity of paste supplied thereto Within any desired limits.

Still another feature consists in so arranging the paste-applying fingers and the operating mechanism that the paste may be applied at any desired points and to different forms and sizes of blanks.

These and other features of my invention will be particularly explained in the following specification and clearly set forth in the 5 claims.

Referring now to the drawings, in which I have illustrated one of the modes of embodying my invention, Figure 1 is a side elevation of the entire machine. Fig. 2 is an end elevation thereof. Fig. 3 is a plan view showing the means for supplying the paste to the ends of the fingers in properly-regulated quantities. Fig. at is a vertical sectional View on the line 4 4 of Fig. 3. Fig. 5 is a central verticalsection showing the device for filling the paste-tubes, one of the tubes being shown immediately below ready to be attached for filling. Fig. 6 is a plan view of the strainer contained in the filling device.

In the practice of my invention as illustrated in the drawings I provide a suitable table a resting upon the framework Z) of the machine, which serves to support in proper position the blanks to be pasted.

The paste carrying and applying device comprises a tube or reservoir 0, provided at its lower end with a short substantially conical nozzle d, which has an outlet at its apex. The nozzle is detachable fromthe tube. Upon the exterior of the nozzle is secured a ring or guard 6, whose lower edge lies slightly below the plane of the contracted end or point of the nozzle. A plunger or pistonf, having a suitable packing-disk secured to its bottom,

. fits closely the bore of said tube and is forced downward by means of a screw threaded plunger-rod g, whose lower end rests loosely in a socket on the upper face of the plunger. The plunger-rod is prevented from turning by a spline connection h with the flanged head 2. An internally-threaded rotatable hubj, having secured to its top ratchet-disk 7r, serves to depress the plunger in the tube. Gibs or pins Z may be employed to prevent the withdrawal of the hub from the head Without interfering with its turning. An arm or lever m, loosely mounted to turn on the hub j and provided with a spring-pawl n, serves to intermittently rotate the ratchetdisk 7a and the hub The means for oscillating said pawl-carrying arm to actuate the disk consists of a reciprocating rod 0, mounted to slide in suitable brackets and having projecting fingers engaging with the forked ends q of the arms m, so that as the rod slides it moves the arm or about the hub j as an axis. Each forward movement of the pawl carries the disk with it; but on the return movement of the pawl the disk is stationary, being held in place by spring-detents r. The fingers 19 may be secured to the rod 0 by means of sleeves provided withset-screws, so that they may be properly adjusted. The slide-rod is held normally pressed to the right through the action of the spring 5 and the slotted bellcrank lever 15, which is connected with the 5 slotted link u by an adjustable stud w. The slide-rod 0 is moved forward by means of the arm a on the rock-shaft b, which is actuated by a swell on the cam c, said arm a being connected to the bell-crank lever 25 by means of the chain (1. Motion is imparted to the drive-shaft e from the power-shaft f by means of the clutch-hub g, the sprocket-chain h, and its two sprocket-wheels, the idlersleeves 22, carrying the pinion i, and the gear j, which meshes with said pinion and is secured to the drive-shaft e. A treadle 70 serves to keep the clutch member in operative engagement when it is desired to run the machine. The drive-shaft c carries the cam 0, whose function has already been explained. It also carries another cam Z, which actuates the rock-shaft m through the medium of the arm n. The rock-shaft m is provided with slotted forked arms 0, which engage with pins 19 on the sliding sleeves g, which sleeves carry. lifting-rods r. These lifting-rods support cross-heads s, in which are secured the rods t, which thus form a carrier or frame for the paste-carrying tubes, which are adjustably secured thereon by means of the brackets u,the flanged heads t', and the clamping wings or collars w, the brackets it being held rigidly and adjustably in place on the rods by means of the set-screws a To permit an adjustment of the tubes transversely to the rods 16, the bracket may be slotted, as shown at b in Figs. 3 and 4. It is sufficient, however, to make the middle tube only adjustable in this way. To accommodate this adjustment without varying the length of the arm m,that moves the ratchet-disk, the sleeve 0 which carries the pin 19, may be adj ustably mounted in a yoke d adjustably secured to the slide-rod 0. As the tube is moved back in its supporting-bracket the pin -carrying sleeve may be moved back a corresponding distance, so that it will properly engage the forked end (1 of the arm m.

From the foregoing it will be seen that the mechanism for actuatingthe plungers acts independently of the means for reciprocating the tubes, so that the extent of movement of either mechanism can be varied without atfecting the movement of the other. Moreover, the change of relative position of the tubes to each other does not interfere with or vary the action of the pasteexpelling means, since the expelling mechanism is capable of adjustment to accommodate any change in position of the tubes.

The operation is as follows: A pile of collar-blanks is laid upon the table in proper position beneath the paste-applying fingers. The operator then depresses the pedal and thus starts the machine. Through the medium of the cam Z, the rock-shaft m and its projecting arms, and the connecting-rods the paste-fingers are alternately raised and lowered. As will be understood, the cam Z and the rock-shaft arms raise the verticallyreciprocating framework positively; but its descent is due only to gravity. In order to prevent jar, as well as to ease the running of the machine, the rock-shaft may be partly counterbalanced by a weight g. The cam c is so coordinated in its action with reference to the cam Z that it depresses the arm a, and thereby moves forward the slide-rod 0 when the paste-fingers are at the top of their traverse. This forward movement of the sliderod swings-the arm m through the arc of a circle, moving the ratchet-disk 76 and the hub j through a corresponding arc. The internal thread of the hub or sleeve j, acting upon the thread of the plunger-rod, causes said plunger-rod and the plunger to slightly descend, and thus to force a small quantity of paste through the contracted nozzle 01, so that a drop of paste falls from each tube upon that point of the blank directly under it. The guard 6 projects slightly beyond the lower end of the nozzle and prevents the tube from descending far enough to allow the nozzle to come in direct contact with the blank, thereby making it impossible for the blank to stick to the paste-finger nozzle when the finger rises. As will be understood, the distance which the plunger descends at each operation depends upon the extent of the are through which the ratchet-disk is moved by each stroke of-the slide-rod, which in the construction shown is determined by the length of stroke of the slide-rod. The length of this stroke is varied by shifting the position of the adjustable stud or connecting-pin 10. As shown in the drawings, this pin is set to give the maximum stroke, at which. point the ratchet may be turned through an arc of, say, six teeth. By setting said pin at the bottom of the slot in the lever 25 it is obvious that the length of the stroke of the rod will be shortened in the ratio that the radius of the movement of the pin in its lower position bears to the radius of its movement in the highest position. As the quantity of paste applied will depend upon the distance that the plunger is depressed on each stroke, it will be seen that the feeding of the paste can be absolutely and accurately regulated by shifting the pin to.

I have provided a special device for filling the tubes or reservoirs with paste without allowing the air to mingle with it. One form of this device is shown in Fig. 5 and is somewhat similar in construction to the paste tubes. It comprises a tube 1, which is screwed into a supporting-head 6, which carries a rotatable hub or sleeve 7, to which is secured a hand-wheel S by means of gibs 9. This hub is-interiorly threaded to receive the threaded plunger-rod 5, which has a splinegroove connect-ion with the head (i, as shown at 6, which prevents the rotation of the plunger-rod, though permitting-it to move vertically in said head. The piston or plunger 4 stares is secured to the end of the rod 5 and is provided with a suitable packing-disk to make it fit snugly in the tube. The device is supported by the brackets 2 and 3, which may be attached to a backboard A or other suitable support. To the lower end of the tube is fitted a funnel-shaped cap or nozzle 10, whose central orifice is fitted with a female thread and receives a screw-plug 11. A strainerdisk 12 is supported at the lower end of the tube. The tube 1 is made very much larger than the paste-tubes c and is filled solid with paste. i

When it is desired to fill the tube 0, it is unscrewed at the top from the head i, care being taken to push the plungerf to the lower end of said tube, so that its under face is about flush with the lower end of the tube. The screw-plug 11 is then removed and the hand-wheel 8 turned until the solid core of paste appears at the mouth of the nozzle or cap 10. The tube 0, with its lower end, containing the plunger, uppermost, is then screwed into the female thread of the nozzle 10. The plunger 4is then forced down, thus squeezing the paste in a solid mass into the tube 0 without the admixture of any air. \Vhen the paste has driven the plunger f nearly to the other end of the tube a, the operation is stopped and the tube is-removed and replaced in the machine.

The advantages secured by my invention involve the keeping of the paste in perfect condition, the avoidance of waste by not permitting the paste to dry or sour, and the accurate regulation of the quantity applied, so that neither too much nor too little will be used in each blank. It will be noticed also that the mechanism is so arranged that it acts in precisely the same Way on the blank whether the pile of blanks be large or small. It also permits the application of the paste to exactly the right points of the blank what ever the size or shape of the collar or cuff blanks may be.

The rapidity with which the machine can be run is in practice limited only by the speed with which the operators can pick off the successive blanks and paste them.

It will be observed also that the paste-applying devices need have but a simple reciprocating movement in a vertical plane and that there is no necessity of employing mechanism for compounding a lateral movement with the vertical movement. As the weight of the reciprocating parts can be nearly counterbalanced, it is obvious that but very little power is required to run a machine.

It will be understood that the machine shown and described herein illustrates only one embodiment of my invention and that changes can be made in the form and arrangement of parts and that different mechanical movements from those actually described may be substituted to accomplish the same results.
