HENRY E. T RRY, or PHILADELPHIA, PENNSYLVANIA.

MACHINE FOR APPLYING To all whom it may concern:

Be it known that I,"HENRY E. TERRY, a citizen of the United States, and resident of Philadelphia, county of Philadelphia, 'and State of Pennsylvania, have invented an Improvement in Machines for Applying Reinforcing Means to Rug-Seams, of which the following is' a specification. I

This invention relates to a machine for applying a reinforcing means to the seam or seams of a rug or the like, in order to conceal the seam and prevent the same from opening up or stretching in the ordinary manner. I I I The invention has as an object to provide a machine for automatically feeding a seamedrug, carpet or the like, into operative relation with a reinforcing material-or tape and automatically aflixing such rein forcing means permanently-to the seam-or seams, whereby the seams are permanently coveredat the rear side of the rug.

It has for a" furtherobject to provide a means for softening and stretching the seams of the article and also pressing the stretched seams preparatory to receiving the reinforcing material. I

It has for a further object to provide an indicating means for determining the proper alinement of certainadjuncts of the mechanism with the seam or seams so that the proper action takes place in the desired manner. a 1, k

It has as a further object to provide a means for applying a coating "of adhesive materialito one side of the reinforcing tape and automatically-feeding such tape into juxtaposed position with respect to the seams of the-article. 1 f I I 'It has for a further object to provide a means for varying the position of the coated tape -whereby its I position I with respect 'to' the seam is presented with exactness. It has for a further object to provide a 45 means for pressing the coated tape into-position upon the seam and providing a means for drying the adhesive to'permanentl'y secure the tape to the article. II I I My invention also comprehends details of 50 construction which, together with the features above specified,-will be better understood by reference to the drawings, in

away for clearness of illustration; Fig. 2 represents a sectional elevation on line 22 of Fig. 1; Fig. 3 represents a section on the hne 3-3 of Fig. 2; Fig. 4 represents a section on line44 of Fig. 1; Fig. 5 represents a section'on line 5-5 of Fig. 1; Fig. 6 represents a side elevation, partly in section, of the adhesivejapplying mechanism; Fig. 7 represents a' detailof the scraping mechanism used in conjunction with the adhesive applying means; Fig. 8 represents a section through one of the seams of the material showing the finished-seam with the reinforcing material in place.

Si 'lar numerals of reference indicate corresponding parts.

1 designates the main frame of the machine secured to which at the receiving end thereof is a plate or-board2 arranged in an inclined position and serving to receive the material, cloth, rug, carpet or the like before it enters the machine. Adjacent this board 2 and normally resting upon the same .thereis a roll 3 carried'by arms 4 and suitably hinged as shown at 5 to the frame 1 so that it may be raised or lifted in order width of material uponthe board 2. As soon as the material is properly positioned the roll 3 is released and serves by its own welght as a means to keep the material free from wrinkles and in propercondition to enter the machine.

In the present instance the receiving board 2 terminates adjacent a conveying mechanism which is adapted to engage the material and feed it into proper relation to the operating adjuncts of the machine. As here shown, the conveyer mechanism consists of a 'pair of toothed conveyer belts 6 suitably attached to the respective chains 7 which are driven by the sprocket wheels 8 and 9, the former pair of sprockets being carried by and fixed to the driven shaft 10 while the latter pair of sprockets is similarly connected to the driving shaft 10, this latter receiving its motion from a chain and sprocket mechanism 11, driven from any suitable source of power. I

12 designates a .pair of rods fixedly secured to the frame 1 and preferably arranged in parallel relation to the shaft 10 for supporting the hangers 13 which carry the grooved guides 14. The grooved portions of the guides are adapted to receive the teeth of the conveyer so that the material is firmly gripped during the feeding operation. It will be obvious from Fig. 1 that the hangers 13 respectively support opposite end portions of the guides 14, the arrangement being such that the innermost end of each of the guides, as well as the adj acent conveyers, are spaced apart somewhat farther than the outermost ends of these parts. relation of -the conveyers is to initially stretch the material as it enters the machine so that the seams are stretched in a desired manner to bring the seams and the sections of the material into the same plane to eliminate the ridge generally formed by such a seam. The two conveyers 6 are driven from the sprockets 9 and move across the top or table 15 of the machine in a direction away from the inclined board 2, as will be understood. a

In the present embodiment of my invention I have shown a machine adapted for use with a rug or carpet having four seams, but it will be noted that one of the supports for the conveyor frame 16 is removably attached to the cross frame 17 and may be shifted so that material of less width or less number of seams may be operated upon if desired. For this purpose the cross frame 17 is apertured at 18 to permit the conveyer frame to be bolted in the position desired.

19 designates a steam pipe extending transversely of the machine and suitably supported upon the machine for sliding movement with respect to the sides of the machine, the said pipe having connection to a suitable source of steam supply and exhausting at a suitable point by way of the pipe 20. This steam pipe 19 is provided at intervals with discharge openings 21 corresponding in number to the number of seams in the material, and each is located so as to discharge the steam directly against the adjacent seam. In view of the fact that" the pipe 19 is below the top 15, the latter is apertured at a corresponding number of points as shown at 22 so that the steam may contact directly with the back of the material against the seam.

23 designates an arm attached to the steam pipe 21 and located above the table 15 so that the pointer 24, which is secured to said arm, may be positioned directly above the seam and thus determine the correct operative position of the steam discharge opening 21 with respect to the seams. Thus, for example, if the article enters the machine with the seam to one side of the pointer 24 it will be apparent that the steam outlet 21 will also be to one side of the seam rendering it ineffective for the purposeintended. It therefore becomes necessary to shift the arm until the pointer is directly alined with the seam, thereby insuring the it proper discharge of the steam.

The object of this diverging- The initial operation of feeding the rug or carpet to the machine, therefore, consists of placing the article upon the inclined board 2 beneath the roll 3, brin'ging'it into position to be engaged by the toothed con-.

and 28, the rollers 28 being rotatably mountt ed upon the shaft 10 while the rollers 27 are rotatably carried respectively by the frames 29 above the material, these Patter being mounted for pivotal movement upon one of the rods 12 and held in operative po sition by the counterweight 30. As an additional feeding means I preferably provide a suitable number of toothed rollers 32 mounted to rotate with the shaft 10 and projecting through suitable openings in the table 15. In the present instance I nave indicated but one set of seam-pressing rollers for engaging the material before the tape is supplied to the seam, but it will be understood that other sets may be employed if desired without departing from the spirit of my invention.

After the stretched seam has been pressed by passing between the sets of rolls 27 and 28, it is ready for the application of the tape which is designed to protect the seam and hold it in its flat condition to prevent ridges being formed and also prevent the seam from opening up at the backof the article. The tape-applying means consists in the present instance of a plurality of spools of tape 33, one spool for each seam of the cloth, and all of said spools being preferably mounted at the receiving end of the machine upon the spindle 34 as will be apparent.

In. view of the fact that the tape-applying means as well as the treatment of the tapes by the adhesive is similar for each tape, the description will be limited to the mechanism for one tape, butwill be understood as applying to all. 35 designates a tubular guide suitably fixed to the frame 1 and having one end positioned adjacent the spool 33 to receive the tape while its opposite end is located adjacent the adhesive applying means. I

The adhesive applying means consists,

in the present instance, of a receptacle or trough 36 suspended at opposite ends from the rods 37 which are fixed at one end to a slidable block 38 and are suitably supported for sliding movement in the frame 1. The block 38 also carries a rotatable spindle 39 disposed between the rods 37 and carrying the applying roll 40 which is so positioned as to be partly submerged in the cement or adhesive 41. The cement or adhesive in the receptacle is kept in suitable viscous condition by means of a gas burner 42 located in operative relation to the receptacle 36. The tape 43, after leaving the guide 35, passes over a series of rolls 44 into contact with the roll 40 and thence to device for pressing it to the material. The rolls 44 are mounted upon a frame 45 pivoted upon one of the rods 37 and is adapted to be moved from one position to another by means of the hand lever 46 which operates upon the proper rod 37. In normal op erative position of the frame 45 the tape is maintained in contact with a portion of the periphery of the applying roll 40, as shown in Fig. 6, while in its inoperative position the frame is tilted to the dotted line position of Fig. 6 wherein the tape is removed from the said roll 40.

From the discharge end of the frame 45 the tape passes between the rolls 47 and 48, the former being rotatably mounted below the table but so positioned as to feed the tape through an opening 49 in the table and into contact with the seam of the material. The upper roll 48 is similar in construction and operation to the pressing rolls '27, and further description thereof is therefore deemed unnecessary.

The first pair of rolls 47 and 48 serve to press the tape into position across the seam of the material and after which the material passes across the face of a box 50 which has one surface projecting through the top 15 into contact with the cloth and is heated by steam from the supply pipes 51. In the preferred form of the invention I have shown a second pair of pressing rolls 51 and 52 at the other end of the drying box 50, and beyond these pressing rolls is a second drying box 50 so that after the tape is applied to the seam it is alternately pressed and dried as Will be understood.

Referring again to the adhesive applying devices, it will be noted by reference to Fi s. 1 and 3, that I have provided a means or adjusting the tape and the adhesive adjuncts transversely of the machine so as to insure the tape being properly alined with respect to the moving seam. In this construction 53 designates an arm connected by the bar 54 with the block 38 and having at its outer free end the pointer 55 which serves to locate the exact position of the seam. The block 38 is provided with a rack 56 in mesh with the gear 57 which is fixedly supported on the frame 1 and rotated by means of the pinion 58 carried by the rod the- 59, this latte extending to a convenient point of oper tion where it terminates in the hand wheel 60.

It will thus be apparent by rotating the hand wheel 60 that motion will be transmitted to the rods 37 and 39 thereby shifting the tape, together with theapplying mechanism, to one slde of the other, whereby the tape is properly alined with the seam. In connection with the rod 39 it will be noted by reference to Fig. 1 that it is rotatable and driven by means of a belt 61 from the driving shaft 10 and thus actuates the roll 40 to continuously bring a fresh supply of 'adhesive liquid into contact with the tape.

62 designates a scraper fixed to the frame 45 and so positioned as to normally contact with the tape to remove any excess of the adhesive, while its opposite end rests against the roll 40 and serves to prevent the adllliesive drying and collecting upon the ro The main driving shaft 10 also transmits motion to the shaft 63 for the presser rolls 47 and to the shaft 64 for the presser rolls 51, through the medium of the driving chains 65 and 66, both of which operate about sprockets upon the shaft 10, as will be understood. A separate chain drive 67 is employed between the shaft 64 and shaft 68 to transmit movement from the former to the latter and thus operate the conveyors 25.

In the operation of the machine the rug or carpet,, formed in sections joined by seams, is positioned upon the receiving board 2 beneath the roll 3 and has its end attached to the conveyers 6. These latter being in operation, feed the rug into engagement with the main conveyers 25 and at the same time stretch the rug laterally in a manner to open up the seams to the extent of bringing the rug sections into the same plane and eliminating the ridge seam. This stretching action is materially assisted by the heated steam jets from the pipe 21 which soften the seam so that it is more readily adapted to receive the reinforcing strip of tape which is to be applied. It will be understood -that if the seams are not properly alined with the steam jet openings 21, the

latter may be brought to proper operative position by sliding the pipe 21 transversely of the machinein the required direction until the pointer 24 indicates that the parts have reached proper operative position. After the stretching action and as the rug is moved forwardly by the conveyor 25, the seams are respectively pressed by the rolls 27 preparatory to receiving the reinforclng tape.

When the rug reaches the rolls 4 and 48 it encounters the tape one side of which has been coated with the adhesive liquid. The action of'the rolls 47 and 48 is to press the tape over the seam and closely bind the two materials together. This pressing and feed ing operation of the tape and rug take place simultaneously and continuously and the rug passes from these rolls to bring the taped portions over the heating boxes 50 which initially dry the adhesive thus fastening the tape 1n fixed position. From these heating boxes the seams of the rug againpass through sets of pressing rolls and are then again subjected to the drying action from the second set of heating boxes 50. The action, as will be noted, is one of alternately pressing and heating the taped seams so that when the rug finally leaves, the machine the seam is effectively covered and reinforced by a binding tape which is made fast by the adhesive which is set during the drying and pressing operations. In Fig. 8 is shown a section through one of the rug seams wherein 69 designates the abutting rug sections joined by the seam 70 which is reinforced and covered by the permanently attached tape 71. It will be noted that the seam ridge is entirely eliminated while any tendency of the seam to open up is efi'ectiially prevented by the binding action of the tape.
