secured together means of amodified methodf atively receive and support certain tie materials and structural elements of the machines as will bev hereinafter setforth. v v Y b p The base plate I'd, overlying a substantial por-'- tion of the table, slidably supports thereover, the plate Hi, the guides 16 (see Figure 8) limiting the operative movement of said; plate IE to a'forwardly andrearwardly direction. Said plate I5 is provided with a handle I! adapted to be manum ally grasped for operatively manipulating the table in a manner to be'hereinafterset forth.

The forward part of this structure contains a plu X rality of gauge elements suitably secured :to g

theupper surface ill of the'plate,l5 by means of screw; bolts l9. These elements are arran'gedacj l "ngs the main table of the machine of this invention, designated I'll, is supported by legs H. The top: ofsaid table has, in the form of my'invention-shown, three levels, the high or upper level [2, the intermediate level '13, and the lower level 9, said levelsbeing adaptedto opercording to a-predetermined setting to conformw with the outline of aselected pattern: of; tie; as is clearlyshown in Figure 8. The rearward portion of the table is provided with another set vof gauge elements 253 secured to plate H! by means of screw; bolts 2 i'. Positioned intermediate certain'of said gauges 20 are the springclipsll yieldably engageab-le with the upper surface of-plate l4.

Pivotally secured at 23 to the bracket structures 24 are the body portions of a plurality of stapling machines 25, preferably of conventional structure, each containing a staple magazine 26, a plunger 21, a knob 28,21. base 29 and anvil 3G. The bases of thesemachines are suitably supported by the longitudinal structural members 3!, 32 and 33, and their connecting parts. As in most conventional stapling machines, the upper body portions thereof are yieldably held in spaced. relation to the anvil, as clearly shown in Figure 3. It will be noted that the base plate I4 is provided with apertured portions 34 to expose the anvil of each machine to the action of its plunger whereby a driven staple can come into operative engagement therewith.

In overlying relation to the'knobs 38 of the row of stapling machines is the beam 35 having secured to the undersurface thereof a plurality of Y resilient members 36 each of said members being adapted. to engage the. underlying knob, in a manner to be hereinafter set forth. Suitably connected to said beam 35 are the arms 31 pivotally mounted at 38 of the bracket structure 39. Intermediate the terminals of each of said arms 3'! and pivotally connected thereto at 46 is the member M to which is secured the rod 42 extending through a suitable aperture in the machine to the treadle- 43 near the floor of the structure. Over each of said rods 42 is the helical spring 44 positioned between plates t5 and M5, said spring normally urging the arms}? and hence the beam 35 upwardly. Said plate 45 is suitably supported by a bracket 41 which-is secured in place by the plate 48 and bolts 49.

Pivotally attached to the lateral sides of the table are the two oppositely disposed holding strips 50, each of these being surfaced with a material of substantially high frictional coefficient. In the form shown, the strips are provided with tubular rubber casings 5|- clearly shown in Figure '7. These strips have their for- The said strips are adapted to be positioned upon ward edges of predetermined curvature to con form with the desired shape of the finished tie.

the intermediate surface 13, being the uppersurface of the plate M, the distal edges of said strips being in close proximity, and if desired, in actual abutment when the strips are placed in operative engagement and longitudinal alignment on the table, as indicated in Figure 8. It is hence seen that said strips are positioned at a level lower than the aforesaid level l2, for reasons which will hereinafter appear. The pivotal connection for each of said strips comprisesa bracket 52 suitably secured to the lateral edge of the table, and a plate member 53 pivotally secured to bracket 52, the tubular lug 54 being operatively positioned between the cars 55 and rotatably secured in place by suitable pins in conventional manner. The upper surface of said bracket is provided with a spring 56 which is in constant engagement with the undersurface of plate member 53 normallyrurging it and the parts carried thereby up wardly. Each strip 50 is suitably secured to its corresponding plate member 53 by the finger screws 51 the shanks of which extend through the size and shape of the tie, in amanner that will be more apparent from the description hereinafter given. Thus, the said strips can be slightly adjusted laterally, and forwardly and rearwardly as shown by the dot-dash lines in Figure l3,and angularly with reference to the pivotal region at the holes 58. As will be later obvious, any adjustment of said strips 5!], in either of the manners aforesaid, will have an effect upon the width and shape of the tie. It should also be observed that due to the action of said spring 56, in the normal position the said strips are retracted from the table, as shown in Figure 1.

In the operation of this device, the lining material 59 is placed upon the intermediate level or plate member 14, the rear edge 6!! of said material being placed against and in abutment with the gauge members 20. In performing this operation, the said rear edge of the lining is placed underneath the spring clips 22, which serve to hold said lining in place during the adjustment thereover of theouter material in the manner to be hereinafter set forth. It is understood that said clips 22 are merely auxiliary to this device, and not indispensable, inasmuch as other means may be employed for temporarily holding said lining in place. It will be noted particularly from Figures 4 and 7 that the lining extends forwardly from said gauge elements 20 to a portion of plate l l intermediate the stapling, machines and to gauge elements l8. Thereafter, if it is desired to employ a strip of tape for renforcing purposes, this is placed upon the lining in overlying. relation to the row of anvils of the stapling machines. It is to be understood hat the tape, or even the lining, may be dispensed with without affecting the results efiectuated by this device, if such reinforcement is not required or desired.

Thereafter the outer material 6| is placed upon the table, the forward edge 62. of which is placed against the gauge elements ill, the rear portion thereof being in overlying relation to the lining, and extending over the said anvils of the stapling machines. In Figure 8 is illustrated how the outer material 6! is placed against the gauge elements I 8, as aforesaid. It is apparent that the placing of the lining, tape and outer material can be effectuated very readily in view of the arrangement of the gauges, inasmuch as the gauge elements 20 are arranged to control the position of the lining and the gauge elements I3 to control the position of the outer material 6 I.

After the tie materials are positioned in place as above indicated, the holding strips 5|) are rought down, by manual manipulation against the action of springs 56. until they come into engagement with the tie material, as shown in Figures 4 and 8. Then the handle I! is grasped the plate l5 slidably moved rearwardly, whereupon the arcuate leading edge 63 of the plate l5 will engage the outer material 6| thereabove and fold it over the holding strips 50,-a continued movement of said plate I 5 being effecive to bring the folded-over portion of the outer material into overlapping engagement with the underlying portion thereof as shown in Figures 5 and 7. At this point the tie materials consisting, in the form illustrated, of the lining, tape and outer materials, are in their proper relative position ready to be temporarily secured together.

With the holding strips 50 being held down-in the posi ion shown in Figures 4, 5 and '7, the treadle 43 is depressed, causing a consequent deall? 'pression of the rods 42 and the beam 35 against the action of springs M. The downward movement of beam 35 obviously carries with it the yiedable elements or equalizers 36 which come intooperative engagement .with the knobs-28 of the stapling machine, to cause an operative manipulation thereof in conventional manner. In other words, the plunger 21 is depressed,'the pivotally mounted body portion of the staple moved downwardly, and a staple forced through. two thicknesses of outer tie material, the tape and lining 59. The anvil of the stapling machine is so shaped as to cause the staple legs to be' bent outwardly, as clearly illustrated in Figures 6 and 10, the staples 85 containing the legs 66 and" 51 clenched outwardly rather than inwardly as in the more customary stapling operation. This form of clinched staple provides a'temporaryfastening means as is well known in the art where by .it can be readily removed by grasping it between the fingers and withdrawing it from the material. The yieldable elements 36 areinstrumental in causing all the stapling machines to be operatively actuated simultaneously, inasmuch as any difference in distance between the beam 35 and the knobs 28 are taken up by the compression of said equalizers or elements 36.

After the stapling operation has been completed, the holding strips 50 are released, and are obviously urged upwardly by the springs 56 to the position shown in Figure 1; whereupon the tie will assume the position shown .by dot-dash lines in this figure. Thereafter the tie is simply grasped at the middle. thereof between the terminals of the strips and slidably withdrawn from the strips.

The tie is now in reversed condition, the component parts thereof being suitably secured together by a line of staples 65 as above explained. Thereafter, the tie is taken to an operator who either performs a hand or machine sewing operation. Depending upon the method of manufacture, the staples can be removed either before, during or after the sewing operation is performed. It is preferable in the hand sewing operation for the operator to pull out the staples simultaneously with the sewing operation, which can be readily efi'ectuated without difficulty. Af.

ter the sewing operation, the tie is put througha simple reversing operation, in accordance with the various modes of practice. By means of the method hereinabove described, it is thus apparent that tie materials can be quickly folded together into their proper relative positions and in accordance with predetermined patterns. No

of temporarily fastening and holding the tie materials may be employed such as the flexible strips described in my co-pending applications, Serial No. 55,970 and Serial No. 190,174, and the pin setting apparatus described in my co-pending application, Serial No. 168,586, the method constituting the invention herein described has its own.

distinct advantages, particularly in its ease of operation, simplicity of structure and low cost.

In the slide plate I hereinabove referred to,

the leading edge 63 is shown to be of arcuate substantially the'line of! stitching contour, the preferred arrangement being such that the r'adius of curvature of edge 63 is greater than that of the forward edges of the holdingbe greater at thecentral portion of plate l5, than at the ends thereof. With such an arrangement, the end points of the plate, such as those identified bythe numerals 68, will contact the tie material and fold it over the holding strips 59 slightly before'it will contact and. fold the material at the center of the table,thereby effecting a slight plowing inwardlyv of the tie during the folding operation. This effect is considered desirable, and in any event preferable to a plowing outwardly, which would result if the aforesaid relationship of the said leading edge 63 and forward edges of the plates .50 do not exist. With an outward plowing, a point, which could be identified by thedesign element B in Figure 9, would be .moved outwardly to the position identified by BF, which would obviously produce distortion of the tie. By the inward plowing. not only is such a distortion obviated. but the row of staples is kept at thecenter of the lining which obviously is the most preferred arrange- I ment, inasmuch as the line of staples represents at the medial rear portion of the tie;

Another method'within the contemplation, of this invention for eliminating a possible outward plowing of the material is to arrange the stapling machines convexly with respect to the line curved in the reverse direction to the curve of the leading edge 63 of'plate 15. This will obviously produce a line of staples slightly along a curved path similar to that shown in Figure 14. where the curvature is illustrated asnot be ing of avery marked degree. When the staples are positioned as shown in Figure 14, it-is 'ob-' vious that there will bea corresponding rearward and inward movement of the endportions of the tie material, so that the edge E9 of the lining and the edge '19 of the. outer material will be subadaptations of the method constituting this invention can be employed beyond and in addition to that hereinbefore described, all scope of the appended claims.
