To allwhom tame concern: i 1

Be it known that I, THOMAS II. SEELY, a citizen of the United States, residing at Dorchester, Boston, in the county of Suffolk and State of .Massachusetts, have invented certain new and useful Improvements in Insole-Reinforcing Machines; and I do hereby declare the following'to be a full, clear, and exact description of the'inventio'n, such as will enable others skilled in the art to which itapp'ertains' to make and use the same. I

This invention relates to machines for ap-j plying reinforcing material to lnsoles WhlOll' are used in the manufacture of boots'and shoes, and more particularly to mechanism for trimming thexcess reinforcing material while it is beingapplied to the insole.

Heretofore, in using machines of the character referred to, the reinforcing material has been formedabout the lip and applied along the marginof the insole, step by step, and as the insole progresses through the machine cutters, guided by the contour of the insole, triin the reinforcing material along a line coinciding with its edge. One such machine is thatillustrated and described in the United States patent to J .B. Hadaway No. engseo, dated November 29, 1898. After the insole is reinforced and the fabric is trimmed in the manner described in said patent the edge of the reinforcing material oftenbecoines loosened from the featherand its edge ravele'd out so that the threads of the fabric show beyond the edge of the hi sole when viewed from its grain side." This condition is undesirable as it renderstheiii sole unsightly and detracts from its selling qualities, "The object of the present invention is to improve the fabric trimming mechanism so as to overcome the disadvantages heretofore experienced in trimming the fabric along the edge of the feather.

In accordance with this object, the inventioii contemplates the provision, in a machine of the character deseribed in; said Hadaway patent heieinb'efore referred to, of rotary eel-ramm ng knives! qonsauee ed anoint-ranged seas totsever the fabrie along a line within the edgelof the insole instead of coincident with said edge.

construction and arrangement of theiropei'rating mechanism so asfto effect a severance of the fabric along line spaced from the edge of the insole! I d The various features of the inventionwill be best understood from an inspection bf the accompanying drawings illustrating the preferred embodiment of the invention, in which s Figure 1, is a side elevation of the machine" looking from the right and has parts about the trimming knives removed in order to show the improved trimming knives; Fig. 2 is a detail view showing the relation of the trimming knivesto the insole during the trimming operation and Fig. 3 is a front el'evation'of theparts shown in Fig. 2; I The preferredenibodiment of the invention is illustrated as applied to the insole r'e mforcing machine shown in the patent to Hadaway Ne. 614,860 hereinbefore referred to, and reference maybe had to this patent fora detailed description of the machine and its mode of operation. As described in said patent, head frame A mounted on a base A carries the reinforcing tools and their operating mechanism; In this frame is also mounted a work support 0 which is held vieldingl in workingposition. An inso'le having a piece of reinforcing fabric reughlv applied to its lipped face is placed upon the support C, which may be lowered through-means of a treadle attached to b with its lip againstthe beading finger e of the formerE. Theprojeeting margin of the reinforeing material rests on the top of the beading finger. When in operating posit'ijen the insele is clamped between the suppo'i't C and a bead forming tool which bears upon the ieinforcing material on the feather of the insole. Rotation of the main cam shaft B forces the presser tool D against the reinforcing material upon the face of the in, sole mean of its connection With cam b? and; tacks the material against the inner fact of the lip. From this point a forming tee-1 F forced downwardly thtou'ghthe medium of cam 5 andby coeperation with a finger pressesuie reinforcing'niaterial down along the outer side ofthe lip cont plet'ing' the formation of abead or crimp about thelip, while the stationary forming tool behind the forming tool F presses the feinfo'rcin material down upon h the feather The rain h 'carrie's' a cam which is connected with the lever 0 and this lever actuates a pawl for rotating the support G step by step so that after the material has been pressed down upon the insole the presser tool D is raised releasing the insole and a slide f moves the forming tool, F forward simultaneously while the support 0 is rotated by the pawl 0 After the'tool F has finished its forward stroke it is raised and returned to its former position ready to repeat its operation on the insole preparatory to making another step.

i and preferably are,

All ,of the parts just described may be, substantially the same as the corresponding parts in the Hadaway patent. I

The trimming mechanism to remove the excess reinforcing material from the edge of the insole, which forms the subject matter of the presentinvention, comprising the rotary ,disk cutters m, m and their operating mechanism, is mounted in the rear of the support C and as the insole with the reinforcing material attached thereto is fed forward the knives sever this excess mate-. rial. The cutter m is carried upon the forward end of; the shaft 2, andthecutter m" upon the forward, end of ashaft 3, these two shafts being mountedv in suitable bearings in a carriage 4. The carriage 4 is in the form of a yoke the twofarms of which afford a double bearing for both of 'theshafts. yThe shafts 2 and 3 'are rotated simultaneously in opposite-directions by means of a. pinion 13 mounted'upon the driving shaft 3 and meshing with. a

similar pinion on the'driven shaft 2. The shaft 3is extended rearwardlybeyond the carriage4 and has a lateral lug 5 carried by its outer end which isengaged by an actuating arm 6 attached'to the inner end of a stud shaft Smounted in abearing 9. The bearing 9 is carried by'a standard 10 whichis attached to the head A. by means of a block 30 and bolt 31. The shaft 8 is driven by a belt-pulley 11. Rotation of the shaft 8 will impart rotation vto the shaft 3 by means of the coupling 5- 6 and the shaft will be rotated in the oppositedirection from 3 through the medium of the pinions 13 and12.

- .The irregular contour of an insolerequires that the trimming mechanism shall be capable of a longitudinal movement so that itwill follow the edge of the insole in trimmingoif the reinforcing material. The carriage 4. is mounted to move freely back and forth toward the support C upon a bar 17 which is pivotally connected at 18 to a pair 7 of swinging levers 19 that. are fulcrumed at 20. to the head A. vThe inner end of the carriage 4 is adjustably connected to the bar 17 by means of a slotted sup.- porting arm 32 and set screw 33 which will allow for adjustment toward and away carriage is rigidly connected to the bar 17 by means of the supporting arm 34. This mounting of the carriage 4 upon the bar' 17 is such that the outer ends of the shafts 23 arethrown' away from the head A and are raised above the plane of the support 0 so that the shafts are caused to extend'at an angle to the support C (see Fig. 1). This causes the knife m" to be located above the feather and inside of the edgeofthe insole and the knife m to be located below it in a position to chamfer the edgeof the insole when. the knives are operated. Consequently the reinforcing fabric is severed along aline inside of the edge of the insole.

One of'thelevers 19 has a projecting arm 21* which is arranged to have a :limited movement between the; adjustable stop screws 22threaded in bearings in the lugs 23 on the frameA, and said arm 21 is connected to one end ofa spring 24 the opposite end of whichis secured in one, of the lugs, 23. The forward bearing for the lever shaft 3 is squared-and has secured thereto a guard frame 25 (Figs. 2 and 3) which is provided with a portion 26 extending over the shaft 3, forming atable over which'the marginal portion of the canvas travels as the insole is fed forward. The free end of this bearing has mounted thereon a sole gage '27. shown best in Fig; 3,'just in advance of the cutters and opposite their bite. This gage, as is seen, is mounted for adjustment toward the cutters as they wear smaller. The gage 27 prevents the cutters from cutting" in too deep, the size of the beveled string chamfered off being determined by a longitudinal adjustment of the guard 25 on the shaft journal. In order to adapt the trimming mechanism for different thicknesses of insoles, the fulcrum -20 of the inner lever 19 is eccentrically mounted upon the frame A and when the adjust ment hasbeen made to determine the verti-. cal position of the knives m and m the positionof the eccentric fulcrum 20 is secured by means of aset screw 35. I I That the cutting knives m and m/may be kept in proper adjustment and in close contact while traveling along the edge of the insole, the shaft 2 is arranged to have a longitudinal sliding movement in its-bearings in the carriage 4.; Surrounding. this shaft is a coiled spring; 14 which .bears against the inner end of the yokeof the carriage 4, and at its opposite end against ,a collar 15 secured upon a shaft 2 so that from the head A, and the outer end of the nism, the gage 27 will be held against the upper edge of the insole by the spring 24, while the knife we will be held by the spring 15 in close contact with the knife m. The spring 524 permits the gage 27 to move in and out in accordance with the width of the feather performing the samefunction as the corresponding part on said Hadaway patent. When the insole is started through the machine the knives are dug into the upper edge of the feather, as they project beyond the gage which bears on said edge, and consequently their cutting bite is within the edge of the insole. As a result the reinforcing material is trimmed at the inner edge of the bevel produced by the knives, that is along a line inside the edge of the insole. The adjustment of the carriage 4 by means of the slotted bar 32 and the secentric pin 20 will allow for different thicknesses of feather so that the trimming mechanism is suitable for any size or style of insole.

Vhile the invention has been illustrated and described in connection with a machine for applying reinforcing fabric to insoles, it will be apparent to those skilled in the art that a rotary trimming mechanism mounted at an angle to the work support is equally well adapted to be used for retrimming the fabric after it has once been trimmed along a line coincident with the edge of the insole, and the invention is, therefore, not limited to use in a machine which initially applies the insole reinforcing material.

The nature and scope of theinvention' having been indicated and its preferred embodiment having been specifically described, what is claimed as new, is:

1. An insole machine of the character de scribed, having, in combination, means for supporting and feeding the insole and for operating on the reinforcing fabric at its marginal portion, two cooperating shear.- ing knives constructed and arranged to sever the reinforcing fabric along a line inside the edge of the feather of the insole, and means for operating said knives.
