chine disclosed in the, patent to Had'awayx 29', 1898. This ma vertical slide 13 in Fig. 3 andfbroken away, in Fig. 1. The

usual insidejformer which is supported upon one arm of a bell crank indicated at 17 is caused to yieldingly engage with the inner side of the lip through the provision of the spring 18, thestem of the former being shown broken away at 19, Fig. 1.- T he forming members cooperate in the usual'fmanmg fabric about thelip of the insole, all

as fully described in the Ha daway patent her'einbe'forepreferred to. y I

It is highly desirable in this type of machine that the reinforcing fabric shall be severed cleanly along'a line conformingto ner to feed the Work and shape the r'ein'for'cthe general contour o-f the insole and in such a manner shall not'show after the insole is incorporated in a boot or shoe. fTo this'e'nd the fabric is severed, after it has been laid upon the feather by the forming tools; along'a line which is spaced a' uniform" distance from the base of the lip and slightlylwithin the" edge of the insole. 'The trimmingof that the edge ofthej' fabric the fabric s' 'accomplished by a stationary drag'knife which engages and cuts the fab Lric during the feeding of the insole, a vpresser foot which rests upon. the feather of the insole controlling the-depth "ofrut. For thispurpose, a drag knife'20.is fpi' o- ,vided, being received in a knife block 21 pivoted upon'a fixed bracket 22. The knife block 21 is provided Withan r mped lower end 25 having one portion extending substantially in the line of feed at'the side of y the knife and a second portion at right angles thereto extending across the line of feed which rests upon the face of the insole and acts as a presser foot to gage the depth of cut made by the knife. This lower portion of the knife block is curved deflecting, surface 26; which serves to direct the severed portion of the fabric out of the machine. pivoted upon a fixed stud 28 clamped at one end in a split hub 29 formed upon the bracket 22, a clamping screw 30 serving to draw the two parts of the hub together and bind the stud in position. The hub portion of the knife block 21 is provided with an upwardly extending taii 31 which carries an adjusting screw 32 adapted to limit the downward movement of the free end of the knife block through contact. with the opposing face-of the bracket 22", as shown clearly in Figs. 1 and 4. The knife block and knife carried thereby are normally pressed into engagement with the work by a plunger 35 slidingly received within the bracket 22' and engaging with the upper face of the knife block a spring 36 serving to apply the requisite pres- Sure to the plunger. It will be noted that this bracket 22" conveniently carries the stationary outside former 15 which is adjustiably fastened thereto through a screw and slot connection, indicatedat 37. The stationary bracket 22 is connected to a. depending portion 38 of the machine frame through tongue and groove connections 40 and a clamping screw 41, as shown in Figs. 2' and 3, thus affording provision for a transverse adjustment of the knife and stationary former across the line of feed. In order to adjust the depth of cut made by the knife for varying thicknesses of reinforcing fabric or other reasons, the knife is provided with rack teeth 42 on the under edge which are engaged by a single toothed adjusting pinion 43, the side of which has a slot, as shown in Fig. l i,.into which a screw driver or other tool may be inserted for rotating the pinion. The knife is clamped in adjusted position in the knife. block by the head of a clamping screw 44. With this construction it will be noted that the trinnning knife cuts-to a measured depth predetermined by the relation of the knife and presses-foot both of which are yieldinglypressed against the work with sufficient pressure to properly maintain the presser foot in contact with the'surface' of the feather. In order't'o' prevent injury to the knife if the machine is operated without an insole located. upon the table, the latter is provided with a peripheral groove 4L6 positioned beneath the knife and into which the knife. may enter when the table rises under the influence of its spring; The screw 32 is so adjusted as to permit the knife to be yieldingly held against the sole while trimming the reinforce and,

provided with a The knife blockisinsoles having,

therefore, the presser foot may extend. to a position slightly below the lower end of the stationary former l5.

It will be recognized by those skilled in the art that the canvas trimming feature of the machine herein describedis not limited in its use to a combination with head forming instrumentalities, but will perform for operating on, previously reinforced soles.

While it is preferred to employ the specific' construction and arrangen'ie'nt of parts shown and described, it will be" understood that this construction and arrangement is not essential except so far as specified in the claims, and may be changed or modified without departing from the broader features of the invention.
