ORRELL ASHTON, OF LAWRENCE, MASSACHUSETTS, ASSIGNOR T0 UNITED SHOE MACHINERY COMPANY, OF PATERSON, NEW JERSEY, A CORPORATION 0F NEW JERSEY.

MACHINE FOR USE IN THE MANUFACTURE OF BOOTS AND SHOES.

To all whom it may concern:

`Be it known that I, ORRELL ASHTON, a citizen of the United States, residing at Lawrence, in the county of Essex and Commonwealth of Massachusetts, have invented certain Improvements in Machines .for Use in the Manufacture of Boots and Shoes, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines which are used in the manufacture of shoes and particularly welt shoes, and is herein shown as embodied in a machine that is equipped with means for removing surplus material from the shoe by trimming off the projecting edges of the vamp and lining after the shoe has been lasted, and before the inseam sewing operation.

An object of the present invention is to provide a machine by which the shoe blocking operation may be performed while another operation, such for example, as the vamp trimming operation, is being carried on. This blocking operation has for its purpose to shape the shoe, particularly the side face of the shoe at and adjacent to the edge of the shoe bottom. v

An important feature of this invention consists in mechanism for blocking a lasted shoe while the shoe is being subjected toY another operation so that no loss of time is required for the blocking operation. More particularly stated, this feature of the invention consists in the combination with a blocking or shaping tool and a tool for performing a different operation on a shoe, of connected mechanism for Vactuating the shaping tool and said other tool. AS shown, the blocking tool is a reciprocating beater arranged below a vamp trimming knife and adapted to strike the side of theshoe while the latter is in operative relation to the knife. The knife and beater are preferably arranged to operate in such time relation that the beater strikes the shoe while the latter is held by the cutters bet-Ween the advarices orrfeeding movements of the shoe.

Another feature of the invention consists in the combination with the blocking tool Specification of Letters Patent.

and a second tool for operating on a shoe at the same time, of means under control of the workman for controlling the operation of the blocking tool independently of that of the other tool. I have herein shown the machine as equipped with means whereby the workman can render the blocking tooloperative or inoperative at any time and can vary the force of the blows delivered by the blocking tool.

The machine is provided with means for guiding the shoe and the guiding means cooperates with the blocking tool to position the shoe for the action of that tool. These guiding means include a device to engage the bottom of a welt shoe, and, by contacting with the face of the innersole and with the inner side of the lip or rib of the innersole, to position the shoe both vertically and horizontally. The engagement of the guiding device with the innersole and particularly its lateral engagement with the lip or rib assists in sustaining the shoe against the impact of the blocking tool. The guiding device is formed to permit the shoe to be tipped for varying the angle at which it is presented to receive the blows of the tool and itis also preferably driven in the direction of the feed of the shoe and assists in advancing the shoe between successive operations of the tools.

A further feat-ure of the invention consists in the combination with a blocking tool of a toolarranged for movement over the last bottom from the edge of the last inwardly preferablyT to and against the portion of the upper that stands up adjacent to the lip or shoulder of the innersole. This tool not only cooperates with t-he blocking tool to shape the edge of the shoe, but may force the upper snugly into the angle of union between the lip and the feather edge of the innersole to facilitate the formation of a tight inseam. The end face of this tool may advantageously be formed to press downwardly and inwardly into said angle the wire or other binder by which the uppers of welt slices are usually held in lasted position while awaiting the inseam sewing operation.

4The guiding and feeding device may, by its engagement with the inner side of the lip, form an abutment opposed to the tool which engages the upper at the outer side of the lip and coperating therewith in creasing the upper into the angle. p

These and other features of the invention, including certain details of construction and combinations of parts, will be more fully set forth in the following description and then pointed out in the claims.

Figure l is a side elevation of a machine embodying this invention; .Fig 2 is aplan view; Fig. 3 shows a modified arrangementof the blocking tool with relation to the trimming knife and also a tool adapted to be projected over the shoe bottom in coperation with the blocking tool; Fig. 4 shows another view of the same.

The frame of the machine supports a driving shaft 2 having an eccentric embraced by a strap 4, as shown in dotted lines in Fig. 1. This strap is connected to a reciprocating bar6 thatcarries aknife 8 adjustably secured in position thereon by the bolt 10. The knife 8 cooperates with the fixed knife 12 suspended by a bracket 14 from the overhanging arm 15 of the frame and also supported by the shaft 16, which passes through it and is provided below the knife 12 with the feed roll 18. The shaft 16 is driven by a .worm gear 20, meshing with a similar gear on the shaft 22 which' is driven by abelt 24 from a pulley on the shaft 2. The feed roll is provided on its periphery with ribs, as at 25, which tend to lift the vamp or lining with which they contact into position to be acted upon by the cutters. The ribbed roll also tends to feed the shoe in the direction in which the operation is progressing. The shaft 2 is also provided with a cam 30 having in its side a groove 32, which at its inner edge is concentric with the shaft and at its outer ledge is concentric through a portion of its length, forming at 34 a drop leading to a concentric portion 36. Standing in this groove is roll 38 on a reciprocatory bar 40 that carries at its front end a blocking tool 42. Projecting laterally from the bar 40 through a slot in the frame is a stud 44 embraced by the slotted upright arm 0f an angle lever 45. This lever, which is pivoted at 46, has an opening through which extends the treadle rod 48 connected to the treadle 50. A spring 52 is interposed between the head of the rod and the upper face of the horizontal arm of the angle lever. A light spring 54 connects the rear side of the angle lever with the frame and holds this lever rocked backwardly with the roll 38 normally against the concentric inner wall of the cam groove. `W hen the roll is in this position the blocking hammer remains at rest while the trimming knifey 8 is reciprocated. By depressing the Vtreadle 50 the roll 38 is forced against the outer wall of t-he groove and as the high point 34 Vpasses the roll the blocking hammer is actuated toward the shoe with a force dependent uponthe extent to which the spring 52 has been compressed. By depressing the treadle and compressing the spring 52 more or less the strength of the blows of the hammer can bevaried during the trimming operation and entirely independent of that operation.

In the use Vof the machine the workman presents the shoe in' the position shown in Fig.A 1 with the face of the innersole against the lowerf end of the feed roll 18 and preferably with the inner face of the lip 55 against the periphery of the roll. Bythe reciprocation of the knife 8the projecting edges of the vamp and lining are trimmed as shown. The treadle 50 may be depressed to start the blocking hammer either when the shoe is lirstinserted so that the blocking operation will begin atthe'point where the trimming beginsor the treadle may be depressed later in theV trimming operation to cause the blocking operation to begin at any desired point. The pressureon the treadle may be varied to cause more or less severe beating of the shoe to be effected and the strength of the blows may be increased or diminished according to the requirements of each particular portion of the shoe. While the feed roll has a tendenc to advance the work in thedirection in w ich the operation is progressing the workman holdingl the shoe in his hands controls the rate atwhich the shoe is advanced and can hold the shoe stationary at any particular point while the blocking hammer thoroughly beats the upper on the side of the shoe at any places that require special treatment. In this way wrinkles or inequalities in the side of the shoe can be quickly beaten out.

It is to be observed that the blocking hammer is formed on its outer acting face to engage the side of the shoe at and adjacent to vits edge and preferably the hammer extends slightly above the edge of the shoe and also extends downwardly along the side of the shoe `for some distance. The roll 18 is formed as a truncated cone having its smaller end in position to contact with the insole and constitutes a rest about which the shoe may be tipped to vary the presentation of the shoe according tothe contour of the particular portion Vofthe shoe being blocked.

In Figs. 1 and 2 the blocking hammer is mounted on a separate slide from that which carries the trimming knife 8 and is independently actuated. q

In the modified construction Yshown in Figs. 3 and 4 the blocking tool, indicated at 60, is mounted upon the knife bar 6. f In this construction the bolt 10 secures upon the bar 6 a carrier 62 in which the tool 60 is yield ingly mounted and arranged to slide forwardly and backwardly.. The tool is held in its foremost position by a spring 64 press ing against a stud 65 projecting upwardly from the blocking tool 60 through a slotin the carrier 62. In this construction it will. be understood the blocking tool is operative at all times when the trimmer is in use. A feature of this construction is that the carrier 62 is provided with an end portion 66 adapted to project outwardly beyond the blocking tool 60 when the latter is in its backwardly pressed position and to ove-rlie the marginal portion of the shoe bottom at this time. The reciprocating member 66 which thus forms a third tool in the construct-ion shown preferably projects over the shoe bottom far enough to press the vamp against the outer face of the lip 55 of the innersole. The lip abuts on its opposite side against the feed roll 18 and the member 66 therefore serves to crease the upper material into the angle between the feather edge of the innersole and the outer face of the lip and to beat the upper against said outer face of the lip, while the roll 18 forms an abutment for the inner face of the lip. When the vampl is boundl in position by a wire 68, as is usual, the member G6, which for the purpose of identification will be called the creasing tool, serves to force or beat the wire into holding position. Tov this end it is formed with an inclined face at 69 to crowd the binder downwardly and inwardly into position to hold the upper in the angle between the lip and feather edge of the innersole. By forcing the upper snugly into the angle a tighter inseam can be formed in the subsequent inseam sewing operation. Obviously the blocking tool 60 with the creasing tool 66 arranged relatively thereto, as just described, may be mounted on a slide separate from the knife, as, for example, in place of the blocking tool 42, or these blocking and creasing tools may be used with a tool other than a vamp trimming knife, or may be used independently of any other tool.

The machine may be equipped with an upper bending device, shown at 70. In Figs. 1 and 2 the vamp bending device is adjusted, by its slot connection with the clamping bolt 10, into a retracted position while in Figs. 3 and Il it occupies its operative position.- As shown in these latter figures, the bending device is adapted to turn the upper from an outwardly flaring position into an upright position to facilitate the trimming operation.

The novel features of the above described construction shown in Figs. 3 and 4 of the drawings are not claimed herein, forming the subject matter of a co-pending divisional application, Ser. No. 657,185, filed Oct. 27, 1911.
