MACHINE FOR MOUNTING SHOES ON LASTS.

Application filed July 16, 191 7 SerialNo. 180,861.

To all whom it ma'y conoe m Be it knownthat 1, CHARLES 0. Non- MA'NDY, a citizen of the United States, residing at Maiden, in thecounty of Middlesex and State of lliassachusetts, have invented certain Improvements in Machines for Mounting Shoes on Lasts, of which the following description in connection with the accompanying drawings, is a specification, like reference characters onthe drawings indicating like parts in the several figures.

T his invention relates to machines for use in the manufacture of boots and shoes for mounting shoes on lasts. Since machines of this class are of particular utility in the manufacture of turn shoes, the invention is herein illustrated and described init-s ap;

plication to the manufacture of shoes of this type; but it will be evident that in various aspects the invention involves novel features of utility irrespective of the particular type'of the shoe. i

. lnthe manufacture of turn shoes the shoe is nrst lasted with the materials wrong side out, after which the last is removed, the shoe is turned topresent the materials right side out and the last is again inserted. Since the final shape of the shoe depends, in large measure, upon operations subsequent to the re-insertion oi": the last, it is important that the last be fully inserted in the shoe and seated firmly against the heel seat portion 01": the sole; lit has been the practice heretofore for the operator, after forcing the. last into the shoe as far as'possible by hand, usually with. the aid of some tool such as a shoe horn, to strike several blows upon the top of the last while holding the shoe and the last in one hand, in order to set the last in the shoe and iforce it :lirinly against the heel seat. It is also the usual practice, after the in sertion of the last in the shoe, to beat the heel seat portion of the sole in order to contorm it to the contour of the bottom of the last, and this operation likewise is frequently performed by the use of a hand tool.

It, is an obje-ii-t of this invention to proshoe.

last.

vide a machine by the use of which lasts may be firmly seated in shoes in a rapid, effective and uniform manner With compare tively little exertion on the part of the operator. To this end, a feature of the invention consists in an organization comprising means for imparting to a last and alshoe in which it is partially inserted a series of relative movements in a direction to force the'last firmly into the shoe. In the embodiment of the invention herein shown a'tool is provided for engagement with the top of the heel end portion of the last, together with means for imparting a series or percussional impulses to the tool in the direction of the heel seat of the shoe. The tool is so'positioned "as to enable the operator to hold the'shoe inhis hand while presenting the shoe and the last inposition to cause the last to be forced into the shoe; and in order to assist the relative movement'of the shoe and. the last at the heel portion without anydanger of wrinkling that portion of the upper which is adjacent to the heel seat, the operator will preferably clasp the upper'with one hand about of the invention is to be recognized in the combination of shoe engaging means and last engaging means with mechanism for effecting a series of relative movements of said -means to seat the last firmly 1n the It is a further object of the invention to provide means for shaping the sole of a shoe to the contour of the bottom of the To this end the invention as illustrated provides a mold for engaginga portion of the sole, with means for effecting ing a series of relative movements of the mold and the lasttoshape the sole between them. In the construction shown the mold is shaped for engagement with the heel seat portion of the sole and co-operates with a reciproratory last engaging tool which imparts to the last a series of impulses toward the mold. The construction thus affords means for simultaneously seating the last firmly in the shoe and shaping the heel seat portion of the sole to the bottom of the last, and eliminates the necessity for the usual beating of the heel seat.

The above and other features of the invention, including certain details of construction and combinations of parts, will now be described with reference to the accompanying drawings and pointed out in tlte claims.

In the drawings,

Fig. 1 is a view in side elevation of a machine in which the invention is embodied, showing a shoe and a last in position to be operated upon by the last engaging tool.

Fig. 2 is a view in front elevation of a portion of the machine including the last engaging tool, with a part of the casing removed, and c Fig. 3 is an enlarged perspective view of the shoe supporting means shown in Fig. l.

'I he machine comprises a standard 2 having bearings for a horizontal shaft 4 which is driven from a belt pulley 6 and is provided at one end with a circular holder 8 on which are mounted an annular series of rol. s 10, the holder and rolls being covered with a casing comprising a detachable part 12. Mounted for vertical reciprocatory movement in the casing is a tool 14 having a lower end portion suitably shaped for engagement with the top of the heel end portion of a last. The upper end portion of the tool 14 is arranged to be engaged by the rolls 10 to cause the rolls to impart a series of downward percussional impulses to the tool as the shaft 4 is rotated. The tool. is normally maintained by gravity with its upper end portion below the path of movement of the rolls, a stop 16 being positioned in a slot 18 in the tool to limit its downward movement. Downward impulses are imparted to the tool when it is raised into operative relation to the rolls 10 by upward pressure of a last against its lower end. An adjustable stop 20 is positioned to be engaged by a lug 22 on the tool to limit the movement of the tool toward the rolls 10 and thus determine the extent of perative movement of the tool. An additional guide for the tool 14 is provided by means of a depending casing 24 which encircles the lower portion of the tool, this casing serving also to guard against engagement of the operators hands with the tool, particularly when the machine is operating upon very small shoes. The casing 24 terminates at such a distance from the lower end of the tool as to permit effective reciprocatory movement of the tool in engagement with the last without interference between the last and the casing. 4

The machine is further provided with shoe supporting means comprising a block 26 the upper surface of which is shaped in conformity to the desired shape of the heel seat portion of the sole of the shoe, the block 26 thus constituting a mold for the heel seat. The block 26 is mounted upon a supporting plate 28, the connection between the block and the plate comprising a pin 30 on the plate which engages in a hole in the block and permits the block to be adjusted about the pin as an axis into different posi tions to suit the convenience of different operators. In order to maintain the block in adjusted position on the plate the block is provided with a curved T-slot 32 which is engaged by the head of a bolt 34 on the plate to clamp the block to the plate. The plate 28 is arranged to be lifted by means of a treadle 36 pivoted at 38 on the frame 2, the connections between the treadle and the plate including a rod 40 which is vertically movable in a bearing formed in a lug 42 on the frame, a set screw 44 being provided for engagement in a slot in the rod in order to prevent the rod from turning.

Pinned to the upper end of the rod above the lug 42 is a tubular sleeve 46 within which is received the lower end portion of a rod 48 which depends from the plate 28. Mounted to turn on an enlargement of the rod 48 above the sleeve 46 is asleeve 50 which is provided with an upper cam surface 52 inclined relatively to the axis of the rod and arranged for engagement with a correspondingly inclined surface on a sleeve member 53 which depends from the plate 28. It will be evident that with this construction turning movement of the sleeve member 50 serves, by the co-operative engagement of the respective cam surfaces of the members 50 and 53, to vary the altitude of the plate 28 and the mold 26 relatively to the rod 40, turning movement of the rod 48 relatively to the sleeve 46 being prevented by a set screw 54 which is mounted in the sleeve 46 and engages in a vertical slot in the rod 48. In order to permit adjustment of the mold to be readily effected for varying the normal distance between the mold and the tool 14 for different sizes of shoes, the member 50 is provided with a handle 56, and mounted in this handle is a spring held pawl 58 which is arranged to engage a ratchet 60 mounted on the upper end of the sleeve member 46 to maintain the parts in the desired adjusted relation. When it is desired to lower the mold relatively to the rod 40, the pawl 58 may be retracted from engagement with the ratchet 60. by means of a pin 62.

The connection between the rod to and the treadle 36 includes a spring ea which encircles the lower end portion ofthe rod and abuts at its upper end against a casing mem her 66 which is clamped to the rod and e tends downward over the spring. The low r end of the spring 64 bears upon a nut 68 which is adjustably mounted on a short sleeve member 70 vertically movable in a bearing in a lug 72 on the frame, the member 70 being connected to the treadle 36 by means of lmks 74:. A reduced lower end portion of the rod 40 extends through the sleeve 70 and is provided at its lower end with a nut 76 arranged to abut againstthe lower end of the sleeve. The spring 64 is thus held under compression between the casing 66 which is clamped on the rod a0 and the nut 68 which is mounted on the sleeve 70, the nut 7 6 serving to limit the expansion of the spring. By adjustment of the nut 68 on the sleeve 70 the tension of the spring can be Varied.

Normally the mold'26 is maintained in its lowered position with the lower end of the sleeve member 46 resting upon the upper surface of the lug 42. In order to raise the mold to its operative position the operator depresses the treadle 36, thereby elevating the rod 40 through the connections including the links 74 which co-operate with the treadle to form a toggle. When the shoe support is raised the links M and the rear portion of the treadle member36 extend in substantially parallel relation to the rod 40 and thus relieve the operator from any substantial. strain incident to downward pressure upon the shoe support. During the operation of the machine upon the work the spring 64L permits the shoe support to yield to some extent against the impulses of the operating tool.

In using the machine the operator first inserts the last in the shoe in the customary manner, forcing the heel end portion toward the bottom of the shoe as far as hecan conveniently do so by hand, usually with the aid of some suit-able tool such as a shoe horn. He then presents the shoe and the last in the position illustrated in 1 with the top of the heel portion of the last in engagement with the tool, and presses the work upwardly to cause the tool to be open ated by the rolls 10 with percussional iiupulses directed downwardly in the direction of the heel seat 01" the shoe. During this operation he preferably clasps the shoe about. the heel end as shown. in Fig. 'l to assist the operation of the tool in forcing the last into the shoe. After the last has been forced in this manner substantially into engagement with the sole at the heel seat, the operator depresses the treadle 36 and raises the mold 26 into engagement with the heel seat portion of the sole. is thus continued in position to receive the impulses of the tool let while the mold presses upwardly against the sole, and in this manner the heel seat portion of the sole is shaped between the mold and the bottom oi the last. the spring (i l serving to hold the mold against the shoe with a yielding pressure. The operator is thus enabled with a little eii'ort upon his part, to cause the last to be firmly seated in the shoe in preparation for subsequent operations upon the shoe and also to cause theheel seat to be shaped as required in conformity to the contour of the last.
