6 Claims.
The operation of securing a heel to a shoe usually isperformed in a heeling machine which drives simultaneously all of the nails required for this purpose. At the timethis operation is *5 performed the shoe customarily is on the last on which it was made. The heeling machine ,includes gaging devices for positioning the shoe heel properly withreference to the nail plate, and also is equipped with a jack'post mechanism carrying a jack pin for entering the thimble on the last and assisting in centering the-heel end of the shoe with reference to the nail plate and the other nail driving instrumentalities. Usually, also, some additional positioning means is provided for engaging the counter portion of the shoe to aid in this centering operation. The position of the shoe during this heel attaching operation is, however, chiefly controlled by the operator. He moves the shoe in a horizontal plane into a position, largely determined by his eye, which-he regards as correct, and then operates the treadle which sets into motion the nail driving instrumentalities. V I
T The position of a heel with reference to the median plane of a shoe varies considerably in different styles of shoes. In a shoe made on a so-ca'lled straight last, the heel may line up with the shoe, or the angle of divergence between the twomay not be great, but in a very high percentage of shoes, particularly mens shoes, and more especially those made on crooked lasts or those having a decided swing, thecenter' line of the heel makes a relatively large angle with the center line of the shoe. This angle is deterthe attachment of their heels that much of the care, skill and judgment required of him will be eliminated, and the heels on successive shoes of any given size and style consequently will be positioned with a high degree of uniformity.
The nature of the invention will be readily understood from the following description when read in connection with the accompanying drawmined chiefly bythe operator and it is not an ings, and the novel features will be particularly pointed out in the appended claims.
In the drawings,
Figure 1 is a perspective view of the cone portion of a last equipped with a guiding element embodying a feature of this invention;
Fig. 2 is a side elevation, with parts in vertical section, illustrating means for positioning a shoe in a heeling machine in accordance with this invention;
Figs. 3, 4 and 5 are front, side and bottom views, respectively, of a jack post mechanism equipped with a positioning or guiding element embodying a feature of this invention;
Fig. 6 is a side elevation showing the invention applied toanother type of jack post mechanism;
Fig. '7 is a rear elevation of the jack post shown in Fig. 6; and
Figs. 8 and 9 are plan views, partly in section, illustrating other embodiments of the invention.
Referring first to Figs. 2 to 4, inclusive, the nail plateof a heeling machine of a common commercial type is shown at 2, and the jack post mechanism is indicated in general at 3. It comprises a body member having a dove-tail projection to fit into a corresponding groove in the support 4, and also includes a slide 5 in which a jack pin 6 is secured. This arrangement provides for both a backward and forward movement of the shoe, together with the pin 6 and slide 5, to 0 position the shoe for the heeling operation, and also for the swinging movement of the shoe in a horizontal plane, as above described. The heel 1 is positioned by any suitable gaging devices with equipped, so that its location with reference to the nail plate 2 and the other nail driving instrumentalities is predetermined and substantially fixed, although adjustable.
According to the present invention additional devices are provided to cooperate with each other in determining the angular position of the last in a horizontal plane, one of .these devices being mounted in the machine and the other carried by the last. In the particular arrangement i1- lustrated in Figs. 1 and 2 the forward end 'of the upper portion of the heel part of the last 8 is notched or cut away to receive a guide plate It. Preferably this plate is made of angular form in order to give added strength and to provide increased area for receiving the screws by which it is secured to the last. The guiding or positioning portion of this plate, however, consists of the upright part of it, provided with a broad, fiat. laterally disposed face extending at approximatewhich the heeling machine customarily 'is 1y right angles to the median plane of the last. In other respects this last may be of any suitable form, the particular construction shown having the usual hard fiber reinforcing plate l2 and the customary thimble I3.
The positioning element provided in the machine to cooperate with the part ill consists of a plate l4, secured to the front vertical face of the jack post body 3 by-means of screws l5. Preferably the lower portion of this plate is thickened and its rearward surface is bevelled, as shown at I6, Fig. 4, so as to provide a straight lower edge projecting somewhat behind the adjacent portions of the plate.
In using this invention, the heel I is positioned in the machine in the usual manner, and the last is slipped on to the jack post mechanism with the pin 6 inserted in the thimble l3. At this time the slide is pushed back away from the plate I4, but after the last has been placed in the relationship just described, it is then pulled forward, carrying the slide 5 and jack pin 6 with it, until the upright face of the plate it) strikes the rearward edge of the stationary positioning plate [4. This contact with the parts It) and M stops any further forward movement of the shoe, but if the plate Ill does not strike the member !4 in such a manner that the entire edge of the latter is in engagement with the former, then the forward pull on the shoe will tend to swing the shoe automatically until such engagement is produced. This swing of the shoe will take place around the axis of the pin 6, and the adjustment of the parts should be such that when the members It] and M are in full engagement with each other, the heel will be centered properly with reference to the nail plate 2. It will be evident that the full engagement of the parts Ill and M with each other can occur only when the shoe is in a predetermined angular position in a horizontal plane. In other words, these parts determine this angular position in said plane. They also cooperate with the'pin 6 to position the shoe correctly with reference to the nailing instrumentalities and the devices that position the heel 7.
Care should, of course, be taken to accurately position the last thimble 13 with reference to the shoe shaping surfaces of the last and to locate the plate It) accurately with reference to said surfaces and the thimble I3. 'These results can, however, be readily produced in a line of lasts designed for the manufacture of a given style and size of shoe. If these operations are accurately performed during the manufactureof the lasts, then the arrangement above described greatly reduces the care, skill and judgment required in positioning the shoes in the heeling machine in order to be sure that the heels on the entire line of shoes of any given style or size are correctly located.
As above stated, it frequentlyhappens that the center line of the heel makes a considerable angle with the median line of the last. The desired departures in the alinement of the parts may be made entirely by suitable changes in the position of the heel gaging devices, but this is not always possible or convenient, and in order to hold the shoe in different angular relationships to the nail plate or the heel, the plate Hl may be located in different angular relationships to the longitudinal median plane of the last. Or the same result may be obtained somewhat more conveniently by making either of the members I!) or M thicker at one side than the other. Such an arrangement is illustrated in Fig. 8 in which the part I8 corresponds to the plate In and is made wedge-shaped, or thicker at one edge than the other, so that when it is in full engagement with the edge of the plate l4, it throws the median plane of the last 8 into a divergent position with reference to a vertical plane at right angles to the plate l4.
Another embodiment of the invention is illustrated in Fig. 9 in which the cooperating positioning members, instead of having straight or flat abutting surfaces, are made of angular formation. As shown in this figure the plate IE) has been replaced with a V-shaped plate 20 designed to fit into a complemental V-shaped notch 2| in the fixture I 4', the latter member corresponding functionally to the fixture I 4. This angular shape of the cooperating surfaces 20 and 2! is of assistance in centering the guiding element on the plate properly in the stationary fixture or guiding member secured to the machine, and thus correctly locating the shoe.
In that type of heeling machine in which the shoe is supported in an inverted position during the heeling operation, the same guiding members IE3 and I4 may be used, as illustrated in Fig. 6. In this arrangement the plate In is secured to the last exactly as in the construction shown in Figs. 1 and 2. The jack post structure, however, is of a slightly different form, including a body mem ber 22 having a concave upper surface to receive a rocking and sliding block 23 to which the jack pin 24 is secured. This is a jack post mechanism in common commercial use. The positioning plate or fixture I4 is secured to the member 22 in essentially the same relationship as in the construction illustrated in Fig. 2 where it will be engaged by the plate ID on the last when the shoe is moved forward to position it for the heeling operation. It will be understood that in this type of heeling machine the nail plate and the heel positioning devices are located above the shoe, and the nails are driven downwardly through the heel instead of upwardly, as in the construction previously described. The shoe positioning operations, however, are performed in the same manner in this machine as in that shown in Fig. 2.
While I have herein shown and described typical embodiments of my invention, it will be understood that the invention may be embodied in other forms without departing from the spirit or scope thereof.
Having thus described my invention, what I desire to claim as new is:
1. A shoe last having a thimble to receive a jack pin, a lateral surface of the upper portion of the heel part of the last being provided withv a horizontally extending recess, said recess having walls located at an angle to each other, and a metal plate secured to said last and having surfaces fitting against said walls of said recess.
2. A shoe last having a thimble to receive a jack pin, a lateral surface of the upper portion of the heel part of the last being provided with a horizontally extending recess, said recess having walls located at an angle to each other, an angular metal plate located in said recess and having an approximately horizontal flange fitting against one of said walls and an approximately vertical flange fitting against the other, and means securing said metal plate to the heel part of the last.
3. A shoe last having a thimble to receive a jack pin, a lateral surface of the upper portion of the heel part of the last being provided with a horizontally extending recess in the forward end of the upper part oi? the heel portion of said last, and a flanged metal plate mounted in said recess and secured to the heel part of the last.
