Specification of Letters Patent.
Patented J une 25, 1912.
Application filed August 5, 1910. Serial No. 575,801.
To all whom it may concern:
Be it known that I, ADAM H. PRENZEL, a citizen of the United States, and a resident of Halifax, in the county of Dauphin and State of Pennsylvania, have made cer` tain new and useful Improvements in Machines for Embossing Heels on Shoes, of which the following is a specification.
My invention relates to devices for em.- bossing heels on shoes, and it consists in the constructions, combinations and arrange# ments herein described and claimed.
An object of my invention is to provide a device which may be used advantageously in the manufacture of shoes, more especially childrens shoes, and in which the operation of making the heel may be eifected with far less labor, and in a much shorter time than heretofore.
A-further object of my invention is to provide a special form of die by means of which the embossing operation may be carried out.
Other objects and advantages will appear in the following specification and the novel features of the device will be particularly pointed out in the appended claims.
My invention is illustrated in the accom` panying drawings in which` Figure 1 shows a side view of the machine and its manner of use, Fig. 2 shows a front view of the machine, Fig. 3 is a front view of the upper die used in the embossing operation, Fig. 4 is a sectional view through the upper die along the line 4 4 of Fig. 3, Fig. 5 is a bottom plan view of the upper die, Fig. 6`is a side view of t-he lowerdie, Fig. 7 is a main view of the lower die, and Fig. 8 is a plan view of the lower die.
In carrying out my invention, I provide a main frame 1 (see Fig. 1) having journaled thereon a rotary die holder 2. This die holder may be set in various positions by tightening up, or loosening, the nuts 3. At the bottom part of the frame is an extension 4 which is bored to receive the sliding post 6. The latter carries a spring 5, which bears on the under side of the extension 4, so as to keep the post in a normally depressed positio The post 6 bears at its top an integral arm 7, which is bored out to admit the reduced portion 8 of a die supportl 9. Between the reduced portion 8 and a reduced extension 4a of the part 4 I place a spring 1Q. A guide member 11 with a l .stop nut 12 is secured to the extension 7 and 1 s arranged to pass through the part 4a for limiting the upward movement of the post 6: The die holder 9 bears on the upper portion of the part 7 and may be rotated around the axis of the reduced portion 8. It is provided with a stop pin-13 adapted to engage a stop 14 secured to the member 7. When the stop pin 13 is against the member 14, the lower die is immediately beneath the upper die. The dies used in connection with this device are best illustrated in F igs. 3-8 inclusive. The upper die is provided with a post 15 arranged to be inserted in the die holder 2. This post is integral with an upper portion 16 bearing at each end regulating set screws 17 and 18, respectively. The lower portion 19 forms the die proper. It is provided with upwardly extending portions 19a and 19b arranged to straddle the portion 16 to which it is pivoted by means of a pivot pin 20. It is apparent that the members 16 and 19 may be adjusted relatively to one another by means of the set screws 17 and 18. The bottoni part. of the die 19 is provided with a plate 21, which is secured to the member 19 by means of the screws 22. This plate is recessed at 23, and is of a heel shape. It will be noted that the recess is provided wit-h a beveled portion 23a near one end thereof, this portion being designed to form the beveled surface which connects the heel proper with the sole and which corresponds to the breast end of an ordinary heel. It will be noted that there is a beveled portion 23b extending around the edge of the recess. The beveled portion 231 operates to exert a lateral pressure upon the heel end of the sole, thereby vertically extending or thickening said edge during the embossing operation. This improves the appearance of the embossed heel and serves to give the impression that the heel is thicker than the other parts of the sole.
In Figs. 6, 7 and 8 I have shown the lower die-member 24. The lower diemem ber has a surface of a shape similar to that of the recess in the upper die member. The lower die member is somewhat smaller than the recess in the upper die member to allow for the thickness of the material coming between the die members during the embossing operation. Around the edge of the lower die member is a channel 24, The
' subject-matter of another application purpose of this channel is an important one. I have found that in the operation, which will be subsequently explained, unless this channel is provided the shoe is liable to be injured. The die 24 is recessed at- 24b (see Figs. 6 and 7 and a coiled spring 25 is disposed therein and held by means of a screw plug 26 in the bottom of the die member. The spring 25 bears on the head 27 a of a pin 27, keeping the pin normally in a raised position, such as that shown in Fig. 6. A similar pin 28 having similar means for lreep ing it above the surface of the die is provided as shown in Fig. 8. VThe diemember 24 is provided with a dovetailed slot 29 (see Fig. 7 arranged to fit a similar shaped tongue 30 on the die support 9 (see Fig. 2). This holds the die to the support. The die is further held by means of the screws 31.
From the foregoing description of the various parts of the device, the operation thereof may be readily understood. The apparatus, as stated above, is for the purpose of embossing a heel on a shoe. The process of manufacturing the shoe will be completely set forth in a subsequent application Ser. No. 575,802 of even date. The novel shoe produced by this process has been made the Serial No. 575,803 also of even date. It is only necessary in the present case to indicate the operations connected with the machine itself, which forms the subject of t-he present invention. The rotatable die support 9 with the lower die is swung to one side. A shoe is now placed over the lower die. 33, which is pivoted to the reduced portion 8a of the post 8, is now drawn downwardly by pressing a foot lever (not shown) and the support 9 with the shoe upon it is then swung back until the stop 13 engages the arm 14. The rod 33 is released and the spring 10 forces the support upwardly so that the shoe is centered by means of the beveled sides of the die. I regard this preliminary means of centering the shoe as quite important. It will be seen that if the shoe should not be placed on the lower die in exactly the proper position, it will be moved to its proper position when the arm 9 is permitted to spring upwardly, this insuring an accurate adjustment of the shoe upon the lower die, would otherwise be required for its proper adjustment. The post 6 is now forced upwardly,thereby moving. the shoe against the which upper die.- The leather of the shoe, has been previously moistened, is embossed so as to form a heel port-ion on the shoe. The pins 27 and 28 are guide pins for a pasteboard filling 34 (see dotted lines in Fig. 6) which is placed thereon. This lling is glued on its upper side and is maintained in position by means of the pins 27 and 28. When the heel is embossed, the
The rod j ing` a bore,
and saving time whichY lower die forces this filler into the recess made on the inside of the shoe. The guide pins 27 and 28 are pushed inwardly against the tension of the springs 25, but return to their position when the operation is over and the supporting arm 9 has been lowered. The arm 9 is now swung outwardly and the shoe is removed from the machine with the embossed heel and with the filler on its inner surface.
The reason why the channel 24a is provided will be readily seen from an inspection of Fig.1. This channel, it will be observed, is adjacent to the stitching, which sews the upper to the heel portion. Unless this channel is used the die is liable to cut the stitching, thereby injuring the shoe. In order to gage the depth of the portion to be embossed, I provide the adjustable set screws 17 and 18. It will be seen that by manipulating these screws the rear portion of the embossed heel, or the opposite front portion may be made higher or lower, according as the set screws are moved, the die member 19 being swung on its pivot 20.
The machine described above provides an eflicient device for embossing heels rapidly, accurately and cheaply. The dies are securely held in place and may be replaced whenever it? is necessary.
I claim 1. In a machine for embossing heels on shoes, a laterally shiftable support, a lower die mounted on said support and providedY with a heel shaped surface arranged to enter t-he inside of an inverted shoe, an upper die having a heel shaped recess larger than the heel shaped surface on the lower die, and a spring for moving said lower die and the shoe against said upper die for adjusting the position of the shoe upon the lower die, the said support being capable of further movement for embossing a heel upon said shoe.
