Patented Sept. 8 i931 UNITED STATES PATENT oer-"E FAY I). KINNEY, OF WENHAM, MASSACHUSETTS, .ASSIGNOR T0 UNITED SI-IOE MACHIN- ERY CORPORATION, OF PATERSON, NEW JERSEY A CORPORATION OF NEW JERSEY MACHINE FOR APPLYING PRESSURE T0 SHOES Application filed February 5, 1929.
This invention relates to machines for applying pressure to shoes and is herein illustrated as embodied in a machine particularly adapted to apply pressure to the upturned margin of an unvulcanized rubber sole in a zone extending around the lower portion of the upper of a lasted shoe.
In the manufacture of shoes having rubber soles which are vulcanized in place it is 10 common to apply a foxing of unvulcanized rubber along the lower margin of the lasted shoe, to apply to the bottom of'the shoe an unvulcanized rubber sole having a beveled margin which projects beyond the edge of the bottom of the shoe, and then to lay the sole by pressing it against the bottom of the shoe, bending the beveled margin of the sole up around the edge of the bottom of the shoe and pressing the upwardly bent margin againstthe foxing. It sometimes happens that the upwardly bent margin, and more particularly the upper edge thereof, is not pressed firmly into contact with the foXing during the sole laying operation, and, if it is not so pressed, a satisfactory joint between the two will not be secured when the shoe is subsequently vulcanized. In order to ensure that the upper edge of the upwardly bent margin of the sole shall be pressed securely into place, it is customary, after the sole has been laid in the manner which has been described above, to perform an additional pressing operation by hand upon the upturned margin of the sole by running a so-called stitching wheel along the edge of the up turned margin to ensure that it shall be firmly pressed at all points-and particularly along its extreme edge-against the foXing. An object of the present invention is to pro vide a machine by which this hand operation and similar pressing operations may be carried out.
According to one feature of the invention there is provided a sectional holder the sec tions of which are fastened together by a flexible member so that the holder may be caused to conform to the curves along the lower edge of a shoe, and a distensible member carried by the holder which may be distended by air or other fluid pressure to cause containing Serial No. 337,674.
pressure to be applied to the shoe. In the illustrated construction two substantially U- shaped sectional holders are provided, one for therear part of the lower margin of the shoe and one for the forepart, the sections of each holder being fastened together by a flexible steel band, and each holder containing a hollow, distensible, rubber member which may be inflated at the proper time to apply pressure to the shoe. In the operation of the machine, one of the holders is first brought into contact with the rear part of the shoe in the locality of the upturned margin of the sole and the distensible member inflated; and then this holder is withdrawn and the other holder caused to act similarly upon the forepart of the shoe.
This and other features of the invention including certain details of construction and combinations of parts will be described as embodied in an illustrated machine and pointed out in the appended claims.
Referring now to the accompanying drawlngs:
Fig. 1 is a front view, partly in elevation and partly in section, of a machine in which the present invention is embodied, and
Fig. 2 is a plan view of the machine.
The machine comprises a fiat bed or table 3 having rising from it a standard 5. Ad justably held by a set screw 7 in the upper end of the standard is a horizontal rod 9 to the outer end of which the stem 11 of a block 13 is adjustably fastened by a set screw 15, saidblock having depending from its un der side two last pins 17 adapted to enter the usual sockets formed in the top of the last of a rubber shoe 100. The shoe, shown in dot-and-dash lines, has a foxing 200 and a sole 300, the margin of the sole having been bent up, as has been described above, the line of its upper edge being indicated at 400. In order to press this upturned portion of the sole, and particularly the extreme upper portion thereof, against the sid s of the shoe-in this case against the foxing there are provided two substantially U-shaped holders indicated as a Whole at A and B each a distensible rubber tube with closed ends. 1
. at 70, carried by the table 3.
Inasmuch as the two holders and their associated parts are substantially alike, only one of them will be described in detail. The holder A consists of seven sections comprising a base section 19 and side sections 21. These sections, as best shown in Figure 2, are shaped so that they may be arranged in the general form of a U. Two flexible steel bands 23, 25, of which the band 23 is fastened to the base section 19 and threeof the side sections 21 and the band 25 is fastened to the base section and the other three side sections, hold the sections together while permitting the legs of the U-shaped holder to be moved toward and from each other. The sections of the holder are flat on their hottoms and rest upon the table 3.
In order to move the "holder A toward and from the shoe 100 as well as to open and Close the holder by swinging the legs thereof,
'the base section 19 is fast to one end of a rod 27 which is slidable in a. horizontal bore in the standard 5. To the other end of the rod are pivoted at 29 the inner ends of two arms 31, 32. The outer end of the arm 31 is pivoted at 33 to one end of a slide rod 35 the other end of which is pivoted at 37 to one end of a link 39, the other end of said link being pivoted at 11 to an ear 43 formed on one of the side sections 21 at the end of one of the legs of the U-shaped holder. The outer end of the other arm 32 is connected in a similar manner to the side section 21 at the end of the other leg of the holder by means of a slide rod 45, a link 4.7 and an car 49. Pivoted respectively to the arms 31 and 32 are the inner ends of links 51, 53, the outer ends of which are pivoted to a block which is slidable transversely of the axis of the rod 27 in a horizontal guideway formed in the upper portion of an upright arm 57, the block bein held in the guideway by plates 59. The hub of this arm has a square hole to receive a square rod 61 and is firmly fastened to the rod by dowel pins 63 and a nut 65 which is threaded upon a reduced end of the rod. This rod is slidably mounted in grooves formed in the undersides of lugs 67 69 which are rigid with the table 3 and is held in the grooves by plates 71 fastened by screws 73. Formed on the under side of the rod 61 is a rack 64 with which meshes a pinion 66 fast to a rock-shaft 68, said rock shaft being rotatable in brackets, one of which is shown Pinned t0 the outer end of the shaft is the hub of a handle 72 by which the shaft 68 may be rocked.
With this construction the U-shaped holder A will be moved away from the rear part of the shoe 100 and its legs swung apart when the shaft 68 is rocked in a direct-ion to move the slide rod 61 to the left (Fig. 1) and when later the slide rod is moved to the right to move the holder A into operative relation to ;another shoe, the base of the holder will first contact with the rear end of the shoe and then the legs of the holder will swing toward each other to cause the holder to close about the sides of the rear part of the shoe. It should be particularly noted that the links, arms and rods which connect the ends of the legs of the U-shaped holder to the reciprocatory rod 61 form an equalizing device so that right and left shoes, as well as shoes of different styles will be properly engaged by the holder.
The holder B, which is designed to extend around the forepartof the shoe, is substantially like the holder A and will not be described in detail. This holder, like the holder A, is made up of sections 119,121, fastened together by flexible steel bands 123, 125. Its
base member 119 is fast to a rod 127, which corresponds to the rod 27 of the holder A, and is connected to a slide rod 161 1) in the same manner as the rod 27' is connected to the rod 61. The links 139, 147 correspond to the links 39, 17; the slide r-ods 135, 145 correspond to the slide rods 35 and 45; and these rods are connected to the slide rod 161 by means of arms and links like the corre sponding arms and links which connect the slide rods 35 and 15 with the slide rod 61. This slide rod 161 is operated in the same manner as is the slide rod 61 by means of a rack and pinion and a handle which are like the rack 64 the pinion 66 and the handle 72. In the operation of the machine, one of the holders, for example A, is moved into operative relation to the rear part of the shoe and pressure applied to the shoe in a 11]2lIl-- ner which will presently be described; and then this holder is withdrawn and the other holder B moved into operative position and pressure applied to the shoe, the holders being of sufficient length so that the areas of the shoe upon which pressure is exerted by the respective holders overlap at the middle portion of the shoe.
Referring now more particularly to F igure 2, the manner in which the distensible members are mounted in the holders A and B will be described; and inasmuch as the mounting of each member in its holder is the same, only the mounting of the distensible member 75 in the holder A will be described in detail.
The sections 19, 21 of the holder, except the two end sections 21, each comprise a metallic shell open at both ends, the two end sections 21 being closed at their outer ends. In each section the top wall and the wall toward the shoe are cut away in the manner shown in Figure 1 with respect to the section 19; and inside each shell and forming a part of each section is a hollow lining member 77 of resilient material such as rubber. The wall of'each lining memberis partly cut away on the top and on the side toward the shoe to form a narrow slot in which the adjacent portion of the edge and upturned margin of the sole may be received, with the adjacent portion of the bottom of the sole resting upon the upper surface79 of the cut-off side wall and the adjacent portion of the upper of the shoe resting against the cut-off surface 81 of the top wall.
In order to ensure that, when the thin rubber distensible member 7 5 is inflated, no part of it shall tend to be forced in between the walls of the lining member and the adjacent portions of the shoe, the top wall of the lining member tapers downwardly to a thin edge 82, and the side wall adjacent to the sole of the shoe tapers to a thin edge 85. The two walls thus hare thin tapered ends which are forced tightly against the shoe when the distensible member is inflated so that there can be no space between the walls and the shoe into which adjacent portions of the distensible member might be forced. It will be understood that each section of the holder comprises a rubber lining member substan tially like the member 77.
The distensible member 75 is in the form of a thin rubber tube closed at both ends and may be inflated, when desired, by forcing air through a tube 83 which leads through the metallic shell and the rubber lining member of the section 19 into the distensible member. Any suitable mechanism, not shown, may be used for forcing air through the tube 83 to inflate the member 75 and for permit ting air to escape through the tube to deflate the member.
Referring briefly to the holder B, the distensible member 175 is mounted in the rub ber lining members, one of which is shown at 177 in the same manner in which the distensible member 75 is mounted in the rubber lining members of the holder A. A tube 183, which corresponds to the tube 83 of the holder A leads into the distensible member 175. It should be particularly noted that it is the rubber lining members of the sections of the holders which contact with the shoe when the holders are closed about the ends of the shoe and that, since these lining members are resilient, they will conform substantially to the curves of the portions of the shoe with which they contact.
In the operation of the machine the shoe is placed upon the pins 17 of the block 13 and located properly as to its height above the table and as to its position substantially midway between the holders by adjusting the position of the rod 9 and the block 13. One of the holders, for example the holder A, is
caused to contact with the rear end of the thereby press the upturned margin of the sole against the foxing." Air is then permitted to escape from the distensible member, the holder A withdrawn and the holder B moved into contact with the forepart of the shoe, the member 175 first distended and then permitted to contact, and the holder B withdrawn. The upturned margin'of the sole, and particularly the extreme upper portion of the margin along the edge, is thus pressed into firm contact with the foxing so that an unbroken joint between the margin of the sole and the foxing will result from the subsequent vulcanization.
Although the invention has been set forth as embodied in a machine for pressing the upturned margin of the sole into place it should be understood that the invention is not limited in the scope of its application neither to the particular machine which has been shown nor the pressing of any particular part of a shoe.
