(0142-33) Thisinvention relates to apparatus for attachv ing bottoms to shoes, and more particularly to apparatus of this type for use in cementing or otherwise adhesively attaching, leather, or other soles to shoes, boots or the like, wherein the lasted portions of shoes or the like and the soles to be secured thereto have been previously coated with an adhesive and are then subjected to pressure within the apparatus until the cement or other adhesive has set.

Various types of apparatus have heretofore been used for these general purposes, and the primary object of the present invention is to simplify and improve the construction and operation of such apparatus.

Another object of the invention is to provide apparatus of this type adapted to support the shoe or the like upon a flexible cushion during the cementing operationflche cushion being constructed to apply pressure uniformly and evenly upon the shoe bottom and around the edges of the sole or the like to be attachedto the shoe.

Still another object of the invention is to provide a handy and convenient portable half-sole cementing apparatus for use by shoe repairers as well as shoe manufacturers, for applying halfsoles to shoes.

A further object of the-invention is to provide means adapted to overlie and engage the welt of the shoe to resist the pressure of the pressure- 1 applying means against the underside of the edge of the sole, said pressure resisting means being adjustable foradaptation to cooperate with shoes of different sizes and shapes.

A still further object of the invention is to provide an apparatus having the advantages above referred to and which in addition is adapted to apply a full sole to a lasted shoe or the like, this machine being particularly adapted for use in the multiple production of shoes in the factory.

It is a still further object of the invention to provide a shoe sole attaching apparatus having a. flexible cushion or pressure-applying member wherein the pressure is exerted by a fluid such as air, water or steam.

In the accompanying drawings the invention is shown merely by way of example and in preferred form, and obviously many modifications and variations may be made therein without departing from the spirit of the invention. It is to be understood, therefore, that the invention 'is not limited to any specific form or embodiment except insofar as such limitations are specified in the appended claims. I

In the drawings, the shoe bottom'cementing machine includes a generally oval shaped hollow base I0, having foot portions ll whereby the same may rest upon any suitable surface such as a work bench or table or the like. This hollow base H in this instance includes an outwardly extending rim portion it upon which a flexible pressure-applying or. distributing member i3 such as a piece of heavy leather or the like is adapted to be superimposed, this pressure-applying member I3 being of such shape that when the same is acted uponby pressure exerting means as will be hereinafter described, the same will assume a proper "position for performing the pressure-applying operation. The outer edge ll of the pressure-applying member I3 is inthis instance secured at the outstanding rim portion l2 of the hollow'base it by means of a rim' plate l5 of general horseshoe shape as seen in Fig. 2;.or of general oval shape as seen in Fig. 6. The rim plate l5 in each instance is adapted to be secured to the hollow base portion III by means of belts or the like I! which extend through aligned holes in the rim plate l5 and the rim portion i2, the outer edge of the pressure-applying member B being thus securely plate and the rim of the base member ID.

One defect of prior constructions adapted forv stitute a true pressure-applying medium in contradistinction to air cushions or pillows as heretoi'ore used, and for the present purposes I pro; vide within the hollow base portion Ill an annu-'- lar'inflatable pressure exerting member 18 extending around the inner walls of the hollow base portion Ill, this inflatable member l8 being equipped with a suitable air or other fluid inlet valveis the stem 2|! of which extends through a hole 2i provided'preferably at the front 01 the hollow base III. 1 l

A shoe or the like 22, upon which a halt-sole is to beattached as seenin Figs. 1 to 4 inclusive, is first equipped with a'lastll and is then placed upon the pressure-applying member 12, the device in the figures referred to being constructed so that the sole portion oi the shoeoccupies a. position substantially at;the "center 01 the pressure-applying member. To hold the shoe tight- 1y down against the pressure-applying member, means are provided to cooperate with the latter, thesemeansinthepresentinstanceincludinga reacharm 24 pivotally mounted at2;i between lugs 26 and 21 uprising Irom'the rim plate II. Thisreachai-m24hassecuredtheretoadepending abutment member 21, thisabutmt member 21 having a generally rounded base 22,

The undersideor the base portion 24 or the abutment-21 is preferably provided with a layer of felt or other cushioning means II to prevent injury to,the' M84201 theshoewith which the bottom of the member is 8 88!!- To hold the shoe in proper position'during the pressure-applying operation, the rearward 'portion of thereach arm '24 is provided with a depending lug 32 pivotally mounted on the reach arm-as seen at 32, in substantially the same .mannerin whichthe member 21 is mounted on said reach arm, the depending lug 22 being adaptedtobepivotallysecuredatanyone of a plurality'oiapertures 24 at the rear of the reach arm, This lug I2 is adapted to rest within a- -suitable recess provided above the heel portion oi the last 22 as indicated at 25.

The reach arm with its abutment member 21 and depending lug 22 is adapted to press the shoe 22 firmly down against the pressure-applying member it, which shoe 22, as will.be understood, has previously had a half-sole or the like 28 adhesively applied thereto. To hold the reach arm flrmly in-the pressure-applying position, a yoke arm 21,-- pivotallymounted between lugs 28, up-

rising from the rearward part of therim plate I5,

is adapted to have its upper portion engage in one of a plurality of notches 40 provided at the extreme rearward edge of the reach arm 24.

The shoe which is to have a sole cemented thereto having been positioned as already Bescribed, the reach arm 24 is depressed to place the shoe' in the pressure-applying position, and the reach arm'24 is secured in such position by engagement of the yoke arm 31 with an appropriate notch 40.

preferably of such number as to correspond with the normal speed or the workman-in placing the shoes upon and removing them iron the devices 42 so that the cementing operation will be completed during the period or a complete revolution oi. the table 44. j

The embodiment illustrated in Figs. 8 to 10,

' inclusive, is substantially like that shown in Figs.

5 and 6-, but in addition is equipped with means Ior'overlying the welt of the shoe to resist the pressure applied to the edg of the sole, thereby not only insuring the proper application of pressure to this portion of the sole, but also preventthe pressure. 7

' This supplementary pressure resisting means comprises a holder 5. provided at opposite ds with upstanding yokes 5| adapted to be secured to the reach arm 24 by 'means'of bolts 52 passing through aligned apertures intheyokes II andtbe reach arm 24. The holder 52 is-iormed on oppo- 1 ing the said edges from turning upwardly under site sideswithaseriesoi'slotsil,the-purposeot Air (or whatever pressure ex- 5 .erting fluid is being used) is then admitted to the which will be hereinafter set forth. This holder 50 is adapted to support a plurality of members 55, which go to make up a substantially U-shaped segmental ring (see Fig. 9) the members 55 being suspended from the holder 56 each by a jointed link 56, so formed and arranged as to project laterally from the holder 50 to span the toe portion of a shoe and being adjustable vertically, horizontally, and laterally so as to cooperate with 10 shoes of difierent sizes and shapes.

The links 56 comprise each a main portion 51 formed on one end with a shoulder 58 from which there projects a stud 59. The stud 59 is adapted to be passed through one of the slots 53 in the holder 50 until the shoulder 58 engages the under side of the holder 50, in which position the por- -tion 51 is held by a wing nut 60 screwed on the stud 53. The other end of theportion-51 is formed with a hollow boss 6|, which serves as a bearing for a studded boss 62 clamped therein by a wing nut 63. The boss 62 is formed with a screwthreaded aperture 64 adapted to receive the threaded end of a stud 65 formed on the member 55.

As already stated, the construction and manher of attachment of the links 56 are such that the members 55 may be adjusted vertically, horizontally, and laterally so as to cooperate with shoes of difierent sizes and shapes. Since the adjustments which may be made are the same in the case of each of the links, the manner in which the adjustments are eiiected will be described in connection with but one of the links. The vertical adjustment is effected by screwing up or unscrewing the stud 65 in the boss 62, and the horizontal adjustment is efiected by loosening the wing nut 60 and sliding the link 56 (which carries the member 55 with it) fore-and-aft any distance within the limit of. the slot 53, the link being maintained in any set position by tightening the nut 60,. To effect a lateral adjustment of V the member 55, the wing nut 63 is loosened and the boss 62 rotated in the bearing 6| and then clamped in set position by tightening the nut 63.

Furthermore, a slight rotation for aligning the member 55 with the welt of the shoe may be efi'ected, when desired, by rotating the stud 65 or by loosening the wing nut 60, and rotating the I entire connecting link 56, the former, however, being the usual method employed;

Thus, it will be seen that the additional pressure resisting means provided by the present inventionto cooperate with the welt of the shoe is capable of substantially universal adjustment, in

order that it may be adapted to cooperate with shoes of different sizes and, shapes. Furthermore, the links are independently detachable from the holder and are formed in sections so that substitution and replacement of the parts may be '60 efiected at a minimum cost. I

In the use of the shoe bottom attaching apparatus equipped with the additional pressure resisting device, the lasted shoe is placed in position on the pressure-applying member in the'manner.

already described. However, before the lock-up is made by the engagement of the yoke member 31 with one of the notches 40, the wing nuts 63 are loosened (or may already have been loosened to permit the positioning of the shoe in the ordinary manner) and the members 55 swung outwardly away from theshoe and'screwed up or unscrewed in the bosses 62 to shorten or lengthen the link, as desired, to secure proper engagement of the members with the welt of the shoe. When the links 56 have all been adshapes.

justed to the desired length, it necessary, the wing nuts 66 may be loosened and the links shifted in a iore-and-att direction properly to locate the members 55 along the welt. With these adjustments finally made, the lock-up between the -5 Y ke 31 and the reach arm 24 is effected, the pressure exerting member l3 inflated, and so' on,

all subsequent operations proceeding as usual.

01 course, it is to be understood that the dii-- ferent' steps in making the adjustments need 10 'only in connection with the full sole attaching apparatus, it may be applied to the half soling 15' unit equally as well.
