UNITED STATES PATENT OFFICE SHOE SOLE CEMENTING APPARATUS Herman Haselier, Garfield, N. .L, assignor to Barge Electric Shoe Cement Press, Inc., Brooklyn, N. Y., a corporation of New York Application March 2, 1934, Serial No. 713,706 11 Claims. (Cl. 12-33) can be used effectively on various types and styles of shoes without change or substitution of parts and which is yielding flexible and self conform- 10 ing to the shape of the bottom of the shoe .to be soled, irrespective of the curves, humps, depression 7 and uneven surfaces it may have.

A further feature is in the provision of means to facilitate setting of the cement, thereby to 15 increase the output of the apparatus fully fifty per cent above normal, while its operation ,is performed in a particularly rapid, sure and simple manner on one or more shoes at a time.

7 Another purpose is to produce a device embodying means to exert an-adjustable spring pressure on the sole, gradually applied and released, and capableofbeing locked when in operation, preventing displacement of the parts and possible injury to the operator.

25 These and other important objects, which will appear as the description continues, are accomplished by the novel and practical construction and combination of parts hereinafter described and illustrated in the accompanying drawings,

30 constituting a material component of this disclosure, and in which:

Figure 1 is a top plan view of a unitary embodimentwof the invention, showing its application.

Figure Sis a partial sectional view, similar to Figure 4, but showing a. modified form of sole cushion adapted to womens shoes having high heels.

50 Figure 9 is a rear elevatlonal view showing the apparatus as arranged for dual operation.

Figure 10 is an end elevational view of the apparatus as adapted for a plurality of shoes simultaneously undergoing soling operations.

55 -The simple form of the device shown in Figures 1 to 5, consists of a hollow base l5, preferably an aluminum casting and generally an elongated rectangle in profile, the frontend being bowed outwardly and the rear end concave, as seen in .Figure 1, the base having a chamber IS in its 5 upper side and recesses l'l-ll in its bottom, below which extend integral feet l8-l9 at the front and rear to rest upon a level supporting surface.

The upper edge of the chamber wall is generally 10- curved in conformity with the shape of the sole of -a shoe and isformed with an outstanding flange 20 and perpendicular front end wall 2|, both of which preferably have in the center of their width a continuous longitudinal groove 22. A fluid passage near one end is provided with a removable closure plug 23, for filling the chamber IS.

A flexible diaphragm or blanket 24, such as a sheet of rubber, and an overlying cover 25 of thin leather, is secured over the chamber I6 by metallic strips 26 formed with beads 21 to press the blanket and its cover into the groove 22, when the strips are drawn towards the flange 20 and face wall 2| by a plurality of clamp bolts 28, 25 thereby effectually sealing the fluid chamber I6 and its contents against evaporation and leakage, even when under a very considerable pressure.

In the recess H, in the underside of the base [5, (see Figures 4 and 5)-is an electric heating coil 30 having connections 3| leading to a thermostat in the recess H by which thetemperature is controlled in. the usual well known manner, and

provided with connections to any convenient source of current; the coilis held by an aluminum plate 33 fastened to the base l5 by screws 34.

The plate 33 is insulated from the electric heating coil 30 by a sheet 32 of material such as asbestos while a second sheet 35 of insulating material is arranged between the plate 33 and a cover plate, 36 which encloses the heating unit within the recesses I1 and I1 and is fastened to the base l5 by screws 31.

It is to be noted that heat from the coil is transmitted directly to the bottom of the chamber i6, 5 (see Figures 4 and 5) and communicated to the fluid therein, thus causing rapid heating in a substantially direct manner, a very little loss occurring.

A pair of opposed lugs 40 extend upwardly from the rear ends of the strips 26 carrying a bolt ll by which is hingeclly engaged the downreaching end of an inflexible arm extending forwardly at the center of the apparatus over the base.

The rear portion of the pivoted arm 42 is laterally enlarged to produce an enclosed housing 43 in which, pivoted on a screw bolt 44, is a hand lever 45, its forward, main portion being of considerable length for convenience of manipula-- 5' tion.

The rear of the lever 45 is shaped to produce a web 46, (see Figures 1 and 2,) integrally formed with a toothed sector 41, operatively engaging the teeth of a plunger rack 48, slidable perpendicularly in the housing 43, at the rear end of the arm 42.

The plunger 48 has on its rear side opposite the rack teeth, a plurality of ratchet teeth 50 engageable with the upper end of a detent bar. 5| freely is pivoted at 52 in the housing 43 and normally.

hanging pendant to engage the ratchet teeth by gravity, thus holding the plunger when it is raised.

On top of the plunger is a saddle 54 over which is disposed the central portion of a wire yoke- 55, its downwardly extending, divergent arms being formed into eyes 56 engaging the upper ends of a pair of strong helically coiled tension springs 51, connected at their lower ends to eye bolts .58

set in the forward portions of the strips 26..

From the foregoing it will be understood that when the pressure on the lever 45 is depressed, forcing the arm 42 downwardly towards the base, the plunger is raised and held in adjustment by the detent 5|.

In order to more thoroughly lock the plunger when raised, a bolt 60, secured by a chain6l to a ball 62, fixed in the head of the lever pivot 44, may be passed through any of the openings 63 in the sector web 46, thus positively preventing accidental displacementof the lever.

In the reduced web portion of the arm 42, adjacent its lower edge, are two series of openings 65, 66, respectively at the rear and front, and engageable selectively in the rear row is a pin 61,

5 shoe last X.

Similarly, another pin 1| passes through a like fork 12 to engage in any'of the openings 66, the

fork having a block 13 adjustably receiving a screw stud 14 engaging the hub 15 of a flexible 50 pad 16 adapted to seat on the forward part of a shoe in which the last X is contained.

In the modified form, shown in Figures 6 and 'I, the web of the arm 42 is formed with undulations 18 in its lower edge and parallel therewith 55. are opposed ridges 19 adapted to guide and support movable forks 88 suited to engage the web and ridges in a manner to permit ready adjustment, these forks being provided with pins 8| to engage selectively in the notches of the undula- 0 tions 18; in other respectsthe arrangement is the same .as previously described and obviously for the same purpose of adjustment in conformity to the size of the shoe being operated upon.

In Figure 9 the same general features appear,

65 the main difference being that the base is adapted to support a pair of the single independently operable devices heretofore described, the base having two upper chambers and lower recesses for the heating means, so that they can operate 70 individually or in pairs- Figure 10 shows the devices of Figure 9 arranged on a triangular frame I80 mounted for rotation upon a stand llil, thus economizing in space to a far greater extent than is possible with six sep- 75 arate devices. I

The electrical connections 8 i from each unit are brought to a common center and provided with a manually operable commutator I02 so that individual control is obtainable.

In operation, after the shoe has been placed upon the fluid supported diaphragm, with the sole to be cemented to it, the arm is swung down wardly to engage. the cros piece with the forward part of the shoe, the last X being previously positioned in the shoe.

The screw studs may be adjusted to different positions by reason of the selective openings in the web of the arm, whereupon the bight of the yoke is placed in the saddle and the hand lever actuated to raise the plunger, tensioning thesprings. r

- When the proper tension has been obtained, the detent automatically engaging one of the teeth of the ratchet retains the lever in its adjusted position; the lever may be further locked by the pin in an obvious manner.
