This invention relates to fluid coating machines of the kind used in the manufacture of footwear, and more particularly to a cementing machine for applying cement to welt lasted uppers prior 5 to afiixing an outsole thereto.

A general object of the invention is to provide a bottom cementing machine which is adapted to handle welted uppers so as to apply a coating of cement to the welt and inseam portions m thereof.

More specifically, objects of the invention are to provide a cement applicator having a work support which is adapted to hold the extended edge of 'a welt against the applicator surface to insure proper fluid applying contact between it and the welt.

A further object of the invention is to provide a welt supporting attachment which may be used with existent forms of bottom cementing machines.

, Other objects of the invention will in part be obvious and will in part appear hereinafter.

The invention accordingly comprises the features of construction, combination of elements,

and arrangement of parts, which will be exemplified in the construction hereinafter set forth and the scope of the invention will be indicated in the claims.

For a fuller understanding of the nature and objects of the invention reference should be had to the following detailed description taken in connection with the accompanying drawing, in which:

Fig- 1 is a fragmentary top plan view of a bottom cementing machine equipped with a welt support constructed in accordance with the principles of the present invention; and

Fig. 2 is a vertical sectional view taken alon line 2-2 of Fig. l.

It is now becoming the practice to the outsoles of welt type shoes to welted uppers by means of cement instead of by stitching. In following this recently developed practice, the upper is lasted in the usual or any suitable manner, for example by the familiar steps used in constructing a Goodyear welted shoe, and the inseam thereof is closely trimmed. The inseam and welt are roughed to provide a suitable sur-' face for cementing. The cement is applied to such roughed inseam and to the bottom of the welt and preferably also marginally around an outsole. These parts are then stuck together in a sole press. The cement may be applied by any suitable type of bottom cementing machine now in use for handling non-welted uppers of McKay or related types, provided it has an applicator capable of covering the welt and inseam area.

When cementing welts, care must be taken to see that the extended welt edge, which is un- 5 supported by the last, is held in cement receiving relationship against the face of the applicator. The present invention provides a device especially suited for doing this which is capable of being mounted on any suitable type of bottom cementing machine, being herein illustratively shown mounted on a cementer of the kind shown in the copending application of William C. Card, Ser. No. 105,180, filed January 4, 1934.

Referring more particularly to the drawing, 15 there is shown the upper portion of a cement applying machine having an applicator it with a rim ll of rubber or like compressible material which is adapted to have cement deposited on its periphery by means of a cement transfer 20 wheel it which in turn has cement deposited thereon by any suitable means, for example that shown in the above mentioned Card application.

A drive shaft I3, which is adapted to be driven in any suitable manner, is provided for the ap- 5 plicator l0, and the shaft and applicator in are preferably mounted in inclined position, as shown in Fig. 2, so that the lower work engaging periphery of the latter is positioned so as to enable the operator to see the work at the point of 30 cement application. A hinged cover it is provided, which has a forwardly extending portion l5 closely overlying and covering the upper end of the applicator Ill. a

A threaded pintle I6 is provided in such cap 35 portion and is adapted to provide a hearing about which the applicator may be rotated, and also to hold' such applicator in position with respect to its drive shaft, there being a slot and, tenon connection ll between these parts which 40 permits removal of the applicator when desired. These above disclosed parts are constructed in accordance with the showing in the mentioned Card application.

In order to handle welted work in an improved 45 manner, a block I8 is screwed to the cover extension it: by means of screws is which are extended through slots 20 to enable the block to be adjustably positioned on the cover. Such block is recessed as at 21 to accommodate the 50 pintle l6 and it has a. pair of hollow bores 22 extending longitudinally thereof. A removable welt support holder 23 is provided with pins 24 which extend slidably into bores 22 to permit guided movement of such holder with respect 55 means of a screw 2? passing through a slot 2% which permits vertical adjustment or" the support in respect of its holder. The downwardly extending portion of this support terminates in a tapered finger 29 which is adapted to enter the welt crease of a lastedwelted upperso that its'facc 3t serves to hold the extended edge of the welt in cement receiving contact with the applying periphery of the applicator, spring 25 acting to give the welt a slight spring tension against the applicator 'face and also yielding to accommodate diiierent thicknesses of work. A guide shoul der 3i is provided on the welt support in position to engage the edge of the welt and prevent it from moving upwardly, beyond the cement bearing surface of the applicator.

In operation the welt support and holder are pulled outwardly ,by hand and the welt and inseam portions of the lasted upper are placed against the applicator periphery with the,fin ger of'the welt support located in the welt crease, after which the support is released in order to enable the spring 25 to hold the welt against the applicator. The shoe is held in this position by the operator during ensuing feeding and applying movements, until a band of cement is deposited on the welt and inseam portions of the shoe from the heel breast line at one side entirely around its forepart and back to the heel breast line at the other side.

Since certain changes may be made in the above construction and difierent embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is:

l. A bottom cementer for welted shoe uppers comprising a. rotatable yieldable applicator roll havinga portion of its periphery exposed for contacting work presented thereto, means for delivering cement to said applicator, and a welt support engageable in the welt crease of a welted upper comprising a finger having its welt engaging face substantially parallel with and located opposite to said workcontacting portion, said support being slidably and yieldably mounted in operating position for straight-line movement toward and away from said applicator.

2. A bottom cementer for welted shoe uppers comprising a casing, a rotatable applicator having a peripheral portion extending from said casing for contacting work presented thereto, means for delivering cement to the periphery of said applicator, a welt support engageable in the welt crease of a welted upper and slidably mounted on said casing, and spring means giving said support a bias toward said applicator.

3. A bottom cementer for welted shoe uppers comprising a casing, a rotatable applicator having a peripheral portion extending from said casing for contacting work presented thereto, means for delivering cement to the periphery of said applicator, guide means mounted on said casing, a welt support engageable in the welt crease of a welted upper and slidably mounted on said guide means, and spring means giving said support a bias toward said applicator.

a. A bottom cementer for welted shoe uppers comprising a housing, a rotatable applicator mounted thereon, means for depositing cement on the periphery of said applicator, a block mounted on said housing, a welt support holder, guide pins slidably holding said holder on said block, a spring normally urging said holder toward said block, and a welt support extending from said holder in position to enter the welt crease of a welted upper having its welt opposed to the cement bearing periphery of said applicator so as to hold such welt thereagainst.

5. A bottom cementer for welted shoe uppers comprising a housing, a rotatable applicator mounted thereon, means for depositing cement on the periphery of said applicator, a block mounted on said housing, a welt support holder, guide pin slidably holding said holder on said block, a spring normally urging said holder toward said block, a welt support extending from said holder in position to enter the welt crease of a welted upper having its welt opposed to the cement bearing periphery of said applicator so as to hold such welt thereagain'st, and a guide shoulder on said welt support for engaging the edge of such welt.
