This invention'relates to the manufacture of boxings for shoes and particularly to MACHINE r03 MAKING snon-iaoxines.

To all whom it may concern:

Be it known that I, ROBERT citizenof the United States of America, and resident ofMarlboro, in the county of Middlesex and State of Massachusetts, have in-' vented certain new and useful Improvements in Machines for Making Shoe-Boxings, of which the following is a specification.-

means .forproducing. a boxing, stifl'ening whicl can be substituted for the-leather boxings .now so commonly employed without materially detracting from the durability or efficiency of the product in which .the sub stituted boxing is employed.

object-of thisinvention is to provide novel means for impregnating, saturating or substantially saturating .a fabric, preferably a textile fabric, with a liquid material which will, upon drying or cooling, solidify and re-" inforce or stiffen the fabric .tov such an -extent= as to be useful as a boxing for shoes, means being also provided whereby the said fabric may be. treated while the shoe isin,

process of manufacture and after the fabric has been secured to the vamp of the shoe, and also to the tip, or when the-vamp, tip

and fabric are sewed together, thus making 3 it possible for the operator to apply the stiffening agent to the fabric and shape the boxing together with the vamp and tip on a last while the fabric is pliable and before the coating or stifiening agent has hardened, it having been found in practice that this insures proper contouring of the tip and boxing with relation to the last and by reason of the fact that the fabric is secured to the vamp, creeping or independent movement of the boxing is prevente I A stillffurther object of this invention is to provide novel means by which the coating or stiffening agent is applied to the fabric and also'to provide means for agitating the material at each operation of the machine to prevent sediment collecting and the invention further contemplates the production of a device of the-character noted which will possess advantages in points 'of simplicity, efficiency and durability, proving at the same time inexpensive 'to produce.

With the foregoing and other objects in Specification of Letters Patent. r

The frame 8 is also provided witli guide pulleys 11 over which a chain 12 or other flexible connection may operate, the

said flexible member being connected-to the lever 9. .It is obviousthat any appropriate means maybe substituted for the operating means as the only requirement is that provi sion should be made for raising and lowering parts of the mechanism for the purpose of bringing the movable parts into operative relation to a stationary or other part which will coact with the movable member or part, substantially as will presently appear.

. I. prefer to employ a jacketed receptacle 13-with pipes 14 and 15 communicating with the interior of the jacket so that a heating agent may be circulated for/the purpose of melting the contents of the receptacle. 'As

at present carried on, I utilize an element or agent for stiffening the fabric which has a -As a'means'for: agitating the relatively high melting point and, therefore, it is necessary to have a capacity to heat the said agent to liquefy it and this, of course,

would depend upon the agent to be employed, and that may be changed to suit particular requirements.

A yoke 16 reciprocates 1n arms or other stationary means 17 which support the j acketed receptacle, or otherwise, and brackets 18 support a crosshead 19, and saldcross .head carries a mandrel 20 against which a presser head operates as will presently ap- :pear.

The head 21 of the yoke carries a depending arm 22 which arm extends within the jacketed receptacle and the said arm has a right angular extension which carries a presser head 23, the said presser headcomprising a plate and a cushion 24, which cushion is preferably of an absorbent nature which will take up a quantity of the liquid contained within the receptacle. As

a further means for insuring a supply of the fluid, a shield 25 is applied to the presser head and the said shield consists of a band of metal embracing the edge of the presser head and in normal position, its edge extends slightly above the upper surface of the cushion so that a film or layer of liquid will be held on the cushion when the presser head is elevated. The shield is yieldingly held in place by springs 26 extending across the bottom of the plate and projecting under the said shield, so that when the presser. head moves upwardly and the edge of the shield engages the fabric, the springs yield sufiiciently to permit the shield to move with relation to the presser head as is shown in Fig. 6 of the drawing.

the receptacle, a stirrer shaft comprising a worm or the like 27 is j ournaled in a bear ing 28 in the bottom of the receptacle and a pin 29 carried by the depending arm 22 engages the worm. and as the arm isreeip- 'rocated, it causes the worm to rotate, thus carrying the stirrer blades 30, causing them,

as stated, to agitate the contents of, the, receptacle. he worm may have its upperend journaledin the cross arm 19. a I

The construction and operation will, it, is thought, be understood from the fore oing description and a consideration of the ings, it being apparent that a fabric may be coated and impregnate'db being applied to the mandrel 20 while t e vamp'31, a

fragment of which is shown, the tip 32, and-- the tip lining 33 are held in substantially the position shown in Fig. 1-, after which the treadle can be operated to raise the yoke and with it the arm 22 carryin the presser head, so that material earned y the saturated cushion and confined thereon bythe shield is brought into contact ,With the fabric, thus pressing the fabric between the presser head and mandrel, and forcing or contents of awv plate and cushion and havm squeezing the liquid into said fabric. Thereafter, the tip and tip lining may be brought into contact with the opposite surfaces of the coated fabric and the three layers of material will be caused to adhere, since as stated, the coating will begin to harden as soon as the temperature is reduced and immediately thereafter, the shoe may be lasted to give the boxing the required configuration and when the coating hashardened, a satisfactoryproduct will result. I

By means of the apparatus, therefore, and

the mode of operation, a shoe having a boxing may be made expeditiously and the boxing thereof will'remain stifi under ordinary conditions of wear. 1 v I claim 1. Means for making shoe boxings .com-
