j LASTrNG-MACEINE.

To all whom it may concern: j p

Be it known thatl I, PHILIP A. BOWEN, of Lynn, in the-county of Essex and State of Massachusetts, have inventedl lcertain new and useful Improvements` in Lasting-Machines, of which the following isa specification.

inverted position, is rested upon a Support` while the upper `materials are worked into lastedposition at one or both ends ofthe' shoe by Vend lasting devices or end lasting mechanisms. y r

The principal' object ofthe invention is to provide means whereby in lasting machineshaving features of adjustability'hereinafter referred to, the so-called wipers may be evenly, economicallyand v efficiently heated.l

For convenience in description the invention will'be hereinafter described in connection witha lasting machine patentedby Matthias Brock,in Patent-No.'1,`018,477, dated February 27th, 1912, and for thepurposes of this specification will be considered as any improvement upon that -machine although vits n j vmay be tipped laterally to adapt them to the more general application will be obvious.

One embodiment of the invention is shownv in the accompanying drawings and therein- Figure 1 is a plan view of a portion of a lasting machine embodying the invention, Fig.-,2 is a corresponding sideelevation, Fig. 3 is a section on the line 3 3 of Fig. 1,' A f Fig. y4 is adetailed j view ofthedwipers and heating means, and f Fig. 5 is a detailed view of theheating means apart fromk the lasting machine.

For the purpose of illustrating and' de- Y accordingly only parts believed to be essential will be hereinafter described. Reference may be had to the above `mentioned This invention relatesto improvements in screw 47 provided with a hand wheel.

chine, and therein the toe-lasting mechanism-is carried bya bed plate 21, which may be vertically adjustable.. A-Screw 33 provided kwith a hand wheel is secured to the frame 37 kof the toe-lasting mechanism and has screw-threaded engagement with a stationary block 39 on the bed plate for moving the 'toe-lasting mechanism forwardly and backwardly to position it for lasts of different lengths, the toe rest being moved lengthwise of the'shoe with the toe-lasting mechanism by suitable means. A carriage 41 is herein shown as pivotally connected at 43, ywith the frame 37 and arranged for lateral movement about its center by means of rlthe he toe-lastingy devices are supported on a head which is pivoted at 51 to the carriage 41 andJmay be adjusted vertically about said pivot by the screw 53,'having the hand wheel 55. The lastingdevices are carried by a sleeve 57, to which issecured a segment 59 engaged' by a screw 61having a handle 63. By this latterv means the toe-lasting devices lateral inclination of the bottom of the shoe. The Qtoe-lasting devices comprise wiper plates 67 removably vattached to the carriers 69 and arranged for movement rearwardly and inwardly'over the bottom of the toe portion of the last. This movement is effected by connections including the links 71 and-equalizing lever 73 with an endwise movable rod 77 to which is connected the hand lever 7 9.

It is particularly desirable in lasting man chines that the wipers be heated to assist in the voperation of drawing the upper leather over. the toe or heel ofthe shoe, as the case may be, before it is tacked, wired or otherwise secured in place, preparatory to the final stitching.

The advantages of heated wipers are generally recognized and the diiculties with prior machines have generally been in securing an even and uniform degree of heat in the wipers. It will be readily comprehended that if the wipers are overheated the leather of the shoe will be burned or otherwise disfigured and the shoe injured beyond repair or the leather permanently weakened. Furthermore in the most efficient lasting machines such as the type of machine herein illustrated7 the head of the machine is adjustable in all directions, that is to say, it may be moved toward or from the last support, the wipers may be tilted in the plane of the last or rotated from that plane in order to secure proper adjustment with varying shapes and sizes of lasts. Furthermore it is desirable that the wipers themselves be readily interchangeable so that the machine may be used upon different styles of shoes, a differently formed wiper being required for differently shaped lasts.

The present invention provides means whereby the desired results may be accomplished, such means being herein as follows: A pipe 100 is connected to a. suitable source of gas supply by a flexible tube 1017 the said pipe 100 being mounted upon the movable head of the lasting machine and extending conveniently through a centrally bored hole 102 in the rod 77. A cock, in the form of a screw 103 is provided to adjust the flow of gas from the source to a pair of burners 104 and 105 formed by a pair of branching tubes 106 and 107. These tubes are so positioned that the flame at the burners 104: and 105 is directed toward the underside of the wipers 67 when the wipers are in retracted position. The gas supply is preferably so adjusted that a blue fiame is produced at the burners in order that the wipers may not be smutted and thereby soil the leather of the shoe, and the flame is preferably directed outwardly away from the slice in order that the leather may not be burned or scorched.

It will be apparent that proper adjustment of the flames may be made by the cock 103 so that the wipers will be maintained at proper temperature, and the branching tubes 106 and 107 leading from the common supply pipe 100, wherein the cock 103 is located, insure equal heating of both wipers. During the operation of the machine the wipers are normally maintained in retracted position for the greater portion of the time during which the machine is in use, and the arrangement shown will thus insure the maintenance of a substantially uniform degree of heat in the wipers.

In operation, it is customary to insert a last in the machine, to then adjust the head forward or back as the needs of the moment may'require, and to adjust the head in any other direction permitted by the several adjusting means heretofore described. The wipers are then brought forward from the position shown in Fig. 2 by movement of the handle 79. It will be apparent that during the adjustment of the head, the burners are carried with the head and maintained in their predetermined relation with the wipers so that the movement of the head has no effect upon the heating means to destroy the proper relation between the burner and the wiper.

It is of course obvious that the improvement herein shown may be applied to the heel wipers as well as to the toe wipers with equally advantageous results. It should be understood that the invention may be variously modified and embodied within the scope of the subjoined claims.

l claim as my invention:

1. The combination with a lasting machine having an adjustable head, of a pair of wipers mounted thereon; means mounted upon said head providing burners for heating said wipers; and means connecting said burners with a source of fuel supply.

2. The combination with a lasting machine having an adjustable head and a fixed base; of means to move said head in a plurality of directions relatively to said base; wipers carried by said head and movable therewith; means providing burners also carried by and movable with said head to maintain said burners in predetermined relation with said wipers when in retracted position to uniformly heat the same; and a liexible connection from said burners to a source of fuel supply therefor.

In testimony vwhereof I have aflixed my signature, in presence of two witnesses.

PHLIP A. BOWEN.
