MACHINE FOR ROLLING SOLES.

Application led October 24, 1927.

This invention relates to a machine for rolling and pressing soles applied to foot wear. Shoe soles are now cemented onto the shoe upper in many instances instead of nailing or pegging, and when the sole is so applied it is desirable that the sole be firmly pressed and rolled out so that the cement will be of equal thickness therebeneath, forming a good strong bond between the shoe sole and the shoe upper.

An object of the invention is to provide a machine for rolling and pressing shoe soles, which is easily and quickly operated, and which will exert the desired amount of pressure on the shoe sole to accomplish the purposes above mentioned.

Another object of the invention is to provide a machine which is so constructed that the work can be easily and quickly applied to the machine or removed therefrom.

A further object of the invention is to provide .a machine which is of cheap, simple and durable construction, and which will effectively press and roll soles applied to foot wear.

Another object of the invention is to provide a machine having a. roller adapted to be passed over the bottom of a slice sole to press it, and which is so constructed that the roller will eXert an equal pressure at different points over the shoe sole regardless of the curvature of the sole.

With the foregoing and other objects in view which will be made manifest in the following detailed description and specifically pointed out in the appended claims, reference is had to the accompanying drawings for an illustrative embodiment of the invention, wherein:

Figure 1 is a view in side elevation of the improved machine, parts being broken away and shown in section.

Fig. 2 is atop plan view of the machine, parts being broken away and shown in section.

Fig. 3 is a vertical section taken substantially upon the line 3-3 upon Figure 1.

Referring to the accompanying drawings wherein similar reference characters designate similar parts throughout, the improved machine consists of frame having a hase Serial No. 228,238.

which may he made up of two angle irons 10 and 11 connected by cross bars 12, 13 and 14. Adjacent one end of the base there are secured two stationary uprights 15 and 16. On the opposite end of the base a pair of uprights 17 and 18 extend upwardly and have secured thereto channels 19 and 20. If desired, the uprights 17 and 18 may be formed by merely bending' the ends of these channels downwardly. The two channels 19 and 2O have their flanges or open sides extending toward each other and form tracks on the frame. Their rear ends are connected by a cross bar 21 which has a latch har 22 secured thereto adapted to be engaged by spring latches 23. The lower ends of the uprights 17 and 18 are pivoted as indicated at 24 so that the forward uprights and the channels may be swung forwardly or they may be locked in the position shown in Figure 1 by the spring latches 23. A carriage is provided which is in the form of a U- shaped yoke having parallel arms 25 and 26 which are somewhat crooked as shown in Figure 1, and which have their upper ends connected by a cross bar 27. The arms 25 and 26 carry pintles 28 intermediate their ends, on which rollers 29 are rotatably mounted. These rollers lit and roll within the grooves provided by the opposed channels 19 and 20. A roller yoke having parallel arms 30 and 31 connected by a cross bar 32, is carried by the carriage and the forward ends of the parallel arms 30 and 31 are pivotally connected to the arms 25 and 26 as indicated at 33. On the cross bar 32 there is pivoted an upstanding holt 34 which eX- tends upwardly through. a sleeve 35 and through the cross bar 27 having a wing nut 38 threaded onto its upper end. A coil spring 39 is disposed about the bolt and is compressed between the cross bar 32 and the sleeve 35. A cross bar 4() connects the arms 25 and 26, and has secured thereto a rack 41 which rests within a notch formed in the center of a cross bar 42 connecting the two uprights 17 and 18. A short distance above the cross bar 42 there is a shaft 43 adapted to be rotated by means of a crank 44 in bearings provided on the` upd rights. This shaft has a gear ft keyed thereto which meshes with the rack 41. From the above described construction it The two cross bars 13 and 14 serve to support a last 46, which last constitutes a workholder and is preferably replaceable or at least has a replaceable head so that it may accommodate work of various sizes. A brace member 47 is pivoted to one of the angle irons forming the base, and when the trame is in its forwardly extending position, this brace is adapted to enter a notch 48 in the upright 17 so as to support the frame in its elevated or forwardly swung position. A roller R is rotatably mounted on-an axle 49 which connects the two arms 30 and 81 of the roller yoke.

rbe moved back and forth by means of the gear 45, causing the carriage to move back and torth with its rollers 29 rolling within the channels 19 and 20. As clearly shown upon Figure 1, the channels 19 and 21 are curved so that they are substantially parallel to the top surface et the last 46. The bolt 34 limits the downward movement o1'2 the roller yoke against the action et the coil spring 39, and by virtue oiE the tact that the track provided by the channels is curved, the roller B will be caused to move through a curved path parallel to the top of the last. rlhe spring 39 urges the roller yoke and roller toward the last and causes the roller to exert a continual pressure on the shoe sole, which pressure will be substantially even all over the sole by virtue of the lact that the carriage moves on a track parallel to the last. By reciprocating the rack 41 back and forth several times, the roller R will be caused to press out the shoe sole and to squeeze out surplus cement. It also presses the shoe sole against the shoe upper so that a firm, strong, adhesive bond will be established therebetween by the cement. As soon as the roller R has been moved back and torth over the shoe sole, the desired number ot' times so that ythe sole will be iirnily fastened by the cement, the latches 23 can be caused to disengage the latching bar 22 and the traine can beswung torwardly about its pivot 24. It can be held in this position by causing t-he brace 47 to enter the notch 48 while new work is being substituted for that already on the machine. The pressure exerted by the roller R against vthe shoe sole can be varied by tightening or loosening the wing nut 38 so as to raise or lower the position of the roller on the *carriage.

will be appreciated that a novel machimx is provided which will elliciently, etlectively and quickly cause a shoe sole to be iirmly adhered to a shoe upper.

Various changes in the details ot construction may be made without departing from the spirit or scope of' the invention as detined by the appended claims.
