GEORGE E. ROLLINS, OF BROCKTON, MASSACHUSETTS.

MACHINE FOR IPRIEPARING INEJOLES.

To all 107mm 1'6 may concern:

Be it known that I, Gnoncn 1G. Romans, a citizen of the United States, residing at Brockton, in the county of Plymouth and State of h Ifassachusetts, have invented new and useful Improvements in Machines for Preparing Insoles, of which the following is a specification.

This invention relates to machines for preparing insoles, the object being to provide a machine for more efficiently tucking the reinforcing material of an insole into the angles where the lip of the insole joins the marginal feather.

The machine is designed to operate upon an insole to which the reinforcing material has been stuck preferably by cement, but which has not the reinforcing material tucked into the angles as closely as is necessary. One instrmnentality of the present machine engages the free edge of the lip and bends the same inwardly, thus drawing the reinforcing material away from the feather. This instrmnentality holds the lip while a second instrumentality tucks the re inforcing material into the angle at the junction of the lip and feather, said tucking member having imparted thereto, in addition to its inward and outward movement, a lateral movement which is utilized for feeding the work and causing a portion of said tucking member, which engages said work, to be moved in an elliptic path. Furthermore said tucking member is adapted to press said reinforcing material upon the marginal feather and to bend said feather away from said lip in order to shape the insole so that there may be more space for the needle of a sewing machine when said insole is subsequently attached by sewing to the upper of a boot or shoe.

In addition to the above instrmnentalitics a third instrumentality is provided to engage the inner side of the lip and to tuck the reinforcing material thereof into the angle at that side and to support said lip during the actions of said bending and tucking instrumentalities.

The invention consists in the combination and arrangement of parts whereby the above object and certain other objects hereinafter appearing may be attained, all of which are set forth in the following specification and particularly pointed out in the claims.

Specification of Letters Patent.

Application filed March 8, 1913.

Serial No. 752,816.

Referring to the drawings: Figure 1 is a vertical section, partly in elevation, in a plane from front to rear of a machine embodying my invention, a portion of an insole being illustrated in connection therewith and the several working parts of said machine being illustrated in operative positions. Fig. 2 is a plan view of a portion of the gearing of said machine. Fig. 3 is a detail plan view of the outer tucking and feeding instrumentalities together with other elements of the mechanism closely associated therewith. Fig. 4: is a plan view of an adjustable holder for the lip bending instrumentz'ility. Fig. 5 is a vertical section partly in elevation through the adjustable structure which supports and drives the outer tucking instrumentality, looking from the rear of said machine. Figs. 6, 7 and 8 are enlarged sections of an insole illustrating the condition of the same before, during and after it has been treated by the present machine. F 9 is a vertical section through the work gaging instrumentalities and the means for driving the same, said section being taken on a plane similar to that to which Fig. 1 is taken on a somewhat enlarged scale.

Trike numerals refer to like parts throughout the several views of the drawings.

The frame of the machine is indicated at '10, and it is provided with suitable bearings ll. for :1 Prime Power shaft '12. The shaft is provided with the usual pulleys 13 and 13, one of which is tight and the other loose. A vertically movable work support is indi rated at 14.. This support is circular and has a transverse top surface 15 and a beveled marginal surface 16, which surfaces are provided for engaging respectively the flat body portion X and the marginal feather X of an insole. The work support is intended to rotate about a vertical axis, and for this purpose it is provided with a cylindric hub or stem LT, and this stem is mounted in a sleeve 18. The work support is atlixed to the sleeve, and the sleeve is mounted in suitable bearings 15) in the frame and is adapted to rotate to move ver tic-ally in its bearings. A worm gear 90 splined upon the sleeve and is disposed between the bearings 19. This gear is driven by a worm 21 on the shaft 12. The work support is normally elevated by a compression spring 22 disposed in the sleeve, the

upper end of the spring bearing against the hub 17, and the lower end bearing against an adjustable abutment 23. This abutment is adjusted by means of a screw 24 engaging the frame 10. A spool 25 mounted upon the sleeve is engaged by a forked lever 26, the latter being mounted upon a fulcrum stud 2? and being provided with a treadle rod 28 whereby the work support may be depressed against the force of its spring when the treadle rod is depressed. The spool is adjustable relatively to the sleeve and rests upon a collar 29 which is adj ustably secured to the sleeve by a set screw 30. This collar will be adjusted according to the thickness of the soles upon which the machine is to operate, to the end that the force of the spring 22 may be used to force the insole against the instrumentalities which act upon the material a with which the insole is reinforced.

The tucking tool which operates upon the inner side of the lip X is indicated at 31. V

The end of this tool is pressed by a spring against the reinforcing material on the flat part of the sole, this pressure being constant, while at the same time the tool is rotated about its axis for the purpose of assisting in feeding the work. The tool is preferably made in two parts, the part indicated at 31 being the work-engaging part, and the shank indicated at 32 constituting the main body of the tool. The joint indicated at 33, whereby the two parts are joined, comprises a male threaded portion on the part 32 and a threaded socket in the part 31, the screw thread being a left-hand thread in this instance because it is desired to have the threaded parts automatically tightened when rotation is in the direction of the arrow. The shank 32 is mounted in a sleeve 34, and its upper end has a sliding fit in a bushing 35 which is screw-threaded in the sleeve. The function of this bushing is to compress a helical spring 36 whose lower end engages a collar 37 affixed to the shank 32. The sleeve 34 is mounted and rotatable in a stationary bearing 38 which is an integral or attached part of the frame 10. The bearing 38 is recessed for the reception of a helical gear 39, which gear is connected to the sleeve 34 by a spline 40. Hotation is imparted to the gear 39 from a gear 41 by an intermediate gear 42. The gear 41 is aflixed to the upright shaft 43 which has at its lower end a spiral gear 7 2 intermeshing with a spiral driving gear 73 on the shaft 12. Rotation of the sleeve34 is transmitted to the shank 32 by a pin 44 connecting the two, the sleeve 34 being slotted at 34 to permit slight yielding of the tool 31. The sleeve 34 is held against longitudinal movement by collars 45 which have set screws 46.

The shape of the tool 31 is such as to tuck the reinforcing material snugly into the angle of the sole and the inner side of the lip X and also to enable the lip lean inwardly, as shown by Figs. 7 and S. The lip is bent inwardly, as shown, by roll 47 which is rotatable, the members 31 and 47 cooperating in such manner as to pinch the lip and cause it to. assume an inclined position; The work-engaging surface of the roll 47 is frusto-conical and engages the lip at the extremity of the latter but not otherwise. This roll is loosely mounted upon a spindle 48 which is affixed in a holder 49. A pinion 50 is compounded with the roll and is driven by a gear 51 through an intermediate gear 52. The gear 51 is affixed to a shaft 53 which is mounted in a swinging carrier 58. This shaft extends through an elongated hole 55 in the holder 49, this hole permitting adjustment of the roll 47 toward and from the tool 31. The rear end of the holder 49 is formed with a recess 56 which is occupied by a stud 57, the stud being affixed to the aforesaid carrier 58. The stud 57 has a shoulder 59 which the bottom surface of the holder 49 and clamping nut 60 which engages the top surface,- the aforesaid recess permitting adjustment of the holder, and the shoulder 59 and nut 60 serving to clamp the holder rigidly with relation to the swinging carrier 58.

The carrier 58 supports a forming-in tool 61 which has a wiping action upon the feather X and which tucks the reinforcing fabric into the angle of the lip and the feather. The forming-in tool is mounted upon an eccentric 62 carried by the shaft 53. The rear end of the tool is forked, as indicated at 63, and straddles the stud 57, the stud serving as the fulcrum of the tool and the tool receiving a forward and back motion combined with a lateral motion whereby the work-engaging portion is caused to describe an elliptic path. This tool engages the bottom of the roll 47 and holds the roll on its spindle 48, the two work-engaging instrumentalities being contiguous, and the spindle 48 serving to keep the tip of the tool 61 pressed downwardly against the feather of the insole. The under surface of the tool 61 is substantially par allel to the adjacent portion of the surface 16 of the work'table, these two confronting surfaces being at an angle to the main portion of the work table and therefore adapted to bend the feather to the position shown by Fig. 8. The feather is thus bent away from the lip X and the lip is bent away from the feather, the separation of the lip and feather causing the reinforcing material to. pulaway from the bodies of the lip and the feather as shownby 7. While the reinforcing material is thus freed from the feather for the greater portion of the width of said feather, the forming-in tool 61 is thrust forward, thus entirely freeing and carrying the reinforcing material into the angle and drawing the edge of the reinforcing material inwardly within the margin of the feather, as shown by Fig. 8 it being understood that although the outer margin of the reinforcing n'iaterial may be engaged by the under surface of the tool (3] just prior to the inward or fcrward movement of said tool, the pressure at such a time upon said material would not be sutlicient to prevent said reinforcing material from being drawn iiiwardly relatively to said feather and at which time said reinforcing material will be ei'itircly freed or detached from the surface of said feather, but still in contact with a portion thereof. The lateral movement of the tool 61 causes the forward edge to score the reinforcing material for a short distance along the angle, which the bottom surface of the tool continues to press against the feather. By thus freeing the reinforcing material from the feather prior to tucking it into the angle, the forming-in tool draws the reinforcing material inwardly from the edge of the sole instead of drawing the reinforcing material from the lip toward the feather. The forming-in of the reinforcing material does not stretch that portion which covers the lip, and consequently when the sole is removed from the machine there is no tendency on the part of the reinforcing material to pull the lip toward the feather nor to pull the feather toward the lip, and these parts are adapted to remain bent, as shown by Fig. 8.

As shown by Figs. 3 and 5, the carrier 58 is mounted to swing upon a fulcrum stud 54lwhcreby it is connected to a bracket 1O or other stationary part of the frame 10, the axis of the stud being parallel to the axis of the shaft The purpose of the swinging movement is to permit retraction of the tools .157 and 61 when inserting and removing the work and also for the purpose of keeping the roll 47 against the lip when the machine is in operation. A spring for the aforesaid purpose is indicated at (wt in Fig. One end of this spring is inserted in a suitable socket in the airrier, and the other end is inserted in an adjustabli screw (35. This screw is threaded in the frame 10 and is adapted to cause the spring to act with more or less force. The carriru: extends to the opposite side of the shaft 5; and fulcrum stud 54- and is formed with a socket for the reception of one end of a pin (36 which transmits motion from a bell-crank (37 mounted upon the stud 27. A. treadle rod (38 is z ttached to the bell-crank and when depressed it swings the tools l and (51 away from the work and about the axis of the stud 5a.

The lower end of the shaft 53 provided with a spiral gear 6i) which is driven by a spiral gear on the main shaft 12 through an intermediate gear 71 mounted upon the fulcrum stud 54-.
