MACHINE FOR WIPING OUT BINDINGS.

Application filed March 5, 1918.

To all whom it may concern Be it known that I, JAMES E. MCINTIRE, a citizen of the United States, residing at ti eymouth, in the county of Norfolk and State of Massachusetts, have invented certain Improvements in Machines for \Viping Out Bindings, of which the following de-- scription, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for use in the manufacture of boots and shoes and is herein illustrated as embodied in a machine for producing a so-called French edge.

It is customary in the manufacture of certain styles of boots and shoes to bind the edges of parts of the uppers with a strip of fabric. To this end such a strip is stitched to the edge of the vamp, quarter or other piece of material which is to be bound, cement is applied to the strip, and then the free portion of the strip is folded about the edge of the material and pressed down so that the cement will hold it firmly in place.

There are two distinct steps in the formation of a French edge aft-er the binding has been stitched to the material. First the free portion of the binding should be wiped over that portion of itself which is attached to the material until the stitches smile, that is, until they can be plainly seen; and second, the portion of the binding which then extends beyond the edge of the material should be drawn tightly about said edge and maintained taut while it is laid over on the margin of the material. In my prior Patent, No. 1,278,490, granted Sept. 10, 1918, there is shown an edgefolding machine fitted for performing the second step referred to above, namely, the folding or drawing of the wiped out or straightened binding over the edge of the material; and the general object of the present invention is to provide an improved machine for performing the step of wiping out or straightening the binding preparatory to the folding operation.

According to one feature of the invention, a member movable in a path approximately parallel to the plane ofthework wipes the free portion of the binding over that portion of itself which is attached Specification of Letters Patent.

to the material. Conveniently the wiping member is in the form of a rotary disk having a corrugated operating face, and the work is fed to this rotary member by a cooperating feed roll and feed disk, the plane of the work being approximately parallel to the plane of the disk. \Vith this construction the free portion of the binding is turned through approximately 180 about its attached base and is pulled or wiped out very effectively.

In operating upon work of this kind, it is desirable to be able to control the rate of feed. For example, when the curved throat of a vamp is encountered, the rate of feed should be less. To this end, another feature of the invention comprises, in a machine of the class described, feed mechanism, a driving member, and a connection between the mechanism and member such that the operator may retard the feed by pulling back on the work. Conveniently this connection comprises a friction clutch the members of which are pressed together by a spring, and means for varying the tension of the spring.

These and other features of the invention, including certain details of construction and combinations of parts, will be described as embodied in an illustrative machine and will be pointed out in the appended claims.

Referring now to the accompanying drawrugs,-

Figs. 7 8 and 9 are perspectives showinga modified form of wiper.

Mounted in suitable bearings in the frame 7 of the machine is a driving shaft 9 having fast thereto a grooved pulley 11.. This pulley has a conical clutch face formed in one side thereof to receive .a correspondingly shaped clutch member on a driving pulley 1.3 which is loose on the shaft 9, a treadle rod and suitable connections bein provided to throw in this clutch when desired. The

"feed roll 17 is fast on the end of a horizontal clutch member 21 which is received in a' socket in a correspondingly shaped clutch member, said last-named member being integral with a grooved pulle 25 which is loose .on the shaft 19.. A coiled spring27, the tension of which may be varied by screwing a cap 29 to the right or left on the shaft 19, holds the members of the friction clutch in contact. 31 which passes around said I pulley and around a small pulley 33 which is fast to a short, rotatable, horizontal shaft, not shown. Fast to this same shaft is a larger pulley 35 which is driven bymeans of a belt 37 from a pulley 39 on the driving shaft 9. The feed disk 41, which cooperates with the cylindrical portion of the feed roll 17 is fast to a shaft 13 mounted in bearings in the frame of the machine, said shaft being provided with a collar 15 between which and the upper bearing of the shaft is located a coiled spring 17 which serves to hold the feed disk in contact with the work. The shaft 43 is splined, as indicated at 4:4, to the hub of a pulley 19 so that it may rise and fall in accordance with the thickness of the work without disturbing the driving connection between the pulley. and the shaft. A belt 53 passes around the pulley 4:9 and is received in the lower groove of a double grooved pulley 55 which is loose on a short upright shaft 57, this pulley being driven by a belt'67 which passes over

idler pulleys

69 and 71 and down around a pulley 73 fast to the shaft 19. With the construction thus far described, it will sire. The wiper 75 is fast to a stem 77 which is slidable in a sleeve 79 but is held from rota .tion with respectthereto by a pin 81 which passes through the stem and through dia metrically opposite slots 83 formed in the sleeve 79. A coiled spring 85, located between the upper end of the stem 77 and the lower end of the screw bolt 87, serves to hold the wiper 75 normally in the position shown but permits the wiper to rise to accommodate its position to the thickness of the work.

' The screw bolt 87 is threaded through the .top of the sleeve 79 and is held in adjusted position by aset nut 89. The sleeve 79 is rotatable in spaced bearings in a bracket 91, the stem 93 of-which is held in adjusted angular position by means of a thumb screw 95. Fast to the sleeve is a pulley 97 and beas tween the .pulley and a hollow threaded The pulley 25 is driven by a belt the wiper.

bushing 99 is a' thrust ball bearing 101.

The sleeve 79 is held, in the position shown 'by means of a collar 103 which is adjustably held in place on the sleeve 79 by a set screw 105. With this construction the lower limit of movement of the wiper 75 may be varied byvarying the position of the collar 103 on the sleeve 79, and the angular inclination of the sleeve and consequently of the axis of rotation of the wiper may be varied by loosening the thumb screw 95 and changing the angular position of the bracket 91. The pulley 97 is driven by a belt 107 which passes overvtwo idler pulleys 109, 111 and down around the pulley 11. The idler pulleys 109, 111 are vertically adjustable as indicated so'as to permit tightening of the .belt when desired.

It will be noted that the feed disk 41 extends beneath the wiping tool 75 and that when a piece of work is fed to the machine the feed disk is raised. In order to prevent it from coming into contact with the close to the upper surface of the feed disk 4:1 by a coiled spring 119, has an arm 121 adjustably fastened to the lower part thereof by aset screw 122, there being a yoke on the outer end of the arm which extends beneath a collar 123 formed on the stem 77 of The rod 117 is held from angular movement in its bearings by a screw 125 which extends into a slot (not shown) in the rod and is held from downward movement beyond a predetermined point by a collar 127 fast to the rod against which the lower end of the spring 119 bears. The collar 127 is adjustably held in place by a set screw and in connection with the spring 119 serves to hold the rod 117 in such a position that the disk 41 may rise a predetermined amount before the Wiper will be raised with it.

Fig. 5 shows the work in the condition in which it comes to the operator, said work consisting of a piece of material 100, such as leather, to which a strip of binding 200 is fastened by stitches 300.- Referring now to Fig. 4:, the operator pulls out one end of the free portion of the binding and presents the work to the machine, as shown in said figure. The feed disk 41 and feed roll to the upper side of said binding as it appearsin Fig. 5 and that consequently when the binding is wiped over into the position shown in Fig. 6, it retains this position so that it can then be readily fed to a folding In order to render the wiping member more efi'ective operative face may comprise a projecting annular p rtion 175 3 17 carry the work forward, and the tool 75 'bends the binding substantially 180 about having formed therein corrugations or pro-. jections 177. As the wiper rotates in the direction indicated in Fig. 4c and in a path the plane of which is approximately parallel to that of the work, these projections strike a rapid succession of blows and thereby impart permanence to the bend in the binding.

In Figs. 7, 8 and 9 is shown a modified form of wiper comprising a disk 179 having radial slots 180 to receive the spring arms 181 of a spider the hub of which is adapted to be received in a circular depression in the top of the disk. When the parts are as sembled, as shown in Fig. 9, a screw 183 holds the parts of the wiper together and fastens them to the lower end of the shaft 7 7. At this time the ends of members 185, which are carried by the spring arms 181, project beyond the lower face of the disk and serve the same purpose as the projections 177 of the disk 75,-the principal difference being that the members 185 may yield individually as they pass over the work,

Although the invention has been described as embodied in a particular 1nachine, it should be understood that the invention is not limited in the scope of its application to the particular machine which has been shown and described.
