FREDERICK M. FURBER, .OF REVERE, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MACHINERY CORPORATION, OF PATERSON, NEW JERSEY, A CORPORATION OF NEV JERSEY.
MACHINE FOR USE IN REPAIRING ENAMELED LEATHER.
Application filed April 19, 1919.
To all wiwm it may concern:
Be it known that I, FREDERICK M. FURBER, a citizen of the United States, residing at Revere, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Machines for Use in Repairing Enameled Leather, of Which the following description, 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 designed to prepare the injured tips of enameled shoes for the repairing of the enamel.
In the manufacture of shoes having patent or enameled leather tips, the enamel is often cracked during the pulling over and lasting operations. To repair the cracked enamel, it is customary to remove enamel from about the cracks and apply size to the exposed surface of the leather preparatory to reenameling these surfaces by means of a tip repairing machine.
Hitherto it has been customary to employ a scouring wheel or a canvas covered wheel to scour off roughly or to burn off roughly the enamel about a crack, this operation leaving an exposed surface bounded by a more or less abrupt shoulder. The shoulder was next beveled by a manual scouring operation, very fine sandpaper being used. Next a coating of size was manually applied, and finally the size was brushed in to provide a smooth finished surface to receive the repair enamel. Thegeneral object of the present invention is to provide in one machine mechanism by which all of this preparatory work may be done more rapidly,
with a saving of sizing material, and with an improvement in the result.
To this end the illustrative machine comprises a roughing-out tool in the form of a rotary canvas covered or abrasive covered wheel for removing the enamel from about a crack, a smoothing tool in the form of an oscillating wheel having a cover of fine abrasive material for beveling the shoulder which results from the action of the roughing-out tool, a size-applying brush to which size may be fed in measured quantity, and a rotary brush for brushing in the size. With Serial No. 291,235.
ticularly advantageous in a machine of thetype of the present one, since the dirt or dust which renders a locality onthe cover unfit for further use is often shaken out more or less after the locality has been moved to inoperative position, in which case the locality may be returned directly to op-- erative position by a simple manual adjustment.
Formerly the size has been applied by means of a hand brush which was dipped into a receptacle containing size and applied to the exposed surface of the leather, such procedure resulting'in waste of the size and in non-uniform applications. In the present machine the stationary brush to which the operator presents the work receives size from a tank, the size being supplied in small measured quantities so that the right amount will be applied to the work.
These and other features of the invention will be described as embodied in an illustrative machine and pointed out in the appended claims.
Referring now to the accompanying drawings,
Fig. 1 is a view in front elevation of the upper and operating portions of a machine constructed in accordance with the present invention, parts being broken away better to disclose certain mechanism;
Fig. 2 is a skeleton view in transverse section through the head of the machine on the line 2-2 of Fig. 1 but with certain parts omitted;
Fig. 3 is a fragmentary perspective view of the oscillating smoothing wheel and the mechanisms for adjusting and driving it;
Fig. 4 is a section on the line 44 of Fig. 1 showing the liquid enamel feeding means.
The machine frame comprises the usual floor-supported standard 2 upon the upper end of which is supported a blower 4 with the interior of which hoods 6 and 8 are connected in the usual manner by a passageway which leads into the center of the blower casing. The vanes 11 of the blower are fast to a shaft 38, presently to be referred to, and are rotated-byv said shaft in a counterclockwise direction as viewed in Figure 1. The blower has two terminals 7 and 9 which face respectively in opposite directions; and a cap 5 is provided whch may be placed over either terminal to close it. With the cap over the terminal 9, the blower will suck in air through the hoods and deliver it through the terminal 7. If now the cap is removed from the terminal 9 and placed over the terminal 7, the blower will suck in air as before but will deliver it through the terminal 9. It is usual in shoe factories to run an exhaust or waste pipe along one side of a room and to arrange along that side those machines which require the removal of dust, chips or other refuse. With the construction which has just been described, the present machine may be properly placed on that side of the room along which the exhaust system is located without turning the machine around and without supplying any extra connecting pipe. It is necessary merely to place the cap 5 on the proper terminal and to connect the other terminal to the factory system.
At the front of the blower 4 between the hoods 6 and 8 a gear casing 10 outstands from the head ofthe machine and is connected with the hoods by axially offset tubular bearings 12 and 14 extending in substantial parallelism. A rotatable tool shaft 16 extends from the casing 10 through the up permost bearing 12 and into the hood 6 where it carries a cloth covered or an abrasive covered wheel 18 of suitable construction and adjacent thereto a brush 20. A second tool shaft 22, sustained in a plane substantially parallel to that of the first tool shaft with the ends of the shafts 16 and 22 within the gear casing 10 in overlapping relation, extends from casing 10 in the opposite direction through the lower bearing 14 and into the hood 8. A scouring wheel 24 is mounted within this hood on shaft 22 to turn with said'shaft. As shown, wheel 24 is formed with a yielding peripheral surface and is provided witha hollow hub 26 fastened to the shaft 22 by a set screw. This hub is extended out beyond the end of the shaft to form a handle 28.. The periphery of wheel 24, which is the smoothing tool, is partially covered by a belt 30 of abrasive material such as fine sandpaper, the upper end of the belt being carried on and guided by a flanged spool or idle pulley 32 having outstanding spindles 34, one of which may serve as a handle for inserting the opposite recesses 22 are rotatedand oscillated respectively,
through connections from the power driven main shaft 38 extendmg at right angles to the tool shafts 16 and 22 from the rear of the machine to a point adjacent to the overlapping ends of the tool shafts and within the gear casing 10, said power shaft having at its rear end the usual fast and loose pulleys, indicated generically at 40, Fig. l, driven by a belt connection 42 from the usual factory line shaft.
Adjacent to its forward end the shaft 38 carries a helical gear 44 meshing with a similar gear 46 on the inner end of tool shaft 16 for rotating said tool shaft. Beyond the hub of gear 44, the shaft is provided with spaced annular flanges 48 and an intermediate eccentric portion 50, the forward flange 48 forming the end of the shaft and lying adjacent to the second tool shaft 22. A yoke'52 has a curved lower face embracing' the eccentric 50 and a flat upper face which supports a sliding semi-cylindrical bearing block 54 having an abutment flange 56 at one end. Resting on this block is the curved lower face of an arm 58 extended forwardly and formed with a bifurcated bearing including a sleeve '60 loosely j0urnaled on the tool shaft 22 and having one end formedwith clutch teeth 62. This bifurcated member is held against lengthwise movement on the tool shaft by a block 64 fixed to the gear casing 10 and extending between its furcations; A coiled spring 66, interposed between the cover of gear casing 10 (Fig. 1) and the arm 58, serves to hold the arm against bearing block 54, and the bearing block against the flat upperface of the yoke 52 as well as to holdthe latter against the eccentric.
lit will be evident that rotation of shaft 38 will cause yoke 52, block 54 and the con tacting rear end of arm 58 to rise and fall,
thereby oscillating the sleeve 60 on the tool shaft 22. This shaft is normally connected to the sleeve 60 to oscillate. therewith by means of a toothed clutch collar 68 fastened to shaft 22, a spring 61 (Fig. 1) being employed to hold the shaft so that the collar 68 will be in clutching engagement with the teeth 62. The tool shaft 22 with the attached hub 26 and clutch collar 68 may be moved endwise in its bearings (to the left in Fig. 1) by pushing in on handle 28 to disengage the shaft temporarily from the sleeve 60 so as to permit the wheel 24 and the usual scouring wheel or belt.
belt to be turned by handle 28 to bring a fresh portion of the belt 30 over the working area'of the periphery of wheel 24 when the portion of the belt previously at the point becomes worn and ineffective from repeated scouring oscillations. It should be particularly noted that after the teeth 62 have been disengaged the handle 28 may be turned to any extent in either direction so that any selected locality on the belt 30' may be brought into operative position. It is thus possible to pick out any selected locality on the belt and bring it immediately into operative position. It should be noted too that the oscillation of the wheel 24 imparts to the working portion of the belt a motion which simulates closely the hand operation of rubbing back and forth, such a movement having been found desirable to produce the desired result.
It frequently happens that the cracks appearing in patent orenamel leather of the toe portion of a shoe, for example, extend to the belt crease and cannot be reached by I have therefore provided a small abrasive hand tool which is arranged to .be power operated, the power actuated connections being such that the tool is disconnected from 37? the power drive when the tool is not in use. To this end a journal block 70 (Fig. 2) is fixedly secured to the upper part of the casing of the blower 4 and is formed with an opening adjacent to its front end.
' A hearing sleeve 72 extends from beyond the rear end of the journal block through a bore in the block to the rear wall of the opening therein. A shaft 74 is journaled in the sleeve and has its front end projecting into said opening and socketed to receive and rotate the squared end of a tool spindle 75, which, forwardly of said squared end is journaled in the front end of the block and connected by a flexible shaft 76 to the spindle 78 of a rotatable hand tool 79 which, as shown,'consists of-a small disk of abrasive material.
The socket in the shaft 74 is of a length to permit lengthwise movement of the shaft relatively to the end of the spindle 7 5. YA pulley 80 is mounted and freely rotatable on the rear end of the sleeve 72- and is constantly driven by a belt connection to, a
The forward end of the shaft 7 4 extending within the opening in journal block 70 and shown in section in Fig. 2, is reduced in diameter providing a shoulder and has its extremity threaded. A collar 92 is mounted on the reduced end of the shaft between flange disks 94 of relatively large diameter, a nut 96 screwing on the threaded end of shaft 74 crowding the rearmost disk against the shoulder of shaft 74 and clamping the disks and collar to the shaft. A loose ring 98 con centric with collar 92 is confined between the disks 94 and at diametrically opposite points is engaged and held between set screws 100 threaded into bores in the lower ends of legs 102 formed as downward extensions of the bifurcated arm 81 and located below the pivot 82 of said arm. The sleeve 98 has a loose fit over the collar 92 and does not rotate with the collar and shaft but may move them longitudinally since it is confined between the disks 94. When the operator drops the flexible shaft on the crossbar of the bail 86, the forward end of arm 81 is automatically swung downwardly and the legs102 and sleeve 98 are swung rearwardly as shown in Fig. 2, thereby sliding the shaft 74 rearwardly to disengage clutch disk 84 from pulley 80. When the operator picks up the hand tool for use and thereby removes the weight of the flexible shaft and tool from the bail. the spring 90 automatically swings the arm 81 in a reverse direction; and, through the sleeve 98 and disks 94, slides the shaft 7 4 forwardly to bring its disk 84 into clutching engagement with the continuously rotating pulley 80.
At one side of the machine head, a bracket 104 (Fig. 1) extends upwardly and supports a reservoir or tank 106 in which liquid size is stored. At the lower end of the tank an outlet opening is provided to receive the end of a curved discharge pipe 108 which The rear end of the arm 81 is prois provided with a collar having laterally extending plates 110 formed with notches in their edges. Bolts extending from the face of the tank are received in these notches,
, and wing nuts 112 engaging the bolts clamp posed between this brush and the upper end of the discharge pipe, is a manually operable feed Wheelshown in section in Fig. 4. The valve casing 116 is suitably bored to receive and journal arot ary feed wheel 118 having a pluralilty of size receiving pockets at any should be 1 5 p with the liquid Size 120 formed in its periphery. A spindle extends outwardly through the casing from this feed Wheel and is provided with an opcrating handle 122. By giving successive partial turns to handle 122,the operator may cause successive pockets 120 to feed the size therein to the brush 114 as it is needed. The pockets 120 have very limited capacities so that only a small amount of size is delivered time. In this connection it should be noted that the diameter of the pipe 108 and the spacing of the pockets is such that only one pocket is in delivering position at any time. It is desirable that the brush 114 since only a small amount should be applied to the work and the feed mechanism which has been described above, by permitting the feed of small quantities only of the size,
furnishes a satisfactory means for keeping bounded by abrupt shoulders.

There is left, however, a short nap which should be laid; and the surface of buffed leather is always some- The smoothed surface is, therefore, presented first to the brush 114, to receive a small amount of size, and then to the rotating brush 20 which lays the nap and brushes in the size. The surface to be memos re-coated with enamel is thus smoothed and cracked tips of enameled shoes forthe reenameling operation, 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.
