MACHINE FOR ORNAMENTING SHOE PARTS Filed March 27, 1930 4 Sheets-Sheet 4 Patented Dec. 8, 1931 PATENT OFFICE ARTHUR W. ALTVATER, OF UNIVERSITY CITY, MISSOURI IVIACHINE FOR ORNAMENTING SHOE PARTS Application filed march 27, 1930. Serial No. 439,308.

, This invention relates to machines for ornamenting shoe parts. 7

In theembodimentof the invention shown in the accompanying drawings, the machine 5 is constructed and designed for operating on shoe parts arranged flatly upon an appropriate support, or to operate upon completed shoes and fitted shoe uppers having the parts thereof that are to be cut or trimmed or ornamented located upon the support preparatory for and during operation of the cutting, trimming or ornamenting devices.

The invention also comprises ornamenting devices supported above the support, in com- '5 bination with means for pressing the cutting, trimming or ornamenting devices against the shoe parts that are to be ornamented, so that said cutting, trimming or ornamenting devices function as gages whereby the operator is guided in locating and positioning the parts that are to be ornamented. This machine may be operated to trim and cut-out the linings of completed shoes to correspond with previously formed cut-outs in the uppers of the shoes, when the linings were left Without cut-outs in the shoe uppers in order to reinforce and prevent stretching and distortion of the shoe uppers during the lasting and finishing operations. In these operations of trimming and forming cut-outs in the linings of completed shoes to correspond with previously formed cut-outs in the shoe uppers, the cutting edges of the dies are located in the cut-out openings or holes in the shoe uppers by preliminary manual operations of the dies, after which the dies are positively driven to cut through the linings of the completed shoes alongthe edges of the cut-outs or holes in the shoe uppers in which the dies had been inserted. In these operations, the dies function as gages'to guide the operator in the location of the shoe uppers and completed shoes, by placing the cutting edges of the dies Within the correspondingly shaped cut-outs or holes in the shoe uppers. The machine also comprises mechanism for forcing or driving the ornamenting devices properlyto produce the desired ornamentations upon or in the shoeparts after the shoe parts have been located and positioned as above described, or otherwise.

The machine also comprises means for adjusting the ornamenting devices in proper relationship to the operating mechanism therefor and to the parts that are to be ornamented and the support upon which said parts are mounted. Thus, the machine comprises means for adjusting ornamenting dies in position to cut entirely through the shoe parts, or to produce demarcations upon or in the surfaces of the shoe parts, as desired. I

Objects of the invention are to produce a machine embodying any or all of the .foregoing structures, devices and mechanisms, and also to provide a machine that possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description, reference being made to the accompanying drawings, in '10 which Fig. 1 is a front elevation of my improved ornamenting machine.

The machine shown comprises a rigid frame constructed andarrangedto be'located I in a rigid position, so that the machine will iiotfcreep or move from ts proper location urin oaera'io' oe' ra' e i d g 1 t 11 T1 t m shown com prises a base 1 from which the upright frame 3 part 2 rises. A bearing 3 formed or sup-- ported at the upper end of the upright frame member 2 and constitutes a journal for a ro- 'tary shaft'4. A wheel 5, constituting a power transmission element; is mounted on one end of the shaft 4 andmay be constantly-rotated and controlled,fso asto rotate the shaft 4 intermittently; This power transmission element 5 may rotate while the shaft 4 remains stationary, and may be caused to rotate the shaft intermittently and at any desired'intervals by any appropriate clutch device.

The complete clutchdeviceis shown in :my

companion application Serial No. 334,934, filed January 25,1929, and" comprises ashding cl utch'member 6 movable into and out of a notch? in the hub 801. the power transmission device5. The clutch member 6 is slidable in a slot 9 in a collar 10 that is I rigid on the shaft 4. A spring 11 presses the clutch member 6 to clutching engagement in the notch 7, and said clutch member may be disengaged by a wedge lever 12 pivoted on "a support 13 and operated by a link 14.

" 4, but the ring 16 does not rotate;

17 is embraced between .a pair of arms 18 extending upwardly from a sliding plunger 19. 'Theslidingplunger 19' is mounted in a guide during operat on.

-Thiscomplete clutch. device is clearly disclosed in-my'said companion application, and

the details thereof are notherein claimed. -Therfront end of the shaft 4 has attached thereto an eccentric which rotates Within a ring 16 havinga downwardly extended arm 17 *Theeccentric15 is rotated bythe shaft The arm 20- rigid with a forwardly extended portion 2110f the framemember 2. VA plate 22is attached to the guide 20 by screws 23 and forms the front portion of the :guide'so as to prevent the plunger 19 from oscillating'improperly My inventlon comprlses means'tor varying V the eflective length of the plunger the 7 same "comprising a block 24 havinganaxial extension 25 l which isscrewed into the lower end of the plunger The block 24 1na y be turned in either direction, as required to extend or reduce the effective length, of the plunger 19. By turning the block 24 in a direction toscrew the stem 25 outwardly, the cttective length of the plunger is increased and, by reversing the direction of rotation of the block 24, the effective length or the plunger reduced- The screws 23 may be removed to permitremoval of the plate 22, so as to atford access to all of the parts mounted in the guide 20. 4 j 1;

A' die carrier 26 is mounted for sliding movements in the guide 20 in axial alinement with and below the plunger 19. The lower 'end of the carrier 26 is below the lowerend of the guide 20. The carrier 26 has pins 27 p'roj ecting' from the side thereof throughslots 28 in, the sides of the guide 20. These slots 28'are of sufiicient vertical length to permit all desired longitudinal movements of the die carrier 26. Springs 29 have their lower ends engaged With the pins 27 and their upper ends engaged with pins :30 that are rigid with the sides'of the guide 20. The energy of these springs 29 is exerted and utilized to support the die carrier 26 yieldingly in its upper po-' sition, andto move said die carrier to its upper position after each operation thereof by the plunger 19. I

My invention comprises means for varying the efi e'ctive length of the die carrier 26, to provide for operating dies on work of different thicknesses and to provide for adjusting the die carrier so that'th'e'dies will not be damaged by any variation in length thereof. The upper end of the die carrier inclines downwardly and forwardly ig. 3) and constitutes a support for a block 31 having its lower. side incli'ned'the same as the inclination of the upper 'endof the die carrier 26, and having its upper surface fiat andat right angles to the axis of the die carrier 26 and the" plunger 19. A screw '32: is screwed into a threaded hole 33 formed in the die car- 'rier 26 below and parallel with the inclined upperend o'fthe die carrier. V A knob or handle 34 is rigid 'with the outer end of the'screw 32 and constitutes meansfor rotating said screw in both directions. The screw 32is unthre'aded for "a distanc inwardly from the knob 34,-and'said unthreaded portionis rotative, within a bearing in an aria-35 extending downwardlyfrom theouter end of tlie block 31. A collar 36 "is rigidly secured to the screw 32 at theinner side of thearm 35'. This construction provides means for permitting rotation of the'screw 32 in the bearing-Term 35 and for preventing the screw'frommoving longitudinally, with, respect to the bearing i arm At the same time, the screw. 32 is permitted to -bescrewed into or out of the threaded hole- 33 so as to slide the block 31 along the inclined upper end of the die carrier 26. It is clear enough that when v the block 31 is moved inwardly,f sai d{block is raised by I the effect of the inclined surfaces of the die carrier and the block so as to increase the effective lengthof the die carrier; and when the block 31 is moved outwardly, the eifective length of the die carrieris reduced.

The block 31 has therein a recess 37 enclosing a spring 38 and partly enclosing a latch member 39 which is projected outwardly so as to engage in any one of a series or" indentations 40 in the inner surface of the knob 34. Thus, the part 39 constitutes a latch for pre venting the knob 34 from accidentally turning, but permitting manual rotation of said knob to operate the screw 32. It is now clear that the knob 34, and thereby the screw 32, may be freelyrotated manually, so as to adjust theblock 31 to vary the effective length of thecdi'e carrier 26, as required to obtain proper adjustments for dies having varying length and for other purposes. This adj ustability of the efiective length of the die carrier 26 is highly desirable, as it avoids the; necessity of making the dies with the great precision that would otherwise be required. This the carrier has extending upwardly in its lower end a pair of spaced parallel holes 41 intersected .by a transverse hole 42 formed between said holes 41 intermediate of their upper and lower ends. The holes 41 are designed and intended to receive the clutch extensions 43 projecting from one end of a die body 44 having its upper end abutting against the lower end of the die carrier 26.

Each of the clutch members 43 has in its inner side an arcuate notch 45, which notches are concentric with the hole 42 when said clu'tch'niembers 43 are extended into the holes 41 and the end of the die body 44v is against the end of the die carrier 26 (Fig. 10). The hole 42 contains a clutch device which is operable into'and out of clutching engagement with the clutch members 43.

This clutch device comprises a stem 46 having a diameter less than the distance between the holes 41', so that when said stem 46 is -between the clutch members 43, said clutch members are not engaged by said stem 46. One end of the stem 46 extends through a hole of reduced diameter at the inner end of the hole 42 and is thereby guided in its longitudinal movements. Ascrew '47 is screwed into the inner end of the stem 46 and'constitutes an abutment to stop and limit outward movement of said stem 46. The front end of tween the clutch members 43, said flange is the screw 47, in which position the flange 49 is in clutching engagement with the clutch members 43 of the die element. To release the flange 49 from clutching engagement with the clutch members 43, it is only necessary to press against the knob 48 of the stem 46, and

thereby move the stem 46 inwardly until the flange 49 is beyond and out of engagement with the clutch members 43. Then, the die member may be removed from the die carrier and another die member attached to the die carrier.

The die member 44 is a frame havingrigid with its lower end a die 51 for cutting through or into the parts to be ornamented, or For producing outlines upon or in the surfaces of the parts to be ornamented. This die may be equipped with a stripper plate 52 having therein an opening 53 through which the die edges 54 may be extended to ornament the shoe parts.

supported by pins extending for sliding movements through the body of the die 51. Springs 56 encircle the pins 55 and actuate the stripper plate downwardly. Extent ot. movement of the stripper plate by the springs 56 is limited by ahutmeuts 57 in connection with the pins 55 engaging the upper side of the die 51. This stripper plate may be constructed and arranged so that one or more of the edges thereof may be brought into registration or engagement with edges or outlines on the parts to be ornament ed, so as in guide the operator in locating said parts i'or operation of the die. Or the die may be equipped with gages 58 actuated downwardly beyond the plate 52 by springs 59. Extent of moven'ientot the gages 58 by the springs 59 is limited by abutments 60, which may be removed to permit detachment and replacement of the gages. In this embodiment of the invention, the gage for the parts to be ornamented is supported by the die. V

The frame member 2 supports a rigid arm 61. The arm 61 projects torwardly a considerable distance below the forwardly'extended frame part 21 and to a distance beyond the plane of any dies that may be mounted on the die carrier 26. arm 61 constitutes a support for removable and replaceable and interchangeable anvil heads 62, whicn may be of different and selected widths as required to support work of different sizes and shapes.
