Application filed October 2, 1920. Serial No. 414,224.
To all whom it may concern:
Be it known that I, THOMAS DURRANCE, a subject of theKing of England, and resid: ing at Leicester, Leicestershire,England, have invented certain Improvements in Work Supports, 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 operating upon boots and shoes and more especially to work supports, and is disclosed for illustrative purposes as embodied in an automatic edge setting-machine of the type described in United States Letters Patent No. 1,078,684, granted November 18, 1913, on the application of Keall, Gouldbourn and Jerram.
Prior to the present invention it was the custom, in using machines of the type above referred to,'to clamp thetoe of the shoe in proper position up'on theforepart support by means of a forepart clamping mechanism, and then to bring up and set the heel clamp. WV'hile this mechanism Was Well. dcsignedif-or the purpose for which it was intended, certain conditions- 0f work, or carelessness or lack of skill on the part of the operator sometimes"prevented the production of the best results. The operator might fall to aline the shoe exactly with the heel clamp, which would tlren contact with it only at one side of the heel,frequiring a second trial to set the shoe properly. Furthermore, the double clamping-operation sometimes required more time than was convenient, two of these machines being run by the same"operatoiywho set a shoe in one while the other was setting the edge of a second shoe.
It is therefore an object of the present in- Vention generally still further to improve shoe jacking mechanism, by providing" an arrangement insuringthe proper location of a shoe, for example, in machines of the type referred to, in one accurate and rapid operation. a r
I have therefore provided 'a novel organization of forepart clamping, and 'heel clamping members constructed for dependent settin in one'ope'ration. This doesaway with the double clamping-operationhereto tore practisedjand has proved to be very economical of time. Preferably the mechanisrn is organized so that a single movement of the lever controls thepos'itlomng ofboth clamp ng members, and m the machine shownthere is provisionfor timingso that one clan'iping member is set just before the ranged to operateatla station, a heel clampingmember arranged ,for movement under pressure of the shoeas the ;operator adjusts the shoe at thejstation, and a setting ,means for the h'eel clamping member operated in connection with a forepart clamping memlfhese and other features of the invention comprising variouSv Combinations and arrangements of parts will be understood from the following cleser ption of an embodiment thereof in connection wy-ith the automatic edge setting-machine above mentioned, and shownin the drawing, I i a In the disclosed ei nbodiment of the invention, the fork 10 which, in'the machine describedfin'the patents referred-to, is customarily providedto "engage the heel end "of the shoe is, as usual, mounted for longitudmal adpistment by a clamp 11 in a sleeve l2 itself mounted to slide longitudinally in so other-,thus'permittingfthe operator to make an opening 14 in Ithe jack frame 16. A light spring 18 is provided tohol'd the sleeve ,nor-
madly in forward positionwith the fork projected' beyondthe positionit will occupy when in clamping engagement. with the shoe. The upper surface gof the sleeve has formed upon it a ratchet 20 adapted to 'be engaged by'a pairofjpawls 22 piyotecl on the jack frame and (set half the length of one of the ratchet teeth;apart.v Ligl'rt springs 24 housed in the jack frame press upon the pawls and urge them into engagement w th the ratchet the teeth of which are directed so that fwhen either of the paw-ls isv insengagement with the teeth of the ratchet the p fork is locked against rearward move ment. The pawls are provided with tails 26 in juxtaposition under the end of an arm 28 of a bell-crank lever pivoted on the jack frame, said arm being broad enough to-engage both tails.
@ pressed plunger 32 to urge the bell-crank the toe clamp actuating mechanism 38 customary in the machine referred to. The toe clamp mechanism employed may be that detailed in the United States Letters Patent No. 1,153,928, above referred to, and the ex tremity 39 of the'rod 34 is in the vicinity of the lower end of the actuating lever 40.
The construction and arrangement of the parts is such that when the operator places in the heel fork 10 and moves the shoe backwardly against the spring 18 with its heel end in the fork until the shoe attains the position which he considers to be the correct one. The operator then by movement of the actuating lever 40 of the toe clamp mechanism brings the toe clamping member to bear upon the top of'the shoe at the back of the toe and just before the final clamping pressure is applied-by the toe clamp mechanism the actuating lever bearing on the extremity 39 of the rod 34 moves it back wardly sufficiently to swing the bell-crank lever 28-30 clear ofthe tails of the pawls to allow one of them to drop into the ratchet and lock the heel fork against rearward movement. The rod 34 is made adjustable in length as at 42, in order to effect accurate timing of the two clamps or holding members 10 and 38. The operator, just after the fork 10 has been locked, and before the clamping member 38 hasbeen set, will push the shoe'back firmly into the fork 10, and then, with a final short movement of the lever 40 will set the clamping member 38.
The tool carrying head 44 and the guiding and operating mechanism thereof and of the jack axis 46 are described in the Letters Pat-' out above referred to" and need not be further noticed here. i 1 c Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1.'In a machine of the class described, a
proper relation to an operating tool, and interconnecting mechan sm controlling the positioning of said clamping members.
The other arm 30lof the iell-crank lever is acted upon by a spring- 2. In a machine of the class described, a support for the tread face of a shoe, a forepart clamping member, a heel clamping member, andan operating lever constructed and arranged to'move one of the clamping members to clamping position and to lock the other against movement.-
3. In a machine of the class described, a
.support for a; shoe, a forepart clamping member and a heel clamping member, means for locking the-heel clamping member, and an operating lever, said forepart clamping member being arranged for operation by the lever in timed relation to the locking of the heel clamping member.
4. A. machine according to claim 1 in which the interconnecting mechanism is arranged for relatively. timing the final positioning of theclamping members to permit a final adjustment of the shoe againstone before it. is finally clamped by the other.
' In a machine of the class described, a
support for the forepart of a shoe, a heel .clamping member, means for automatically a shoe 1n the ack he first places its heel end variably positioning said member with respect to the forepart support, and an operator controlled forepart clamping member operable to clamp the forepart against the support.
6. In a machine of the class'described, a support for a shoe, a heelclamping member constructed and arranged to be positioned under pressure exerted by the shoein the hand ofthe operator, a forepart clamping inginember before setting the forepart cl am ping member.
8. In a machine having .a tool constructed and arranged for operation on a shoe and a jack arranged to support the shoe adjacent to the tool, a heel'clamping member arranged to support the heelend of the shoe and movable correspondingly to the shoe length, to permit adjustment of the shoe relatively to the tool, a forepart clamping member, and means for operating the forepart clamping member and locking the heel clampingmember. I
9. A machine according to claim 8 in which the. operation of the locking means and the operation of the forepart clamping member are-relatively timed.
10. In a' machine of the class described, a V-shaped member arranged to support the heel end of a shoe, and to slide resiliently to operative position under pressure from the shoe, a support for the forepart upon which the shoe may be adjusted by permissive movement of the said V-shaped member to place the toe in desired position, a toe clamping member to hold the shoe rigidly to the support, and a locking means for the V- shaped member constructed and arranged to arrest the sliding movement and hold the member firmly against pressure, operated in time relation to the toe clamping member by a single effort of the operator.
11. In a machine of the class described, a support for the sole of a shoe, a forepart clamping member for securing the forepart of the shoe to the support, a heel clamping member mounted to slide under pressure from the heel end of the shoe, and mechanism controlled in the movement of the forepart clamping member for looking the heel clamping member in position.
12. In a machine of the class described, a support for the sole of a shoe, forepart clamping means for holding the forepart of the shoe against the support, a heel clamping member for engagement With the heel end of the shoe and having a slidable stem, a spring pressed pawl for locking the stem, means normally holding said pawl out of locking position, and mechanism controlled by the forepart clamping means for releasing said holding means.
In testimony whereof I have signed my name to this specification.
