To. all who-m 'it may concemr v Be it known that I, Lon'rs A. CasonAIN, a `citi'/.en;of the' United States, residing at Beverly, in the county of Essex and State I@ of Massachusetts, have invented certain Inip'oveinents in Mrk-Supports, of which the following.description, in connection with vthe accompanying drawings, is a specification,like reference characters on the draw- 119 ings indicating like parts in the several figures. a f

This invention relates to work .supports .for fastening inserting machines of the ,character :employed-:in the manufact-nre of lo boots andyshoes.

, to severe strains; but. the action of the shank It is an. important object of this invention to provide a Work'l support for a machine of the character:referredto:by means of which fastenings k,niayibe .inserted along the. mars2() gin of a :shoe sole.f

frequent y-happens,rafter 'a shoe has been worn for sonicftime,.thatthe stitches of the ;outseamibreak-xiirthe shankand thus allow the routsole vto.,split-away from thewelt.

- This resultis-due chiefly tothe fact that the constant.'bending-.ofthe shank portion of the solev during -.wearfsubjects the stitches stiti'en'er also contributes to this end since it .35 Aprevents the distribution ot' the bending' movement, over the entire. shank and tendsto concentrate the bending vat each end ot' the s titl'ener, particularly at the end near.

tlie'jiini-.tiire of the shank. and forepart.

4C liniftherniore, the shank stitener tends to press the outsole away i'ron'i Athe insole and the welt. lt has been proposed to reinforce A the outsoani -to.preveiit the splitting of the outsole away-from the i'velt as described by V placing a line of fasteniiigs along the shank.

'llie double clencl fastenings handled b v the machine shown 1n the United States atents` No. (369,023, dated Feb. 26, 1901.

and No. -lflhtit dated-Feb. t8, 190.2, are

United States Patent No; 693,686 and reference should he made thereto for a detailed descriptin 'of the construction and-operation of the fastening inserting mechanism. As

--to the post 2 near its lower end by bolts 10,

the post having a transverse groove formed therein to. receive a tongue 12 on the bracket.

l14. connecting'said arms.

'.By this construction the bracket Ais adapted to fit onto the post in place of the regular horn. The bracket. comprises two arms extendinglforwardly and upwardly and a rib Supported in the forward` ds of the bracketarins is a pivot bolt 16, retaine iipbsition by suitablcaiuts and washers, anda work sustaining lever 18 of bell crank frin is pivoted on and is adjustable axially of said bolt. A draw bolt 20 extendingthroi'igh the lever and engaging the :bolt 16 (see Fig. 3) serves to secure. the

levertirmlyin adjusted position. The forwa'rd endv offtlie bell crank lever has a hole s drilled therein and its lower side is,slitted longitudinally to form a .clamping portion in whicli'a ivoik engaging tip is adjustably Vsecurely in place.

` The work engaging tip comprises a body portion received,- a bolt 24 serving topelainp the tip 22a shank 26 extendiirY therefrom a. :a and an. adjustable plate 28 secured on the iipper' side vof the body portion by means of a screw 30. One or more dowel pins extendfing into'holcs 32 in the plate 28 preventthe .plate from turning. The plate as shown in the drawings is of pentagonal form with its corners rounded, but it. may be circular or of any other suitable shape. A plurality ot' elenching cavities 34 are formed in the upper face of the plate, one cavity being located adjacent. each corner, and as one cavity b cconies worn another may be adjiisted'ili Operative position under the work abutment 36 ot' the fastening inserting mechanism by merely loosening the. screw 3U and changing the angular position of the late. ln order that the fastenings may be inserted close to the stitches in the shank ot' the shoe, the plate 28 is formed with a 'rela-A tively thiii lip .projecting entirely around its lupper edge, This lip may be forcedinto the crease between the sole and upper of a shoe as it is p`l`aced'sole upward on the work supporting tip so as to bring the clenehing cavitiesl very close to the line ot' stitches;

and the plate is cut. away below thc lip-so as not to interfere with the upper of the shoe.

Moreover the-polygonal shape ot' the plate permits the operator to rock the shoe about vthe rounded corner adjacenteai-h cleneliing eavityto position the shoe correctly t'oithe driving ot tzhe lastenings 'l`h'e lever 18 and tip 2.2 are normallyheld in the position shown in full lines in Fig, 1, by a hitch pivoted to the rearmostend of the 'lever.`

the screw 44 by a coil spring also positioned in the recess and operates to prevent 'acei dental turning of the adjusting screw.- It

will be clear from Fig. 1 that turning't-he screw 44 in or out will result in raising or lowering' the. tip 22. The latch is -also provided with a second arm 48 `that norsoy nially engages tliestop 50 projecting laterally from an arm 54 operated from l'the fastening inserting mechanism. the position shown in Fig. 1, with; its-arm 48 engaging the stop 50 andthe adjusting screw 44 abutting againsttherib 14.by a

spring 5G connected at. one end to the hitch -v and at its opposite end toa stationar v bracket 58. When the latch is tripped by pressing downwardly on the serew- 44 oi'- oiie end of -which is mounted on the pivot bolt 16 andthe `other end of which pivotally connected to a rod The hitchl is normally heldin member-46, the spring. 56 turns the bell crank lever and latch about the pivot bolt. 't6

'into the position indicated by the #dotted lines in F ig. 1. The work support is then in convenient position for thel workman to make adjustments either to the support itselfoi' to the fastening 4inserting mecha nisni. The hitch may be returned to its op; erative position by merely raising the tip 22, In order-tokcep the lever 18and arm 52 in a constant axial relation to each other the hub portion of the ai'm is provided with a boss (30 having a guideway formed therein to receive a shouldered projection 62 on the lever 18. As the lever is adjusted axially of the pivot 16 the arm 52, therefore, mustl move with it. Lnliricating material may he supplied to the pivot bolt. 1G through' the holes` (tlormed in the bracket arms'S.

Tt will be clear that by means otv the vari. ons adjustments above described thework engaging tip may be moved in a'iiy direction necessary to position the elenching cavities accurately with reference to the work abut,` nient 36.

In operation, the rod 56 is moved in timed relation to the fastening inserting operation,

and this movement is transmitted through the arm 52, stop 50, hitch arin 48 and lever 125 1S to the tip 22 to clamp the work firmly bei' tween the plate 2S and work abutment 36 during the period n which the.fastening is being driven and clenched. Between -the inserting of successive fastenings, the rod 5l is moved upwardly and-the spring 56 I '.-operates through thev lever 18 to lower the work engaging tip and permit the operator 899,093, dated September ing said lever movements to cause it to.A

t0 lfeed the work over the plate 28 into posiltion for receiving the next fastening.
