- i-ipoint at Which the-staple should beinserted'i f'i and'carefully to press together the parts of, I the-shoe through ivhich' the staple was to bev dri-ven To this end the machine shown I "in said Letters Patent I isprovided with} '60 means" for" preventing more than one pelation-of the inserting mechanism for one] clamping and actuating movement of thev "manually controlled means and [the relative clamping movementof the staple guid 55 I andthe staple clenching anvil is 'eii'eqted manually, It is found practice, however, that to require; the operator to; start the machine every time a staple is to,

pac'ity of theope'rator and that, moreover, -toreguirethe machine to stop and .to be a "started" for each staple inserting. operation '"caiises very serious Wear and tear of the ;machm'ef 'andlikewise reduces its poss ble .75

"c pac ty-1 a i a 'impor'tantobject of the invention is 3 o to construct the machine that the clampng of the parts through which. the staple s t' o be inserted may be effected automatiiallyi 'and that by a single actuation a plurality offstaple inserting operations may be eti'ected,.the clamping mechanism being Q 4 so constructed: and operated that the op- '1 elfatorj may locate the shoe with sufiicient 85,

accuracy. for the purposes of the machine between: the successive clamping and in .serting operations. v q 1 AfpaItiCulaI' object of the invention is so to arrangethe automatic clamping mech- 90. anisn that the parts throughWhich' thestapleis to be inserted may be automatically I clampednabovethe-line of insertion in a movement of Ithetreadlelactuateslthemeelicertain time relation to the additional:

condition, it Was assumed in designingfthi si machine that to avoid the insertion of o'ne Y staple on top of another in casetheoperator did not remove his fobtifromfihe treadle quickly enough, it would be necessary to provide means for preventing the machine from repeating and in any event it would be necessary carefully to select the Inasmuth' as the.

clamping-action exerted upon these parts below :the'line of insertion, provision being p'referably made tor varying this timing.

., )ther objects and important features of the invention Will appear from the follow 'ing description and claims When considered in connection with the ings, in which,

Figure 1 is a perspective viewpf the up' per part of a machine embodying the in- I vention ;'*Fig.@2 is a vertical'sectionthrough the head of the machine, illustrating the accompanying draW- operative cgnnections by which the aut0- matic movement of the staple clcnchinganvil is eitected; Fig. 3 is a detail view, showing portions of the connections between the being mounted upon a standard 8 which is treadle and the clutch which are concealed in the other figures. 4 a

The principal operative parts of the machine are substantially identical with the corresponding parts of the machine shown in the Letters Patent No. 1,059,984, above referred to, the cams from which the various mechanisms are operated being connected to a main driving shaft 2 mounted in bearings 3 in the head 4 of the machine, said head carried upon a base, not herein shown, in which base is located a treadle, also not shown, through which the manual control 5 of the actuation of the machine is effected.

A driving pulley 10, loosely-mounted upon the shaft 2, is arranged to be clutched to the shaft at the will of the operator by any suitable clutch mechanism, the clutch herein' illustrated beingof'the Horton clutch type. A clutch controlling arm 12 upon a rockshaft 14' normally holds the clutch in its in' operative condition, the roller cage 16 of the v clutch being provided with a stop portion '18 which normally ehgages a spring-cushioned" 1 dog 20 pivoted between ears 21-upon the end v of the arm 12. -When-the shaft 14 is turned (in a clockwise direction in Fig 2, the dog 20 v is lifted out of engagement with the stop 18 and the roller cage 16is rotated-by a spring, not shown, in the usual manner to bring-the usual rollers of the Horton clutch into clutching. position betweena clutch memher fixed upon the shaft 2 and a cylindrical surface upon the inside of the pulley v 10; A spring 160 tends to maintain the arm I '12 normally in its clutch releasing position.

The brake arm 32 is also carried bythe rockv shaft 14, surrounding an eccentric upon said shaft and being moved into and out of engagement with the brake disk 30 by said eccentric as the rock-shaft is oscillated during the clutch -releasing*and clutch actuating movements of the lever 12.

The sta le formin and i sertin mechap b t nism. comprises, as 1n the machine of said Letters Patent above referred to, an outside former 34 arranged to slide in a guideway in the machine head, said outside former carry ing at itsforward end a tongue 42- which projects in front of the former and engages v the work ust before'the staple is inserted'to I press together close .tothe line ofinsertion the parts through;which the staple 'is .to' be inserted. The outside "former {is provided upon itsupper rear face with rack teeth 48 which mesh with teeth 50 of a segment rack carried by alever 52 fulcruriied upon a rock-shaft 54 and having upon its j'otherarm 56 a cam roll which enters a cam groove 57 in a cam disk58 uponlthe main shaft 2. The outside former cooperates to form a staple with an inside former 60 carried upon a vertically movable plunger 62 having at its upper end a slotted head 64 through the slot in which passesa bolt 66 carried by an arm 68- 'upon a rock-shaft 70. A spring 72 surrounding the hub of the arm andbearing against the upper sideof the head 64 tends to keep the end ofthe head 64 in engagement with the bolt 66 but permits lost *rnotion.

after the inside former has come into v its proper opeplat' veiposition, the staple formed about said I driver 106 connected. to the driver slide 118,

s d' former being driven by av -all as more fully described in said Letters Patent above referredjt The wire 84 from which the staple is to "in formed is fed into position to be operated upon by the staple formers by feeding means comprising a toothed feed wheel 86 against which the wire ispressed by a spring-pressed presser ,roll

.88 geared to the feed wheel 86, said feed wheel being rotated through a pawl "and ratchet mechanisnnmore fullydescribed in said Letters Patent, said pawl and ratchet inechanism being operated by a link connected to the arm 76 of the means through which the inside forinris operated. x I

The rock-shaft 14 which carries the clutch linkibeing provided with a hook 150 at its lower end and entering a slot'in an arm 144 controlling arm 12 is provided with a second i arm 154 from which depends a link 148, said attached. to thefr'ock-shaft 164. The link .146 which. extends to the treadle is connected at its upper-end to the arm 144 and a pin 152- in the slot in said arm 144 is adapted to be engaged by the hook 150 when the'link, 146

pulls said arm 144 downwardas the treadle is depressed. The rock-shaft 14" is thus rocked to throw the dog out-of engagement chine of this inventiomseveral of these parts being retaihedin the illustrated construction for convenience 1n adapting the machine for operation in the manner of the machine describedun the Letters Patent above re ferred'to in the event that suohj pp erationf of themachine, is desired. The machine herein shown,'like the'inachine of said.-

Letters iP atent, is timed to insert a staple during the firstpartof the cycle of operations and then to form a staple and to stop withthe staple formed;v lny orders that the "staple clenching anvil 123 fay, be brought into ,work clamping i'elatio iil guiding nose.l22 in time to 1 the parts through which the t driven, this anvil is shownlas perated by connections to the mechanism which operoth'e staple imp together ple is tobe ates the outside former and; the tongue 42- whereby the-tongue 42 engages one side of the; parts through which the staple is to be inserted ina certain time relation to the enga ement of the other side of said parts by l A the a'nvil l23. The anvil 123, afsin the ma- 5 chine shown "in said Letters Patent, is 'carriedlby a slidelQ iwhi'ch slides in a guideyjforked extension 132. embracing a lever arm H ,1, l62iiponfthe rock-shaft 16%,said arm being 1. connected atits end. remote from said shaft to an extension 166 of the lever arm 56 by meanso'f link 1.68 forked at each of. its

end made in two parts having a threaded" onnecti'on whereby the length of the link ay'be var ed, said} parts being locked in theirfdifierent adjusted relations by a set j'Ijhelength adjustmentjust described pro- 1e clenching tool or anvil 123 and the nose "Q12 :TOQproVide for an adjustment. of the mount of. clamping movement imparted to theelendhing tool 123, the extension 166 of the lever .56 i s-"provided with a series of r-dekhaft 54 whereby the pivot pin 174; by which the link 168is connected to' the extenslion 166 may be located at difierent dis-' tances from said rock-shaft. To provide a yielding clamping action, a spring 138 surrounds the bolt 134 and is confined between 35. the upright 136 and a nut and Washer upon the threaded end ofsaidbolt. In order to provide both the requisite tension and the requisite compressibility, the spring 138 is made in two parts, as shown, one being 40 within theother.

The operation of the machine will be apparent from the foregoing description. It will be seen that when the operator depresses the treadle to start the machine atter the lasted shoe has been presented to the anvil 123 or to the nose122in proper posh tion to receive the first staple,'the anvil'will be automatically brought into work clamping relation to the nose and so long as the 0 operator keeps his foot upon the treadle' the anvil will be moved into and out Of'WOIk clamping relation to the nose, being =moved into Work clamping relation just before the staple is inserted and out of Work clamping relation just after the staple is inserted. By connecting the anvil up to the outside former this movement into and out of'work Q clamping relation requires only a small part of the time consumed in the cycle of opera tions of the machine, since the machine stops' with the staple formed, and, therefore, the

vides I-forvarying the. normal separation of j holes 172 at different distances from the toward and away from said nose, means for chance, the operator should have located'the shoe so that the staple is driven against one of the lasting tacks, no harm will be done owing to the yieldingconnection between the anvil and the outside former and ow- I ing to the fineness of the "wire from which the staple is formed, the staple being merely it is found in.

that the staple will be driven through the "parts to be united and clenched upon the anvil. 1
