Application filed July 13, 1915. Serial N0. 39,599.

To all whom it may concern:

Be; it known that I, PEARL J. Wnn'rwon'rn, a citizen of the United States, residing at Newport, in the county of Campbell and State'of Kentucky, have invented certain Improvements in Side-Lasting Machines, 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 which are especially adapted for use in connection with the lasting of boots and shoes and is herein shown and described in an embodie ment designed particularly for use in side lasting welt shoes.

The invention has for its principal object to provide an improved machine for-successively stretching and over-working sections of a shoe upper about the last and as said sections of upper are worked successively into lasted position securing them to the lip or rib of the insole by independent fastenings, for example, staples of fine wire driven through the upper and the channel lip or rib of the insole, the fastenings being so located so as'not to interfere with the succeeding operations on the shoe.

An important feature of this invention consists in improved mechanism by which a portion of the upper is first tensioned about the last and the shoe is then moved into position for the tensioned upper to be secured by a fastening.

A further feature of the invention is improved means for- Wiping the tensioned upper over the feather and against the channel lip or rib of the insole and for inserting a fastening to secure the overwiped upper in lasted condition.

A further feature of the invention resides in novel means cooperating with the fastening inserting means for positioning the upper in proper relation to the portion of the insole to which the upper is'to be secured.

Other objects and features of the invention including certain more important details of construction and combinations of parts will be disclosed in the following 'de' scription taken in connection with the acextending lever 6 link 24 to one arm pivoted at companying drawings and will then be particularl pointed out in the claims.

F igure 1 of the drawings is a side elevation of a machine having embodied therein the present invention in a preferred form;

F g. 2 is a plan view of the machine; and

Fig. 3.is a perspective detail of the staple forming mechanism.

The mach'ne in which the invention is herein shown as embodied is inits general features similar tothe machine shown in United States Letters Patent No. 1,059,984, granted April 29, 1913 on application of E. Erickson and lV. Cosgrove. As in. the machine of said Letters Patent the cams from which the staple forming, inserting and clenching mechanisms are operated are secured upon a main driving shaft 2 mounted in bearings in a head 3 of the machine, the head being supported by a base, not shown. A driving pulley loosely mounted upon the shaft 2 is arranged to be clutched to the shaft by a suitable clutch mechanism which is connected to a tion of the machine is effected.

In accordance with this invention afastening inserting machine organized as above indicated is provided with a gripper adapted to seize a marginal edge portion of the upper and tension it about the last. This gripper depends from the outer end of a forwardly which is pivoted on a rock shaft 8 having bearings in the machine frame, the inner end of the lever 6 being provided with a cam roll 9 which rides on a track on a cam 12 secured to the driving shaft 2 and operating through the described connections 'to lower the gripper to upper seizing position. The stationary jaw the depending gripper is pivoted on abolt 15 in the forked outer end of the lever and may be adjusted in and out by the adjusting bolt 16 mounted in a lug of the lever 6. The cooperating jaw nected by a link 23 to the stationary gripper and has its upper end connected through a '25 of a bell crank lever 26 on the lever arm 6, the other arm 27 of the lever being connected through ayielding connection 28 to an arm 30 of a bell crank '32 which, is pivoted on the rock shaft 8, the other arm33 of this foot treadle whereby opera- I 20 of the gripper is conbell crank a has one end secured to an arm on the casing by the expansive having a cam roll for engagement with a cam 36 secured to the main driving shaft.

The link 24 and the upper arm of jaw 20 I constitute a toggle b which firm gripping pressure is obtaine To insure a wide reach for the jaw 20 in closing and to flex the toggle the upper end of the movable jaw 20 is provided with a tail piece 37 whlclnis held by a spring, not shown, against a cam surface on the stationary jaw 18 and which 'throws the jaw jaw as the jaw frame of the machine and an adjustable thumb nut on the upper end of a rod 46 which extends through the casing and is pivoted at ,48 to the forward end of the lever 6 and operates to tension the spring 42 when the gripper is lowered by its cam 9.

Thegripper closing bell crank 32 is held against its cam 36 by a spring 4.- 9 which causes the jaws to release the upper at the end of the updraw movement, the formation of the cam 36 presented at that time permitting the spring so to act. The spring 49 43 and the other end connected to a projectin arm 50 on the bell crank 32.

-The Staple forming and staple driving mechanism of the machine, constructed substantially as described in said patent, is or- V ganized to drive a staple through the tensioned upper and .th of the insole and clench the staple on the inner side of the lip. This mechanism will be herein described only sufficient to make clear its relation to the new features ofv the machine. The outside former 52 of said mechanism isarranged to slide in a guideway in the head' of the machine from a cam groove in a cam 2 by alever arm andjs operated 53 on the shaft 55 fulcrumed in the machine head and having at its lower end a segment rack'which engages rack teeth formed on the rear end of the outside former. The outside former is constructed and arranged to embrace the inside former 57 as it moves forward and to form around the inside former a length of wire which has previously been fed into position by the wire feeding mechanism, not shown, and severed from the strand by thecutter 56, Fig.6. The inside former 5.7

is operated from a cam groove '11]. the cam 53 and is carried by a vertically sliding bolt mounted on the forward end of a lever 58 which is pivoted at 59 to the machine frame and has a cam roll 60 provided on its rear end, the cam roll 60 being re,- ceived in the cam groove in the cam 12. The staple when formed is driven through rough the channel lip receive the fastening,

a nose 62,,sometimes called a threat plate, by the staple driver 63, Fig. 3, secured to the forward end of a rack slide whichis reciprocated to insert the staple in the work by a lever 66 pivoted in the frame and having at its lower end a segmental rack 68 which engages the slide 65, the upper end of said lever being provi ed with a cam roll 69 which enters a cam groove in a cam 36 on the shaft 2.

' As hereinabove su'gg sted a feature of the invention is the provision ing-snot essive portions of upper over the feather and against the channel lip of the insole after the upper has been tensioned about the last. To ing means is rectiiprocated a sufficient distanceto cause its elivery end, which is provided with an upper wiper surface 67, to engage the upper before it is released by the gripper and wipe it over the feather and against the channel lip. The upper member-62 of the staple nose is arranged to slide in guideways in the machine frame and has tracted or inoperative position. In order to position the shoe properly with relation to the staple inserting means and also to cotiperate with the'staple inserting means in w ping the upper over the shoe bottom into position to vided. This guide comprises a member 72 adjustably secured by a set screw 73 to a ".orwardly extending portion of the frame and' having, two fingers 75 projecting on either side of the wiping nose in-the plane of operation thereof, .theforward end of the fingers 75 being flush with theend of the upper wiping and staple inserting means when said means is at the limit of its operative movement. i

In this machine, as in the machine of said Letters Patent above referred to, a clenching anvil is operated to move the shoe into position for the upper to be secured in lasted condition and to clamp together the parts of the shoe through which the staple is to be driven; 'In accordance with this invention the clenching anvil 76 slides in a guideway in a forward extension of the machine frame and has yielding connection with the outside former wherebythe'anvil is moved toward this end the staple formof means for wipa work guide is provil. This connection consists of a lever 77, the upper end of which is ivoted at 78 to the frame and the lower on of which has a pin and slot connection 7 9 with the rear end of the anvil bar 81. The lever 7 7 is connected througha yielding lost motion connection comprising links 80 and 82, to the slot ted upper end of a lever 84 which is pivoted at 83 to the frame and is connected at its lower end by a link 85, to the segment lever 55 which operates the outside former. A

. spring which is interposed between the links 80 and 82 is adjustable to vary the clamping pressure of the anvil.

The shoe is supported against the updraw of the gripper by a work support or sole rest 86 adjustably secured in the forward extension of the machine frame with its lower end in the plane of the fastening inserting means, the sole rest being preferably forked at its lower end so as to straddle the anvil 76.

In the use of the machine above described the shoe is presented to the sole rest 86 in position for the gripper 13, 20 to engage the shoe upper. Upon starting the machine the gripper is operated through the mechanism described, first, to reach down and to seize the marginal edge of the upper as indicated in dotted lines in Fig.1, and then to pull or tension the upper yieldingly about the last. After the gripper has reached its limit of updraw movement but before it has released the upper, the clenching anvil 7 6 is actuated to move the shoe into a position against the guide 7 2, the fingers 75, 75 of this guide engaging the upper and wiping it over the feather and against the lip or rib of the insole preliminarily to its being operated upon by the staple inserting means and also effecting an additional tensioning of the updrawn upper as shown in Fig. 1. The machine is preferably so timed that prior to the completion of this part of its cycle of operations the proper length of wire has been fed to the staple forming mechanism and formed into a staple in the manner describedin the above mentioned patent. As provided for by this invention, the outside former 52 is then further advanced so that its wiper surface 67 engages the upper and wipes into lasted position' that'portion of the upper. between the fingers 75, 75. This movement of the outside former also advances the upper member 62 of the staple nose into position thus providing a continuous driving passage to the upper standing against the lip or rib of the insole and insures the proper driving of the staple through the materials. The staple is then driven and the shoe moved to present another portion of upper to the machine so that by repeated operations of the machine successive portions of upper are lasted and fastened to the lip on rib of the insole; The machine is particularly useful for side lastgether the over-worked ing welt shoes the toes and heels of which are to be, or have been, lasted on other machines. The spring tension applied through the described gripper mechanism is appropriate for side lasting and the upper fastening staples inserted by this machine may remain permanently in the shoe and are located where they do not interfere with subsequent operations on a Welt shoe as do lasting tacks.
