To all who-m` t may concer/i: f

Be it known that I, ARTHUR Barns, asubject of the King of England, residing at Leicester, Leicestershire, England, have invented certain improvements in Upper- Shaping Machines, oliwhich the following' description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings'indieating like parts in the several figures.

This invention relates to machines for use in the manufacture of boots and shoes for shaping the upper-.materialsover a last or other shoe torni, and is herein illustrated in its application 'to a well-known type ot pulling-over machine, the machine herein shown including means for pulling over the upper and means for wiping the toe end portion oi the upper into lasted relation to a sole or insole,pherein frequently termed ttor convenience the sole. It is to be understood, however,y that in various novel aspects the inventionis not limited to a machine oil-the particular type illustrated nor to a machine including both pulling over means and lasting means. lt will also be recognized that in soine'oii its novel aspects the invention is not conlined, in respect to the shaping ot' the upper materials over a torni, to what is lgenerally understood as lasting in the restricted sense. l

In the shaping of the toe end portion of welt shoe upper materials in the character'- istic contour to lie inwardly over the feather of the sole and to contorni to the angle between the 'feather and the rib of the sole, particular difficulties are encountered in gathering and wiping the materials inwardly over the bottom ot the form in such manner as to avoid the presence oli ,vriiikles in portions ot. the upper which are visible in the linished shoe, due to the gatl'irying 'of the marginal portion ol. the upper within a contracted area inwardly from the ed 'e of the torni. The present invention pro vides, as an important feature, novel means for working thev margin oit the upper of welt or other type oix shoe inwardly overfthe bottoni o a torni under suchl control as to shape the upper'sinoothly and tree troni wrinkles along the edge oi the torni. For the purposes in view, the construction shown coinprises a. flexible loop wiper and means for operating it to gather the upper :materials about the toe and to wipe them inwardly over the bottom oiii the form, together with means ifor controlling the margin of the upper in such manner as to hold it smooth and free from wrinkles and to render Athe wiper el'liective to draw and wipe the upper inwardly with the required pressure. In the illustrative machine the control ofthe inargin ot the upper is effected by clamping means which permits the upper to slip in response to the pull of the flexible vwiper in order to equalize the tension under which theuppcr is shaped at the ditlerent points about the toe, a portion of the clamping means being also movable inwardly over the bottom oit the :torni to assist in the over-wiping operation and in maintaining the iiexible wiper close to the plane of the shoe bottom. y A further feature of the invention consists in a novel organization ot upper pulling means and means ttor working the margin of the upper inwardly about or over a liorm, the construction shown comprising marginal clamping means as hereinabove set forth which is operative by relative movement between Vitl and the form to pull the upper over the Yform under suclrcontrol as to permit the margin to slip inresponse to excessive tension in the upper pulling operation as well as in the subsequent overwiping operation of th liexible wiper. Included also in the organization herein shown are/*side grippers which in addition to pulling the upper over the top of the iorm have an overdrawiing movement to carry the margin inwardly over thebottoin of the torni in time relation to other operations ofthe niachine. An important teature is also to be recognized in a novel organization including means tor controlling the pressure on the lclamped margin of an upper in such manner as to reduce the pressure for the operation of working the upper inwardly about yor over the torni.k ln the construction shown, wherein the margin oi ythe upper is permitted to 1 p in response to excess ol tension in both the.l upper pulling operation and the overworkingv operation. the clamping means is so controlled es to relax the clamping pressure automatically after the upper pullingoperation'to permit the upper to slip more freely as itis wiped inwardly over the hottoin oi.' the Yform while still under effective control oi the clamping means reissue 8 slidek operated positively from a track cam on the cam shaft. Through these connections the clamping` member 25 is raised and lowered.. rlhe downward or upper clamping movement is rendered yielding by a spring llthat encircles the rod 241 between a shoulder on the upper end of the rod and a washer engaging the member 23 and is compressed to a substantial extent by the cam motion as the rod slides downwardly through the member 23. -`rlhis arrangement has two purposes. lt accommodates lvarying thicknesses of upper materials automatically and it provides for a partial relief ot the clamping pressure to allow the upper to be drawn out ot the clamp under tension.

lt will be understoodthat inthe use ol the machine a shoe is presented with its tread tace against the sole rest, the sides ot the upper being arranged within rthe jaws ci. the grippers and the toe of the upper spread over plate 16 in position.y to be clamped by the toot ot member Before the shoe is thus presented the plate 16 is moved 'forwardly by its treadle to make room 'tor the shoe, the treadle being then released to permit its spring to move the plate rearwardly as far as permitted bythe end 'faceot lthe last. When power is applied to the cam shaft-'the clamping member 25 is depressedto clamp the toe of the upper yieldingly under the compression of spring 4115, and the side grippers are closed and then updrawn, while at the same time the sole rest is rocked by its cani 4 to :torce the last downwardly and thereby to stretch the upper between. the last on the one hand and the grip `)ers and clamp on the other hand, and then the machine comes to rest. This organisation introduces the new 'feature in a machine ot the illustrated type that the toe oit' the upper is clamped on a continuous linel all the way around the toe and then the last is depressed into the upper and when the high peints o'l the toe ot the last produce excessive tension on the upper at certain places the clamp allows the upper `to slip to gire up stock at those places. The result is that the top ci the toe ot' the last is covered with upper stoel; that is under uniform strong tension at all points. he upper is not 'tcnsioned materially more over the high points which give the character to the style ot the toe than it is tensioned over the low places. 'This y produces a toe that stands up in its miginal brought into position to hold the shoe, and

the slide 124i is retracted to allow the springs 7X to press the side grippers inwardly. lt is during this stage of the machines operation that the toe lasting mechanism is operated.

For the toe lasting` operation it is important that the toe end of the last occupy approximately a predetermined altitude yin relation 'lo the plane ol' the clan'iping` plate 16 and, in order to adapt the mechanism to the varying` longitudinal curvature or inclinan tion ol the tread faces of dillerent lasts, this result is obtained by a toe presser which is a rod haring an adjustable loot and mounted lor movement in the bracket 15 to engao'e the tread 'face oit the toe and depress the iorepart oi the last. rlhe rod is connected at its upper end with the short rear arm oli the angle lever BO. The angle lever constitutes an equalizer. operating first Ato eilect clamping ot the upper and then to roclr slightly to ellect more or less depression ot the last `accordingl to the thickness ot the clamped stock so that they slice will be slightly lower if the stock is thiol; than it it is thin. rl` his ehiect is utilized in positioning the she@ properly in relation to the plate 16 foi.' the overwiping operation to be hereinafter described. f n

The normal angular position of the suspended angle lever 30 is determined bya spring` that extends from the lever 2S above the pivotal connection 29 backwardly to a stationary part ot the machine traine and by a detent 5G which is pivoted on the lerer and held by the spring against one end oit a bar 818X with which machines oit the illustrative type are provided :tor controlling the operation of the taclring' mechanism, When the machine is startedthe second time the bar @18X is retracted in unisonwith the bar 124; to allow the side grippers toswing inwardly and to canse the taclrers to follow inwardly, although only a part oit the whole distance through which they are eventually to be brought inwardly. ln this movement ol' 'the bars 12l and 818x theflcver is roclred about pivot 29, from the dotted line pmsition to the 'lull line position in Fig. 1 by the a ation of the spring lt will be noted that lever 2S and the rod Q-l, connected to the clamping foot 25 constitute a toggle that is nrumaily held substantially straight by the spring. detent.y and bar 81Sx but which Vflexed when the bar is retracttul. This lexure relieves the pressure ol the spring 5 and o'tfthe clamping toot 25 on the toe ot tue upper and lermits it to slip more readily for the lasting operation.

The automatic lasting means comprises a tleible wire lasting loop whichis a per inanent part el the machine and is adapted 'te be placed around' the toe oit the shoe immediately below the plate 1S after the shoe has been pulled and beliore the machine restarted r the second part oit its cycle.

aux

'lhe loop extends backwardly along each side of the machine over guide rolls 62, Figs. l and 3, and has its ends 'fastened to brackets 64 on a slide 222 which has a cani roll 65 and is reciprocated by a cam Q25 on the cam' shaft, this being the same cam and slide that close the side clamps. By this construction and organization the automatic lasting means 60 is operated to draw and wipe the upper into lasted relation to the innersole around the toe, the lasting means accommodating itseli amzomatieally to the shape ot the toe, and being guided in the proper wiping plane relatively to the shoe by the plate 16. The pull ot the lasting loop 60 on the upper causes the clamp to give up etocl under tension :for drawing over the last bottom, and the pull ot the loop also assists in advancing the clamping plate over the shoe bottom to the position shown in Fig. l, such advancing movement being further assisted by the treadle spring which is suiiicient of itself to effect more or less inward movement of the plate when the clamping pressure is relieved.

The machine comes to rest the second time with the parts in the position shown in l, the upper having` been worked into lasted position at the toe but not fastened. For fastening the upper the side tack carriers 10 are provided with binding cord holders, Figs. 4, 5, 6 and 7, comprising a slide 70 which has a bearing in the carrier l0 and is operated by two springs 72 to clamp and hold the cord a against the end ot the lower plate or wiper member Yi ot the tach carrier and in position under the driver holes 75 so that the tacks will pass through the cord when they are driven. The :tree end ot' the cord is held in a tapered recess formed in the edge of a rigid bar 76 and the other end is held in a similar recess in a second bar 77, the bars being connected with springs 78 to put tension on the cord. The operator applies the cord snugly by hooking one end in the bar 7G and drawing it through the adjacent holder and snugly around the toe under the lasting loop and then places it in the second holder and secures its other end in bar TT with the spring '76 under tension. liVhen the machine is restarted Alor the third and iinal part ot its cycle the `taclers complete their movement over the shoe and insert the tacks. The tacliers each have a component or rearward movement in advancing to tack inserting position and this tightens the cord just before it is tacked. Alfter the tacks are driven the machine is opened and the shoe freed with the upper pulled over and the toe lasted and bound in lasted relation to the innersole.
