MACHINE FOR W'ORKING HYPER??? OVER LAETS.

Application filed February 7, 192-3.

To all whom it may concern:

Be it known that I, Josnrrr GoULnnoUnN, a subject of the King of England, residing at Leicester, in the county of Leicester, England, have invented certain Improve ments in Machines for Vorking Uppers Over Lasts, 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.

lhis invention relates to machines for working or shaping uppers over lasts, and has more particular reference to operating means which is moved inwardly over the shoeagainst resistance of the shoe materials. An instance of such operating means is found in the wiper and tacker unit or units of a well-known type of pulling-over machine (the general characteris tics of which, as far as they concern the features of the present invention, are illustrated in United States Letters Patent No. 1,029,887, granted on June 11, 1912, and No. 1,135,954i, granted on April 13, 1915, upon applications of R. F. lttcFeely) and the invention is herein illustrated in its application to mechanism of that general type,

which it is one of the objects of the invention to improve in the different respects hereinafter set forth,- although it is to be recognized that in many of its aspects the invention is not limited to an organization of that particular type nor to machines including pulling-over means in their organ ization.

In the type of machine above mentioned each wiper and tacker unit is moved inwardly, to lay orwipe the margin of the upper over the sole and to position the unit for driving the upper fastening tack or tacks, by mechanism which is yieldable in response to resistance encountered by the unit and is intended to yield after the unit has arrived in proper relation to the shoe for the tacking operation. The provision for such yield enables the unit to accommodate itself to diiferent shapes or sizes of shoes,- and in the particular type of ma chine shown in said patent has for a fur Serial No. 617,608.

connections. Such an organization, however, imposes limitations upon the tightness with which the upper can be fastened on the last and upon the certainty in respect to the position of the upper fastening tacks. These limitations arise from the fact thatunless the wipers are advanced well over the edge of the shoe bottom, or at least are pressed hard against the upper before the latter is released by the pulling-over grippers, the tension of the upper is likely to be relaxed more or less before the upper is fastened, and from the further factthat if the wiper mechanism is constructed or adjusted to apply sufiicient pressure to afford an adequate margin of safety in this respect, there is danger that in operating on some shoes the resistance encountered by the wipers will be so great as to cause the operating connections to yield prematurely and thus prevent the tacking means from being moved far enough inwardly over the bottom of the shoe prior to the tack driving operation, so that the tacks will not be driven at such distance from the edge of the shoe bottom as to hold the upper properly.

lVith the object, among others, of avoiding the above mentioned difficulties, the present invention provides, as one important feature, a novel construction and arrangement of means for controlling a device for operating on a shoe (herein shown as a wiper and tacker unit), the construction shown comprising novel means for moving the unit inwardly over the bottom of the shoe through positively acting connections and for limiting the positive movement of the unit as determined by the particular shoe operated upon. In the construction herein illustrated such control is etl' cted by the provision of a cam member which is set or positioned by connections to a clamp on gaging the side of the shoe and which acts automatically at a time thus determined to release an element of the positive means provided for moving the wiper and tacker unit inwardly, thus rendering said element yield able only after the wiper and tacker unit has been moved substantially into proper position for driving the tacks, to accommodate the operating means to different shapes,

and sizes of shoes without damage to the machine or to the shoe and, as applied to the particular type of machine illustrated,

to cause the tacks/to be driven in response to such yield in the operating connections.

Further features of the invention are to be recognized in novel means for moving a wiper positively inward over a shoe to a position determinedby the shoe, and in novel means for mounting a wiper. to'permitit to yield universally in directions transverse to its overwiping plane, an'd'it may be, as herein shown, to prevent it from yielding in said plane. I

The above and other featuresof the invention, including certain details of construction and combinations of pars, will now be more particularly described by reference to the accompanying drawings and point-ed out inthe claims.

Inthe drawings,

Fig. 1 is a view substantially in front elevation of one of the side wiper and tucker units ota machine or the general type illustrated in said prior McFeely patents, together with a portion of the upper pulling and shoe clamping means, with controlling mechanism constructed inaccordance with the present invention applied thereto;

Fig. 2 is aside elevation of apart of the mechanism shown in Fig. v1;

Fig. 3 is a view partly in plan and partly in section, on an enlarged scale, showing a portion of the means for imparting inward movement to the side wiper and taclrer unit,

including a portion ofthe controlling mcrhanism ot' the present invention;

Fig. 4i is a plan view, on an enlarged scale, of a portion of the shoe clamping means shown in Fig. l, and v Fig. 5 is a section on the line 55'ot' Fig.

It will be understood that in the type of machine illustrated the upper is pulled by oppo ite side grippers, oneof which is shown 2, as well as by a toe gripper, the shoe being held by a sole rest t against the pull applied to the upper. lVhile the upper is held by the grippers side clamps are moved inwardly into supporting and holding engagement with the shoe at its opposite sides, these clamps"comprising arms (3, one only of which is shown in the drawings, which carry relatively movable clamp members 8 and 10 for engaging the shoe in different loca tions. The member 8 ismounted on a block 12 swiveled in the end of a clamp support or slide l l so that the clamp member may adjust itself to the shoe about an axis e2;- teuding: heightwise of the'shoe. The slide 1% is movable laterally of the shoe in the arm 6 and is connected by rack and'pinion mechanism to another" slide. which carries thetrneinber 10, as described more fully in Patent No. 1,135,954. 7

After the clamps have engaged the opposite sides of the shoe the margin oi? the 'up'peris wiped inwardly over the sole and is fastened, at least at the sices of the forepart. by driving a plurality of tack spaced along the margin of the sole. For overwiping and tacking the upper at each side of the forepart a wiper and tacker unit is provided comprising a supporting arm 16 which is swung inwardly toward the shoe andcarries one or more wiper plates or wipers 18 for engaging the margin of the upper, a pair of such wiper plates being usually provided at each side of the shoe. After the wipers have been moved inwardly far enough to press and hold the upper on the edge of the sole, the arm 16 engages a latch 20 on the gripper to release the gripper from the upper. The wiper plates 18 are carried by a blocl: 22 which also carries the tack holders and which is swiveled on the arm 16 to turn, together with tack drivers 2-Jlabout an axis extending lengthwise of the arm, as described in the prior patents. The tact: drivers 2i, which are equal in number to the number oi tacks which are to be driven at the side of the shoe, are operated by a spring-impelled driver bar 26 (Fig. 3). The bloelr22 has fixed thereon an abutment plate 28, and as the arm It; continues its inward movement after releasing the gripper from the upper this plate is carried into engagement with :1 stop or abutment shouldcr'BO formed on the swivelled clamp block 12. This serves to limit the inward movement ol the arm.v and also causes the block 22 with its wiper and tachcr mechanism to turn about its axis on the arm. 16 into the position determined the. shoulder 30 on the swivelled block for locating the wipers andthe taclrrs in the proper angular relation to the edge of the shoe bottom.

The mechanism for in'lpalrting inward movements to the arms 16 is in many respects similar to the mechanism shown and described in Patent Yo. 1,029,387, and comprises (Fig. a slide 32 connected to the arm and operated by another slide 3% to which movement is imparted through a gear segment 36. The slide 34: carries a plunger 38 which is n'iounted: in a plunger hous 40 in the: slide and is controlled by a spring; 42, the latter bearing at'its outer end on a member a l. which is threaded in the outer end. of'the housing. The plunger It; and the slide Eli. are provided with cooperating wedge faces whereby, upon yield oi. the plung r, the slide S-l is permitted to r relatively to tl idc $52 in response to Ix ance encountered'by rne latter when the arm 16 arrives at its limit of inward movement determined by engagemcnto'f the men'dzer 28 with the shoulder 30. The slide 3% has a part for controlling the driver bar 28,
