24 Claims.

This invention relates to apparatus for use in applying pressure to shoe bottoms and is illustrated herein with particular reference to its utility in cement attaching soles to shoes.

In cement attaching soles to shoe bottoms it is desirable to have the work engaging surface of the pressure applying member, usually a yieldable pad, conform as closely as possible to the longitudinal contour of the shoe bottom before pressure is applied since this facilitates locating the sole and shoe in the proper position on the pad and also makes it unnecessary to deform or distort the pad an unreasonable amount to insure that substantially the same pressure will be applied to all portions of the shoe bottom. It is also desirable after obtaining an initial conformation of the pad to the contour of the shoe bottom to have it capable ofbeing even more closely conformed to such contour under pressure 20 from the shoe.

An object of the present invention is to provide an improved apparatus involving a novel organization of parts for accomplishing the above results.

To this end and in accordance with one feature ofv the invention, there is provided, in apparatus having a pad for applying pressure to shoe bottom, separate members for holding and supporting the pad, means for maintaining the pad holding members in operative position while permitting movement thereof in the longitudinal median plane of a shoe on the pad, and a fulcrum for each of said members, said fulcrums being adjustable lengthwise of the pad to vary the positions of the axes about which said members move in said plane. the pad supporting or holding members may. rock or swing about the fulcrums provided by abutments and the pad holding members are so mounted that adjustment of the fulcrums or abutments lengthwise of the pad permits swinging movement of the pad holding members into any desired angular position. The adjustment of the fulcrums lengthwise of the pad is accomplished in the present illustrative embodiment of the invention simultaneously by a single screw having right and left threads acting respectively on each of the abutments providing the fulcrums, so that when the screw is rotated the abutments will be moved simultaneously toward or away from each other lengthwise of the pad to shift the fulcrums and thereby permit the pad holding members to be rocked into different angular positions. This rocking or swinging arrangement of the pad holding mem- As herein illustrated,

bers about the abutments upon which they are supported also permits these members to be further positioned at the proper angles by pressure of the sole and shoe against the pad. By this arrangement the pad may not only be initially conformed to the'longitudinal contour of the shoe bottom but, if desired, the amounts of pressure applied to different portions of the sole and shoe may be controlled and varied at will. As herein illustrated, the mechanism permitting rocking movement of the pad holding and supporting members about the abutments is provided with friction means for initially maintaining these members in any angular position into which they may be moved.

In accordance with another feature of the invention, there is provided improved means for causing the pad to be positioned automatically in accordance with the transverse angle of the portion of the shoe bottom engaging the pad. As herein illustrated, the pad of the present apparatus is caused to conform to the transverse angle of the forepart of the shoe bottom under pressure of the shoe by an insert located between the pad and its holding or supporting member, this insert having a bottom surface which is convex transversely of the pad. When pressure is applied to the sole and shoe, the forward portion of the pad will be tipped transversely of the apparatus by rocking movement of the insert until said portion is located at the same transverse angle as the plane of the forepart of the shoe bottom. I

With the above and other objects and features in View, the invention will now be described with reference to the accompanying drawings and will thereafter be pointed out in the claims.

In the drawings,

Fig. 2 is a perspective View, partly in section,

of an end portion of the pressure applying apparatus including the pad;

Fig. 3 is an enlarged perspective view of a portion of adjusting means on the apparatus;

Fig. 4 is a plan View of the apparatus with the central portions broken away;

Fig. 5 is a sectional view taken on the longi- I tudinal median line of the pressure applying apparatus with a sole and shoe under pressure therein;

Fig. 6 is a transverse sectional View taken on the line VI VI of Fig. 5; and

chine of that type but may be'used with equal advantages on other types of machines for applying pressure to shoe bottoms such, for example, as a sole laying machine.

The apparatus comprises a base plate l0, herei in illustrated as secured by screws M to a table or bracket i2 forming a portion of a rotary turret on the cement sole-attaching machine. At its right-hand end, as viewed in Fig. 1, the plate i0 is provided with upstanding lugs 16 to each of which is pivotally secured by a shoulder screw l8 a relatively long link 2%! which extends lengthwise of the plate W for substantially its full length. The links 26 are pivotally secured at their opposite ends by screws 2a to a pair of lugs '22 extending downwardly from. a flat rectangular member 26 forming a part of mechanism for. holding and supporting the pad of the pressure applying apparatus. Above the links 2! on the lugs 22 are pivotally secured by a transverse shaft 28 (Figs. 1 and 4) another pair of relatively long links 30 which extend lengthwise of the base i0 toward its right-: hand end and are pivotally connected by another transverse shaft 32 to downwardly projecting lugs 36 formed on the lower side of another flat member 36 of substantially the same shape as the member 26. As stated above, the

members

26 and 36 hold and support the pad with which the apparatus is provided against pressure of a sole and shoe during the cement attaching or sole laying operation, and these members are provided with means for holding the pad thereon and-with further means for causing the work engaging surface of the pad to be conformed substantially to the shape of the shoe bottom.

The pad conforming means, as herein illustrated, comprises an insert 33 resting on the pad holding member 26 at the forward portion of the apparatus, this insert having a lower surface '30 which is convex transversely or widthwise of the apparatus, as shown in Fig. 6. The insert 38 may be formed of one or two sections (herein shown as two), and it has a concave upper surface 32 which may be substantially complemental to the desired shape of the tread surface of the forepart of a finished shoe or, if desired, may be more concave than is required for a shoe bottom so that pressure of the apparatus against the sole and shoe will be greater at their marginal portions than at their central portions. The.

convex surface 40 of the insert 38 permits the right-hand end of this member has a projection 54 thereon to prevent the insert from sliding rearwardly of the apparatus off the pad holding member during the operation thereof.

On opposite sides ofthe forward end of 'the insert 38 are mounted a pair of upstanding straps 46 arranged for heightwise adjustment by screwand-slot constructions G8 and having inwardly projecting portions which overlie the marginal portions of a pressure applying pad 56 and secure the left-hand end of the pad, as viewed in Figs. 1 and 2, to the insert 38. The pad 5!], as

' herein illustrated, comprises a relatively thick layerof resilient material such as rubber which may be conformed under pressure to the shape of the upper surface 42 of the insert and may also end. Both the insert 52 and the right-hand end of the pad 5! are secured against the member 36 by upwardly extending straps as which are adjustably secured to opposite sides of that member byslot-and-screw constructions 58. The straps 56, as shown in Fig. 4, have inwardly projecting portions which overlie the pad and secure it and the insert 52 against movement on the member 36.- 52 is flat but it has an upper surface 86 which is substantially complemental to the shank and heel portions ofa shoe bottom except that it is provided at opposite sides of its forward portion with substantial bulges 62 (Figs. 1 and '7) arranged to force the opposite sides of the pad firmly against the shoe upper at the shank portion of the .shoe and thereby to produce closefitting sole margins at said shank portion.

'In order that the pad holding and supporting

members

26 and 36, and the inserts and pad carried thereby, may be supported against pressure from a sole and shoe and may still be angularly adjustable relatively to each other around their respective pairs of links 20 and 3B, the

members

26, 36 are supported respectively near their adjacent ends by

abutment members

64 and 66 adjustably mounted on the base plate l0 and extending transversely across the full width thereof, these abutments providing fulcrums about which the

members

26 and 36 can rock. At their upper portions the

abutments

64 and 66 are cut away intermediate of their opposite sides to provide three upstanding ears 68 (Figs. 1 and 4), and the abutment 64 carries in these cars a'transverse pin 19 held against rotation in the abutment by a set screw .12. The abutment 66 has mounted in its ears 68 a transverse pin 14 secured to the central car by another set screw 12. Rotatably mounted on each of the transverse pins lll, M between the ears 68 is a. plurality of rollslfi .which engage the bottom surfaces of the

pad holding members

26 and 36 and, with the pivotal arrangements provided by the links 2!] and 30, support the

members

26 and 36 for swinging movement about their fulcrums lengthwise of the plate H] and the pad 5|] in the longitudinal median plane of a shoe mounted on the pad.- Since the abutments' 54, B6 are adjustable lengthwise relatively to the base plate I!) and the pad 59, the fulcrums of the

members

26, 36 may be varied to permit rocking movement of these members lengthwise of the pad to locate said members in different angular positions relatively 'to each other.

' The

abutments

64 and 66 are adjusted lengthwise of the pad by a screw l8 threadedthrough the abutments and supported thereby, this screw being provided with right-hand threads on it's'forward'portion which act upon the'abutment The lower surface of the insert 64, and with left-hand threads 82 upon its rear portion which act upon'the abutment 66 so that, whenthe screw is rotated, the fulcrums about which the pad holding members swing will be moved simultaneously toward or away from each other at equal speeds thereby changing the locations of the fulcrums and permitting the angular positions of the pad holding members and the pad supported thereby to be changed in accordance with the longitudinal contour of the bottom of the shoe resting on the pad 50 or, if desired, in accordance with the pressure which is to be applied to different portions of the shoe bottom.

The forward or left-hand end of the screw 36, as viewed in Figs. 1 and'5, has threaded thereon a spool-shaped collar 64 the reduced central portion of which rests in avertical slot 86 in an angle plate 88 (Figs. 3 and 5) secured to the base plate in, so that the collar 84 is confined against movement lengthwise of the pad but may be rotated relatively to the plate 88. On the extreme left hand end of the shaft 16 is a lock nut 99 which, when it is turned against the collar B4, locks it to the shaft 18 so that manual rotation of the lock nut thereafter rotates the shaft and causes the abutments or

fulcrums

64, 66 to be adjusted toward or away from each other lengthwise of the pad in the manner described. When, however, the lock nut 96 is loosened from the collar 84 the latter may be rotated in the member 86 independently of the lock nut and shaft 18 to cause the shaft to move bodily lengthwise of the pad without rotating and there by to adjust the

abutments

64 and 66 as a unit in the same direction, that is, either forwardly or rearwardly lengthwise of the pad.

It will be seen from the above that the adjustments provided by the spool-shaped collar 84 and the lock nut 96 permit the

abutments

64 and 66, which serve as fulcrums about which the

pad holding members

26 and 36 swing or rock lengthwise of the pad, to be adjusted simultaneously lengthwise of the pad either in the same direction or in opposite directions. Consequently, it is possible with this construction to locate the abutments and the rolls 16 in any desired position lengthwise of the pad relatively to the

members

26 and 36. As illustrated in Fig. 5, the abutment 6G is located a little forwardly of the ball line of the shoe mounted on the pad whereas the abutment 66 is located substantially midway between the ball line and the heel end of the shoe. The arrangement shown causes sub- 1 stantially uniform pressure for each unit of the bottom area to be applied to the shank and heel portions of the shoe and a pressure to the forepart which gradually diminishes from the vicinity of the ball line to the toe end of the shoe. It will be clear, therefore, that the pressures at both the forepart and the rear portions of the shoe bottom could be varied in other ways if desired by longitudinal adjustment of the

fulcrums

64 and 66.

After the fulcrums have been adjusted lengthwise into positions which permit the

members

26 and 36 and the pad supported thereby to be located so that the sole engaging surface of the pad conforms approximately to the longitudinal contour of the shoe bottom, it is desirable to maintain the pad holding and supporting members in their positions of angular adjustment until the shoe and sole on the pad are actually under pressure. For this purpose the shaft 28 (Fig. 4) extends beyond the link 30 at the inner side of the pad and carries a; compression spring 92 which is forced against the link.36 by a nut 94. At the right-hand endof the pad, the shaft 32 also extends inwardly beyond the pad and carries a compression spring 96 which is forced against the link 30 by a nut 98. The springs 92 and 66 may be put under suiiicient compression by their retaining nuts to cause the

members

26 and 36 to be maintained by friction alone in whatever angular positions they may have been swung after adjustment of the

abutments

64 and 66. When pressure is applied to the sole and shoe, however, the

members

26 and 36 and the pad 50 canfurther rock about their fulcrums on the abutments into angles which coincide with those of the corresponding portions of the shoe bottom.

Although the operation of the apparatus will be apparent from the foregoing description, its usein connection with a cement sole attaching machine of the type referred to above will be reviewed for the purpose of clearness. As shown in Fig. 1, the cement sole attaching machine is provided with pressure applying members I60 and I62 for engaging respectively the forepart of a shoe A (Fig. 5), and the rear portion of a last L in the shoe. The shoe A may first be treated on its bottom surface with a suitable cement such, for example, as pyroxylin or chloroprene and it may then be mounted on the pad 50 with a sole B, the marginal portion of the upper surface of the sole having been similarly treated with cement. When the cement is in condition to cause adhesion of the parts, the operator positions the

members

26 and 36, by adjustment of the abutments orfulcrums 64 and 66 through rotation of the lock nut 9|], in angular positions which conform the upper surface of the pad as closely as possible to the shape of the longitudinal contour of the bottom of the shoe which is resting on the sole. If the shoe is a particularly large shoe or a particularly small shoeithe operator may loosen the lock nut 9|] and rotate the collar 84 to move both abutments as a unitlengthwise of the pad until they are located substantially equal distances from the opposite ends of the pad, thereby locating the abutments in similar positions relatively to their respective

pad holding members

26 and 36. The operator may them screw the lock nut 90 against the collar B4 and by further rotation of the lock nut in one direction or the other rotate the screw 80 to move the abutments simultaneously towardor away from each other until each abutment is located in such a position lengthwise of the shoe that it will cause the pad holding member and pad to apply the desired pressure to different portions of the forepart andthe rear portion of the shoe bottom. After the adjustments have been made, the

members

26 and 36 may be caused to swing or rock about their fulcrums to conform the pad as closely as desired to the longitudinal contour of the shoe bottom, this rocking movement being permitted by the link arrangement which supports the opposite ends of the pad holding members, and these members being maintained by friction in their angular positions by the compression springs 92 and 96.

The pressure applying members I00, I02 of the cement sole attaching machine may now be caused to move downwardly into engagement with the last and shoe through the actuation of fluid pressure operated mechanism with which the machine is provided'for pressing a sole and shoe against the pad to perform a cement sole. attaching or,

if desired, a sole laying operation. As shown in Fig. 6, the inner surface 42 of the insert 38 is of such a shape that the forepart of the shoe bottom will be pressed by the pad into the desired contour both lengthwise and widthwise of the shoe. Moreover, if the transverse angle of the plane of the forepart of the shoe is different from the transverse angle of the plane of the rear portion of the shoe, the insert 38 will rock transversely of the pad until the latter conforms itself accurately to the transverse angle of said forepart. shank portion of the pad will cause the sides of the pad to press firmly against the shoe upper adjacent to the shank portion of the sole, thereby producing a close'fitting sole margin at the shank portion of the shoe. As indicated above, as the pressure applied by the cement sole attaching machine increases, the

pad holding members

26 and 36 may be further adjusted about the

abutments

64, 66 into accurate conformity with the angles of the forepart and the shank and heel portions of the shoe bottom.
