ROUGH ROUNDING MACHINE Filed Aug. 26, 1953 2 Sheets-Sheet 2 J Inventor Anhonse CKu/ik By his At figiney United States Patent 2,697,238 ROUGH ROUNDING MACHINE Alphonse C. Kulik, Ipswich, Mass, assignor to United Shoe Machinery Corporation, Flemingtou, N. J., a corporation of New Jersey Application August 26, 1953, Serial No. 376,619 13 Claims. (Cl. 12--85) This invention relates to rough rounding machines and is illustrated herein as embodied in a machine of the type disclosed in United States Letters Patent No. 2,543,760, granted on March 6, 1951, upon an application of I. C. Cantley.

The above-mentioned Cantley machine has a single guide which is adequate for determining the sole extension in certain classes of work, either because the shoe construction makes the use of a second guide unnecessary, or because of simple requirements as to the sole edge extension. However, in some cases the shape of the shoe does not permit the use of only one guide; and in others it may be desired, for reasons of style, to position the shoe when the forepart is rounded differently from the manner in which it is positioned when its shank portions are rounded.

An instance of the use of both a crease guide and fore-part gage for positioning the shoe, while its shank and forepart portions, respectively, are rounded, occurs in a well-known rounding machine of the type disclosed in United States Letters Patent No. 1,030,606. granted on June 25, 1912, upon an application of F. H. Perry. In this machine, the forepart gage, which normally is in its inoperative position, is moved into its operative position by lowering a treadle. Simultaneously with any such movement of the forepart gage, the crease guide, which is normally in its operative position, is moved away therefrom. This interchange of the guide and gage is made whenever the rounding out passes out of the shank into the forepart and an opposite interchange, by which the gage and guide are returned to their original positions, is made whenever the rounding cut passes out of the forepart into the shank.

It may be desired, according to different requirements of shoemaking, that when an interchange of the guide and gage takes place, the shoe be held at the same height relatively to the tool or that the shoe be either raised or lowered, depending upon whether the sole edge extension is to be the same or different in the forepart and shank. In order that this interchange of guide and gage, in the operation of the Perry machine, may be made gradually when the sole edge extension is different in the shank and forepart, the machine is provided with a so-called grading device which utilizes the movement of the forepart gage into and out of its operative position to control the movement of the crease guide out of and into its operative position, respectively. As any movement of the forepart gage toward its operative position is accompanied by a corresponding, although smaller, movement of the crease guide away from its operative position, the shoe may be subject to an undesired premature movement relatively to the knife, under the control of the crease guide, before the control of the shoe is taken over by the forepart gage. With such operation of the guide and gage the transitional cut tends to be too long if the interchange of the gage and guide is made slowly enough to make the transitional cut gradually; and whether the transitional cut is made gradually or as abruptly as is usually desired, retractive movement of the crease guide prior to the arrival of the forepart gage into its operative position, re sults in an undesired hollow in the sole edge.

This difficulty has been partly overcome by the provision of means, as disclosed in United States Letters Patent No. 1,331,789, granted February 24, 1920, upon an application of L. G. Smith, which cooperates with the above-mentioned grading device, for delaying the movement of the crease guide out of its operative position until the forepart gage will have arrived in its operative position. However, the crease guide of this construction is operated so abruptly,

provided in the illustrative macrease guide and forepart gage,

the combination with separate and distinct operating mechanisms for the guide and gage each of which mechanisms has a predetermined but adjustable range of movement, of operator controlled means common to both mechanisms for driving them selectively, each' mechanism being operated throughout its range of movement, or substantially so, before the other is operated} Thus, during the first interchange of the guide and gage the forepart gage is moved into engagement with the shoe before any appreciable retractive movement of the crease guide takes place; and conversely, during the second interchange, the crease guide is moved into its operative position before the forepart gage is retracted enough to permit the shoe to rise above its position to be determined by the crease guide.

Invention is also to be recognized in provisions for separately adjusting both guide with respect to their operating mechanisms. Hence, When either operating mechanism is moved to one end of its predetermined range of movement, the guide or gage will also have been moved to a predetermined operative position depending upon its adjustment relatively to its operating mechanism, and it is evident that the adjustment of either the guide or gage has no effect upon the other.

In accordance with a further feature of the invention, the above-mentioned selective operation of the operating mechanisms for the guide and gage is obtained by the ber of the treadle operated means and the operating mechanisms, one set of these connections being provided yieldingly to act upon the forepart gage operatforepart gage into its tween the driving member and this operating mechanism.

According to a further feature of the invention, pro-' vision has been made for adjusting each of the abovementioned operation of either of the operating mechanisms can be varied without affecting that of the other. For the same reason, any desired variation in the interchange of the guide and gage can be obtained and without affecting heir operative positions. These and other features of the invention will now be described in greater detail with reference to the accompanying drawings, and will be defined in the claims.

particularly upon belng returned to 1ts operative position, as to defeat, to

the forepart gage and crease' but during further move-'- sets of connections so that the timing of theplan view of the structure illustrated in machine as viewed' A shoe S to be operated upon in the illustrated machine is presented thereto with. its. bottom seated upon a reciprocatory bottom rest 12 and the sole edge is rounded by a chopping knife 14 which cuts through the sole against an oscillating feed point 18. The feed point and bottom rest. are moved from side to side. in synchronism to impart intermittent feeding movements to the work extending from right to left, the feed point having a dwell between its feed and return strokes during which the knife makes its cut through the stationary work against the feed point. The above-mentioned parts, their mounting and their driving mechanism, are the same in the present machine as in that disclosed in the abovementioned Cantley patent, to which reference may be made for a complete disclosure of this structure.

The shoe is positioned relatively to the knife, to control the sole edge extension, either by a crease guide which is received in the welt crease of the shank portion of the shoe in the usual manner, or by a forepart gage 22 which engages the margin of the upper adjacent to the welt crease around the forepart. The crease guide and forepart gage, although they are the same individually as the corresponding parts in the well-known type of rough rounding machine disclosed in the abovernentioned Perry patent, are mounted and operated, in accordance with the present invention, so as to permit greater flexibility in their adjustment and control of their interchange when the rounding cut crosses the junctions of the shank and forepart.

With the machine at rest, the crease guide 20 is supported in its normal operative position upon a U-shaped slide 24 (Figs. 1 and 3) which is mounted to move freely vertically in a channel formed in a housing 26 for the operating mechanism of the machine. A cover 28 fixed'to the forward end of the housing holds the slide in the above-mentioned channel. The crease guide is adjusted vertically, to change its operative position relatively to the knife, by turning a screw 30 which is threaded into the slide 24 and is mounted to rotate freely,

without moving axially thereof, within a trunnion block 32. This trunnion block is pivotally mounted upon a pair of trunnions 34 which are threaded in the forward ends of a bifurcated lower arm of a bell crank 36 which is mounted to swing freely upon a cross shaft 38, the

latter being fixed upon a bracket 40 secured to the top of the housing 26. The bell crank is operated by toggle links 42, 44, which have a common pivotal connection at 46, the former link being fixed to a shaft 48, and the latter being pivoted at 49 to an upwardly extending arm of the bell crank 36. A portion of the shaft 48 extending outwardly to the left from the bracket 40 carries a lever 50 and an arm 52, the latter being fixed to the shaft by means of a key 54 (Fig. 4) and the former being freely rotatable upon the shaft. A spring-biased detent 56 (Fig. 2) carried by the arm 52 may be retracted entirely within the arm by pulling upon its knob to permit a change in the angular relation of the arm 52 and the lever 50, for a purpose to be described later, the detent being arranged to enter either of two holes 60, 62 (Fig; 4) formed in the rear end of the lever 50.

The above described operating mechanism for the crease guide has an adjustable range of movement both extremes of which can be varied by adjusting setscrews 64, 66 which are threaded into a forwardly extending arm of the lever 50 and are arranged to abut a stop 68 fixed upon the bracket 40. The setscrew 66 is normally held in engagement with the stop owing to the provision of a spring 70 (Fig. 3) which is compressed between a lug 72 fixed to the bracket 40 and a shoulder on a rod 74 which is mounted to slide axially in the lug. The rod is pivoted at 76 to an arm 78 fixed to the abovementioned toggle link 42. Accordingly, the spring 70 tends to swing the toggle links 42. '44 upwardly, such movement of the links being limited. by the enga ement of the setscrew 66 with the stop 68. Thus, although the setscrew 66 has the effect of controlling the operative position of the crease guide 20 throu h the mechanism above described, its function, together with that of the setscrew 64, is primarily to limit the range'of movement of the operating mechanism for the crease guide. The screw 30 is ordinarily employed to adjust the operative position of the crease guide for any desired range of movement of its operating mechanism, as limited by the screws 64, 66.

The mounting of and the operating mechanism for the forepart gage 22 will now be described. The forepart gage is pivotally mounted at 80 (Figs. 1 and 3.) upon a slide 82 which is mounted to move freely heightwise within a swivel block 84 having a recess at each side thereof in which are seated trunnions 86, 86 threaded in lugs protruding forwardly from the cover 28.

spring-biased detent 88 acts upon the upper end of the forepart gage to hold its lower portion in engagement with the forward surface of the crease guide 20. Into the upper portion of the slide 82 is threaded a screw 90 which is mounted to rotate freely, but without movement axially thereof, in a swivel block 92. This block is carried by a pair of trunnions 94, 94 threaded in the forward bifurcated end of an arm 96 which is pivoted upon the bracket 40 at 98 and has an extension 100 rising upwardly therefrom. A toggle link 102 is pivoted at 104 to the extension 100 and is also pivoted at 106 to another toggle link 108 which is fixed to a shaft 110 rotatably mounted in the bracket 40. Upon the lefthand end of this shaft there is fixed an arm 112 the forward end of which carries a, swivel block 114 which is bored freely to receive an upwardly spring-biased treadle rod 116, the upward movement of which is limited, in the position illustrated (Fig. 4), by a stop (not shown).

1 The upper position of the arm 112, and hence the collapsed position of the toggle. 102, 108, may be varied by adjusting check nuts 118 threaded on the treadle rod beneath the swivel block, the latter being yieldingly held by a spring 120, against the upper check nut 118. The upper end of the spring is supported by a pair of check nuts 122 which may be adjusted along the treadle rod to vary the compression in the spring.

It will now be evident that by lowering the treadle rod 116 the normally collapsed toggle. links 102, 108 will be moved into their extended relation which is determined by the engagement of a projection 124 on the link 108 with the top of the link 102. With the toggle links in this relation the forepart, gage is in its operative position which may be readily varied, independently of the crease guide, by adjusting the screw 90.

As stated above, the toggle links 42, 44 in the operating mechanism for the crease guide 20 are normally in their extended relation and the crease guide is normally in its operative position. The forepart gage is normally in its inoperative position because the toggle links 102, 108 in the operating mechanism for the forepart gage are normally in their collapsed relation. However, when the treadle rod 116 is lowered to bring the forepart gage into its operative position the lower one of a pair of check nuts 126 (Fig. 4), threaded on the treadle rod, engages a swivel block 128 which is carried by a link 130, the latter being pivoted upon the forward end of the lever 50. Further downward movement of the treadle rod, permitted by the yielding action of the spring 120, swings the lever 50 of the operating mechanism for the crease guide so as to move the crease guidefrom its operative position into its inoperative position. In order to provide a freely sliding connection between the treadle rod and the swivel block 128, a tube 131 encases the rod and is arranged to pass freely through the swivel block 128, and a pair of check nuts 132, threaded upon the treadle rod, hold the tube firmly against thelower checks nut 126. It will be understood that the check nuts 126 may be adjusted along the treadle rod to provide any desired amount of lost motion of the treadle rod with respect to the swivel block 128 before the latter is engaged bythe lower check nut 126 and the movement of the crease guide out of its operative position is begun. Similarly, for any given adjustment of the check nuts 126, which control when, during the lowering of the treadle rod, the operation of the crease guide operating mechanism is begun, any desired adiustment of the check nuts 118 can be made to control the arrival of the forepart gage into its operative position with respect to the operation of the crease guide. Thus,

any desired change in the timing of the interchange of the gage and guide may be made without affecting their operative positions.

The use and operation of the illustrative machine will now be described, assuming first that the rough rounding operation will be performed upon a shoe which is to have the same sole edge extension around the forepart as in the shank. The rounding operation is begun, on a right shoe for example, at the inside shank, the

'- out being started at the heel end of the sole, continued shoe is ordinarily viewed, exposed.

To effect this change in the operator depresses the ering the treadle rod guiding of the shoe, the treadle (not shown) thereby low- 116. By so doing, the forepart the chopping knife.

of the forepart gage into its operative position must be this end, just referred to above, the nuts 126 on the treadle rod 116 will have been adjusted the toggle 42, 44 against the pressure of the spring 70 and to move the crease guide away from the shoe upper. With the treadle rod now held in its lowermost position, as determined by the setscrew 64 bearing against the stop 68, the rounding out is carried around the forepart under the control of the forepart gage to the junction of the forepart with the outside shank near the outside ball line.

At this point, where the sole edge above) begins to converge toward the the operator releases the treadle permitting the treadle operative position without affecting the forepart gage because lost motion permitted by the ex ansion of the spring 120 now occurs between the swivel block 114 until the upper check nut 118 engages the lower side of the swivel block ment of the setscrew 66 with the Under another shoemaking requirement calling for a relatively narrow sole edge extension around the forepart, that is, an extension considerably narrower than that produced by the above machine, it is necessary to perrnlt the shoe to rise relashank Dortion of the shoe. This result can be elfected by readiusting the screw 90 so as to raise the forepart gage above its former position.

With the machine in this state of adjustment, the treadle is depressed as the rounding out emerges into the forepart and the forepart gage is brought nearly 6 to its'operativeposition without engaging the shoe. At this time, the 'lower one of the check nuts 126 engages the swivel block '128 and the retraction of the crease guide begins. Further lowering of the treadle now causes the forepart gage to be moved to its operative position and further retraction of the crease guide with which until'it engages the forepart gage which the cut made interchange between them results in the quickest possible interchange.

interchange of the crease gulde and forepart gage for any setting thereof may be secured by an appropriate adjustment of the check nuts 126, 118.

Under still another shoemaking condition, calling for a greater sole edge extension in the forenart than in the shank, the forepart gage 22 is adjusted downwardly. by turning the screw 90, to a position below that obtained by the first described setting. With the mais still under the control of the crease guide and before the forepart gage eaches its operative position. However. even with a relatively rapid movement of the treadle rod 116 this depressing action of the forepart gage on the shoe, necessary to effect the desired increased sole extension in the forepart, is relatively gentle because the toggle links 102, 108 are closely approaching their fully extended relation and impart a relativey slow movement to the forepart gage as compared with that of the treadle rod. Immediately upon the engagement of the forepart gage with the shoe. the control of the shoe is shifted from the crease guide to as determined by the setting of the check nuts 126 relatively to the swivel block 128. When the rounding cut, after having been carried around the forepart, emerges into the shank and with the crease guide in such that the lesser sole edge extension in the shank is produced.

to its of the Now, as the rounding out emerges into the forepart and the treadle rod 116 is lowered the crease guide is lowered simultaneously w1th the part gage to obtain a downward shoe under a more gentle action than is obtained by the use of the forepart gage alone. That is, the first lowering of the shoe "is effected, before it is engaged by the forepart gage, by the crease guide when the toggle links 42, 44 move downwardly from their partially collapsed condition into their fully extended cond tion. This latter condition occurs when the forepart gage will have been brought into engigement with the shoe but before the forepart gage will have reached its operative 'position. Continued lowering of the treadle rod causes the completion of the advance of the forepart gage into its operative position, during which the motion of the crease guide is soon reversed by the downward collapsing movement of the toggle links 42, {14 which causes the crease guide to be retracted into its inoperative position.

When the rounding cut again passes from the forepart into the shank the above described movements of the gage and guide take'place in the opposite order. That is, during the preliminary retractive movement of the forepart gage the crease guide is lowered into engagement with and to take over the control of the shoe, but from this point, as'the forepart gage is retracted from the shoe, the crease guide is raised slightly to its operative position to permit the rise of the shoe relatively to the knife required to produce the lesser sole edge extension in the shank.
