- the vibrating edge setting tool or iron 10 which is arranged, as is usual in machines of the automatic kind above referred to, to be moved toward the edge of the sole of a shoe mounted on a jack 12 and is held against the sole edge while the jack 12 is moved to present different portions of the sole edge to the iron, is heated by gas jets issuing from tubes 16 and has bored into its upper face a recess 18 (see particularly Figs. 3 and 4) about one quarter of an inch in diameter and three sixteenths of an inch deep.
- the duct 22 opens into the groove 24 in the face of the iron near the top of the groove, and enters the recess 18 a little way above the lowermost portion of the recess so that a small well is formed at the bottom of the recess which retains a small amount of wax, as indicated in Fig. 4.
- the cohesion of the melted wax retained in the well and a fresh pellet resists the tendency of the fresh pellet to fall out of the recess, due to the vibration of the iron, and also promotes the conduction of heat to the pellet from the iron.
- the pellets may be supplied to the recess in the iron by various means.
- a screw 26 associated with a part 28 of the machine which moves with the iron 10 when the iron is moved by the operator into engagement with a sole edge by movement of a member 30 carrying the iron, as is usual in machines of the automatic type disclosed in United States Letters Patent No. 1,078,- 684 aforesaid, a plate 32 carrying an upwardly extending tube 34 which has at its upper end a funnel 36.
- the lower end of the tube 3% is positioned directly over and substantially in register with the recess 13 in the iron and the operator may drop a pellet of wax into the funnel 36 just before he moves the iron into engagement with the edge of the sole.
- the pellet which will have fallen into the recess will have melted or partly melted and the Wax will have commenced to pass through the hole 22 leading from the recess 18 in the iron to the groove 24 in the face of the iron and will be applied automatically to the sole edge during the edge setting operation. If the operator finds that the particular wax he is using does not melt quickly enough to be applied to the sole edge in a sufficiently fluid condition by the time that the edge setting operation commences, he can drop the pellet into the funnel slightly earlier and if, during the setting of an edge, he finds that for any reason wax isnot being applied to the sole edge sufficiently'generously, he can readily drop another pellet or part of one into the funnel.
- the tube 34 Since the tube 34 is hinged at 26 to the machine, it can be swung laterally away from the iron if it is desired to remove the iron, a friction spring 38 being provided on the pivot to bear against the plate 32 to retain the tube 34: in position over, or swung away from, the iron.
- the hole 22 and groove 24 in the face of the iron are, as shown in Figs..3 and 4, arranged on that side of the vertical center of the burnishing face 20 of the iron which is in advance of the work engaging portion of the face 20, considering the direction of relative traverse, during the final portion of the relative movement of the iron along the sole edge. This disposition of the hole and groove on the edge setting face of the iron leaves the center of the edge setting face unbroken and insures against any nnironed wax being left on the sole edge.
- the edge setting machine is provided with mechanism whereby a pellet of wax may be formed from a stick of Wax supported in the machine and conducted to the edge setting iron.
- Figs. 5*and6 there is mounted upon the part 28 previously referred to which moves with the ironr'a vertical tubular-holder 40 the lower end of which :is situated above the recess 18 in the iron.
- a support is provided on the holder 40 for a stick of wax 42 inserted into the upper end of the holder and comprises a finger 44 which is mounted upon a horizontal pivot 46 secured to the holder and has a depending arm through which passes a horizontal adjusting screw 48 threaded into the holder.

FINISHING MACHINE Filed July 15, 1932 s Sheets-Sheet s Patented Dec. 11, 1934 UNITED STATES PATENT OFFICE FINISHING MACHINE Application July 15, 1932, Serial No. 622,708 In Great Britain July29, 1931 26 Claims.
This invention relates to finishing machines and. is illustrated herein as embodied in a sole edge burnishing machine ..of the type disclosed in United States Letters Patent No. 1,078,684,
5 granted on November 18, 1913, in the names of F. B. Keall, J. Gouldbourn andA. E. J erram.
It is customary in finishing the sole edge of a shoe to apply a finishing medium consisting of or containing wax to the sole edge after it has been trimmed but before it is burnished or set. This treatment of the sole edge has commonly been effected manually by the operator either by rubbing a piece of wax against the sole edge or by applying a fiuid'finishing medium containing wax, or consisting of wax in a fluid state, to the sole edge by means of a brush as an operation in addition to, and distinct from, any involving the use of an instrumentality of a finishing machine.
It is apparent that finishing medium or Wax will be applied in unequal amountsto different shoes by the above method in accordance with variations in the absorbent properties of the sole leather, the consistency of the finishing medium or wax and the manner in which 'themedium or wax is applied by the operator.
In view of the above, important objects of the present invention are to save as much as .possible of the amount of time previously required by the operator to apply the finishing medium or wax to the sole edge and to insure that'a predetermined and adequate amount of finishing medium or wax will be supplied for each burnishing operation.
In accordance with the above object, the present invention contemplates the use of fusible pellets of finishing medium, or wax in solid form, which are of such size that either one pellet or a predetermined number of pellets may be utilized to provide an adequate, predetermined amount of finishing medium or wax for the complete treatment of a single shoe. Accordingly, one object of the invention is to provide an improved burnishing tool adapted for use in an oscillating edge setting machine, said tool having a'pellet receiving recess communicating with the burnishing surface and so constructed as to resist eifectively the tendency of a fresh pellet to fall out of the recess due to the vibration of the tool. To this end, the illustrated tool comprises a duct, which is arranged to carry wax as it is melted from a pellet to the burnishing surface "of the tool, and which opens into the'recess' ata point above the lowermost portion thereof whereby a small amount of wax is retained inthe recess.
Thus, a fresh pellet is effectively retained within the recess owing to the cohesion of the melted wax retained in the recess-and the fresh pellet. It is apparent, moreover, that the fusing of the fresh'pellet is more certainly effected as a-result of the heat of the tool being transferred thereto through the fluid wax retained in the recess.
In a machine in which, as in the'illustrated embodiment of the-present invention, a shoe support is mounted for movement to present successive portions of the soleedge of a shoe thereon to the operative surface of a tool such as a wax-applying tool, it is apparent that it is desirable soto apply wax, if that be the treating substance used,'to the sole edge that no unironed wax'is-left uponthe sole edge at the end of a movement of the work support which causes a transfer of the point of operation of the tool along the sole edge. To this end and in accordance with another feature of the invention, the above-mentioned duct inthe illustrated tool is arranged to open into the operative surface of the tool at a point which isin advance of the portion of the tool which engages the work, whereby the sole edge being operated upon is successively treated with wax which flows from the duct'and is then burnished. The above result may also be obtained in a machine of the type disclosed in the above-mentioned Keall et al. patent, in which the shoe support is moved so that successive portions of the sole edge are moved alternately in opposite directions a predetermined number of times, by arranging the duct with reference to the part of the tool engaging the work so that the above-mentioned requirements are satisfied during the last movement of the tool along the sole edge.
Invention is to be recognized not only in the provision of novel means for facilitating the use of pellets in a sole edge finishing machine, but also in the provision in such a machine of means for forming the pellets themselves. Thus,'the invention also contemplates the provision, in a burnishing machine, of a tool, a holder for a stick of wax, means for forming pellets from the stick, and means for conducting the pellets from the holder to the tool. As herein illustrated, the pellet forming means is constituted by a shear member which is movable with respect tothe wax holder. Uniformity in the size of the pellets thus formed'is assured by the provision'in the illustrated machine of means for positioning the wax in the holder-with respect to the shear member; and in View of the various requirements, as to the amounts of wax necessary to treat a sole-edge, encountered in the manufacture of shoes of different styles and sizes, the above-mentioned positioning means preferably comprises an abutment which may be adjusted in accordance with the size of the pellet required.
It has been found desirable in some instances in the use of a machine of the type disclosed in the above-mentioned Letters Patent first to impart to a sole edge a preliminary edge burnishing operation before any finishing medium or wax is .applied thereto in order to improve the capacity of the sole edge to retain the finishing medium or wax or the appearance of the sole edge at the end of the burnishing operation. In the machine in which the invention is illustrated as embodied, the forming of the pellet is effected whenthe machine is started and, in order that a machine of this type may be operated as described above, it is apparent that the pellet must be prevented from passing to the tool until the machine will have time to operate to some extent on the entire sole edge. To this end and in accordance with another feature of the invention, means is provided in the illustrated machine for arresting in the holder the pellet severed from the stick of wax, and means for moving the last-mentioned means is provided to allow the pellet to be conducted to the tool when it is desired to apply wax to the sole edge. As herein illustrated, the abovementioned means for arresting the pellet is constituted by a slide arranged normally to interrupt the passage of the pellet from the holder to the tool, the slide being operated by means which is actuated by operator-controlled means the movement of which starts the machine and causes the shear member to sever a pellet from the stick of wax in the holder.
These and other features of the invention will now be described with reference to the accompanying drawings and will be pointed out in the appended claims.

In the form of wax supplying device shown in Figs. 1 and 2, the vibrating edge setting tool or iron 10 which is arranged, as is usual in machines of the automatic kind above referred to, to be moved toward the edge of the sole of a shoe mounted on a jack 12 and is held against the sole edge while the jack 12 is moved to present different portions of the sole edge to the iron, is heated by gas jets issuing from tubes 16 and has bored into its upper face a recess 18 (see particularly Figs. 3 and 4) about one quarter of an inch in diameter and three sixteenths of an inch deep. The recess 18, when the iron is in its operative position in the machine as seen in Fig. 1, is arranged to receive a pellet or piece of wax which is to be applied to a sole edge and which in size is suflicient for the burnishing operation on the sole edge of one shoe. The pellet of wax which is received in the recess is heated by the heat of the iron and the wax melted from the pellet passes from the recess 18 to the burnishing face 20 of the iron through a small duct 22 which leads downwardly from the recess 18 to a groove 24 in the face 20 of the iron. The duct 22 opens into the groove 24 in the face of the iron near the top of the groove, and enters the recess 18 a little way above the lowermost portion of the recess so that a small well is formed at the bottom of the recess which retains a small amount of wax, as indicated in Fig. 4. The cohesion of the melted wax retained in the well and a fresh pellet resists the tendency of the fresh pellet to fall out of the recess, due to the vibration of the iron, and also promotes the conduction of heat to the pellet from the iron.
The pellets may be supplied to the recess in the iron by various means. In the construction illustrated in Figs. 1 and 2, there is pivoted on a screw 26 associated with a part 28 of the machine which moves with the iron 10 when the iron is moved by the operator into engagement with a sole edge by movement of a member 30 carrying the iron, as is usual in machines of the automatic type disclosed in United States Letters Patent No. 1,078,- 684 aforesaid, a plate 32 carrying an upwardly extending tube 34 which has at its upper end a funnel 36. The lower end of the tube 3% is positioned directly over and substantially in register with the recess 13 in the iron and the operator may drop a pellet of wax into the funnel 36 just before he moves the iron into engagement with the edge of the sole. By the time the iron has actually engaged the sole edge and the edge setting operation has actually commenced, the pellet which will have fallen into the recess will have melted or partly melted and the Wax will have commenced to pass through the hole 22 leading from the recess 18 in the iron to the groove 24 in the face of the iron and will be applied automatically to the sole edge during the edge setting operation. If the operator finds that the particular wax he is using does not melt quickly enough to be applied to the sole edge in a sufficiently fluid condition by the time that the edge setting operation commences, he can drop the pellet into the funnel slightly earlier and if, during the setting of an edge, he finds that for any reason wax isnot being applied to the sole edge sufficiently'generously, he can readily drop another pellet or part of one into the funnel. Since the tube 34 is hinged at 26 to the machine, it can be swung laterally away from the iron if it is desired to remove the iron, a friction spring 38 being provided on the pivot to bear against the plate 32 to retain the tube 34: in position over, or swung away from, the iron. The hole 22 and groove 24 in the face of the iron are, as shown in Figs..3 and 4, arranged on that side of the vertical center of the burnishing face 20 of the iron which is in advance of the work engaging portion of the face 20, considering the direction of relative traverse, during the final portion of the relative movement of the iron along the sole edge. This disposition of the hole and groove on the edge setting face of the iron leaves the center of the edge setting face unbroken and insures against any nnironed wax being left on the sole edge.
In the second illustrative construction aforementioned the edge setting machine is provided with mechanism whereby a pellet of wax may be formed from a stick of Wax supported in the machine and conducted to the edge setting iron. As shownin Figs. 5*and6, there is mounted upon the part 28 previously referred to which moves with the ironr'a vertical tubular-holder 40 the lower end of which :is situated above the recess 18 in the iron. A support is provided on the holder 40 for a stick of wax 42 inserted into the upper end of the holder and comprises a finger 44 which is mounted upon a horizontal pivot 46 secured to the holder and has a depending arm through which passes a horizontal adjusting screw 48 threaded into the holder. The stick of wax is -adapted to rest upon and be supported by the inner end of the finger 44, as shown in-Fig. 6, and by rotating the screw 48 the inner end of the 'fingerand therefore the stick of wax can be raised or lowered in the'channel of the holder to regulate the amount of wax cut from the stick in the manner hereinafter described. A spring 50 maintains the depending arm of the finger in contact with the head of the screw 48. A knife 52, having an opening in it through which the lower end of the stick of wax normally passes, as shown in Fig. 6, is mounted to slide in a horizontal guideway just above the finger 44 and is adapted to be moved across the channel in the holder to shear a pellet of wax from the lower end of the stick 42 supported on the finger 44. To enable the knife to be moved in this manner, the knife has a horizontal slot 54 formed in it within which slot is received a pin 56 fast on one end of the wire 58 of a Bowden cable 60, the other end of the'wire of which cable, as shown in Figs. 5 and 8, is connected to the lower end of a small lever v62 which is mounted on a fixed horizontal pivot 64 and carries a roll 66 at its upperend. The lever 62 is arranged to be rocked by contact with a hand operated control member or lever 68 corresponding to the element 290 in the above-mentioned United States Letters Patent No. 1,078,684 with 'which automatic edge setting machines of this type are provided to cause the edge setting iron to move toward the shoe and to cause the edge setting operation to commence. When the lever 68 is swung by the operator in a counterclockwise direction into the position it occupies as seen in Fig. 5 to commence an edge setting operation, the edge setting iron will be approaching the sole edge; and as this movement of the lever 68 continues the lever 62 will be rocked in a counterclockwise direction, as indicated in Fig. 5, to cause the Bowden cable-58 to draw the knife 52 across the holder 40 and to sever a pellet of wax from the lower end of the stick of wax 42, a spring '70 behind the knife 52 serving normally to take up the lost motion in the pin-and-slot connection between the knifeand the pin 56. The pellet of wax cut from the stick will be carried with the knife as it moves across the holder 40 away from over the finger 44 until it ceases to be supported by the finger 44 and can fall through an enlargement 72 formed in the channel in the holder .40 below the knife. When this happens the wax pellet will fall down by gravity through the channel in the holder and will be guided by it into the recess 18 in the upper face of the iron 10. Thus there is provided means which are actuated through the oontrolmember or lever 68 to cause a pellet of wax to be supplied to the iron just as the latter is moving into'engagement with the sole edge.
It may sometimesbe desired notto supply wax to the iron by the means last described when commencing an edge setting operation on -a shoe and when this arises the operator may, before heswings :the control member .or lever 68 to bring the iron into 'operationzona shoe, swing a hand :lever.74=:against which the knife is urged by: the
spring '70upwardly about its pivot '76 into a substantially vertical position to cause a nose or cam piece '78 on it toslide the knife across the :chan
nel in the holder 40 after having lifted the stick of wax upwardlya little in the holder to avoid cutting off any wax from the stick during such movement of the knife. The stick of wax is thus supported by the upper face of the knife 52 until the hand lever '74 is moved downwardly again, such movement of the knife taking place, due to the pin-.and-slot connection between it and the Bowden wire cable 58, without operating this cable. When, after the hand lever 74 has been moved into its vertical position, the control lever68 is swung to cause the iron to come into operation on the shoe, the lever 62 will be rocked about its pivot '64, as described above, by the control lever 68, but the pin 56 on the end of the .Bowden wire cable 58 will, during such rocking apply wax. to it and then to set or burnish the edge. Means is shown in Fig. 6, in addition to that already described for cutting oif a pellet of wax from the stick 42 as the iron moves toward the sole edge, for enabling the supply of a pellet to the iron to take place automatically at the end of the first relative traverse of the iron and sole edge without stopping the machine. To this end-a slide 86 having an opening 62 in it is mounted to move in a horizontal guideway in the holder 40 below the knife 52 in a manner hereinafter described. -A hand lever 84 mounted on a horizontal pivot 86 has a nose piece or cam on it which, when the lever occupies a substantially horizontal position, causes the opening 82 in the slide to remain in'alinement with the channel in the holder 40. The hand lever and slide occupy this position when it is desired that wax shall be supplied to the setting iron as the latter is moving toward the sole edge in the manner previously described, so that a pellet of wax .cut from the "stick may fall through the channel in the holder '40 and through the opening 82 in the slide, a
spring 88 being mounted behind the slide 80 as shown in .Fig. 6 to urge the latter to the left. When, -however, the hand lever 84 is swung down Wardly into a substantially vertical position as shown in Fig. 6, the slide is moved by the spring so far to the left that the opening 82 in it is brought substantially out of alinement with the channel in the holder 40, and therefore a pellet of 'cut off from the stick by the knife 52, after moved into its substantially vertical position be fore the control lever 66 is moved to commence the 'edge setting operation, and means is provided for bringing the opening 82 once more into line with the channel in the holder 40 at the end of the first traverse. Such automatic edge setting machines as have been referred to include a rocking member such as is designated 322 in the specification of the Letters Patent No. 1,078,684 above mentioned, which is associated with the mechanism for determining the number of traverses which the iron is to make around the sole edge, and this member is given a rocking movement through a substantial angle at the end of each half traverse of the machine. It is this rocking movement of the member 322 which is made use of in the illustrative form now being described to move the slide toward the right once more, after the hand lever 84 has been swung downwardly, to bring the opening 82 into alinement with the channel in the holder 40 at the end of the first traverse to allow a pellet of wax cut off by the knife 52 and supported on the slide 80 to fall into the recess 18 in the iron at the end of the first relative traverse of the iron and sole edge. This rocking member, as indicated at 89 in Fig. 5, has an arm 90 which moves downwardly at the end of each half traverse of the machine and upwardly at the end of each complete traverse. A bell-crank lever 91 is arranged to be engaged and rocked by the arm 90 as the arm moves upwardly at the end of the first relative traverse of the edge setting iron as indicated in Fig. 5. One end of the wire 92 of a Bowden cable 94 is secured to the lower arm of the bell-crank lever 91 and the other end of this wire is secured by a pin-and-slot connection similar to that referred to in connection with the knife 52 and the Bowden cable 60 to the slide 80. At the end of the first relative traverse of the iron along the sole edge the rocking member 89 will be moved in a clockwise direction as seen in Fig. 5 and the arm 90 will abut against a pawl 96 which. although pivoted on the upper arm of the bell-crank lever 91, will cause the lever 91 to be rotated in a counterclockwise direction. Thus, by means of the cable 92 the slide 80 is drawn to the right until the opening 82 comes into alinement with the channel in the holder 40, allowing the pellet of wax which was cut off from the stick 42, and was resting on the slide 80 in the manner previously described, to fall downward into the recess 18 in the edge setting iron. The pawl 96 is so mounted on the lever 91 that it can swing yieldingly downwardly about its pivot from the position in which it is illustrated in Fig. 5 without rocking the lever 91 and when the arm 90 in its downward movement (Fig. 5) moves so far that it slides out of contact with the pawl, the latter is yieldingly returned to its original position; but it cannot rock upwardly about its pivot relatively to the lever 91 from the position shown in Fig. 5.
When the two hand levers 74 and 84 are both in horizontal positions, the operation of the mechanism will be to cause the knife 52 to cut off a pellet of wax from the stick and to allow it to fall into the recess 18 in the iron as the iron moves into contact with the sole edge at the beginning of the operation on a shoe, since the opening 82 in the plate 80 is maintained in alinement with the channel in the holder 40 by the hand lever as; but if the hand lever 84 is swung downwardly as above described, before the control lever 68 is moved by the operator, while the pellet of wax will be cut off from the stick 42 by the knife 52 as the iron moves into engagement with the sole edge, it will be allowed to fall into the recess in. the iron only at the end of the first traverse of the iron around the sole edge.
