Application filed June 16, 1919, SerialNo. 304,617. Renewed November 21, 1925.

This invention relates to machines for breasting heels and particularly to machines for breasting heels after they are attached to their shoes. i

5 Commercial machines for this purpose have usually been organized to support a shoe with its shank in a position determined by the height of the last and with a knife which cuts toward the shank and is arrested by disconnecting it from its actuating mechanism when its edge has reachedthe shank. While machines thus organized have been satisfactory when properly built and'adjust ed, they involve a delicate knife controlling mechanism which is apt to get out oforder. t is obviously simpler to give the knife a constant stroke and to position the shoe by means engaging the shoe shank and located with its shoe engaging face at the limit of the knife stroke. This also has been attempted but in prior machines of this type the work supports have been movable in the longitudinal median plane of the shoe into and out of operating position, and it Was necessary either to give the shoe an abnormal amountof vertical movement to enable the heel to clear the shank engaging stop or else it was necessary to provide more or less complicated mechanism to move the stop out of the Way of the heel during introduction of the shoe into operating relation to the brcasting means and during its removal from such relation. r i

An object of this invention isto provide an organization in Whch the shank stop may remain in fixed position and the shoe may be introduced into and removedfrom opera.- tive position With a minimum of vertical movement. v

A feature of the invention consists in an organization comprising, in combination with heel breasting means, a fixed shank rest or stop-and a shoe support movable transversely of the shoe or laterally "of the longitudinal axis of the shoe into and out of operative relation to the stop and breasting re ans. Since a reciprocating knife is usually employed as the breasing means, the movement of the shoe support maybe defined as being in a plane parallelwith the plane of the knife or with its plane of movement and also as in the direction of extent of the knife edge. The shank stop extends transversely of the shoe shank so that move.

ment of the shoe support is also in the direction of extent of the shank engaging face of the istopi As shovvmthe support is depressible to permit lasts of varying height to be positioned. under the stop and novel mean is provided for raising the shoe against the stop and for sustaining itduring the operation ofthe breasting means.

The breast face of the heel is usually formed at a moreor less acute angle to the face of the shank, this angle'being known as the pitch of the heel breast. To secure the proper pitch of the heel the shoe is usually located by movement in its longitudinal median plane relatively to the knife so that the knife will form the breast face at the proper angle to the shank, The pitch is usually determined by a tread rest- Which engages the tread face of theheel. In many heels, hOW- ever, the tread face has not sufficient area accurately to determine the position of the heel.

A further featureof the present invention consists in? an organization comprising a knife acting in the direction of the height of the .heel and novel means for engaging both the tread face of the heel and the tread face of the forepart for determining the location of the shoe in its longitudinal median plane to secure the proper pitch of the heel.

- ranged for aoiustment together to vary the position of the shoe in its longitudinal median plane relatively to the knife, and hence to'vary the pitch of the heel breast formed by the knife.

1 Since, in orderto vary the pitch of the heel, it is necessary to tip the last in its longitudinal median plane, the direction of the pin hole. in the last Will bechanged as the shoe is'tipped. Accordingly, a further feature of :the invention consists in means constructedand arranged to enable the last pin tobe selfaccommodating to the varying direction of the pin hole of the last as it is tipped to vary the pitch of the heel. Preferably the last pin is movable freely about necessity of making adjustments.

a center located substantially in the tread face of the heel. To ensure such movement of the pin, the pin support, as herein shown, is supported on upwardly converging links which allow a free movement of the pin about a center located as described.

determine the position of the shoe in the be held against depression by means which engaging means.

:operative position longitudinal median plane in which it should be held during the breasting operation, and further since the front edge of'th-e tread rest is employed as a gage to position the heel longitudinally and relatively to the knife. V 1

Accordingly a feature of the invention consists in an organization including a normally depressible work support and normally depressed tread engaging means, a fixed stop, means for locking thesupport with the shoe pressed against the stop, and means for applying shoe holding pressure to the tread tion a last of any height'may be placed on the support, the support depressed to permit movement of the shoe beneath the stop and beneath the tread engaging means. The shoe, upon being released, is raised by the depressible work support against the stop and against'the tread engaging means, which latter are raised by the shoe and the shoe held yieldingly against both the stop and the tread engaging means so that it may be shifted longitudinally or laterally, using the front edge of the tread plate as'a gage. The shoe support locking means is next released to hold the shoe against the stopandagainst depression during the action of the knife. If the shoe is found to be properly positioned for the breasting operation, the machine is started, whereupon additional pressure is applied to the tread engaging means and the knife cuts a chip from the breast face of the heel until its edge is in'the plane of the shoe-engaging face of the stop and then retracts.

It is important that the shoe be raised to press it firmly against the stop and that it acts irrespectively of the height of the last, and also that the operator be relieved of the work of raising and holding the shoe. Accordingly, another feature of the invention consists in power means under the operators control for .raisingand locking the shoe in 1rrespect1vely of the height of the last. In the organization With such an organizashown power is stored up in a previous cycle of the machine and is released in the following cycle to impel the actuator to cause the shoe to be raised and held against the stop. As shown herein the actuator consists of co operating wedge members for raising and holding the shoe and are actuated by a spring which is energized by power in one cycle of the machine and held by a latch which is manually releasable "in the next cycle to cause the wedge members to be actuated.

After releasing the actuator it may be found that the shoe isnot properly posi tioned for the breasting operation, and it is desirable to provide means for releasing the clamping pressure of the actuator against the stop to allow repositioning of the shoe before the machine is started. Accordingly a featnreof the invention-eonsists'in means for releasing or re-energizing the actuator to permit repositioning the shoe before it is again clamped and the machine started.

These and other features'of the invention, including novel details of construction and combinations of parts, will appear more fully from the following detailed description when read in connection with the accompanying drawings and will be pointed out in the appended claims.

Referring to Fig. 1 of the drawings, the numeral '2 indicates the frame of the machine in thenpper portion of which is mounted for vertical reciprocation a knife slide 4. To the lower end of the slide is pivoted at 6 a connecting rod 8, the lower portion of which receives the pin 10 of a crank 12 on the main shaft 14 of the machine." The shaft 1 is turned by apulley 16' through a one-revolution clutch acting to stop the shaft with the slide 4 the upper limit of its movement. On the knife slide is a knife clamp comprising jawsT17, 18 (Figs. 8 and 4) which are operated to clamp a knife 19 by means 'of a right and left screw 20, the knife clamp construction being substantially similar to that described in my prior Patent No. 1,191,622 granted July 18, 1916. The shoe is located relative- 1y to the constant lower limit of the knife stroke by an abutment or stop21 (Fig. 2) which is adjustably fixed to the machine frame 2. The stop 21 is fastened at 22 to a block 24 arranged to slide forwardly and backwardly of the machine on a member and is held in place by a screw 28 engaging a slot in the block 24; The member is arranged for vertical adjustment by having downwardly extending

portions

29, 30, guided in grooves in the frame, which portions are slotted to receive

screws

32, 34.

Heels are formed by the breasting oper ation with the breast ata greater or less acute angle with the shank portionof the shoe. The amount of thi' angle determines the so-called pitch of the heel breast; In the machine of the present invention this angle is determined by a plate or rest 10 (Figs. 2 and engaging the tread face of the heel and a forepart rest 50 engaging the shoe bottom in connection with a shoe support 60 which permits movement of the shoe about a center located substantially in the tread face of the heel. The tread plate 40 is removably secured to a block 11 (Fig. 5) pivoted at 42 to a slide 43, the block having an upward projection 44: which is engaged by a screw 4-5. The block and plate are thus angularly adjustable about the pivot 42. A spring 46 is arranged normally to hold the projection 44 against the screw 15 but permits the plate to be swung down out of the way of the knife when it desired to remove or replace the knife 19.

The f-orepart rest 50 comprises a bar 52 which passes through a stud 54: held in the block l1 by a set screw 56. The bar is bent at its outer end to form the forepart rest 50 as shown. The bar 52 may he slid longitudinally in the stud 54; to locate the rest50 properly for different lengths of shoes and is held in adjusted position a set screw 55. By loosening the set screw 50 the stud may be turned to locate the rest 50 vertically for lasts of different spring. Normally, however the rest 50 is in the plane of the shoe engaging face of theplate 40.

The shoe support 60 earn es the usual last pin 62. The post 60 is relatively short and is fixed to a base G lwhich; its forward and rearward ends, is connected at 06 and 68 to links 7 0 and 72 respectively. The link 70 lies between two upstanding supporting arms 73. 7 1 (Fig. 1) to which it is pivoted at 70 and the link 72 is similarly pivoted a 78 to supporting arms one of which is shown at i9 (Fig. 2). Thearms are arefershoe and guides the ably formed in pairs connected at the bottom, the outer pair being 73, 79, and the inner pair being 74, and one, not shown, but located directly behind the arm 7 9 in Fig. 2- These pairs. are secured to a head 82 by screws 84- passing through the connecting portion of one pair, through the head 82 and threaded into the connecting portion of the other pair. It will be noted that the

links

70, 72 are not parallel but converge upward- 1y, their inclination being such that as the base 6 1- swings on the links 70, 7 2 the last pin 62 on the post 00 will swing to a less degree and by extending the line of the post 60 upwardly to the plane of the tread face of the sole a point will be found which will have substantially no movement lengthwise of the shoe. The swinging links, however, allowthe angular position of the last pin to change and to accommodate itself to the position of the last in a vertical plane as determined by the tread plate or by the tread plate 40 in connection with the sole rest 50.

The head 82 is fixedto a jack rod arranged for vertical adjustment in a jack post 92 by a hand wheel 94. A lower p01 tion 96 of the jack post slides up and down in a cylinder 100 being normally sustained therein by a spring 102 located in a longitudinal bore in the portion 96 and resting at its lower end against the bottom of the cylinder 100. Between the post 92 and the portion 96 are two

joints

104, 106 arranged at right angles to each other, the one. 10 1, permitting movement of the post longitudinally of the shoe and the other. 106, permitting movement of the post transversely of the shoe. Movement of the post in these two directions is limited by a bail-like member 107 surrounding the post and secured in a projection 108 from the frame by set screws 109. Inward movement of the post laterally of the shoe is limited by a face 110 on. the post adapted to engage a correspond 111;); face on the projection 108 which face extends in a direction longitudinally of the post when moved in that direction.

Considering the construction as thus far described. it will be seen that the shoe support may swing about the pivot 106 laterally of the shoe into the position shown in dotted lines in Fig. land a shoe placed upon the last pin 62. his lateral movement of the shoe support therefore causes movement of the shoe in plane parallel with the plane of the knife 19and with its plane of movement-as well in the direction of extent of the knife edge and in the direction of the shoe engaging face of the stop 21. The shoe support may then be depressed by com pressing the spring 102 a little more than enough to clear the stop 21 and the support and shoe swung beneath the tread plate 40 and forepart rest 50 which are adjusted vertically so that the shoe will engage them first and then engage the stop 21 as the shoe is raised, the plate and the sole rest 50 being held down at this time only by the weight of the connected parts. When the shoe is released by the operator the spring 102 will raise the shoe against the tread plate 40 and stop 21 which are adjusted in the longitudinal median plane of the shoe to position the shoe heel with relation to the direction of movement of the knife so that the heel breast will be formed with the proper pitch or angle relatively to the shank. The

links

70,72 will permit self-accommodation of the angular direction of the heel pin 62 to correspond to the position of the pin hole of the last of the shoe thus determined. The shoe support may be moved longitudinally of the shoe about the pivot 104 to position the shoe longitudinally relatively to the forward end of the tread plate 40 which serves as a gage to indicate where the knife will engage the toplift. This construction has the distinct advantage that there is no necessity of depressing the shoe to cause the heel to pass beneath the stop 21 as is necessary in a construction where the shoe is moved longitudinally into and out of operative relation to the knife, since in this construction it is necessary only to depress the shoe slightly to bring the shank beneath the stop 21 and

treadrests

40, 50 as it is V swung in. The shoe is now positioned properly for the breasting out except that itmay be necessary to lift the shoe and jack slightly to bring the shank into engagement with the stop 21. The knife is of course adjustedto cut to the plane of the shoe engaging face of the stop 21.

After the shoe has been positioned in the machine it is necessary that the shoe be lifted andpositivel'y sustained and prefer- .ably pressed against the stop 21 before the machine is started. To effect this, the mechanism best shown in Figs. 1, 7 and 8 is provided. The portion 96 of the jackpost' is slotted to receive a series of three

floatingwedges

120, 122, 124. The lower wedge 120 rests in a groove formed in the top of the cylinder 100 and the wedge 124 bears on its upper face against the upper end of. the slot in the portion 96. Between these wedges is the wedge 122 which is anchored by a link 126 to a bracket 128 on the cylinder 100. This wedge 122 has no substantial movement longitudinally but by reason of its link connection to the bracket 128 may move vertically. The wedge 120 has an upturned end 130 connected by a link 132 to the wedge 124 and beneath the link 132 is a link 134 connecting both

wedges

120, 124 to'an operating'lever 136 fixed at its lower end toa rock shaft 138 and acted upon between its ends by a spring 140 to move the lever 136 toward the right (Figs. 2 and 7)v and ad- Vance the

wedges

120, 124 beneath and above the; wedge 122 respectively and cause the work support topress the shoe against the stop 21 and, other shoe positioning means 40 50' and to sustain it positively. The

wedges

120, 124 are held retracted until their operation is required by a bar 144 (Fig. 10) which is pivoted at one end to an offset 145 (Figs. 1 and 11) on the lever 136 by, a screw 146 and is engaged at its other end by a latch 148. The offset- 145 is strengthened (Fig. 11) by a strut 135 integral therewith and loosely pivoted on the shaft 138 with the lever 136 (Fig. 11). The latch 148 is released by a preliminary movement of a treadle lever 150 by which the power operation of the machine is controlled but which movement is insufficient to trip the clutch to 152 carries also an arm 160- which is held raised and locked with the stop arm 154 in stopping position by a

toggle comprising links

162, 164, the connecting joint of which is constructed to prevent its being bent beyond the position shown in Fig. 10-, the toggle being held in straightened position by a spring 165. The upper link 162 of the toggle has a projection 166 above and atone side of the point 163 where it is pivoted to the arm 160 which projection is engaged by a shoulder 167 on a member 168 pivoted at its lower end to the treadle lever 150.211; 151

and held toward the projection by a spring 124, causing the shoe support to be raised and the shoe to be clamped against the stop 21 and the positioning means 40, 50, the shoe being held clamped, during operation of the knife, by pressure through the inclined faces of'the wedges. The self-accommodating last pin adjusts it self to the position of the last as determined by these shoe positioning means. Further depresion of the treadle effects further movement of the roc r-shaft 152, causing the stop arm 154 thereon to be removed from heneath the stop projection'156 of the'clutch, thus allowing the clutch to go in and'the machine to start. The crank 12 then revolves and through the connecting rod 8 causes the knife to descend and cut a chip from the breast end of the heel. The knife transmitted is so adjusted by means of a nut 174 on a threaded stem 176 attached to the knife that when the crank 12 has reached a point 180 from its starting position and has imparted to the knife ltS'Il1&XlllltUl1 downward movement, its edge has reached the plane of the shoe shank as determined by the stop 21. During this movement of the crank it has engaged an inwardly and downwardly bent portion 178 of the member 168 and moved the member outwardly against the spring 153 enough to cause disengagement of the shoulder 167 from the projection 166. This allows .the

toggle

162, 164 to straighten under the influence of the spring 165 and restore the stop arm 174 and the latch arm 148 to their initial positions. As the crank 12 continues its movement a portion 180 of the connecting rod 8 extending below the crank pin engages an arm 182 (Fig. 8) on the rock-shaft 138 and rocks the shaft in a direction to withdraw the

wedges

120, 124 against the tension 'of the spring 140 and to move the end of the bar 144 into position to be engaged by the latch 148 which has been already released as described. When the crank has completed its revolution and restored the knife to raised position, the stop projection 156 engages the stop arm 154 and the clutch is thrown out to cause the machine to sto i It iiiay sometimes be desirable to withdraw the wedges after they have been released by partial depressionof the treadle in case the shoe is found to be improperly positioned. For this purpose a hand lever 186 is provided which lever is loosely pivoted on the rock-shaft 138 and arranged to engage the offset 145 (Figs. land 11) on the lever 136 and move the lever and hence the bar 144 in a direction to withdraw the wedges to release upward pressure of the shoe supportand allow the shoe properly to be positioned.

It is also important that additional downward pressure he applied to the tread plate 40 during the operation of the knife. For this purpose the slide 43 on which the tread plate is mounted is connected at its upper end through an adjusting screw 190 (Figs. 1 and 2) with a lever 192 pivoted at 194 to a bracket on the frame. A rod 196 is connected to the lever 192 between its ends and a pull on the rod acts through a. stiff spring 198 to press downwardly the slide 43 which is guided for vertical movement in a bracket 47 on the frame. The red at its lower end is pivoted at 200 (Figs; 6 and 12) to an arm 202 secured to a rock-shaft 204. On the rock-shaft 204 is an arm 205 having between its ends a roll206 which is engaged by a suitable edge cam 208 on the main shaft 14. Preferably the arm 202 has a web 207 (Fig. 12) extending toward the arm 205 and connected to it by a link 209. Thus positive action between the roll cam 208 and the rod- 196 is provided. When the cam revolves it applies pressure to the roll 206, causing the lever 202 to pull downwardly on the rod 196 and to act through the spring 198 to apply power pressure to the tread plate 40 and the shoe beneath it. When the machine is in stopped position the plate is held down only by the weight of the connected parts and is easily raised when the wedges operate to jack the shoe. In the preliminary positioning of the shoe the tread plate 40 is adjusted by turning the screw 190 for the height of the heel so that it rests lightly on the shoe and its front edge constitutes a gage for pcsitioning the heel for the cut of the knife in the usual manner, the shoe support being movable for this purpose about either of the

pivots

104, 106.

After the operation of the knife it sometimes happens that the chip is not entirely severed from the heel but clings to it by a few shreds at its lower edge and has to be torn off by the operator. In the machine of the present invention means is provided for insuring that the chip will be removed when the shoe is withdrawn from the machine. The stop 21 is provided with a chip engaging portion or offset 210 (Fig. 1) which lies in the path of the chip when the shoe support is swung laterally of the shoe in re moving the shoe from beneath the knife. During such movement of the shoe the chip, if it clings to the heel, is engaged by the offset 210 and torn away from the heel.
