To all whom it may concern.'

Be it known that I, VILLIAM J. N Esrrr, acitizen of the United States of America, residing at Los, Angeles, county of Los Angeles, State of California, have invented a certain new and useful Heel-Cutting Apparatus; andI do hereby declare the following to be a full. clear.- and eXact description of the invention, such as will enable' others skilled in the art to which it appertains to make and use the same.

This invention relates toimprovements in heel cutting apparatus, and it has. for one of its objects to provide a novel and improved construction inv which both the cutter and the shoe holding device are mounted on a cross arm which is adapted for ready mounting on a supporting pedestal or onthe frame which is already in use and carries other devices for operating on shoes in doing repair work.

Another object of the invention is to provide a novel and improved shoe holding device.

Further objects of the invention are to provide a novel andv ilnproved heel cutting apparatus which. is practical and. commercial, simple and compact in construction, easy to operate, convenient and economical to use, and in which the parts and devices are easily adjustable t0 suit conditions and to make all of the desired straight or angular cuts through the heel.

lVith the above and other objects in view the invention may be said to consist in the provision ofthe novel` and advantageous features and in the novel and improved construction, arrangement, and combination of parts and devices as will be apparent from the claims and from a careful consideration of the following description of the` preferred,construction of the improved apparatus, taken in connection with the accompanying drawings in which Figure 1 isa side elevational view of the improved apparatus disposed on the frame which carries other devices for doing` repair workon shoes; Fig. 2 is a side lelevational view of theapparatus disposed on a supporting pedestal; Fig. 3 is a broken sectional view taken on the line 3-3 of Fig..

Referring to the drawings, the crossarm 15 has adjustably mounted at the ends thereof the mounting 16 for the circular saw 17, and the adjustable mounting 18 for the shoe holdingdevice 19. The crossarm 15 is provided on its underside with the downward extension 20 which is provided with the groove 21 and is adapted to t in the socket 22.

The mounting 16 consists of the bifurcated bracket 28 which is provided at its upper end with the bearings 24 and is provided at its lower end with the stem 25 which is slidably fitted in the guideway 26 at one end of the crossarml. The sprocket wheel 27 is feathered on and operated to drive the shaft 28 which is fitted in the bearings 24 and. has one end suitably attached to the circular saw 17. A set screw 29 on-the erossarm 15 is adapted to engage the stem 25 toloek the mounting 16 in adjusted. position on said crossarm.

The adjustable mounting` 18 consists of the stem 80 which has tiltablj7 mounted on its upper end the platform 31 on which is slidably mounted the table 32 on which is pivotally mounted the plate 33 which has thereon the adjustable bar 34 whichcarries the shoe holding device19. The platform 31has one end of its lower bifurcated part mounted on the pivot 35 on the stein 30, and it has the other end provided with the curved `slots V3G through which and the stem 30 passes the bolt 37 so that the platform can be tilted sidewise of the circular saw 17 and1locked in adjusted position. The table'32qis-provided on its underside with the dovetail guide 38 which is slidably fitted in a corresponding guideway inthe upper partcf the platform 31 so that :the table 32 can be. movediparallel to the circular vsaw 1'?.Y The table 32 has on its flat upper side the pivot 39`to which is connected the plate lll@ 33 so that the latter can be turned to 'turn the bar 34 and consequently the shoe holding device 19 at an `angle to the circular saw. The bar 34 is disposed parallel to the circular saw 17 and is provided with a lateral dovetail guide 40 which is fitted in a correspondiug guidoway in the upper part of the plate so that the bar 3ft and consequently the shoe holdingl device 19 can be moved laterally toward or away from 4the circular saw 17. The plate 33 has on its rear the extension 41 which has thereon the pivot 42 to which is connected the rear end of the lever 43 which has its forward end provided with the handle 44 and which is provided with a slot 45 through which extends the pivot 46 on the guide 40 so the bar 34 and consequently the shoe holding device can be moved toward or away from the circular' saw 17 by swinging` the lever 43 to the right or to the left. The lever 43 has thereon the pivot 47 on which is mounted the latch 48 which is pressed by the .spring 19 and adapted to engage the teeth 50 on the forward end of the plate The latter can be turned on the pivot 39 by means of the handle 51 which has thereon the pivot 52 on which is mounted the latch which is pressed by the spring 54 and adapted to engage the teeth 55 on the table 32 to lock the plate 33 in adjusted position. The. stein 30 slidably fitted in the guideway 56 which is provided at onerend of the crossarin 15, and the latter has thereon the set screw 57 which is adapted to engage the stein 30 to lock thelatter in adjusted position,

The shoe holding device 19 consists of the similar jaws 58 which are mounted on the pivot 59 on the depending lug 60 which is provided on the bar 34; said jaws 58 having adjacent edges 61 thereof formed and adapted to :[it in the crease between the heel seat and the heel 62 of the shoe 63. VThe .jaws 58 are provided with downwardly converging extensions 64 between which is interposed the roller 65 which is mounted on the pivot 66 on the arm 67 which latter is mounted on the pivot 68 on the lever 69. The latter has a handle 70 at its forward end and has its rear end mounted on the pivot 71 on the, lug 72 at the rear end of the bar 34. A spring 73 suitably connected to the bar 34 and bearing against the underside of the lever '69 is adapted tonormallyhold the lever 69 and consequently the roller 65 in the raised position so that the jaws 58Y are normally inthe full open position.

On the4 pivot 74 between the lugs 7 5 and 7 5 on the bracket 23 is mounted the lever 76 which is provided at its lower end with the handle 77 and has at its upper end the j yoke 78 which 'is provided with slots 79 into which extend the pins 8O on the ring 81 whlch is loosely mounted between Kthe colvice 19. to adjust thefheel 62 laterally towa rd or away from the circular saw 17 ,Y the latter when it is found more convenient can be adjusted relatively to the heel 62 by operating the lever 76 to move the shaft 28 and consequently the circular saw 17. The lever 76 has thereon the lugs 84 and 85 on which is slidably mounted the dogV 86 which is adapted to engagetheteeth 87 on the lug to lock the lever 76 and thus the circular saw 17 in adjusted position. A link 88 is pivotally connected to the dog 86, and the angular operating lever 89 which latter is mounted on the pivot 90 betweenthe lugs 91 and 92 on the lever 76. A spring 93 which bears against the lug 84 anda shoulder 94 on the dog 86 is adapted to normally press the dog 86 into engagement with the teeth 87.

'A stop 94 on the platform 31 is adapted to limit the rearward movement of the table 32.

As seen in Figs. 1, 3 and 4, the socket 22 may be suitably attached to the bar 95 on the usual framework 96 which has mounted thereon other devices for doing repair work on shoes; or, as seen in Figs. 2 and 9, said socket 22 may be suitably arranged on the upper part of the supporting pedestal 97. The socket 22 has thereon the set screw 98 which is adapted to extend into the groove 21 to lock the crossarm 15 in adjusted position.

From the foregoing the construction7 manner of use, and the advantages of the improved apparatus will be understood by thoseskilled in the arm. 1t will be seen that the cross arm 15 can be readily mounted on a suitable support or on the framework which carries other devices already in use for doing repair work on shoes. The mounting 16 for the circular saw 17 and alsothe mounting 18 for the shoe holding device 19 admit of adjustment as may be required to suit conditions in installing and using the apparatus. After placing the heel part of the shoe 63 between the jaws 58 the lever 69 is moved downwardly to cause the roller 65 to move against the extensions 64 to move the edge portions 61 of said jaws into the crease between the heel seat and the heel 62 of the shoe 63 so that the shoe 63V is held clamped by said jaws.l To make a straight cut through the heel 62 the lever 43 is operated to move the bar 34 and consequently the shoe holding device 19 at a right angle to the circular saw l17 according to the amount that is desired to" cut off of theheel 62, or if found more convenient, themlever is desired to make an angular cut longitudinally of the heel 62 the heel holding device 19 is turned to the desired angle to the circular saw 17 by the adjustment of the pivoted platform 31. When it is desired to make an angular cut transversely through the heel 62, the plate 33 is turned by the handle 51 to have the heel holding device 19 at the desired angle to the circular saw 17. After adjusting the heel holding device 19 or the circular saw 17 according to the cut that is to be made through the heel G2, the table 32 is moved to effect movement of the heel 62 past the circular saw 17 to have the latter cut said heel.

The construction which has been particularly illustrated and described admits of minor changes and modifications-wherefore the right is reserved to all such changes and modifications as do not depart from the spirit and scope of the invention which is defined in the appended claims.
