Claims,

'mi machine as thatv just referred to, however, it

seldom occurs that more than one device of the entire machine is used at the same time. is particularly true of theV finishing device, such asfor instance buiers of the Naumkeag type, and `f this invention relates particularly tov the provision of a convenient finishing apparatus With which maybe employed a Naumkeag buiier.

The objectof this invention generally stated is. `to provide `improved mountings for a` shoej `goyiinishing device.

Anotherobject of this invention is to provide a shoe finishing device which may be moved into an inoperative position 'Where it Will not interfere with the other apparatus vvhich may be inV gsi the vicinity thereof;

`A further object of this invention is to provide ashoeiiinlish-ing device having an automatically controlled suction tube adjacent thereto.

A further .object of this invention is to'prox vide a shoe finishing device having a driving means adapted to` become automatically disen-v gaged .when the finisher has' moved into an inoperative position.

A more specic object of this invention is to `':A provide a shoe nishing device particularly 'for' use in a repair shop in which the movement of the finisher between operative and linoperative positions eifects an automatic control of the driving and suction mechanisms.

Other objects will become apparent to those skilled in the art when the following descrip-,- tion isfreadin connection with the accompanying drawing, in which:

Figure 1 is a view in end elevation of a shoe gynnishing device mounted upon the usual com-` bination machine of a shoe repair shop.

Figure 2 is a detailedvplan view shown particularly in section taken jalong line 2-2 of y IFigure `l, illustrating particularly `the mounting",`

5`5f-mounted upon a suitable supporting .stmctura` This 1 Which supporting structure is preferably movable relative to the main frame ofxthe machine, upon which the device is provided, such as for instance the. shoe finishing machine of a' shoe repair shop. In accordance with oneembodiment of the present invention, a supporting structure for theiinishing device is pivoted upon the main frame of the machine so that the finisher may be moved through a substantially vertical angle between an operating. and a non-operating position. In the illustrated embodiment, a drivingV mechanism for: the finishing device is illustrated as of the belt type, and it will be apparent that when the finisher is moved into its operative position, the tension upon `the `driving belt is sufficiently. increased so that the belt operates to drive the finisher, whereas when the finisher is in its non-operating position, the belt is suiliciently loosened that nol driving force is transmitted thereby.. Furthermore, in accordance with one embodiment of the present invention, a suitable suction device is provided adjacent the nisher and preferably movable with the supporting structuretherefor. The movement of the suction device with the supporting structure for the iinisher is utilized for automatically actuating a suitablecontrol valve for the suctionrdevice in ordery that the same may be openand operative when the liinisher is operated, but closed to'prevent a loss of vacuumwhen the finisher is in its non-operating position. f

Referring now particularly to the drawing, the iinisher of the present invention is ,shown mounted upon the usual supporting frame 1 of a finishing machine such as is generally employed in shoe repair shops.` In accordancewith thev usual practice such finishing machines for use in a shoe repair shop are provided with a driving shaft 2, extending length-arm-wise `thereof and upon the shaft 2'is usually mounted a plurality of such pulleys as 3 for transmitting` driving force to the various pieces of apparatus provided therealong. Near the upper end of the supporting frame 1, a suitable bearing or boss is preferably provided for receiving a shaft 4. Upon the shaft 4 the supporting arm or auxiliary frame 5 having a bifurcated end 6, may be pivotally mounted. On the opposite end of the supporting arm 5 from the pivot at 4, any suitable finishing device such as for instance a buiier of the Naumkeag type may be mountedas at 7. The end of the supporting arm 5 which receives the finishing device as '7 may be suitably formedfas of thebifurcated structure illustrated in Figure 1, in order to provide a convenient mounting forA the-'nishing device r7. Interposed between the respective arms of the supporting arm 5, a driving pulley 8 for the finishing device '7 may be provided. Mounted also upon the side of the supporting arm 5 is an idling 5 pulley 9, and a second idling pulley 10 may be suitably mounted upon the main frame 1 of the machine. A suitable driving device such as for instance a belt 11 may be provided for transmitting the driving force to the driving pulley 8 of the finishing device and such a belt 11 is preferabl trained over the idling pulleys 9 and 10. n

With the arrangement just described, it is apparent that the supporting arm 5 carrying therewith the finishing device 7 and the idlingpulley whereby the entire structure may be moved into the dotted position illustrated in Figure 1. A suitable stop such as for instance a lug 12 may be provided integral with the supporting arm 5 in order to determine the dotted line position thereof by engagement with a stationary part of the frame 1.

Such machines as the finishing machine of a shoe repair shop are generally provided with a 2.5;gsuction device, having outlets adjacent the various tools in order that the leather trimmings and grindings may be collected together in a suitable bag and in order to prevent the atmosphere in the room from becoming laden with fssuch grindings. Such a suction device is usually provided with a suitable header as. 13 leading to the suction apparatus and the collection bag. From the header 13, the various outlets lead to positions adjacent the various tools. In accord- 3533ance with the present invention, a iieXible tube such as 14 is suitably connected to the header 13 and leads to a position in which the mouth 15 thereof isv disposed adjacent the grinding element of the finisher 7. The mouth 15 of the sucedgtion tube is preferably secured to the supporting arm 5 by any suitable means such as for instance through a bracket 16. With the arrangement justdescribed, it is apparent that when the supporting arm 5 is moved between the operative po- 4559, sition illustrated in full lines, and the in-operative position illustrated in dotted lines in Figure 1, the mouth piece 15 of the flexible tube 14 is moved therewith as an associated part so that the mouth piece 15 is always disposed adjacent the Qiggrinding element of the finisher '7 regardless `of the position thereof.

Mounted in the mouth piece 15 of the suction tube 14, a suitable control valve such as for instance a butterfly valve 17 may be provided. It

qwill be understood that the butteriiy valve 17 comprises a disk which is preferably secured to a shaft-18, which latter may be journaled inthe walls of the mouth piece 15. In accordance with k the present invention, the shaft 18 preferably ex- Qftends through one wall of the mouthpiece 15 and at the outside end 19 thereof, a suitable weighted device such as an arm 20, having enlarged portions 21 maybe secured. It will be apparent that the enlarged weighted portion 21 will be readily responsiveto the action of gravity, and

accordingly asthe mouth piece 15 is moved between `the position illustrated in full lines of Figure 1 where the parts are substantially horizontal, and the position illustrated in dotted lines, 'Q 'jwhere'it approaches the ver-tical, the weighted portion of the arm 21 will operate to actuate the butteriiy valve 1'7 during such movement of the mouth piece l5 with the supporting arm 5 of the apparatus. 1 775g; In the roperation ofthe device just described,

9, may be rotated about the shaft 4 as an airis by the dotted lines in Figure 1.

it is apparent that when the supporting arm 5, with its associated parts is moved into position illustrated in Figure 1, the driving pulley 8 for the finishing device 'l will be considerably closer to the idling pulley 10 than when in the operative position illustrated in full lines. It will be readily understood that such relative movement of the pulleys 8 and 10 will eiiect a substantial decrease in the tension of the belt 11 and such relative movement may be so adjusted that when the supporting arm 5 with its associated parts is Amoved into the dotted line position, the tension on the belt 11A will be insufficient to transmit a driving effort to the pulley 8. In order, however, to prevent the belt 11 from becoming displaced with reference to thev various pulleys, when the tension thereon is released, suitable guards such as 22 for the pulley 8, 23 for the pulley 10, 24 for the pulley 9, and 25 for the pulley 3 are preferably provided in order to maintain the belt 11 in such position that upon movement of the supporting arm 5 into its operative position, the belt will be disposed in the position for driving engagement with the respective pulleys. It is apparent, therefore, that when the supporting arm 5 is moved into its inoperative position, illustrated by the dotted lines in Figure 1, the belt 11 will be automatically released from driving engagement with both the pulleys 8 and 3. Furthermore, as the arm 5 with its associated parts moves from the full line position to the dotted line position.

illustrated in Figure 1, it will be apparent that the arm 20, by virtue of the weighted portion 21, responding to the pull of gravity, will continue to extend in a substantially vertical direction. With the arm 20 thus remaining vertical, and the angle of the mouth piece 15 with the horizontal changing almost ninety degrees as illustrated in Figure 1, it is apparent that the butterfly valve 17 will be moved into such position that the opening through the mouth piece 15 will be blocked when the device is in its inoperative position illustrated Accordingly, there is provided. a mounting for a finishing device which permits the finishing device to be moved into an inoperative position which is out of the way and does not interfere with the operation of other pieces of mechanism which may be provided in the region thereof, butwhen it is desired to operate-the finisher, the same may be readily moved into convenient position illustrated by the full lines in Figure 1 and upon such movement the driving mechanism therefor is automatically engaged andthe suction mechanism is automatically set into operation.

limited to the specific details which'have been' hereinbefore described, nor to the use of the device of the present invention with a shoe finishing machine such as is employed in shoe repair shops, it being understood that the device has been described with'reference to such a shoe finishing machine merely for-the purpose of illustration.

Furthermore, it is to be understood that the use.

of such individual features and lsubcombination of features which do not depart from the spirit of the invention are, although not speciiicallydescribed herein, contemplated by and withinthe scope of the appended claims.
