SOLE-LEVELING MACHINE.

To all whom it may concern:

Be it known that we, CHANDLER L. PARKER and \VILLIAM C. CoLLYER, citizens of the United States, residing at Lynn and Reading, respectively, in the counties of 'Essex and Middlesex, respectively, and State of Massachusetts, have invented certain new and useful Improvements in Sole-Leveling Machines; and we 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 apperof sole leveling-machines which comprise a' tains to make anduse the same.

The present invention relates to sole leveling machines, and particularly to that class shoe supporting jack and a leveling roll mounted for relative movement to transfer the point of operation of the roll over the sole of. the shoe.

An object of the present invention is to improve the construction, arrangement and mode of operation of the leveling device or devices of this class of soles leveling machines with a View to increasingthe speed with which the leveling operation is performed and to securing improved results upon the sole.

' With the above object in "iew a feature of the pre: ent invention contem lates the provision in a sole leveling mac line pro 1 vided with a shoe supporting jack of means for exerting a rolling and a rubbing action upon the sole of ashoe'to level the same.

40 .fthereto. The rubbing action serves to The rolling action is the same as, that which is produced by the leveling roll or rblls' of vibrating roll sole leveling machines which are nowcommonly used, this roll'ing'action serving to press the sole, snugly against the bottom of the last and causeit 'to con'form smooth out the sole' and polish the surface thereof substantially the same manner as a rub stick when-used by an operator-fin leveling turned shoes- By subjecting 'the .sole to both a rolling anda rubbing. action, the; sole is .quickly pressed dowirupon the bottom of the last" and smoothed out-so as to, conform accuratelythereto and at the same."'tiine the tread surface of the sole is factory, and by the use of a roll the machine can be'constructed in a compact and simple manner. In order to causethe sole leveling roll to exert both a rolling and a rubbing action uponthe sole, the present invention contemplates vibrating the roll while in contact with the sole and locking the roll from rotation during its vibrating movement in one direction, the roll being free to rotate on 1ts axis during its vibrating movement in the opposite direction. The roll ,may be locked from rotation While moving in either direction but it is preferred to lock the roll Y during its movement toward the toe end of the sole as thereby the fibers of the sole may be acted upon in the same direction'as they are subsequently acted upon'in the operations of buffing and finally polishing the sole. Also when the machine is used upon soles provided with a channel in the tread v Specification of Letters Patent. Patented NOV. 9,1909. Application filed December 26, 1905. Serial No. 293,176. g

surface, the roll is allowed to rotate while moving in adirection tending to open up the channel flap and during its rubbing move 1nent. exerts a Wiping action upon the channel flap which lays it smoothly over the channel.

In the operation of sole leveling machines which comprise a sole leveling roll or rolls, difliculty is-experienced in causing the roll to act properlyupon ditferentstyles of shoes, andparticularly 'upon the shank portion of the sole. An object of the present invention is to provide a machine by which this difiicultyis avoided and by which the soles of difierent styles of shoes can be qulckly "and readily leveled in a satisfactory mannerl: With thisobject in view a feature of the present invention contemplates the provision, with a-shoe supportmg ack, of a palm rality of sole leveling rolls, and means for supporting the jack and rolls which permits .a'relative adjustment of the jack and rolls to bring any-roll into cooperative relation with the jack. In accordance with this feature of the invention a number of sole leveling rolls of different shapes and sizes may be provided, any one of which may be brought into cooperative relation with the spection of the accompanying drawings, in

which- Figure 1 is' a view in side elevation of a sole leveling machine embodying the same in their preferred form; Fig. 2 is a detail view in front elevation of the sole leveling rolls and of the mechanism by which they are supported in the machine; Fig. 3 is a view in end elevation of the parts illustrated in Fig. 2 looking toward the left; Fig. 4 is a view in end elevation of the parts illustrated in Fig. 2 looking toward the right; Fig. 5 is a cross sectional view of one of the leveling rolls taken on the line m-.'v of Fig. 6; and Fig. .6 is a longitudinal seetional view of the roll taken'on the line yy Fig. 5.

For convenience of illustration the several features of the present invention have been shown in the accompanying drawings as applied to a well-known form of vibrating roll sole leveling machine, which machine is disclosed in the patents to Gilmore No. 266,283, dated October 24, 1882, and

a No. 344,650 dated June 29, 1886.

,Referring to the drawings, 1 indicates the I shoe-supporting jack which is provided with a heel support 2, a toe support 3 and a roll receiver 4. This jack is pivotally mounted in a frame 5 so as to be capable of a lateral swinging movement to bring the sole of the shoe indicated at 6 into the desired position with relation to the leveling roll which is being used. The frame 5 is pivoted upon rovided with a segmental rack 7 with which a worm'B meshes, and bymeans ofwhich the frame 5 is oscillated to cause the sole of the is being used in contact with the sole of the reciprocating slide hereinafter referred to, to whlch a rapid vibrating movement is imparted from the shaft 12 by means of a crank disk 17, a link 18 connecting the crank disk to the lower end of an arm 19 secured upon a rock shaft 20, slotted arms 21 secured to the rock shaft, blocks 22 adjustably mounted in the slotted arms, and links 23 connecting the blocks to the reciprocating slide.

The mechanism so far described, and all other parts not hereinafter specifically referred to, are constructed and arranged to operate in the same manner as the corresponding mechanism and parts of the machine disclosed in the patent to Gilmore No. 344,650, to which patent reference may be had for a full disclosure thereof.

In the specific embodiment of the present invention illustrated in the drawings, three leveling rolls are provided indicatedat 24, 25 and 26, and these leveling rolls are all secured to a shaft 27 so as to rotate there- .with. The shaft 27 is journaled at its ends in downwardly. extendin portions of a carrier 28 which is mounted in the reciprocating slide 29 so as to be capable of adjustment laterally with relation to the shoe supporting ack, the object of this adjustment being .to enable any one of the three leveling rolls rier 28.

To cause the leveling roll which is in cooperative relation with the aek to exert alternately a rubbing and a rolling action upon the sole of the shoe, a ratchet wheel 31 is secured to one endof the shaft 27, as best shown in Fig. 4, and a pawl 32 is pivotally mounted upon the frame 28 and arranged to engage the teeth of the ratchet wheel. The shaft 27 is thus allowed to rotate freely on its axis during the vibrating movement of the leveling roll in one direction and is held from rotation during the movement of the levelin roll in the opposite direction, and the rol l is caused to alternately roll and rub .the sole. As illustrated in the drawings, the ratchet wheel 31 and the pawl 32 The carrier 28 is provided with are soarranged that while the roll is moving toward the heel end of the sole it is allowed to rotate on its axis, and while the roll is moving towa '1 the toe end -of thesole it is held fromrotation so that the rubbing action is exerted in a direction extending from the heel end of the sole towardthe-toe end of the sole. The advantages secured by so ac- .tuating the roll have-been hereinbefore stated.

It is sometimes desirable to preventthe rotation of the leveling roll while the roll is movingin'both directions to cause the roll to rub the sole without exerting any rolling ac tion thereon. .To this end in the construction illustrated in the drawings a ratchet wheel 33 is provided upon the other end of the. shaft 27 and a pawl 34 is pivoted to the f-frame28 and arranged so that it mav be swung into engagement ,with 'the ratchet wheel. Normally the pawl 34'is swung out of engagement with the ratchet wheel 33 as indicated in Fig. 3, so that the leveling roll isjfree to rotate during its vibrating movement in one direction. When, however, the pawl is-swung mto engagement with the I ratchet wheel, the rotation of the roll durin its movement in one direction LS prevente and if the pawl 32 is in engagement with the ratchet 31 the rotation of the roll is pre vented during the vibrating movement ofv the roll in both directions. By swinging the pawl into engagement with the ratchet 33 and swinging pawl 32 out of en agement with the ratchet 31, the leveling rofi may be. caused to exert a rubbing action on the sole during-its vibrating movement toward the heel end of the sole if desired.

As illustrated in Fig. 2', three leveling rolls are 1provided, the roll 24: being of comparative y small diameter and cylindrical in .shape, the roll 25 being concave longitudinally, and the roll 26"being conical. It is preferred to use these three sha es of rolls,

;as by their use a great many di erent styles of shoes can be leveled in a'satisfactory'manner, the roll 25 being used on ordinary styles, the roll 24beingused on shoes having high arches, and the roll 26 being used on shoes having excessive swing;

It is often necessary or, desirable to substitute a roll of a difierent size or shape for one of the leveling rolls,ito suitthe particular style of'work being operated upon. As illustrated a e in Figs. 5 and 6, theroll 25 is constructed so i that an interchange of rolls may be made easily ainduuickly. As illustrated, theroli 25 isdivided longitudinally into two sections, so that the sections are'removablefrom the machine directions extending radially :of the roll. The-two sections ureprovided at their ends with/projections 35 which are engaged byclam ing'nuts36 threaded u on the-shaft 27,1 anil ,by means, of which -vention having been indicated, and a machine embodying the various features thereof in their preferredform having been specifically described, what is'claimed is:-'
