To all whom 'it may concern.' V

Be it knownthat I, EaAsTUs E. WINKLEY,

a citizen of the United States, residing at L un, in the county of Essex and State of` ssachusetts, have invented` certain. new and useful Improvements in ,Sole-Leveling Machines; and I do hereby declare the following to be a full, clear, and exact descri tion ,of the invention, such as will enabe others skilled in the art to which it appertains to make and use' the same. I

The present invention relates to sole levelmachines and particularly to machines for leveling turn shoes.

The sole of a turn shoe isithin as compared with the soles ofother kinds of shoes. and when the shoe is re-lasted after being turned, the sole is more or less wrinkled, particularly at the 4shank portion, and the stitches of the inseam form elevations upon the surface of the sole. The operation of levelin 'the sole consists in pressing the elevations ormed by the stitches of the inseam down flat, in removing the wrinkles in the solc, and in causing the sole to conform to the shape of the bottom of the last. The hand method of leveling turned shoes consists in beating out the seam and in partially removing. the wrinkles and conforming the sole to the bottom of kthe last b means of a hammer and in completing t e leveling operation .by rubbing the sole with a stick termed in the art a long stick or rub stick, until-the wrinkles are entirely removed and the entire sole is smooth and conforms to' the shape of the lst.

Vibratin roll sole leveling machines have been used or leveling turn shoes, althou h these machines are designed particularly or leveling welt shoes. The results attained by the use of these machines has, however, not been entirely satisfactory as the wrinkles are sometimes pressed into the sole instead of being removed aad.- diiliculty is experienced in completely obliterating the rojections produced by the' inseam. arious other machines have also been utilized for leveling turn shoesybu-t so far as the appli'- cant ia advised, tbe-work done by these 'machilies has been inferior to that 'produced by the hand method of leveli The object of the prese invention is to provide a machine by which the sole of a turn shoe will be acted upon in substantialy the same way as in the hand method of lev ing and by which the levelin operation can be performed easily and quic ly and as good.

- results produced as when the-leveling operation is performed by a skilled operator usingl the hand method.

A machine embodying the present invention com rises a shoe supportin jack and sole levelling mechanism relative y movable to transfer the point of `operation of the leveling mechanism over the shoe sole. In accordance with the present invention the sole leveling mechanism is constructed and arran ed. to. rogressively smooth out the sole uring the relative movement of the jack and leveling mechanism and to simultaneously deliver u n the sole a series of blows in a direction substantially., erpendicular to the surface'of the sole, so at the soleis `acted u n in substalntially the same manner as in the) hand method of leveling.

In its broader as ts the invention .contem lates the provision of any suitable form of evelin mechanism adapted to smooth out and' ammer the sole in .the manner above stated. The form of mechanism which it is preferred to use on account of its com actness and simplicity of construction an which has given satisfactory results in actual practice, comprises a' single levelin device to contact'vnth the surface of the so e and means for su porting and actuating the device to per orm both operations of smoothing out and hammering the sole. This leveling device may be of any suitable form-and any suitable mechanism for actuatin ,the device to hammer the sole may be emp oyed. 'It has been found, however, that the best results are secured when the device is actuated to impart sharp uick blows to the sole and inthe preferred orm of the invention this mode of operation is secured by the provision of a hammer arranged to deliver a series of blows in rapid succession upon the leveling device. In order that the action of the leveling device in smoothing out the sole may 'approximate as nearly as possiblethat of thehand operated ru-b stick or long stick, it is preferably constructed to exert a rubbing action upon the sole and in elect to constitute a rub\.stick. Also referably a vibrating movement back' a forth imparted to the leveling dederstood from an inspection of the accompanying drawings illustrating acmachine embodying thel same in its preferred form, which machine, in addition to the features of invention above referred to, also embodies certain novel constructions, combinations and arrangements of parts hereinafter described and claimed, the advanta esA of which will be obvious to those ski ed in the art.

Referring to the drawings, Figure 1 is a view in side elevation of a sole leveling machine embodying the various features of the present invention in their preferred form,

ig. 2 is a plan view of the mechanism for supporting and actuatin the sole leveling device, Fi 3 isa centra vertical sectional view of t e mechanism illustrated in Fig. 2, and Fig. 4 is an end view of `a portion of the mechanism illustrated in Figs. 2 and 3.

The shoe su portingv jack is indicated at 1 and is pivotally mounted at 2 in the front portion of the frame of the machine so as to be capable of anoscillating movement to move the shoe supported upon the jack backward and forward longitudinally beneath the sole leveling device. The jack is provided with a rigid heel ost 3, in the upper end of which is ivota ly mounted a last pin carrier 4 whic can be oscillated on its pivot b an actuatin screw-threaded rod 5 inl or er to clamp t elasted shoe firmly on the jack. The toe post of the jack is indicated at 6, being ivotally mounted at its lower end and provided at its upper end with vertically bed 10, the

" the cylindrical portion of the a rest 7, forthe sole leveling device and with a vertically adjustable toe sup ort '8 for the toe portion of the lasted shoe. he toe post 6 can be adjusted towards and from the heel post 3 to accommodate shoes of different sizes b means of a screw threaded adjusti r 9.

he sole leveling device is mounted in a swinging and laterally rocking front portion of which is in the form of a oke and the rear 4portion of which is cylindrical and received in a bearmounted at 12 in the upper i 11 ivotall ng P thepivrear portion o the machine frame, otal. connection of thebearing 11 to swing vertically and the enga ement of with the bearing 11 allowing the bed to rock laterally. During the epe leveling device -is pressed yieldingly against the sole of the -shoe supported on .the 'ack and the jack is oscillated and the 10 rocked laterallyl in order to isubject those of lthe leveling device. y

with. the `frame of the machine allowing the `bed 10 ration of theimachine thel leveled to the action The oscillating movements of the jack are produced by means of a hand wheel 13 fast upon a shaft 14 journaled in the frame of the machine, to which is secured a pinion 15 inehing with a segmental rack 16 upon the )ac To press the leveling device yieldingly algainst the sole of the shoe during the leveing operation a treadle and connections between the tieadle and the bed 10 are provided. The treadle is indicated at 17 and is pivotally mounted at its rear end in the lower rear ortion of the machine frame. To the trea le is pivotally 'connected a rod 18 which passes through a cross-head 19 and is provided at its upper end with an adjustab estop nut 2O etween which and the cross-head 19 a coiled spring 2L is interposed. 'xlhe cross-head 19 is connected by means of rods 22 to a cross-bar 23 pivotally mounted midway between its ends in webs connecting the arms of the yoke portion 'of the bed 10. The upper ends of the rods 22 pass loosely through thecross-bar 23 and are provided with nuts bearing u on the upper surface of the cross-bar. Be ow the crossbar 23 the rods 22 are provided with collars 24 between which and the cross-bar coiled s rings 25 are interposed. A depression of te treadle 17 4thus tends to compress the spring 21 and through the cross-head 19, rod 22 and cross-bar 23 to swing the bed 10 downwardly and yieldingly pressthe levelin device against the sole of the shoe. A ro 26 pivotally connected at its lower end at the cross-head 19 and provided at up er end with a stop nut 27 between which and a bracket 28, on the frame of the machine a coiled spring 29 is interposed' serves as a means for counterbalancing the weight of the bed 10, the treadle 17 and the connections between these parts.

The lateral 'rockin movements are imparted to the bed 10 E means 0f a lever 30 pivoted at 31 on the rame of the machine and provided with a handle 32 projecting into a position to be conveniently grasped by the o rator. At itsend the j lever 3() is vprovi ed with a pivotally mounted block 33, through which a rod 34 passes. The rod 34 is pivotally connected at its upper end 'to the bed l0 and at its lower end is provided with two collars 35 and 36 upon opposite sides of 4the block 33, coiled springs 37 being inter sed betwcenthe collars and the block which absorb the vibrations of the bed 10 and revent them from-being transmitted to the liandle 32. n In order to enable the bed 1D to be rocked easily and te be securelyheld in position the lever 30 is provided with counterbalancing weights 38 and 39.

The parts so far described and also the mechanism hereinafter described. for :im-`

parting .vibrating movements longitudinally come of the shoe sole to V'the leveling device lare constructed and arranged in substantially the same manner as the corresponding parts and mechanism of 'a welllmown vibrating roll sole leveling machine, several forms of which are disclosed in the patents to Washbum Nos. 435,882 and 435,833, Sept. e, 1890, and No. 561,035, May 26, 1896, to which patents reference is made for a complete disclosure thereof. In applying the present invention to this machine a leveling device supported in the bed 10 has been, provided and means for actuating the leveling device to smooth out the sole of a shoe supported on the jack and simultaneousl bo hammer the sole with a series of blows livered in a direction substantially ipendicular to the surface of the sole. e levelin device is indicated at 40 and is so shaped iat during the relative movements of the leveling device 'and jack it smooths out the sole in the same manner asa rub in the hands of an operator and in e'ect constitutes an automatically actuated rub 'The rub stick is pivotally mounted at its ends in bearings projected downward from blocks 41 mounted to reciprocate in guide-ways formed in the 'arms of the yoke portion of `the bed 10. To the blocks 414 vare `iyotally connected the arms of a cross-head 42 mounted upon 'the liorward end of a reciprocating rod 3. This rod passes through a slot in an upwardly projecting portion of a bracket 44 secured to 'the rear end of the o'tally connected at its rear 'end to an arm 45. The arm -45 is pivotally mounted in a l lever 4'6 'pivotally mounted on the upper rear i portion of the machine fra-me and connected i by a rod 4'7 to an eccentric strap sunoundf ing an eccentric on the drivingshaft 48. Q During the operation 'of 'the machine the shaft 48 is constantly rotated and through t the connections above described imparts a rapid vibratory movement to the rub stickf longitudinal ol" the shoe solo, the pivotal connection of the arm 45 with the lever 46 permitting the bed 10 to be rocked laterally with the vibrating without interfering movements `of the rub stick.

The means illustrated in the. drawings for i actu-ating the nib stick to hammer the sole by the hammer.

end with an adjusting nut 59, between engaged by eccentrics 53 upon a shaft 54. The shaft 54l is mounted in 'bearings in the forward ends of arms 55 pivotally mounted at their rear ends upon the cross-head 51'. A belt'pulley 56l is secured to the shaft 54, over which ebelt 57 passes by means of which the shaft 54 is rotated at a high rate of speed. The eccentrics -53 on the shaft 54 act, through the rods 52, to impart rapid reciprocating movements to the hammer 13 and cause the hammer to deliver a series of blows in rapid succession upon the rub stick 40, the blows being transmitted by the rub stick to the sn'face of the sole in a direction substantially perpendicular to the surface of the sole. The bearings for the rub stick are slightly elongated in a vertical direction in order to allow the rub stick to move Verticallv under the force of the blows imparted To rovide means for varyi the force of thebl ows delivered upon the e a rod 58 projects upwardly from the cross-head 42 through a cross-bar conneing the levers 55 and 1s providedat its u r ich and the cross-bar a sleeve 60 is inte osed. The position of the shaft 54 with relation to the rub stick is thus determined by the sleeve 60 and nut l59, `and by 'adjustin the sleeve and nut on the rod 58 the sha 54 can be moved towards and from the rub stick so as to vary the force of the blow delivered by the hammer upon the rub stick and the distance to which the rub stick is depressed. The belt 57, by which the belt pulley 56 on the shaft 54 is driven, passes over an idler pulley 61 mounted on a shaft connecting the 'levers 55, over two idler pulleys 62 mounted in the upper ends of arms 63 pivotally connected at theirlower ends. to the bracket 44 and around la pulley 64 mounted in lthe rear portion of the bracket 44. The pulley 64 is driven from any suitable source by means of y a belt 65 passing over the pulley. It will 'be apparent that the hammer 49 and shaft 54 are supported so as to be vibrated with the rod 43 and 'that consequently the hammer always remains directly above the rub st-ic: in a position to Contact with the rub stick 1 duringeacliof its downward movements. In

order lto `allow the shaftl to be so vilna'ted and 'atY the same 'time niaintain'the desired tension upon 'the belt 57 the arms 63 upon which the idler pulleys 62 are mounted are pivotally connected to sleeves 66 and rods '67 are provided pivot-ally connected at their forward ends with `thecross-head 51 Aand having a sliding engagement withthe sleeves (56 at their rear ends, each rod "67 being .ch

vided with a fixed coll-ar 68 between` w and a Sleeve ce Mailed spring sais posed. Aaxis of purl-ley 64, by which' the belt 57 is'drix'cm'islocabed in -almexnelrt with the axisabout which thehed 10 duringthe lateral rocking movements of the bed.` ",Theiidler pulleys over which the belt 57 passes and the pulley 56 on the shaft 54 areqall sup orted so as to move with the bed during its ateral rocking and vertical swing- `ingpmovements and consequentl these movements of the bed do not inter ere with the operation of the mechanism for actuating the hammer.

The rub stick is provided with a working surface curved slightly in the direction of the longitudinal axis of the shoe and also curved transversely of the shoe to fit approximately the curvature of the sole at the fore-part of the shoe. In order to allow the rub stick to automatically` accommodate itself to the longitudinal curvature of the shoe sole so that its working surface may have the same position with relation to the surface of the sole of the shoe during the entire leveling operation the working surface of the rub stick is arranged in line with or slightly above the pivotal axis of the rub stick. The upper surface of the rub stick is curved to form a ortion of a cylindrical surface, the center of) which is the pivotal axis of the rub stick. The oscillating movements of the rub i stick in accommodatlng itself vto the variationin the longitudinal curvature ofthe shoe .sole do not, therefore, displace the upper surface of the rub stick with relation to the hammer, so that the rub stick is always depressed to the same extent by the hammer at all portions of the sole.
