Specification of Letters Patent.

Patented Dec. 6, 1921.

Application filed November 12, 1917. Serial No. 201,521.

To all 10720712275 may concern Be it known that I, OTIS R. ANenLL, a citizen of the United States, residing at Haverhill, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Edge Setters and Burnishers, of which the following is a specification, reference being had therein to the accompanying drawings. 7

This invention relates to machines for setting and burnishing theedges of shoe soles and. more particularly to means for supporting and for reciprocating the operating tool.

In machines of the above type as at present constructed and in which cranks 01'' eecentrics have been employed for reciprocating the tools, much annoyance has been caused by reason of the excessive vibration produced, resulting in disagreeable noise and rapid wear of parts. It is an object of the present invention to so construct a machine of the above type as to eliminate all unnecessary machine parts and at the same time to reduce undesirable vibration to a minimum.

It is a further object of the invention to provide in an edge setting machine a tool holder constructed to simultaneously hold a plurality of tools and adapted to be sewntrolled as to present either of said tools in working position at the will of the operator.

Other and additional objects and advantages of the present invention together with desirable details of construction and improved combination of'parts will be hereinafter described and particularly pointed out in the claims.

Figure 1 isa side elevation of the operative parts of the tool supporting and operating mechanism. Fig. 2 is an end elevation of the same, and Fig. 3 is a plan view looking from above. Figs. 4, 5 and 6 are corresponding views of a second and preferred form of the invention. Fig. 7 is a diagrammatic elevational view showing the operative mechanism as mounted in position on the machine frame, and Fig. 8 is a detail thereof.

1 is a hollow shaft mounted in suitable bearings and continuously driven from any convenient source of power, as by means of a pulley 1*. Within said hollow shaft and carried thereby is a relatively fixed rod or supporting-member 2. This rod may be held in fixed position with respect. to the frame of the machine by any suitable means, but is herein shown as provided upon its rearward extremity with a gear 3, which gear is arranged to mesh with asecondary gear or. rack 23* (Fig. 7') adapted to be turned manna ally and to be fixed in either of two adjusted positions for a purpose which will be hereinafter described. The forward end of said rod 2 is provided integrally or otherwise with an enlargement 4, such enlargement being slotted or bifurcated at its outer extremity to provide opposed arms 5 and 6. Passing through suitably formed openings in said arms is a stub shaft or pintle pm 7 said pin being provided with an en larged head at one extremity and being screw-threaded at its opposite extremity for reception of a lock nut 8.- Pivotally supported upon said shaft or pin 7 is a rockable tool-holding head 9 adapted to vibrate in a vertical plane passing through the center of shaft 2. This tool-holdinghead 9 is provided with a pair of oppositely extending posts 110, and 11, said posts being provided with suitably formed extremities l2 and 13 for the reception of tool holders of the type usually employed in machines of this character. Projecting from the posts 10 and 11, and in the plane of vibration of said head are a pair of bracket arms 14 and 15, said arms being spaced from the main portion of the head 9 to form openings 16 and 17 therebetween. Fixed in alined open? ings in said brackets and in the head and extending across said openings are a pair of fixed pins 18 and 19, said pins forming the axes of rollers 20 and 21, the rollers herein disclosed having the form of oblate spheroids, this specific form of roller, however, not being essential as rollers" of any other suitable and desired form may be substituted therefor.

.Fixed upon the end of the shaft 1 to rotate therewith is a disk-member 22, said disk-member being provided upon its face with a groove or run-way 28. This groove or run-way, as may be seen from inspection of Fig. 3, is deeper at the part 25 than at the part 245 which is diametrically opposite the same, the groove as thus described forming in effect a face-cam of varying depth.

The support 4 is so located with respect to the shaft 1 and disk 22 that the rollers 20 and 21 engage with the bottom of the by reason of the travel of the rollers '20 and 21 over the high and low parts of the cam groove 23, the head 4 carrying said rollers and the tool-holding posts carried thereby will be rapidly vibrated in a plane parallel to the axis of the shaft 1.

Byreason of the fact that the operative partsinthismachine are all'loca'ted closely adjacent the bearings and that no long or heavy lever-members are necessary for securing the desired movement of the toolcarrying parts, very little vibration in the machine frame with its consequent noise and wear isproduced, the machine as above con structed being almost noiseless in its operation,while at the same time performing its work well and efficiently.

The machine herein disclosed as above described is provided with oppositely extendingtool-carrying posts, and by reason of the arrangement described, embodying the gear 3 with means for turning the same and lockingit in position, the relative arrangement of the posts 10 and 11 may be reversed, thereby permitting the use, as is common in machines of this general charac ter, ofseparate tools for operating upon the shank and forepart of the shoe sole, the gear 3 and the described connections permitting reversal of the head as oftenas may be desired.

As an example of means for turning and locking the supporting-member 2 reference may be had to F 7, wherein is shown a gear segment 3 fixed to a shaft 50e21tending through the frame and having a hand lever 51 upon its forward end, suchlever being provided with a locking pin 52 adapted to engage either of a pair of suitably formed sockets 54: in the frame, whereby the lever 51 together with gear segment 3 may be locked'at will in either of the two desired positlons. While the locklng means the closed is well adapted for use inthe present machine, it is to be understood that the invention is not limited thereto as any other and equlvalent mechanism may be substituted therefor. In the modification shown in Figs. 4, 5 and 6 many of the parts cor upon the same; a the forked or bifurcated head carried upon said supportgo and G the oppositely disposed a ms of said forkedmember; the pintle pin or shaft and 8 the lockingnut for the same.

Mounted to rock upon said pintle pin is the vibrating tool-holding head 9*, said head havingextending therefrom in opposite directionsthe tool-carrying posts lO 'and 11. Upon the posts 10 and 11 is pivoted to escillate in a horizontal plane a disk or yoke memoer 30, said yoke-member being provided with arms 31 and 32 having journal openings 31, 32 therein adapted for pivotal mounting upon the posts. 10 and 11. The yoke-member 30 has formed upon its rearward face a groove 33 forming one element of a ball-race. Fixed upon the shaft 1 is a disk 22 having formed therein a groove 34', said groove forming the complemental ball-race element, the disk 22 being also provided with a flange 35 inclosing the circular ing said ball-race 33. Inspection of Fig. (i will show that the ball-race 3a is deeper at the part 25 than at the part 524:, thus forming in effect a cam groove in the face of said disk. Between the ball-race elements 34: and is mounted a: continuous series of ball bearings 36, said bearings serving to transmit motion from the rotating disk22 to the yoke-member 30. r

Upon rotation of the shaft 1 the race element Sd is rotated, causing the bearings held in the same to travel with relationto therespective race elements 34 and 33, and by reason of the inclined arrangement of the raceelement 34, such rotation will cause a rocking movement of the yoke 30 about its pivotal support. Asthe shallow portion of the groove passesthe vertical plane, it will cause a rocking movement of yoke element 30 together with head 9* about the pintle pin 7, thus producing that movement of the tool holders necessary for the proper function of the machine. its the shallow portion of the groove, however, passes the horizontal plane, a rocking movement of yoke 30 about the posts 10 and 11 will be produced, this movement being an idle movement as far as the tools are concerned, its only function being to'prevent jamming of the ball bearings in passing along the race which action would occur in this form of the invention due to the employment of the continuous seriesof bearings unless some provision of this character were made.

It will be evident, therefore, that yoke 30 is given a Wabbling motion which may be considered as vibration in a plane which is constantlyfrotating about the. cam axis or as vibrating inan infinite number of planes while it isso held. Vhen the tool holder is rotated tolchange tools, its plane of vibraortionof the yoke-member 30 carrytion rotates similarly to that of the actuatin yoke 30.

Vhile the form shown in Figs. 4, 5 and 6 is a preferred form of the invention, it is to be understood that the invention is not to be limited to the specific details of construction herein shown, but that it is to be construed as covering all modifications and variations of the same within the province of mechanical skill, and as included in the scope of annexed claims.
