, Patented Dec. 8, 1914..

Application filed August 9, 1911. Serial No. 643,247.

To all whom it may concern:

Be it known that I, Fern M/Coousun, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Skiving- Machines; and Ido hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

My present invention relates to improve ments in skiving machines, being adapted for use in connection with the skiving of any character of work, and it has for its object to pro'videa novel construction and arrangement of parts whereby the work will not be interfered with by the mechanism as it is fed through the machine, and after it is acted upon by the cutter.

A further object of my invention is the provision of a feed disk which may be adjusted in its cooperative relation to the feeding roll and cutter.

Still another object of the invention is to provide a work guide, having a novel means for adjusting its position relatively to the feeding roll.

To these and other ends the invention consists in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings: Figure 1 is a view in front elevation of a machine, disclosing one embodiment of the invention; Fig. 2 is a view in end elevation of the same; Fig. 3 is a view in elevation from the opposite end; Fig. dis a sectional view on the line a:-zv of Fig. 2, the feed disk and its supporting bracket being removed; Fig. 5 is a sectional view on the line 7 -7 of Fig.4; Fig.0 is a view in elevation of the feeding roll and transmitting mechanism therefor; Fig. 7 is a top plan view of the machine; Fig. 8 is a sectional View on the line a-a of Fig. 7, and Fig. 9 is a sectional view on the line b-?) of Fig. 4.

Similar reference numerals throughout the several figures indicate the same parts.

In the present construction and arrangement of parts, wherein I have shown a preferred embodiment of the invention, the machine comprises a base 1, on which is mounted the operating mechanism, the base being suitably supported on the frame Slid: ably arranged upon the base 1 is the stand ard 3 which is movable between the guides 4, and held in adjustedposition by means of the adjustingscrew 5. The standard 3 is provided at its upper portion with a forwardly extending arm 6 provided at its front end with the bifurcations 7 between which is pivotally arranged the plate 8, provided with upper and lower bearings 9 and 10, respectively, holding the threaded sleeve 11. within which is rotatably mounted a shaft 12 which carries the cutter 13 and is provided with a suitable pulley 14L arranged intermediate the bearings 9 and 10. The cutter 13 preferably occupies the position shown in Fig. 1, being angularly disposed relatively to its cooperating parts, such angular adjustment being susceptible of change in a manner that will be presently explained, and vertical adjustment of the cutter being secured through movement of the threaded sleeve 11 with relation to the bearing 9. The plate 8 is provided at its rear end with a toothed segmental edge 15 arranged to be engaged by the screw 16 a mounted on the arm 6 and operatedbythe thumb nut 17. a H

Suitably attached to the bearings 9 and 10 is the bracket 18 which is provided with bearings 19 and 20, the latter having journaled therein the shaft 21 which carries the grinding disk 22 and rotates within a sleeve 23 having threaded engagement with the bearing 19, so as to obtain vertical adjust ment of the grinding disk relatively to the cutter. The shaft 21 carries a suitable pulley 2 by which the grinding disk may be operated in a manner that will be presently made clear. a

In order to obtain proper cooperation between the cutter, feeding roll, and the feed 1 disk, and centering of these parts, it is desirable to provide some means for obtaining lateral adjustment of the feed disk relatively to the cutter and feeding roll, as, for instance, to allow for wearing away of the cutter, and to this endqin the present em bodiment, the feed disk, designated at 25, is carried by the shaft 26 which is rotatably mounted in bearings 27 formed on the bracket arm 28, the latter being pivoted at 29 to the carrier 30 which is provided with suitable Ways having engagement with the guides 31 arranged on one of the bifurcations 7, as shown in Fig. 9. By this an rangement, the feed disk may be swung laterally on the pivots 29 to effect its proper positioning, while at the same time, longitudinal movement of the standard is possible relatively to the feed disk by means of the sliding engagement of the carrier30 With the guides 31. To hold the feed disk in its position of lateral adjustment, an ad-' justing screw 32 is provided for engagement with the bracket arm 28 which is held relatively to said screw by means of the thumb nuts 33. The shaft 26 carrying the feed disk is provided at its upper end with a pulley 34 by which the shaft is rotated as will be hereinafter described, the feed disk being suitably held in normal lowered position by means of the spring 35 arranged between the upper bearing 27 and the collar 36 fixed upon the shaft 26.

In order to effect the proper feeding of the work beneath the feed disk to the cutter, there is provided in the present embodi ment the feeding roll 37, which is journaled upon the bearing 38, the latter being carried by the post 39, having the base 40 slidably arranged in the track 41 on the base, and held in the desired position of adjustment by the adjusting screw 42'. Lateral movement of the post may be effected in any suitable manner, as by means of the adjusting member 43 which is rotatably mounted on the post 39 and has threaded engagement with the stationary abutment 44.

The feeding roll 37 is provided with a l-iorizontal surface positioned beneath the feed disk 25, a shoulder 45 adjacent to the horizontal surface, and a beveled surface extending beyond said shoulder to the opposite side of the feeding roll. Arranged for cooperative engagement with said beveled portion is the guide 46 Which is carried by the arm 47, the latter being formed integral with the sleeve 48 which is arranged upon a support 49, the latter being suitably attached to the post 39 and arranged parallel to the normal plane of the cutter 13. The sleeve 48 is held in adjusted position on its support 49 by means of the adjusting screw '50, or in any other suitable manner. The guide 46, as will be noted from Fig. 1, is arranged to engage the edge of the work, and is provided with an upwardly and for wardly extending box or housing 51 within which is arranged a suitable presser foot 52, held in engagement with the work by means of a spring 53'. The presser foot 52 is provided with the recess 54 withw'hich cooperates the thumb screw 55 for obtaining necessary vertical adjustment; The spring 53 is held in operative position by means of the thumb screw 56.

The feeding r011 may be rotated from beneath the base of the machine in any suitable manner, this being effected in the present embodiment. by means of the shaft 57 arranged beneath the base 1 and carrying the sprocket wheel 58, the feeding roll being provided with a corresponding sprocket wheel 59, and a suitable chain 60 connecting the respective sprockets.

Journaled upon the standard 3 is the vertically arranged shaft 61 carrying the pulley 62 at its upper end, the beveled gear 63 r shaft 66 also carries the pulley 68 and friction cone 69, the latter being arranged for engagement with the friction clutch 70 which is formed integral with the pulley 71 and is loosely slidable along the shaft 66', such movement of the clutch being effected by vertical movement of the cam lever 72 which engages the stationary cam 73, and carries a vertically extending post'74 at its upper end for a purpose to be explained hereinafter. Pulleys 75 are arranged on opposite sides of the standard 3, being carried on the vertically adjustable supports 76, and the cutter is driven by means of the cable 77 which leads from the pulley 68, around pulleys 75, to pulley 14, on the shaft 12, as shown clearly in Figs. 1 and 7. The pulley 71 is rotated by a cable 78 leading from a suitable source of power, and motion is transmitted to the. several parts of the machine from the pulley 71 by moving the friction clutch 7 0 into engagement with the friction cone 69,'this being effected by operation of the cam lever 72 downwardly. When the cam lever is operated in the reverse direction, to effect the release of the parts, it is desirable that some meansbe present for stopping the machine immediately, and to this end, 1 provide a pivoted brake shoe 7 9 arranged for engagement with the pulley 68, as shown clearly in Fig. 1, and having a tail-piece 80 which is adapted to be engaged by the post 74 on the cam lever, when the latter is moved upwardly.

The feed disk 25 is preferably rotated by means of the cable 81 whichleads from 1511i ley 62 to pulley 34, mounted, respectively, on shafts 61 and 26. In order to allow for taking up of any slack in the cable 81 resulting from the longitudinal adjustment of the standard 3, I provide the pulley 82 mounted on the adjustable arm 83 and arranged to engage the cable 81, as shown in Fig, 7.

The grinding disk may be rotated in any convenient manner, and in the present embodiment, to this end, I provide a clutch face 84: on one of the pulleys 75, which is arranged to cooperate with the pulley 85 arranged on the same bearing, the latter pulley having the friction cone 86 for engagement with the clutch face 8-l-. Asuitable cable 87 leads from thevpulley 85 to the pulley Q-l hereinbefore described, to effect rotation of the grinding disk which is normally idle, when pulleys 7 5 and 85 are disengaged. Movement of the pulley 85 to clutch the parts together may be effected in any desirable manner, as in the present embodiment, by means of the lever 88 which carries a block 89 arranged to engage the spindle 90, the latter being hollow and mounted upon the bearing 91 which supports the pulley 75, the pulley 85 being fixed on the hollow spindle 90, which is held normally away from the bearing 91 a by means of the spring 92.

By the arrangement of the parts as herein shown and described, it will be noted that a free area is afforded surrounding the feed ing roll, and the operating point, this being particularly desirable where the machine is operating on a curved or rounded piece of work which turns continuously as it is fed, and comes in contact with the frame work or operating mechanism of the machine, unless such a free area is provided as in the present invention, and while I have described the structure as embodying a standard in spaced relation to the feeding roll, and provided with an arm extending above and toward the feeding roll and carrying the feed disk and cutter, it is to be understood that the same end may be accomplished in other ways without departing from the spirit and scope of this application.

A further important feature of my improvements resides in the provision of means for securinglateral adjustment of the rotating feed disk by which the feed disk, and cutter may be properly centered with relation to the feeding roll and the work, under all conditions, and regardless of the size of the cutter.

My invention is further chm'acterized by an improved form of work guide, the essential feature of which consists in enabling its adjustment, with relation to the work, in the direction of the plane of the cutter, and the invention is not to be limited to the particular means herein shown for accomplishing this purpose, but contemplates any form of guide that is capable of adjust ment, in a direction parallel to the plane of the cutting member.
