This invention relates to means to be mounted on the turret head of a turning lathe in vorder that va plurality of diameters may be turned in oneposition of the head and the remaining positions of the head be utilized for furthervoperations. The usual turret head is provided with six vertical or horizontal faces onwhichvarious tools may be secured to have the individual tool come into position for the cutting operation as desired upon the rotation of the head from one positionto the other. By employing my structure herein described, one of these positions on the head is employed, only for the mounting of the structure thereon and the remaining faces on the head can carry additional tools as usual. The primary purpose of my invention is to permit the tooling up of the head for operations in number exceeding the number of faces carried by the head.

In the form of vmy structure herein shown and described eight different diameters may be turned with one setting of the turret head Vand additional diameters may be turned by revolvingvthe head as usual to bring other tools into position as may besecured on the additio-nal faces thereon. For example, supposing the head to have the usual six faces, a maximum of thirteen operations may be performed with one complete set up of the turret head, my structure increasing the number of operations from six to thirteen. I have ytermed my invention a rolling turner and the natureof it willbecome apparent in the following description with reference being made to the accompanying drawings, in which y y Fig. 1` is afragmentary front elevation of a structure embodying my invention;

I cutting 28 which I form a vertically aligned plate 10 from the lower rear side of which `horizontally extends a mounting bracket 11. The plate 10 1s provided with a hole 12 through which the stock 13V to be operated up'on may be '55 passed. Y A tool carrier 14 is rockably secured against the front face ofthe plate 10 by means of the bolt 15 passing through the block to abut the front face of the plate by "a shoulder and extend on through the plate by a reduced diameter to have a nut 16 screwthreadedly engage the bolt from the rear side of the plate. The block 14 is provided with a hole therethrough to carry the cutting tool 17 and set screws 18 are provided to hold the 65 tool in the desired position. A plate 19 extends upwardly, from the block 14 in sliding contact with the front face of the plate 10 and has its upper end beveled to pass slidingly under the head of the bolt 20 which l0 passes through the plate 10 and carries the adjusting nut 21 on its rear end. The underside of' the head of the bolt 20 is beveled, Fig. 4, to correspond with thebevel on the end of the plate 19f so that by drawing the bolt 20 through the pla-te 10, the beveled underside of the bolt Vhead will draw the plate 19 back against the plate 10. By thus guiding the upper end of the plate 19, the Y tool 17 is prevented from moving laterally in reference to the plate 10.

Immediately above the carrier or block 14 and carried by the plate 19 is an upwardly turned ear 22 and a pin 23 is passed through this ear and into the plate 19 to roclzably carry a cam 24 thereon. A handle 25 is fixed tothe cam as a means of revolving the'cam about the supporting pin. In referring above to the carrier or block 14 and the plate 19, it will be understood, upon referring to the drawings, that the block 14 is an integral part of and extends forwardly from the plate 19. To the Vright and somewhat above the hole 12. the plate 10 is provided with another opening 26 here'shown as being substantially rectangular in shape. A cylinder 27 is revolubly mounted in this opening 26 on a screw is entered through the right end of the plate 10 and passed revolubly through the cylinder 27 and screwthreadedly engaged 100 in the end of a post 29. The post 29 is an integral part of the plate 10 and extends from the left side of the opening 26 toward the right along the longitudinal center line of the opening to abut the left hand end of the cylinder' 27. On the left hand face of the cylinder 27 are located a plurality of posts 30, each of which screwthrcadedly enters the cylinder 27 with its axis parallel to the axis of cylinder 27. The number of these posts 30 is here shown as eight equally spaced around the end of the cylinder. rIhe outer ends of these posts are rounded and have a hexagonal head adjacent the rounded end as a means of turning the posts in the cylinder 27. In order to retain the posts in any position of 'the heads thereof inrelation to the distance from the end of the cylinder, collars 31 are provided, one on each post screwthreadedly engaging it' and adapted to be turned up against the face of the cylinder as a lock nut.

The posts 30 are positioned around the face or end of the cylinder 27 to have their heads revolve in the path of the face of the cam 24 so that the degree of rotation of the tool carrier 14 to the right may be limited by the cam 24 striking against and bearing on the heads ofy these posts. In other words, by adjrsting the lengths of each of the posts 30 which extend from the cylinder 27 the point of the 'tool 17 may be thus located to cut predetermined diameters by allowing the cam 24 `to bear selectively against the end of that Vpost corresponding to the diameter desired to be cut. By raising the handle 25 and swinging it around to the right, the cam 24 is correspondingly rocked to permit the tool 17 to rock to the right away from the stock 13 so that the stock may be shifted longitudinally or the cylinder 27 revolved without the tool striking the uncut part of the stock 13 or the ends of the posts 30 striking the cam as they may be revolved to a new position. In order that there may be no lateral rocking of the cylinder 27, I provide the post 32 to extend laterally from the front face `of the plate 10 and around into sliding contact with the outer end of the cylinder 27 in direct line with that post 30 which is in contact with the cam 24.

Referring now to the left end of the plate 10, an integral extension is provided which comprises essentially a horseshoe shaped frame 33 having the top and bottom legs 34 and 35 respectively. The opposing inner faces of these legs are slotted centrally of their lengths to slidingly receive and carry a block 36 whereby the block may be shifted 6oalong the slotstoward and away from the hole V12. The extension 33 is parallel to but mounted somewhat forwardly from the front vface of the plate 10. A screw shaft 37 screwthreadedly engages through the block 36 and vextends rockably through the vertical connecting member between the outer ends of the lees 34 and 35 whereby revolving of the screw 37 will move the block 36 longitudinally of the slots in the two legs. Toward the inner ends of the legs 34 and 35, the slots 38 and 39 therein are cut back into the legs arcuately to receive therein the tongues of the roller carriers 39 and 40 which are revolubly carried on the center bolt 41 extending transversely back through the plate 10 and secured by the nut 42. Rollers 43 and 44 are revolubly mounted in the right hand ends of these carriers 39 and 40 respectively and adjustable screws 45 and 46 are carried to extend from the right hand face of the block 36 to bear against the left hand sides of the carriers 39 and 40 as the block 36 may be advanced thereagainst. Connecting links 47 and 48 loosely tie the carriers 39 and 40 to the block 36 as means for rocking the carriers backwardly to increase the distance between the rollers 43 and 44 as the block 36 may be shifted to the left. The links 47, 48 merely serve as means to retract the rollers 43 and 44 from the center of the hole 12, and accurate distances between the rollers are maintained by the adjustments of the screws 45 and 46 against which the carriers compressively bear when the stock 13 is pressed against the rollers 43, 44 during the cutting operation.

Now to coordinate the locating of the rollers 43 and 44 in relation to the diameter' of the stock 13 with a given cut to be taken therevon as determined by the location of the cyl- 'a screw 51 through a horizontally disposed post 52 carried on the lower end of a downturned arm 53 revolubly through the cylinder 50 and screwthreadedly into the metal therebehind which connects the innermost ends of the legs 34 and 35 with the plate 10. A plurality of posts 54, eight in number to correspond with the number of posts on the cylinder 27, screwthreadedly engage the cylinder 50 from its left hand vertical face and are spaced equidistant therearound on the circumference of a circle so that the ends of the posts may be consecutively engaged by a back turned finger 55 extending from the block 36. By suitably adjusting these posts 54 to have the required lengths extending from the cylinder 50, the block 36 is intercepted in its travel toward the tool 17 to limit the amount of movement of the carriers 39, 40 thereby and consequently the distance between the rollers 43 and 44.

In order that the block 36 may always be stopped with the same degree of pressure of the finger 55 against a post 54, I provide a ratchet mechanism on the outer end of the screw shaft 37 which consists essentially of a lOl) hand wheel 56 revolublyV fixed. to the end of the shaft 37 and having a hub with notches or teeth thereon adapted to be engaged by teeth projecting theretoward on a collar 57 which is keyed to the shaft 37 to revolve therewith but sliding longitudinally therealong, and a compression spring 58 urging the collar 57 toward the hub of the wheel 56. By turning the hand wheel 56, the block 36 may be advanced longitudinally. alongthe legs 34 and 35 since the collar'57 is in engagement with the wheel through the interengaging teeth and upon the finger 55 striking the end of a post 54, continued rotation of the wheel 56 may be had but only by the collar 57 moving against the spring 58 to permit the teeth to slip over each other so `that the strength of the spring 58 will control the amount of pressure'by which the finger 55 will bear against any postA 54. Y

In order that the cylindersV 27 Vand 50 may be revolved in the proper sequence so that the rollers 43, 44 are set to receive'proposed diameters of the stock 13 therebetween for the cut to be made by the tool 17, I provide means for simultaneously revolving the cylinders in unison. The cylinder 27 is provided with an annular gear 59 and a horizontally disposed shaft 60 is revolubly carried between the ears 6l and 62, Fig. 5, on the rear side of the plate l() to have a spur gear 63 fixed thereon in constant mesh with the gear 59. A knurled handle 64 is fixed on the outer end of this shaft 60 as a means of revolving it. Gn the opposite end of the shaft 6() is a spur gear 65 which is in constant mesh with a spur gear 66 fixed on the shaft 67 mounted thereabove and carried across over the hole l2.-` On the-other end of this shaft 67 is fa second spur 63 in constant mesh with a spur gear 69 on a shaft therebelow which entends through the bearing 7() to carry a spur gear 7l which is in constant mesh with the gear 72 formed about the cylinder 50. The intermediate shaft 67 is provided merely as a meansto go around the hole l2 in order that a free opening may be obtained s-o as to prevent any interference upon the insertion'of stock therethrough. It

is therefore to be seen that by revolving the handle 64, both cylinders 27 and 50 are simultaneously revolved in the same direction and at the same rate of speed since the gearing between gear 63 and the gear 7l is identical in speed ratio at each end of the shaft 67. Thus by adjusting the length of a post 30 on the cylinder 27 to give a desired location of the point of the tool 17 the diameter of the cut on the stock 13 is obtained and by adjusting the post on the cylinder 50 then in line to be contacted by the finger 55, the rollers 43 and 44 may be brought to the proper positions upon turning up the shaft 37 to move the block 36 and bring the finger 55 against that ost. p It sometimes happens that in cuttingstocllz,

for instance in taking the initial cut on hexagonal stock, considerable vibration is set up which might cause the rollers 43 and 44 to retract slightlyV by shaking the screw 37 to cause it to revolve. To prevent such move- Vment of the rollers, I provide set screw 73,

revolving of the shaft is prevented. I also provide means for retaining the cylinders 27 and 50 in the selected positions. Such means is here shown as including a hole 7 5 1n the circumferential wall of each cylinder at each lo- 4 cation of the posts 30 or 54 as the case may be.

In other words, there are eight holes 75 spaced equidistant around the circumference of each of the two cylinders. A pin 76 is slidingly inserted through the top side of the plate l0 and carried vertically down therethrough to drop normally by its lower end into the holes 75 as the cylinder 27 may be revolved therepast. Similarly a pin 77 is passed slidingly and vertically vdown through that partof the casting extending rearwardly from the top leg 34 to have its lower end normally drop into the holes 75 in the cylinder 50 as it may be revolved. In order to raise and lower these pins 76 and 7 7 'to permit l the turning of the cylinders, a lever 78 is pivotall 1 connected by its outer end to the end of thepin7 6, fulcrumed over the post 79 and pivotally connected to the center post 80, and likewise a lever 8l has its outer end pivotally connected to the top end of the pin 77, ful- `crumed over the post 82 and pivotally connected by its other end with the post 80. VThis post 8O has its lower end slidingly enteredY in a bore in the top 'side of the plate 10 and rests b its lower enda ainst acorn ressionis rino' Y v n 83 `so that the post 80 is normally vurged upwardly to .push the pins 76 and 77 downwardly. The pins may be lifted by pushing down on the post to overcome the spring 83 and the post 80 is thus held therein while he thumb nut 64 is being turned. Release of the post 8O allows the pins 76 and 77 to bear by their lower ends against the respective cylinders and to drop into the next appearing holes75 as the cylinders may be revolved and thereby prevent further rotation of the cylin- Adersuntil the pins are again lifted.

Vhile I have herein described and shown my invention in the best form now known to y me. it is obvious that structural changes may be made without departing from the spirit of the invention and I, therefore, do not desire to be limited to that precise `form beyond the limitations as'may be imposed by the following claims. y
