UNITED STATES JOHN P. BROPHY, OF CLEVELAND HEIGHTS, OHIO.

AUTOMATIC MACHINE.

Specification of Letters Patent. Patented J 11119 15,1920. A

Application filed December 6, 1917. Serial No. 205,732.

To all whom 2'2. may concern:

Be it known that I, JOHN. P. BROPHY, a citizen of the United States, and a resident of Cleveland Heights, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Automatic Machines, of which the following is a specification, the principle of the invention being herein explained, and the best mode in which I have contemplated applying that principle so as to distinguish it from other inventions.

The present invention relates to improvements in automatic machines, and moreparticularly to improvements in'the means for supporting and feeding the cutting forming tools, which are held in the turret head or tool slide, up to and away from the work.

In the usual form of automatic machines it is customary to employ a single turret head in which the tools are supported, whereas in my improved form of turret head I employ a plurality of independent heads or supports for thetools thereby enabling me to perform more and varied operations on the article being operated on, and, in this way increasing the usefulness and efliciency of the machine.

My improvement furthermore relates to an efficient and simple means for accomplishing the relative movement of the two turret heads to and away from the work.

To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed. drawings and the following description set forth in detail certain mechclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawing Figure 1 is a vertical section through the turret head of an automatic machine showing my improved operating means forfeeding the tool supports.

Fig. 2 is a partial end view of an automatic machine, part of the machine being broken away to more clearly illustrate my device. I

Fig. 3 is a front view of the tool turret showing a number of tools in position and and Flg. 4 is an elevation of the tool turret with the lathe frame in section.

The general character of my improvement may best beseen in Fig. 1' in whichfis shown a housing. adjustably mounted on the guides- 2 of 'the lathe bed 3 of an automatic machine.

In one end of thefhousing 1 is slidably mounted a cylindrical member 4, constitut-- ingone of the tool slides which is held against rotation in the housing 1 by a key 5.

Disposed parallel to the axis of the member.

4 and equidistant from the center thereof are holes 6 adapted to retain thetools for oper ating on the articles to be formed. I have shown four holes for tools in the member 4 but it 1s immaterial how many holes are provided as long as they correspond to the number of live spindles in the lathe head. The holes 6 in the member 4 are so placed as to aline with the spindles in the head when the spindle heads are in operative pos1t1on. A cylindrical recess 7 is provided in the rear of the member 4 in which a driv- I ing member 8 is adapted to fit. A spiral channel or groove 9 is cut on the drivingmember 8 in which a roller 10 is adapted to track. the roller 10 is retained in the member 4 by a stud screw 11 passing through the rear of the member 4 and acting as a bearing for the roller 10. By this means any rotation of the driving member 8 will tend to force the member 4' either forward or backward, depending on the direction of rotation' of the driving member 8. A thrust.

bearing 12 is provided in the upright. support 13 of the housing *1.

Passing axially'through the member 4 is a hollow shaft 14 held against rotation in the anism embodying the invention, such dismember 4 by means of a key 15. Mounted on the outer end of theshaft 14 are slides or guide ways 16 on which are to be mounted various tools 17 adapted to the work they which a roller 21 is guided. -A stud 22 fas tened to the shaft 14 retains the roller 21in position and actsas a bearing for same. thrust bearing 23 is POSItiOIIBd'IH the sup- "port 18 thereby taking care of any end I soscrew threaded engagement with the I feed;

screw 3* and is provided at its outer end.

thrust which may occur when the machine is-inoperation.

.Disposed to the rear of and parallel to the axis of the members 4 and 14 is a cam shaft held in suitable bearinlgs supported from the bed ofthe machine. cam 31 is mount-' ed on the shaft 30 and is engaged by a roller 32 carried on a yoked'member 33; A bear ing block 38 on the shaft 30 is slidably mounted between the two arms of the member 33 thereby facilitating the easy move ment of the shaft and the member 33.

At the end opposite to the yoke the member 33 is fastened to an arm 34 by means-of a pivot pin 36 passing through a slot in the member 34. The member 34 is pivotally. connected to the lathe bed 3. Passing longitudinally through the slot 35 in the member 34 and having bearings in each end thereof is a feed screw 37; The feed screw 37 is.

provided, at its outer 'end with a squared head 7 Owhich is adapted to be engaged by a wrench or other toolwhereby rotation .of

the screw can be accomplished. I I

Adjustably secured to the outer end of the arm 34 is a rack 40 which engages a segmental gear 41 loosely mounted on the cam shaft 30. Y

An arm 42 integral with the segmental gear 41 is adjustably secured to another segmental gear 43 also loosely mounted on the cam shaft 30. v

Adjustable engagement betweenthe arm 42 and the gear 43 is accomplished by means of a concentric T slot 44 in the gear 43 and sliding block 45 clamping the arm 42 and the gear '43 together by means of the bolt 46' and the nut.47.

The rack 40 is held in engagement with) the gear 41 by means of rollers 48 onQan;

arm 49 supported from the-cam shaft 30,.

The relative position of the rack 40 and the arm or member 34 is adjusted by means of a squared block :49 adapted to slidably" fit in the slot 35. The block 49 also has with a stud 50 which pass s through abo'ss on the end of the rack 40. The rack'40 is. held on'the stud 50 by means of a nut 51 which engages the threaded end 52 of the.

stud 50: By means of this construction it will be seen that by rotating the screw 37 the rack 40 will be moved either awa from or toward thepivotal connection 0 the arm' 34 to the lathe bed 3, depending on the direction of rotation of the screw-37, thereby controlling the length of movement of the rack 40 over the gear 41.

Mounted on or cut integral withthe driving member 19 is a gear which meshes with the segmental gear 43. Thus it will be seen that any rotation of the cam shaft 30 will cause the roller 32 on the arm 33 to be operated by the cam 31 and will transmit a reciprocating movement to the arm 33, thereby rocking the arm 35 about its pivotal support. The movement of the arm 34 will transmit a reciprocating movement to the rack 40 which will in turn operate the segmental gear 41, and, through the arm 42,v

will operate the segmental gear 43, thereby rotating the-driver thereon. As will be more clearly seen in Fig. 1

the arm 33 terminates at its lower'end in an elongated boss 61. The end of this boss 61- is adjustably fastened to an arm 62,

identicalto the arm 34,, Which is also pivoted,

19 through the,-gear 60 to the lathe-bed 3. A rack 63 is adjustably' secured to the outer end of the arm 62. and meshes with a segmental gear 64 loosely mounted on the cam shaft.

' The gear 64,-joperates another segmental similar. to the, connection between the gears 4141 61 13..- g p A gear 67 onlthe driving member 8 meshes with the segmental gear 65. Thus it will be gear 65 by means of an arm 66 adjustably connecting the gears 64 and 65, in amanner v It 'isf'also obvious that by changing the relative position of .the segmental gears 41 and 43 and64 and 65 by changing the relative, position of each set of gears about the cam shaft 3O in conjunction with the adj usta'ble features of the racks 40 and 63 on the arms '34 and 62 it is possible'to time the relative movements of the members 4 and l4 tosuitthenecessities of the operations required to be performed on the article bev y' the use of the improvement shown it lris possibleto employ two tools in each posiftion of the, turret head which will operate j. f 'onthe article being formed at the same time,

v one being supported from theholes 6 in the 7 member 4 and the other from the slides 16 on the shaft 14, each tool being controlled presented for performing many more operations with different forms of tools than is possible with the former style of turret head in the same length offi-me. I

I have illustrated a number of .tools in position in Figs. 3 and 4 and it is obvious 4 that I may employ different ones than those shown, depending on the requirements of the work-being done.-
