F. F. CLARKE. CLUTCH GEARING FOR MACHINE TOOLS.
APPLICATION F ILED DEC.3| I914.
Patented May 30,1916.
IN VENTOR ATTORN EV III.
. 1,185, Il6d.
Application filed December 3, 1914.
To all whom it may concern Be it known that I, FREDERICK F. CLARKE, citizen of the United States, residing at Franklin, in the county of Venango and State of Pennsylvania, have invented certain new and useful Improvements in Glutch- Gearing for Machine-Tools, of which the following is a specification.
The object, construction and utility of my improved clutch gearing are herein set forth with suflicient clearness to enable those skilled in the art of machinetool construction, to make and use the same.
The gearing here shown is intended, es pecially, more particularly to the feed-screw which actuates the saddle, and to the feed-shaft which actuates the head or ram, which screw and shaft, as is well known, are mounted in close proximity to each other in the crossrail of the mill. It is necessary to so construct the driving gear for said screw and shaft, that either may be selected, at will, to be driven, also that either may be driven in either direction. 'As heretofore constructed, two levers have been employed for this purpose,one to select the element to be driven, the other to select the direction of drive. I have found it to be expeditious, convenient, and conducive to simplicity of construction to employ a single lever for this purpose.
It is, therefore, the object of thls invention to supply such single-lever actuation. The construction whereby I attain said object is clearly shown in the drawings which form a part hereof, the various figures of which are as follows:
Figure 1 is an elevation of said gearing, Fig. 2 is a plan view of the actuating-lever for same, Fig. 3 is a front elevation of the lever-keeper, Fig. 4: is an elevation, with portions brokenaway, of the clutches which I employ in this gearing.
The construction as illustrated in said drawings, is substantially as follows :To the end of the feed-rod (not shown) which actuates the ram of a boring mill, which end projects from the end of the cross-rail, is
secured a primary bevel or miter gear 1, and to the end of the feed-screw which actuates the saddle, and which also projects from the end of said cross-rail, in proximity to said end of said rod, is likewise secured an additional primary bevel gear 2. Within a suit- Specification of Letters Patent.

able frame 3, which is attached to said crossrall, four secondary gears,-4, 5, 6 and 7 are revolubly mounted, upon a vertical driving shaft 8. Gears 4 and 5 mesh with the gear 1, and gears 6 and 7 mesh with the gear 2. Between the gears 1 and 5 a clutch 9 is mounted, and is adapted to engage and to actuate said gears selectively, and as desired. Between the gears 6 and 7 a clutch 10 is mounted and is adapted to engage and to actuate said gears 6 and 7 selectively and as desired.
It will be readily understood that, when gear a is engaged and actuated by clutch 9, it will cause gear 1 to revolve in one direction, and when gear 5 is engaged and actuated by said clutch, it will drive said gear 1 in the opposite direction; also that when gear 6 is engaged and actuated by clutch 10, gear 2 will be driven in one direction, and oppositely-driven when gear 7 is so engaged and actuated.
' Each shipper-sleeve 15 and 16, is provided with a shifting-lever, that for the sleeve 15 being in the form of a straight, horizontallyextending lever 17, and that for the sleeve 16 being in the form of a bell-crank 18, the arms of which form substantially a right angle, with the actuation arm vertically-positioned.
To the outer end of lever 17 is attached one end of a vertically-disposed link 19, and to the outer end of bell-crank 18 is attached one end of a horizontally-disposed link 20: the other end of said links 19 and 20 are joined together by means of a pin 21, and by means of such joining the levers l7 and 18 are adapted to be independently actuated by a single lever 22, the construction, arrangement and operation of which is as follows: The fulcrum point of said lever consists of I a ball-andsocket 23, which adapts said lethe inward position shown bythe fulllines 7 in Fig. 2, by means of the spring 27. A
As previously stated the clutch bodies 11 are splined upon the shaft 8 and positively slide longitudinally upon said shaft."
One application of my improved clutchgearing is further illustrated in my co-pending application for a patent for improvements in feed gearing for boring mills, Serial N 0. 875,330, filed in the United States Patent Oflice at even date herewith.
