LOCKING MECHANISM FOR MACHINE TOOLS.

ADOLPH L. DE LEEUW, OF HAMILTON, OI-IIO, ASSIGNOR TO THE CINCINNATI MILLING MACHINE COMPANY, OF CINCINNATI, OHIO, A CORPORATION OF OHIO.
LOCKING MECHANISM FOR MACHINE-TOOLS.
Specification of Letters Patent.
Patented June 2, 1908.
Application filed October 7, 1907. Serial No. 396,240.
To all whom it may concern:
Be it known that I, ADOLPI-I L. DE LnEUw, a citizen ofthe United States, residing at Hamilton, in the county of Butler and State of Ohio, have invented certain new and useful Improvements in Looking Mechanism for Machine-Tools, of which the following is a specification.
The main object of my invention is to pro vide two or more independent looks of the clamp type, actuated through a single control, the principle of the clamps being such, that each is capable of independently and automatically compensating for wear or lost motion without in any wise affecting the operation of the control.
My invention relates more particularly to means for detachably holding and looking a supporting element of a machine such as the overhanging arm of a milling machine. This overhanging arm, as is well understood forms the support of the tool mandrel, and it is desirable to provide means whereby it may be readily removed or locked in position. This overhanging arm is ordinarily supported in two collars formed at the top of the machine frame, and it has been customary to lock the arm independently in the two collars. This arrangement was mechanically disadvantageous and inefiicient.
My improvement is directed to the provis'ion of means for simultaneously locking the arm at each end of its support, and also the provision of a strong support and lock which can be readily manipulated, and which will.
automatically accommodate itself to wear.
The features of my invention are more fully set forth in the description of the accompanying drawings forming a part of this specification, in which Figure 1 is a central vertical section through the support showing the arm in position. Fig. 2 is a section on line 00, r, Fig. 1. Fig. 3 is a section on line y, y, Fig. 1.
The support may consist of two independent collars projected upwardly from the frame of the machine abovethe spindle, but
referably I construct the support in the form of a solid sleeve 1, suitably bored to receive the overhanging arm 2. The sleeve 1 is provided with the pockets 3, 4, forming the housings for the locking mechanism, and the sleeve is also provided with a bore for containing the locking rod 5, which extends opposite longitudinally through the sleeve casting in parallel line with the arm 2.
Within the pockets 3, 4, are the shoes 6 having segmental faces bearing against the periphery of the arm 2. The upper faces of the shoes 6 are upwardly inclined toward the front of the machine. The rod 5 is provided with the offsets 7, the upper walls of which are inclined at a greater angle to the horizontal than the angle of inclination of the upper faces of the shoes 6. Between the inc ined opposing faces of ofisets 7 and shoes 6 are placed the rollers 8. These different inclines are employed in a horizontal lock.
The front end of rod 5 is screw threaded and this end is engaged through an adjusting collar 9. When the rod 5 is drawn forward the tapered offsets 7 will force the rollers 8 downwardly upon the segmental shoes 6, and
simultaneously clamp these shoes forcibly against the arm 2, thus securely looking it at each end of the sleeve in one movement. The normal tendencyof the rollers 8 when free, is to roll down the inclines of the shoes 6, so that when the rod 5 is moved to the position the'locks are instantly released. The engagement of the roller bearings between the clamping faces having different degrees of inclination, forms means which automatically compensate for wear or lost motion.
The structure is strong, manipulated.
Itv is obvious that the principles of the invention can be utilized in connection with any detachable arm or supporting member of a machine which has to be securely locked to the main machine frame, and that the automatic and independent adjustability of the clamp shoes to wear, is applicable to a variety of uses in connection with a member to be locked.
Having described my invention, I claim 1. A member to be locked, two or more clamping shoes, an operating rod, the rod and shoes having opposing inclines, and interposed bearing devices, substantially as described.
2. In a machine of the class described, a support, an arm removably held therein, locking shoes held in each end of the support and bearing against the arm, a rod having tapered offsets adjacent to the shoes, bearing ro lers interposed between said offsets and simple, and easily shoes, and means for longitudinally adjustposed between said inclined faces, and means ing the said rod in said support, substantially for longitudinally adjusting the rod, substanas described. tially as described.
