EDWARD J'. KEARNEY, WAUWATOSA, AND THEODORE TRECKER, WEST ALLIS,
WISCONSIN.
MILLING-MACHINE.
Specication of Letters 'Patent'. Application filed May 29, 1912.
Patented Feb. 18, 1913. Serial No. 700,379.
To all 'whom it may; concern: v
Be it known that we, EDWARD J. KEAR- NEY and THEoDonn TRE'oKEn, citizens of the United States, residing at lVauwato'sa and West Allis, respectively, county of Milwaukee, and State of Wisconsin, have invented new and useful Improvements in Milling- Machines, ofwhich the following is a specif lication.
Our invention relates to improvements in milling machines.
` The object of our invention is to provide a rigid" over-arm structurel for milling inachines, whereby the out bearing hanger arm may be securely held in the exact position required for supporting the arbor.
In carrying out the above object, we employ a. set of parallel over-arms, with both of which the out bearing-hanger is adjustably engaged, and we also provide means whereby either one of the over-arms may be removed, either wholly or partially, inde pendently of the other, to allowA the out bearing hanger to'be swung to a position of non-use in substantiallyr the same manner as in the milling machines heretofore constructed with a single overarm.
In the drawingsv-Figure 1 is a front elevation of a portion of a .milling machine embodying our invention. Fig. 2 isa side elevation of the same.
Like parts are identified by the same reference characters in both views.
1 is a milling' machine column provided with a cap member 2, preferably integral with the column and provided with parallel e1't1u'es to receive a plurality oi over-arms 3 and 4, which are mounted" to slide through the column apertures, in lwhich the ov'erarms closely it. 'lliey can be rigidly secured in position by Slottingij the cap'member in a horizontal plane and employing clamp- 'ing bolts G to `torce the upper part of the cap downwardly, the slots 7 permitting such downward movement and the` material of which the cap is composed 'yielding sutiiciently to allow the parts to bind upon the over-arms 10 is a hanger or out bearing member, adapted to support the arbor outlbearing member 11 from the over-arms 3 and 4, which over-arms pass through suitable openings in the upper portion of the hanger.
This hanger is provided with slots 12 extending vertically from its over-arm apertures to its upper margin, whereby the hanger may be clamped upon the over-arms by a cross bolt 13 and nuts 14.
Then the hanger is in position et' use, as shown by full lines in Fig. l, itis rigidly supported by both of the over-arms 3 and 4, and it is therefore impossiblefor its lower end to be out of line with the axis of the i arbor actuating' spindle. It is also impossible for the hanger arm to swing' from side to side and cramp the arbor. It it is desired to swing,r the out bearing hanger' arm to a position of non use. as indicated by dotted lines in Fig'. 2. it is merely necessary to loosen tho clamping' bolt 13 and-push one of the over-arms 3 or 4 inwardly ,through the column cap 2. whereupon the hanger arm may be swung -upon the other over-arm to any desired position. ,and if necessary, locked in such position byfth'e inuts 14 and bolt 13. When the out bearing hanger 10 is in position of use, it will not be necessary to clamp the same in position on the overarms 3 and 4. except to prevent longitudinal movements, all lateral or swinging movements being prevented by employingr a plurality ot' over-arms. v i lVe claim- 1. The combination witha milling machine column, of a plurality of over-arms adjustably mounted in said column, and an ont bearing' hanger adaptedto support a cutter arbor and detachably engaging each of said over-arms.
2. The combination with a :milling fnachine column, of a plurality of over-arms adjustably mounted in said column, and an ont hearing hanger adapted to support-a` cutter arbor and detachably engaging' each of said over-arms, said over-arms being each adjustable independently of the other' into and out of supporting relation to the out bearingr hangre In testimony whereof we aliiX our signatures in the presence of two witnesses.
EDWARD J. KE ARNEY.
