ARBOR SUPPORT;

Original application lediAprl 26,1918, Serial No. 230,979. Divided and this application led. February.' Serial No. 275,685.

T o, all whom t may concern: y

Be it known that I, ERNEST J. LEES, a citizen of theUnited States, residing at No. 621.0 Carnegie Ave., Cleveland, in the 'county 5- ofy Cuyaho'gaand State of' Ohio, have invented a new. andv useful Improvement in Arbor Supports,l of which the following is al specificatiomthe principle of the invention being herein explained and the best mode in 101" which I have contemplated ap-plying that principle, yso as t'o distinguish it from' other inventions. l

This invention pertains to an arbor support for metal. working'fmachine's, and more 15'* particularly 't'o an' arrangement for swinging the same, out ofthe wayyfpreparatory 'to I.

mounting of" the operating parts.

I am well'awarefthat' 'machine tool supports ofv this' character are not' new, and also 201 know that'v s'fuchV removal of' the' arbors has been'accor'nplishedV both by a swingingmovjement and by a" straight line withdrawal. vWhen the support'l'is movable about'a pivot itv becomes difficult to accurately center and fix it true to the cooperatingspindle. When the ksupport is slid along a square socket the centre is held true butthe actuationI is cum# bers'ome. i Wy'idea enables the advantages of each to be had ywithout their. disadvat'ages,

3o' and this I have accomplished by employing a'combination of'both oithe aforementioned practices, that is to say, I provide anarb'or support proper which is capable of'being swung upwardly and at the Sametime I t Sarthe over-arm about which it swingsin a square sockets@ that the center carried by the' supportis always held true when in position to hold the arbor. y

Adverting to the drawings:

Figure I' is an elevation of, a part of a metal working machine showing blank and tool supports'togethe-r with an arbor supportembodying my invention.

Y Figure II is a similar view showing certain, parts -in relatively different positions.

'Figure'jIIIfis' yaff section on linelIIIeIII-Yfof,

Figure-i:

`Afsu `which 'slidej 'is adapted to nieve.` The 'lupper surface of the slide 3 isfashioned with amrelativelytransverse slideway t along which abarrage '5 may bamoved' through this ageney of a- 'screw `6 andjhandwheel 7.-' The carriage is 'pui-posed' tol support any itableframel carries aslideway 2 in has, both' rounded and squared'. sections and@ speciically has a middle portion 12' squared andits ytvvo ends 13 and1 kerounded and. oli

somewhat reduced size. The dimensions 'of the portion 12'are such as to, within the squared socket or the top` 10 ofthe column Ssothat the over-arm is capable otbeing` moved through the socket when the binderhandles 1v1 are loosened; As will be readily understood, when the over-arm is. withf drawn to the right soj that the rounded end` i 13y occupiesthe squared socketlthe over-arm may` be turned around. n y Fitted around the squared section 12v a split arbor support 15 havinga depending` extension 16 which carries a center 1 7 adapted to occupy a position in'axial alignment with reference to the clutch drive collar 9. The support 15 may be clamped tothe section 12 by a similar binder handle 18. arbor 19 carriesa tool 20and is mounted to rotate between the collar 9 and center 17. It will be evident that when the handle 18 is loosened the arbor support .15 may be. slid from the squared section 12 on to the round extremity 14 upon ywhich it is'loosely.y

held in place by an endcollar 21 so that it may be swung'upw'ardlyand out, oftheway whenv it isdesiredto remove the arbor 19 as appears in Figure II. ;A

It will be observed that I have provided an alternative means whereby they arbor support maybe swungout of the. way. In addi.-

tiontotlie inode ottV doing this, as .illustrated in FigureIl, the support 1 5 may belettv secured to.the;sectionY 1 2 andutliefoverjarm. bodily vwithfdfrawn.y vafter lOcseningl.v the; handles 1 1 untilfth'e rounded sec'gtion- 13 occupies the socket formed in the. top10 whereupon the over-arm and arbor support may beturned around as a. unit.`vv

The advantage. ywhich my. structuralf-are. rangement 05ers is that# enables' Werber., vsupport tobe 'swungupwardly out Iof the way and yet permit of its being returned to its functionating position and there fixed so that the center 17 is always accurately pointed Whenever the section 12 extends not only into the socket provided in the top 10 but also into the support 15. The handles 11. and 18 may be tightenedvfith absolute assurance that the center 17 is in precise alignment with the collar 9 as is required for the proper operation of the tool.

It is to be understood that the application of this invention is not to be considered as limited to any particular kind of metal working machine and therefore not applicable solely to a support for an arbor, notwithstanding the arbitrary title selection. Any member slidablyattached to an upright standard is to be construed as the equivalent of the adjustable column extension or over-arm. The essential idea is that a pair of members are so designed and connected to permit of distinct relative movements. According to the eXempliica-tion of the drawing one of such members is formed with an angular socket and the other with both a corresponding angular section and with a round section which latter section is however likewise fitted to said socket to enable it to be swivelled therein. Any side of the angular section may be said'to be tangential to the rounded section. It will be understood, moreover, that while a perfectly round section is preferable a slight variation therefrom might be permitted without departure from the principle of enabling a turning movement within the angular socket. rlhe underlying scheme is of course duplicated in the structure illustrated because the distinct relative movements may be accomplished either as between the column and over-arm or as between the over-arm and the support 15, thus giving the operator the option of swinging the support by itself around the over-arm, or swinging both over-arm and support around as a unit without requiring a loosening of the handle 18.

This application is a division from the application which eventuated on March 11, 1919 as Patent Number 1,296,821.
