Specification of Letters Patent. Patgnted Mar. id, 1919.

Application filed April 26, 1918. Serial No. 30,979.

To all whom it may concern: v

Be it known that I, ERNEST J. lines, a citizen of the United States, residing at c1ty of Cleveland, in the county of uyahoga and State of Ohio, have invented a new anduseful Improvement in Arbor-Supports, of. which the following is a specification, the

particularly to an arrangement for swinging v the same out of the way preparatory 'to mounting of the operating parts.

I am well aware that machine tool supports of this character are not new, and also know that such removal of the arbors has been accomplished both by a swinging movement and by a straight line withdrawal. When the support is movable about a pivot it becomes dificult to accurately center and fix it true to the cooperating spindle. When the support is slid along a squared socket thecenter is held true but the actuation is cumbersome. My idea enables the advantages of each to be had without their disadvantages,

and this I have accomplished by employing a combination. of both of the aforementioned practices, that is to say, 1 provide an arbor support proper which is capable of being swung upwardly, and at the same time I fit the over-arm about which it swings in a square socket so that the center carried by the support is always held true when in position to hold the arbor.

Adverting to the drawings: Figure I is an elevation of a part of a metal working machine showing blank and tool supports together with an arbor support embodying my invention.

Fig. H is a similar view showing certain parts in relatively difierent positions.

Fig. HT is a section on line III-Ill of Fig. I.

A. suitable frame 1 carries a slideway 2 in which a slide adapted to move. The upper surface of the slide 3 is fashioned with a relatively transverse slideway 4 along which a. carriage 5 may be moved through the agency of a screw 6 and -handwheel 7. The carriage 5 is purposed to support any suitable blank not shown. Extending upwardly from the frame 1 is a column 8 provided with a clutch drive collar 9 of any approved type. The top 10 of the column 8 is fashioned with a squared socket not shown but extending in substantial alinement with the axis of thecollar 9. The usual binder handles 11 are provided for fixing within the socket an over-arm.

According to my invention this over-arm has both rounded and squared sections and specifically has a middle portion 12 squared and its two ends 13 and 14 rounded and of somewhat reduced size. The dimensions of the portion 12 are such as to fit within the squared socket of the to 10 of the column 8 so that the over-arm is capable of being moved through the socket when the binder handles 11 are loosened. As will be readily cupies the squared socket the over-arm may be turned around.

Fitted around the squared section 12 is a split arbor support 15 having adepending extension 16 which carries a center 17 adapted to occupy a position in axial alinement with reference to the clutch drive collar 9. The support 15 may be clamped to the section 12 by a similar binder handle 18. An arbor 19 carries a tool 20 and 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 which it is loosely held in place by an end collar 21 so that it may be swung upwardly and out of the way when it is desired to remove the arbor 19, as appears in Fig. II.

it will be observed that l have provided an alternative means whereby the arbor support may be swung out of the way. In addition to the mode of doing this, as illustrated in Fig. Il, the support 15 may be left secured to the section 12 and the over-arm bodily withdrawn after loosening the bandles 11 until the rounded section 13 occupies the socket formed in the top 10 whereupon the over-arm and arbor support may be turned around as a unit.

The advantage which my structural arrangement offers is that it enables an arbor support to be swung upwardly out of 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 tightened with absolute assurance that the center 17 is in precise alinement with the collar 9 as is requiredfor 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 slidably attached to an upright standard is to be construed as the equivalent of the adjustable column extension or overarm. The essential idea is that a pair of 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. The 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 overarm and support around as a unit without requiring a loosening of the handle 18.

I claim:

1. An arbor support comprising a column provided with an angular socket, an overarm having a section of corresponding angularity as and fitted in said socket, another section of said over-arm being rounded of reduced size and adapted to be withdrawn into said socket, and an arbor support fitted to said angular section and adapted to be swung around when such rounded section occupies said socket.

2. An arbor support comprising a column provided with an angular socket, an overarm having a section of corresponding angularity as and fitted in said socket, means for fixing said arm therein, other sections of said over-arm being rounded and of reduced size, and an arbor support fitted to said angular section, means for so fixing said support, the latter adapted when loosened to he slid along to inclose one of said rounded sections, the other rounded section being adapted to be withdrawn into said socket,

whereby a double provision for swinging said support out of the way of said arbor is had.

3. An arbor support comprising a column provided with a clutch drive collar and a socket of angular contour having parallel axes, an over-arm fitted in said socket, means for fixing said arm in place therein, an arbor support having a socket fitted about said over-arm, means for fixing said support to said arm, a center carried by said support and adapted to rest coaxially with said clutch collar for mounting an arbor in conjunction therewith, a section of said arm being rounded and adapted to occupy one of said sockets whereby to enable said support to be swung around.

4. An arbor support comprising a column provided with a clutch drive collar and a socket of angular contour having parallel axes, an over-arm fitted in said socketand having one end rounded, means for .fixing said arm in place therein, an arbor support having a socket fitted about said over-arm, means for fixing said support to said arm, a center carried by said support and adapted to rest coaxially with said clutch collar for mounting an arbor in conjunction therewith, such rounded end of said arm being adapted to occupy one of said sockets, the arrangement being such that a relative axial movement of said arm and one of said sockets may be efl'ected upon loosening one of said fixing means so as to withdraw said center from said arbor and thereafter enable the support to be swung out of the way preparatory to removing the arbor.

5. An adjustable column extension comprising a column with an angular recess and a bar having both angular and round sections, either section of which will fit in said angular recess.

6. A device of the character described comprising a fixed member, and a member movably carried thereby, means for fixing said members together, one of said members being provided with an angular aperture into which the other projects whereby to enable sliding straight-line movement therebetween, the other of said members being fashioned both with a round section of corresponding diameter as the distance between opposite points in said aperture and with an angular section fitted to the walls of said aperture whereby both sections may be caused to occupysaid aperture for the useful purpose specified.

7 A device of the character described, comprising a column and an over-arm carried thereby so as to be capable of distinct movements relatively thereto one such movement being prevented during certain stages of the other for the purpose specified.

8. A device of the character described,

ios

comprisin I a column and an over-arm carried there y so as to be capable of reciprocal and swinging movements relatively thereto, the arrangement being such that said swinging movement is hindered until one direction of said reciprocal movement has progressed to a given point.

9. A device of t the other end of said structure e character described, comprisiri" a column formed with a clutch 10 collar an an angular structure having one into line with the axis .of said collar at a 15 predetermined stage of one of said relative movements.
