This invention relates to metal working machines in which a cutter or work spindle is provided with an end support bearing, it particularly relating to gear-cutting and milling machines, the object of the invention being to provide an improved spindlesup porting member-for such a machine.
Arbor supports on differentkinds of milling machines, including car cutters, have been in use for a considera le length of time.
"side swiveling support.
2 swiveling arbor support was probably first used on horizontal milling machines in such a way that the support consisted of a cylindrical shaft carrying the arm in a cylindrical .bearing. The arm when not in use could then be swung out of the way in a plane at right angles to, the axis of the support. To make such swiveling arbor supports more rigid, the support itself was later on made in box form, but this necessitated the introduction of a vertically pivoted member between the arm and column support which impaired the rigidity of this swiveling box type of support to a certain extent, although it permitted the side' swivellin of the armin a plane at right angles to t e axis of the support. 7
In the present improvement the pivotal or swinging arbor support isso connected with the-supporting column that it may be swung vertically to a position in alinement with the supporting column, so that it is en- 'tirely out of the way, which is not'alwa s the case with' that type of support, where t e suppbrtin arbor is swungsideways or at right ang es to the column 'or support, the
present improvement .not interfering with the necessary rigidity of the structure.
In the drawings accompanying and form-,
ing a.- part of this specification,--
Fig.- 1 is a side elevation of this improved spindle-supporting means;
Fig. 2 is a top view thereof;
Fig. .3 is a perspective detail view of the upper part of the column or support;
Fig. 4 is a detail'view of the ear mechanism for raising and lowering t e supporting arm; and a Fig. 5 is a view illustrating the manner in which the supporting arbor may be applied to a milling machine.
Similar characters of reference indicate corresponding partsin the several figures of the drawings.
Before explaining in detail the resent improvement and mode of operation t ereof, I desire to have, it understood that the invention is not limited to the details of construction and arrangement of parts which are il- 1 lustrated. in the accompanying drawings,
since the invention is capable of other embodiments, and that the phraseology which I employ is for the not of limitation.
In the structure shown in Figs. 1 to 4,
which is particularly adapted to support the work spindle of a gear-cutting machine a box-type form of column is provided WhlCh ma be secured in any suitable way to a base, an this column is formed as a two-part structure, the top or head member 3 thereof being horizontally pivoted by journals the top of'the lower part or base 2 of the column so that the part 3 may be swung in a vertical direction toward or from the face or front ofthe column. When swung vertically upward a part of the head member 3 {will swing within the recessed or bifurcated top portion 2' 51sec Fig. 2) of the column 2, as indicated by otted lines in Fig. 1, suitable clamping means 5 being provided for holding the vertically swinging member 3 in either its working or non-working position. The face or forward side of the swinging head member 3 and base 2 of the column are provided with alined guideways 6-and 7 for the purpose of description, and
with an o ening 10 coaxial with the work spindle to e supported. For thepurpose of raising and lowering the arm 8 upon its guideways suitable gearing is provided and in the present instance the to and bottommembers of the column are provided with alined racks 11 and 12 in mesh with which is a worm gear 13 carried by the supporting arm 8 having a bevelled gear 14 in mesh with a companion bevelled gear 15 carried by a hand wheel shaft 16 on the outer end of which is a hand wheel 17. The rotation of thishand wheel rotates the worm gear 13 and thereby raises and'lowers thearm 8. When it is desired to swin the arm 8 out of the way it is unclampe from the base 2 of the column-and shifted upwardly by the means described, so as to engage the head or top part 3 of the column, w ereupon the arm of the column head 3 may be thrown upward into the-position shown in dotted lines in Fig. 1, so that r it is entirely out of the we and in this position it may be clamped y the clamping means 5. The arm 8 and the head part 3 of the column at this time rest upon the base 2 of the column. When it is desired to use the arm again it is merely necessary to unclamp the clamping means 5, throw the arm and column head downward upon its journals 4 and then operatev the hand wheel to shift the arm into any desired positionto receive the spindle or arbor as shown in full lines in Fig. 1.
p 3' may be swung vertically The present improvement is alsoadapted for use in milling machines in which the support is likewise made in. two parts 2" and 3 pivotally secured together so that the part said parts 2" and 3' being provided with a slideway 4' for the reception of an arbor-supporting member 5' so that when this member 5 is moved onto the guideway. of the part-3' the samemay be swunupward in the manner heretofore described in connection with Figs. 1 to 4,
thereby releasing the arbor or spindle of the milling cutter 15.
It is to be understood that by describing in detail herein any particular form, structure, or arrangement, it is not intended to limit the invention beyond the terms of the several claims or the requirements of the prior art.
Having thus explained thenature of my said invention and describeda way of constructing and using the same, although without attempting to set forth all of the forms inwhich it may be made" or all. of the modes of its use, I claim:
