DRILL-PRESS.

$PECIPICATION forming part of Letters Patent No. 361,105, dated April 12, 1887. Application filed December 4, 1886. ScriaINo. 2:0,687. (No modcll) To all whom it may concern:

Be it known that I, J AMES F. WINoHnLL, a citizen of the United States, residing at Springfield, in the countyof Clark and State of Ohio, have invented certain new and useful Improvements in Drill-Presses, of which the following is a specification, reference being had therein-to the accompanying drawings. 7

This invention relates to improvements in dril1-presses; and it consists in constructing the work-table with a plurality of arms anda like number of tables; and the object I have in View is to provide for holding different kinds of work upon different tables, whereby, when the holding devices of one table are set, say, for holding fiat work, the holding devices of the other table may be set, say, for holding angular or other shaped work, thus effecting an important saving of time otherwise lost in changing from a table having holding devices for one kind of work to a table having holding devices to hold another and different kind of work. This saving of time is also gained in case but one table is used with the bracket as now constructed and several kinds of holding devices fitted to it. Again, it almost daily happens, especially in shops where a variety of work is done, that the holding devices are set for holding a peculiar piece of work which requires time to complete; and when other and simpler work is ready for the drill-press this work must either be delayed or it becomes necessary to change the accurate adjustment of the holding devices already set for the other work. This is exceedingly inconvenient, is. time-consuming, and frequently results in producing inaccurate workmanship in readjusting the holding devices for the more difficult work. Myimprovement, however, entirely avoids these existing difficulties, as will more fully appear in the following description.

In the accompanying drawings forming a part of this specification, and on which like reference-letters indicate corresponding features, Figure 1 represents a side elevation of the lower portion of any ordinary drill-press, showing myimproved table-bracket applied to the column thereof; Fig. 2, aplan view of the bracket with the tables thereon; and Fig. 3, a

like view of the bracket alone, showing more clearly its plurality of arms.

The letter Adesignates the base, and theletter Bthe vertical column,of-adrill-pressof the ordinary or any approved construction, the

drill-operating mechanism being omitted. The

letter 0 refers to the Work-table bracket,which consists in part of the collar D, fitted to the press-column and divided at one side, andhaving screw-threaded lugs and a clamping-screw, whereby the collar is made to snugly fit, yet not unduly bind, upon the column, and by means of which it may be securely clamped. The bracket further consists of the arms E, of which there are two or more, and which stand ontfrom the collar, and preferably terminate 6-; in upper horizontal surfaces, where they are I vertically bored to receive the short shafts of the work-tables. These are also divided at their ends, as seen in Fig. 3, and provided with lugs and clamping-screws, whereby they are made to bind and duly secure the table-shafts. These arms are further, by preference, of skeleton construction, to reduce their weight and lessen the consumption ofmetal. Journaled in one of these arms is the usual pinion-shaft, H, having apinion, I,which meshes with the usual rack-bar, J,ofthe column,to adjust the bracket with respect to the drill or bit.

The letters K and L respectively represent the flat work and the irregular or other shaped 8o work-table, which I thus designate for purposes of illustrating my invention. These tables are, constructed in the usual or any approved way, and are in use provided with the known clamping or work-holding devices, andin the draw- 8: ings herewith the table L isprovided with a I chuck, M. The drill is illustrated at N in Fig. 1, and the table K is shown as swung under it. Thus one table may bein use with one kind of work 011 it while the other table is beingsupplied with another description of work, and yet no time lost, and when the work on the table K is finished the table L may be instantly swung under'the drill.

The ways in which the utility of this arrangement has manifested itself are exceed- 1 1ngly numerous, as I have often found in practical use in a manufactory with which I am connected, and as is obvious to any mechanic. I would therefore have it understood that I believe myself the first to invent, in a broad sense, a bracket for drill-press worktables with a plurality of arms for supporting the work-tables, whereby the desirable ends herein indicated are accomplished.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a drill-press, the bracket forsupporting the work-tables, constructed with a pinrality of arms and withacollar which fits the press-column, in combination with a table for each arm.

2. A bracket fol-supporting the work-tables of a drill-press, constructed with a plurality of supporting-arms and adapted to be con nected with the press-colu1nn.

3. Abracket for supporting the work-tables 20 of a drill-press,constructed with a divided c01- lar and with two supporting-arms having divided ends,whereby the collar is adjusted to the column and the arms to thetable-shafts.

4. In a drill-press, the combination, with 25 the column and the drill, of the bracket fitted to the column and having" a plurality of supporting-arms, and tables supported by said arms and adapted, respectively, to different kinds of work.

In testimony whereof I affix my signature in presence of two witnesses.
