asflt'o 'enable l'oca'ting'a tool-head 'to-one or both'si'desof and in sp'aced're'lationto a work table. I p p I Still a 'furitherobjet 'of the invention is to afford mechanism in conjunction with a crank planer forsimultaneously feeding toolheads'loc'ated respectively above and to one side of the work for cooperation with the top and sides thereof, such feeding being ef fected simultaneously and in a predetermined relation. 7

With these ends in view, the invention comprises the construction that will appear clearly from the following description when read in conjunction with the accompanying drawings, the features of novelty being pointed out in the claims following the description.

In the drawings:

Figure 1 is a front elevation of a conventional crank planer having applied thereto one embodiment of the invention;

Figure 2 is a side elevation of the same, and

Figure 3 is a horizontal sectional view taken on the line indicated generally at 3-3 of Figure 2. k

Referring more particularly to the drawings in which like reference numerals refer to the same parts in different views, 1 designates a base or bed upon which is mounted a work table 2 for reciprocatory movement with relation to the tools. The work table 2 is given a quick return movement through the action of crank mechanism that is controlled from the motor 3 and operatively connected with the work table through parts such as are well known in the art and therefore unnecessary to illustrate in detail.

4 and 5 designate uprights or standards upon which is mounted for vertical adjusttool-hea ds- -need not necessarily be: the same,

ment the crossrailtihaving atool-head 7 mov- I able thereon and adapted to support a tool for cooperation with the upper surface of the work. The upright '5 extends to a point beneath the top of the work table, and is spaced laterally at one side thereof. The standard 5*is adapted to receive a side tool head 8 which can be fed vertically on the standard fi'beneath the crossrail, and is movable to a position beneath the top of the-6 table, as illustrated in Figure lso as to bring its tool into cooperative relationship with a side of the work, this arrangement permitting simultaneous operation upon-the top and a side of the Work. Under suchconditions it 6 is desirable to provide for simultaneously feeding both the-top and side tool hjeads, and

this is accomplished by the following mechanism. 1 The crank shaft, which effects movement of the iwork' table, is provided with a crank 10, see Figurefi, andcrank arm 11 connected to amend of arocker arm 12; The rocker arm 12 1 is pivoted at 13 1 and {ha-s its opposite end-'14 connected to anactuating devicepreferably comprising a vertically 'arranged re- 'ciprocatory rack 15' which cooperates with a "suitable gear formingpart of a feed mechan-ism designated generally at 17 for effecting the necessary lateral feeding of theltop toolhead 7 on crossrail 6, through a screw 18.

Theside'tool-headdis fed by a'vertical screw 19 extending through thestandard. 5 which carries at itslower en d' abevel pinion 20 enga'ged by a bevel pinion 21. The latter is controlled vthrough gearing including pinion 22, gear 23, and gear 24, see iFigurei-S, the; gear 24 being engaged and actuated by the aforementioned actuating device on. rack 15 'at'thedower'end of the latter. I It will be understood-that onefof the gearsin the trainfjustreferred'to has an operating movernent only in Zone direcion, as welliknownin this ty-peof feeding mechanisms, andthat :duringtheoperatingstroke of the 'rack15, the 9 mechanism just described-serves tomovathe side i tool-head *8 verticallygat the a same .time that the top tool-head 7 is fed 1 horizontally. The amount of feeding of the respective 26 extending around pulleys 27 and 28 and thence downwardly through the opening 29 in standard 5, which serves also to house the aforementioned vertical screw 19.

Although only one side-head has been.

shown and described, the construction of upright 5 and its side-head 8 may be duplicated for upright e, affording tools and tool controlling mechanism on both sides of the work table, similar to that already described.

While the invention has been described with reference to a particular arrangement, it is not confined to the precise details herein set forth, but may be modified within limitations Without departing fromthe primary accomplishments of the improvement or the scope of the following claims.

a I claim:

1. In a crank planing machine, the combination with a work table and c 'ank mechanism for imparting a quick return movement thereto, said crank mechanism including a crankshaft for controlling movement of the Work table, of uprights, a crossrail adjustable on said uprights, one of the uprights extending to a point beneath the top of the work table and spaced laterally therefrom, a tool head movableon, the crossrail, a second tool head movable on the last named upright to 'a point beneath the top of the work table and opposite one side thereof, feeding mechanisms for the tool heads, a common actuating device cooperating with said feeding mechanisms, and a crank on the aforesaid crank shaft operatively connected to said common actuating device.

2. In a crank planing machine, the combination with a work table and crank mechanism for imparting a quick return movement thereto, of uprights, a crossrail adjustable on said uprights, one of the uprights extending to a point beneath the top of the work table and spaced laterally therefrom, a tool head movable on the crossrail, a second tool head movable on the last 'nameo upright to a point beneath the top of the work table and opposite to one side thereof, a feed screw arranged vertically in said upright for controlling the last mentioned tool head, feeding mechanism located at the bottom of said upright below the work table and operatively connected to said feed screw, of feeding mechanism for the first mentioned tool head, a common actuating device cooperating with said feeding mechanisms and operating to simultaneously feed the tool heads laterally and vertically respectively, and operative connecting means between said crank mechanism and said actuating device.

3. In a crank planing machine, the combination with a work table and crank mechanism for imparting a quick return movement thereto, said crank mechanism including a crank shaft for controlling movement of the work table, of uprights, a crossrail adjustable on said uprights, one of the uprights extending to a'point beneath the top of the work table and spaced laterally therefrom, a tool head movable on the crossrail, a second tool head movable on the last named upright to a point beneath the top of the work table and opposite one side thereof, a feed screw arranged in said upright for controlling the last mentioned t-ool head, feeding mechanism located at thebottom of said upright below the work table and operatively connected to said feed screw, feeding mechanism for the first mentioned tool head, acommon actuating device cooperating with said feeding mechanisms and operating to simultaneously eed the tool heads laterally and vertically respectively, a crank on the aforementioned crank shaft, and a connection between said crank and said common actuating device.

In witness whereof, I have hereunto signed my name.

ALFRED TROSCH.
