SPECIFICATION forming part of Letters Fatent No. 645,554, dated March 20, :1.900.v Application iiled October 10,1899. Serial No. 738,179. (No model.)

T all whom/z5 may concern: j

Be it'known that I, FRANK DIEHL, a citizen of the United States, residing at Sheboygan, in the county of Sheboygan' and Stateof Wisconsin, have invented a new and useful Planer Attachment, of which the following is a specitremity opposite the attached end/thereof,`

controlling mechanism includinga counterpoise, the device being adapted fori use vwith p one or more planers' below the same or above 2o the level thereof. l

Other objects and advantages will appear in the subjoined disclosure of the structural features of the invention and the novelty will be hereinafter claimed, a preferred embodiment of the invention being illustrated in the accompanying drawings, wherein#- Figure 1 is a diagrammatic view in sectional elevation illustrating a number' of plauers at different elevations and the improved jack in side elevation. Fig. 2 is a top'plan view of the improved jack, showing hangers for a Apart thereof in section. Fig. 3 is a transverse vertical section through the controlling mechanism. Fig. 4 is a longitudinal section through the controlling mechanism. A

Similar numerals of reference are employed to indicate corresponding parts in the several j views. f

The numeral 1 designates a line-shaft, to which the jack 2 is movably fastened by boxes 3. The jack hangs horizontally in a plane at right angles to the said line-shaft 1 and is automatically adjustable above and below said plane and controlled by mechanism which will be presently described. On the line-shaft, between the boxes 3, is a driving-pulley 4, adapted to be traversed by a belt 5, which runs to a receiving-pulley 6, fixed on a jack-shaft 7, mounted in boxes 8 on the outer extremity of the jack-frame 9. The motion of the shaft7 is transmitted te different points by means of one or more pulleys 10, traversed by suitable obvious that a number couldbe used or a compound pulley capable of receiving a number belts, as 11, which are crossed V te obtain the j` proper. direction of rotation, and although of belts might also lbe employed. These vare l l mechanical substitutions well understood in the art of pulleys and shafting and have not been specically disclosed in the drawings for l this reason.

The jack-frame` 9 comprises opposite side bars12, having their rear extremitiesconnected to the boxes 3 andat thefront are made continuous byineans of a yoke 13. yThe side bars 12 preferably converge from'the box y toward the yoke 13, and adjacent vthe box 8 vvertical openings 14 are formed in the said side bars 12 .tol receive oppositely-disposed safety-rods 15, which are hung fromthe flooring above orv any other suitable support and have their lower` extremities threaded to re- ,l

pressed without bindingand an adjustment can be `acquiredby moving'rthe nuts 17 on the screw-threaded extremities-16, aswill be read# ily apparent.v -The purpose of. these safetyrods is toprevent the jack from falling in the event of disconnection of the boxes 3 or breakage ofthe frame, and thus avoid serious yconsequences to workmen below should such severance take place. y

To the .central part of the yoke 13a pair of links 18 are pivotally connected and at their j points of 'attachment embrace a lug 19. vThe upper endsof the links are movably secured n 13o-the arm20 of a bell-crank lever 21, which is fulcrurned on a rock-shaft 22, journaled at opposite extremities in the lower portions of a pair of hangers 23, also dependingfrom-the ioor above and adjacent which are another pair of hangers 24 to provide a'bearing for a second rock-shaft 25 in their lower extremities, on which is iixed a bell-crank lever 26. The arm 2O of the bell-crank lever 2l, to which the links 18 are connected, extends in the direction of the jack, and the arm 27 of Ysaid bell-crank lever is connected to the upper arm 28 of the bell-crank lever 26 by a connecting-rod-29.. To the other arm 30 of the bell-crank lever 26 a counterpoise-weight 31 IOO 2l being longer than the arm 28 of the bellcrank lever 2G it is necessary to locate the shaft 22 in a plane below thatof the shaft 25 in order to'have the connecting-rod 29 Vwork in awhorizontal plane, 'which is essential in view of the fact that the reverse arrangement of the bell-crank lever increases the sensitiveness of the'controlling mechanism and establishes a compensatory combination of elements that will conjointly. work in a practical manner to attain the desired result.

From an observation of the showing in Fig, 1 it will be seen that the planers can be belted either up or down or at any angle desired. When upper planers are belted to thc jack,

the` counter-poise or weight 3l must be lighter than whenthe jack is belted to a planer bcneath the same, and it isobvio'us that'the belts will be run through the flooring when the planers are above the jaclgand such other appliances as may be necessary will be used andef-a form well known 'in the art to assist inthe direction of the belts.

runs downwardly to the planer-cylinder 33,

and insome instances it will be preferred io have the said cylinder directly under the jack, as in the particular one of the planerswhich has been referred to. In all the arrangements the jack works automatically through the medium of the counterpoise or weight 3l, and, againrreferring to the planer 32,when the planer-bed is loweredthe jack swings' downwardly with the strain of the belt 1l at an angle tothe said planer and a distance corresponding with the adjustment of thebed.

This downward movement of the jack is exerted against the resistance of the counterpoise or weightl, and when the planer-bed is raised to itshighest point the said counterpoise or weight raises the jack. The other planers shown below the jack on opposite sides of the planer 32 will also produce a similar movement of the jack when their beds are raised or lowered, as well as the planer shown overhead or above the jack, wherein, for instance, the planer-cylinder is up, and the adjustment of the bed in a similar direction will raise the jack against the resistance of the weight 31, and a depression of the bed of this Referring now more particularly to the under planer, (desig-y nated 32,) it willbe observed that the belt 11 planer will allow the jack to return tol its normal horizontal position. This same adjustable characteristic of the jack is followed out uniformly in the several arrangements of the planers, and the weight 3l is varied to suit different arrangements, and particularly in connection with the overhead planer, as before indicated. y

Having thus-described the invention, what is claimed as new isp l. The combination with a power-shaft, of an automatically-adjustable jack mounted thereon and disposed in a normal horizontal position, said jack including in its organization a shaft at its extremity farthest from the power-shaft and having motion transmitted thereto from the saidl power-shaft, andadapted to be taken therefrom to other mechanism, and weight-controlled levers movably connected to the extremity of `the jack having i the motion-receiving shaft therein.

2. The combination with a line-shaft having a' driving-pulley thereon, of a horizontally-disposed jack movably attached to the said shaft and supporting a shaftwith power receiving and conveying pulleys in connection therewith, the power-receiving pulleys having motion imparted thereto from the driving-pulley-on the line-shaft, a counterof the jack opposite that attached tothe lineshaft and suspending' devices adjustably attached to the extremity of the jack to which the counterpoise mechanism is connected.

3; The combination with a shaft,'of a jack having. one .extremity movably connected thereto and supported in a horizontal plane and having mechanism to receive and transmit driving power, and suspending-rods engaging the extremity of the jack farthest from said shaft.
