POSTIONING MEANS FOR ADJUSTABLE SUPPORTS.

Original application filed February 1, 1913, Serial No. 745,696. Divided and 1913. Serial No. 772,598. l

To all 'whom t may concern Be it known that I, PETER A. SOLEM, a citivZen of the United States, residing at Cincinnati, in the County of Hamilton and State of Chio, have invented certain new and useful improvements in Positioning Means for Adjustable Supports, of which the follow-l ing 1s a specification.

lvly invention relates to positioning means for adjustable supports, and is especially applicable to the support or housing which supports the horizontally disposed cutterliead in wood planing machinery Aarranged to operate on the upper side of the stock. I have shown and described my invention in Yconnection with suoli housing, it being understood that said horizontally disposed cutter-head may be the sole cutter-head in the machine, or other cutter-heads operating for instance on the bottom o-r on one or more edges of the stock may be employed.

It is the object of my invention to provide new and improved means for positioning a support of the character mentioned, Whereby said support is clamped simultaneously and to equal degree Vat all clamping points for insuring maintenance of adjusted positions of the support; and, further, to so construct and arrange the guiding means and so relate the clamping means theretor in novel manner as toy cause maintenance of kadjusted relation of the parts; and the invention will be further readily understood from the following description and claims, and from the drawings, in which latter:

Figure 1 is an end elevation of my improved device shown in connection with so much of a wood planing machine as is necessary to illustrate my invention. Fig. 2 is a plan view of the same. Fig. 3 is a rear elevation of the same; and, Fig. 4 is a detail in section on the line 4 4 of Fig. 3.

11 represents the main frame, partly Specification of Letters Patent.

Patenten Nev. a, i913.

this application led June 9 n ent instance supports a rotaryl cutter-head 13 and achip-brealrer 19 therefor, mounted 1n suitablemannen The support is adjustable up and down on the guides 13.l This u support, shown as a cutter-head housing, has guideways therein cooperating with `said guides. The guideways are formed by rabbets at the respective ends of the housing,

these rabbets each having a bottolifwall 21 having a fiat bottom guide-face 22 and an end wall 23 having a flat end guide-face 24, the end guide-face 24 being perpendicular tO the flat bottom guide-face 22, plates n n 25 being secured to the end walls 23 by For effecting the sliding movement of the support, screw-rods 31 are threaded into threaded lugs 32 on the support,the screwrods being j ournaled and held longitudinally stationary in bearings 33 in the main frame. Each of the screw-rods has a bevelgear 34 secured thereto. 35 is a cross-shaft j ournaled in bearings 36 in the main frame and having bevel-gears 37 fast thereon, the bevel-gears 37 meshing with the gevel-gears 34. f The cross-shaft has a turning means thereon, shown as a squared end 38 adapted to be received in the squared socket of a suitable wrench, for turning Vsaid cross-shaft and thereby turning said screw-rods and adjusting said support upV and down.

After adjustment the support is clamped,y in place by Vclamping means whichk exert clamping stress in'fdirections at right angles to the opposed parallel clamping faces clamped, for clamping the Opposed walls of they guideways and the guides at the respective ends of the support toward one another in directions perpendicular to their parallel clamping faces so as to Obtain a clamping agency exerting clamping `force over considerable area in such manner that the clamping action will avoid disturbance of adjusted `i'elation in the parts. I prefer to eti'ect the yclamping :by clamping the guides between the bottom walls 21, which are rigid parts of the support, `and the plates 25 which have suilicient resiliency toL Vwalls 21 of said guideways and pass through slots 44 in the guides. A` set-nut 45 and a jam-nut 46 are screwed about the outer threaded ends 4'( of each of said clampscrews.

ri'Curning means are provided for each oit the screws, shown in each instance in'the form of an arm 48 the hub 49 of which has spline-connection with the clamp-screw for turning the clamp-screw upon swinging movement of thearm, but permitting relative axial movement between the clampscrew and the hub ot the arm. This splineconneotion is shown accomplished by a key 50 in the clamp-screw received in a splinegroove 51 in the hub.

The arms at the respective ends of the adjustable support are connected by links 52 having articulations with said arms at 53 for causing simultaneous movement of the clamp-screws at the respective ends of the support.

I further prefer to connect the clamping means atthe respective ends of the support, which I have shown accomplished by means of arms 54 extending from the hubs'of the upper ones of the arms 4S, the armsi54 being connected by a link 55 articulated therewith by articulations 56. The arms 54 preferably have hand-grips 57 thereon arranged to be grasped for clamping or unclamping the adjusted support from positions at either side of the machine. The upper arms 48 and the arms 54 form bell-crank levers.

By means of my improved device the ad justed support will be clamped in adjusted: position after adjustment without disar; rangingthe adjustment, and the adjusted support may be released 'to any desired extent for providingV a looseor comparatively tight .sliding iit'between said guide and guideways, as may be-desired for the purpose kof adjustment. It further provides means whereby the clamping strain acts upon faces of the guides and guideways which extend inplanes at right angles to the axesiof the clamp-screws, whereby "endwise or other displacement `of the 'adjusted support is prevented in the clamping operation, which is especially desirable in that it prevents disarrangement of the supported operative agency, exemplified as the cutterhead, with relation tothe stock-support or other operative portion of themachine. My improved device further provides means whereby the clamping action of each clampscrew may be adjusted, so that all of the clamping means may exert equal clamping action simultaneously, thereby aiding in avoiding disarrangement of the adjusted part.

Having thus fully described my invention, what I claim as new and Letters Patent, is:

1. In combination, a supporting structure having laterally outwardly extending guides at the respective ends thereof extending up and down, each of said guides comprising opposed parallel guide-faces, and an adjustable support provided at each end thereof with aguideway having opposed walls andan end wall, said guideways opening toward each other with said guides received between said opposed walls and said end walls received outside said guides, said opposed walls provided with opposed parallel guide-faces parallel with and coperating with said first-named opposed parallel guide-faces, and a plurality of interconnected clamping means between said opposed walls'respectively comprising connecting members between said opposed walls which are perpendicular to all said opposed parallel guide-faces, and constructed and arranged for simultaneously exerting clampingstress between and perpendicular to said cooperating opposed parallel guide-faces, for the purpose described.

2. In combination, a supporting structure having laterally outwardly extending guides at the respective ends thereof extending up and down, each of said guides comprising opposed parallel guide-faces, and an adjustable support provided at each end thereoil witha guiding rabbet comprising a bottom wall and an end wall, said walls rigid with said support, and a resilient guide-plate secured to each of said. end walls, said bot-tom wall and said resilient'guide-plate provided with opposed parallel guide-faces parallel with and coperating'with said i'irst-named opposed parallelguide-faces, and a plurality of interconnected clamping means respectively comprising connecting members betweenisaid bottom walls and resilient plates passing said llaterally,outwardly extending guides and perpendicular to all said opposed parallelguide-faces,and constructed and arranged for exerting clamping stress between and perpendicular to said -coperating opposed parallel guide-faces, for the purpose described.
