Serial No. 629,106.

To (all whom it may concern:

Be it known that I, I'IEMAN OSBORNE, a citizen of the United States of America, and resident of Springfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improve ments in lransom-Lifters, of which the fol lowing is a full, clear, and exact description.

This invention relates to improvements in transon'i operating devices of a type such as is exemplified in Letters Patent of the United. States granted to me June 11, 1901, No. 856,288, and one having the respective functions of such a device. But the present invention is for the purpose of providing a transom operating mechanism which, due to the improved organization thereof is capable of the fulfilment of its functions more efliciently and satisfactorily, and which by reason of its simplified character is less costly of manufacture and assemblage, and is-less liable of derangement after protracted use and is generally of greater acceptability in the trade.

The principal features of improvement and advantage in the present device are found in the means whereby the wormwheel carrying shaft, having the transom operating lever like member permanently fixed thereon, and radially extended therefrom, may be revolubly adjusted relatively to the worm mechanism so that the transom operating member may have all required capability for positioning 01' adjustment to accord with transoms which may be more or less deeply set in the casings, and all as hereinafter fully explained; in the arrangement of the springs operatively employed for counterbalancing the weight of the opening transom, and the means for varying the tension or reaction of the springs to insure proper counterbalancing action with respect to transoms of different sizes and weights; and in the new arrangement or combination of the parts for the requirement of extreme simplicity cheapness and operative efficiency of the device.

The invention is described in conjunction with the accompanying drawings and is set forth in the claims.

In the drawings: Figure 1. is a front elevation of the transom operating device with the cover portion of the casing removed. Fig. 2 is a vertical sectional view through the same on the line 2-2, Fig. 1. Fig. 3 is a horizontal cross section on line 3-3, Fig. 1. Fig. t is a perspective view showing the operating device as applied in its operative relation to an under pivoted or hinged transom. Fig. 5 is a perspective view of the rear portion of the casing as seen from the rear. Fig. 0 is a perspective view of certain of the principal parts of the novel device in separated relations. Figs. 7 and 8 respectively are sectional and face views indicat ing the manner of the permanent connection of the transom operating member with the rotativc carrying shaft thereof. Fig. 5) is a view of one of the counterbalancing springs employed in the device. A

Similar clmracters of reference indicate corresponding parts in all of the views.

In the drawings, A represents the supporting frame of design and dimension having fitness to its purpose, and B reprcscl'lts a shaft rotatively ll'lOlllllOCl in the frame and carrying at its one end which extends outwardly beyond the frame and its inclosing casing C, the lever-like member D which is operatively connected with a slotted bracket E affixed on the transom in a manner common in devices of this kind.

The end portion of the shaft is made with a flange-like enlargement a which includes a squared portion b and a shoulder If fitted to which is the butt end of the transom operating member D which is permanently held in place by the screw 0 and retaining washer 0 The middle portion of the shaft B has the screw threads (I thereon and other portions of the shaft toward the opposite ends thereof are made with the right and left screw threads f, f, as shown in Figs. 3 and 6. The worm-wheel F is screw engaged on the threaded portion (Z, at the middle of the shaft, whereby the shaft is rotatively adjustable within, and relatively to, the worm-wheel for revolubly adjusting the transom operating member B so that such member may reach its engagement with the fixture E of the transom irrespective of whether the latter is much or little inset within the casing.

Tt will be here explained that in the employment of the device the frame, which is inclosed by the casing C and which supports the mechanism, is generally secured on the face of the door casing about as represented in Fig. 4-,--the lever-like arm D extending upwardly to proximity with the transom which it, such arm, engages through the medium of the slotted bracket or transom fixture E. Inasmuch as in different sltuations the reveal varies, that is in some forward relatively to the face of the casing, it is necessary to make provision whereby the lever-like transom-operating arm may be revolubly adjustable about the axis of the shaft B so that it will have its range of movement for forcing the transom open or closed within whatever space maybe requisite according to the conditions under which the transom and the casing are set.

G G represent a pair of arms having apertured shanks which embrace the shaft B at opposite sides of, and closely alongside the worm-wheel F, the same bein engaged with the worm wheel so as to have revoluble movements in unison therewith by the engagement in the sockets g in the arms of the studs 9 which extend from opposite sides of the worm-wheel.

J J represent a pair of ring-nuts screw engaged on the right and left threaded portions f f of the shaft and servln both to confine the shanks of the arms G 6} against the opposite faces of the worm-wheel and to lock the worm-wheel and shaft in their revolubly adjusted relations.

as a fixed part thereof, a sprocket wheel L around which runs the intermediate part of the sprocket chain M, through means of which the device is manually operated to the coils thereof loosely encircling said bar and having their extremities 10 and 12 extending angularly from the bar and in angular relations to each other as best shown in Fig. 2.

Duplicated links 1% m connect the extremities 1O 10 of the springs y' with the hookshaped ends of the arms G; and the screwplugs 0 0 engaged through an upper front portion of the frame have tension varying engagements with the adjacent extremities 12 12 of the springs so that by turning the screw-plugs inwardly the reaction of the springs is increased to accord with large or heavy transoms while the forward turning of the screw-plugs decreases the spring reaction.

Vhen it is desired to vary the normal direction of the extension of the radial leverlike transom operating member D relatively to the axis of the shaft B it is only necessary on the removal of the front section of the cover or casing to loosen one or the other of the nuts J and swing the member 1) which is screw engaged with and permanently connected to, the shaft, so that the shaft may be rotated, as much as desired, it being understood that the threaded part (Z at the middle of the shaft when both of the nuts are not set up against the opposite faces of the worm wheels, is free to have a rotative movement relatively to the worm wheel, which will remain stationary by the inworm K.

Almost the entire mechanism of the transom operating device, including the means for the adjustment of the shaft, is inclosed, concealed and safeguarded within the casing; and as none of the parts of the operative mechanism especially including those for effecting adjustments are visible or acing' the parts thereof properly positioned indefinitely continued and eflicient service without liability of derangement. be also stated that the operating chain the middle of which has a supporting engagement around the sprocket wheel, and the depending portions of which terminate at about the same distance below the casing, under the capabilities hereinabove described for the adjustment of the shaft, undergoes no change relatively to the sprocket wheel when'the arm carryin shaft may be adjusted. preparatory to setting up the device and after the chain has been assembled in relation to the sprocket wheel.
