- TRANSOM-OPERATING MECHANISM.

I Specification of Letters Patent.

Application filedOctober 14, 1918. Serial No. 257,951.

To all whom it may concern v I Be it known that I, CLARENCE VICTOR JONES, a citizen ofthe United States of America,and resident of 230 ,Yonge street, city'of Toronto, county of York, Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in Transom-Operating Mechanism, of which the-following is a specification.

The invention relates to improvements in transom operating mechanism as described in the presentxspecification and illustrated in the accompanyingdrawings that form a part of the same. Y Y

The invention consists essentially of the novel means employed for controllingthe movement of a transom against pressure adapted to-hold same normally to an open position. y

The objects of the invention are to eliminate annoyance and inconveniencein adjusting transoms located out of "reach of the operator, to p-rovidea means for guidingthe operatingchain in its movement thereby facilitating the adjusting of the transom and generally to provide an operating mechanism for transoms and the like which will be neat and pleasing in appearance, inexpensive to manufacture, simple to operate, durable and efficient.

In the drawings Figure 1 is a perspective view of a transom held to an open position by means of the present invention.

Fig. 2 is a diagrammatic view in vertical section through the guiding mechanism for the operatingchain and the catch for said chain.

Fig. 3 is a vertical sectional view through a closed transom and frame and taken substantially on the line AA of Fig.1.

Fig. 4 is a front view of the housing for the chain guiding rollers with said rollers shown in dotted lines.

Fig. 5 is a detail of one of the spring hinges employed to hold the transom normally to an open position.

Fig. 6' is a detail of the catch employed to hold the operating chain to anydesired position.

Like numerals indicate corresponding parts in the various figures.

Referring to the drawings the transom 1 is provided with one or more reverse hinges 2 secured to the outer side thereof and to the frame 3 and adapted to exert pressure to hold said transom normally to an open position (the construction of said hinge being more fully described and claimed in another application) 4 is a bracket secured to the inner. side of the sash and having its end turned out- Patented Mar. 18, 1919.

wardly at right angles and projecting 1 slightly past the edge of the frame 5.

The mowement of the transom is controlledby means of a chain 6 secured at one end to the bracket 4 and operating through a guiding device mounted onthe frame 5 substantlally opposite the bracket 4 and through a catch .7located below said guiding device. The housing for the chain guiding spools conslsts of a substantially rectangular box 8 adapted to be countersunk in the frame 5,

vexed considerably forming an enlarged lower portion 11 and then being turned inwardly at right angles and slotted as at 12 and projecting outwardly in a flange 13, said flanges 10 and 13 being provided with suitable openings to accommodate screws 14 for securing the housing to said frame 5.

The top 9 is provided with a chain slot 15 located directly behind the outer end of the bracket 4 when the transom is in its closed position.

16 and 17 are the chain guiding spools rotatably mounted on shafts 18 transversely arranged in the housing 8, the spool 16 being positioned in the upper portion of said housing and the spool 17 being positioned in the enlarged portion 11 and considerably in advance of said spool 16, said spools being spaced from one another substantially the thickness of the chain 6.

The chain 6 is secured at its upper end to the bracket 4 and extends through the slot 15, around the rear of the spool 16, over the front of the spool 17 and out through the opening 12 from where it extends downwardly through the opening in the upper end of the catch 7 and into the slot 18 in the front wall of said catch where it is held against the pressure of the spring hinges 2.

In the operation of the invention when it is desired to open the transom it is simply necessary to pull outwardly on the lower end of the chain 6 and immediately upon the disengagement of said chain from the slot 18 the hinges 2 will force the transom open, the chain in the meantime traveling freely over the spools 16 and 17. When the transom has opened the required distance the chain is simply pushed back into the slot 18 thus preventing further outward movement of the transom. To close the transom the chain is simply disengaged from its slot and pulled downwardly and again placed in its slot. 7

The employment of the chain guiding spools located in their housing in a direct line with the chain catch and directly behind the bracket from the transom provides for a straight pull on the transom thus giving a freedom of movement which is not obtained with the employment of the devices heretofore known.

What I claim is 1. In transom operating mechanism, in combination, a transom provided with a bracket having its end projecting over the frame thereof, guide mechanism mounted in said frame adjacent to said bracket, said guide mechanism consisting of a pair of spools positioned one above the other, the uppermost of said spools being countersunk in said frame and the lowermost spool being adapted to project a considerable distance beyond the face of said frame, a chain secured to said bracket and operating over said spools, a housing for said guide mechanism and a catch mounted on said frame below said guide mechanism for locking said chain.

2. In transom operating mechanism, in combination, a transom adapted to be spring held normally to an open position, a bracket secured to said transom and having its end projecting over the frame thereof, chain guide mechanism mounted in said frame adjacent to said bracket and consisting of a substantially rectangular housing counter sunk in said frame and having the lower portion of its face conveXed and projectingoutwardly from the face of said frame and slotted, a pair of spools transversely mounted within said housing, one above the other, the lowermost of said spools being located within said convexed portion, a chain secured to said bracket and projecting through an opening through theface of said housing and extending over the rear of the upper of said spools, around the front f the lowermost of said spools and emerging through said slot and a catch for locking said chain.

Signed at the city of'Toronto, Ont, this 9th day of August, 1918.

CLARENCE VICTOR JONES.
