TRANSOM LIFTER.

JOSEPH MORITZ, 0F DRESDEN, GERMANY.
TRANSOlVI-LIFTER.
Specification of Letters Patent.
Patented Oct. 8, 1912.
Application led September 12, 1911. Serial No. 648,828.
To all whom 'it may concern:
Be it known that I, JOSEPH Monrrz, a sub ject of the German Emperor, and resident ot Dresden, Germany, have invented eertain new and useful Improvements in rlransom-Litters, of which the following is a specification.
The present in vention relates to improvements in transom litters which are operated through the medium of a rotary axle, and it consists in that on the latter one or more eccentric disks are located, which, upon lifting the transom, disengage the locking hooks by means of lateral pins, while chain wheels are arranged, which are separated 'from each other by the width of the transom and by which through the medium of chains, which are suitably guided, the closing movement ott the transom is etl'ected until the same is locked by the locking hooks.
In the accompanying drawing, Figures 1 and 2 are respectively a front View and sectional side view of the improved ar angement, while Fig. 3 shows a detail ot same in a side view.
The axle 1 is revolubly mounted on brackets 2 and 3 having bearings thereon. On one side of said axle a chain wheel L is keyed, over which the endless chain 5 is led, which at the lower end is led over an adjustable toothed wheel. Beside the chain wheel, two other chain wheels 6 are located on the axle 1, which serve to move the chains 7 holding the transom. The chain 7 is by bolt 8 fixed on a lug 9 screwed on the transom. The locking device consists ot' a closing hook 10, which is adapted to move on a bolt 11 fixed in the lug of the bearing 3 and to be depressed by means of a spring 12. Vhen closing the skylight, the closing hook 10 snaps over a lug 13 fixed thereon and thereby locks the transom closed.
On the axle 1, an eccentric disk 14: is fixed, which, when turned, lifts the closing hook 10 and presses the transom away from its frame. The transom is pivoted by means ot hinges 20, the pivot 17 of which can be removed in a manner well known in the art tor lowering the transom. Then the transom is opened by means ot the disk 14 by pulling the handle oit chain 5, it is, if de sired, further opened by a spring 1) so far that it will turn over by its own weight except as held by chain 7. i
For opening the transom, as already mentioned a handle ot the chain 5 is pulled` whereby the axle 1 and thus the pin, which is fixed on the disk 14, is turned. Said pin lifts the closing hook 10, while at the same time the disk 141i opens the transom by action ot' spring 19. By a 'further pull on the handle oit' chain 5 the transom can be turned down 'for an angle ot about 160.
For closing the transom, the chain 5 is moved in opposite direction, the action heilig then the same as above described but vice versa.
To entirely lower the transom, the pivots 17 ol. hinges 2O are withdrawn and the chain 5 is somewhat attracted, whereby the lower end ot' the transom is lifted trom its hinges. Upon the chain 5 being then moved in the required direction,- the transom moves down as far as permitted by the length ot chain 7.
I claim:
An improved means for operating hinged transoms, comprising in combination a rotary axle mounted on the frame oli' the transom on top of same, lugs on the transom, springpressed closing hooks on the ,trame ot the transom adapted to engage said lugs in the closed position o the transom, eccentric disks on said axle having lateral pins de signed, upon rotation oit said axle, to disengage said hooks from said lugs, a hand chain gearing to rot-ate said axle, and holding chains on the transom to guide the same when being opened, substantially as de' scribed and shown.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
JOSEPH MORITZ. Witnesses PAUL Anims, CLnn SIMON.
