IMPROVEMENT IN TRANSOM-OPENERS.

Speeifioation forming part of Letters Patent N0. 190,1'76, dated May 1, 1877; applieation filed March 17, 1877.

T0 all whom z't mag; concern:

Be it known that I, JOHN F. WOLLENSAK, of Chicago, in the oounty of Oook and State of Illlnois, have invented a new and useful Improvement in Transom-Openers; and I do hereby deolare the following to be a full, clear, and exaot desoription of the same, reference being had to the acoorhpanying drawiugs, forming part of this speeifioation, in whioh- 1 Figure l is a front elevatiou, With a small broken seotion to show the transom-pivot. Fig. 2 is a horizontal sectionin line 00 w, Fig. l; and Fig. 3 is a horizontal seotion, showing the operation of the looking set-sorew.

Similar letters of referenoe in the 'aooompauying drawings denote the same parts.

This inventiou is an improvementupon the transom opening, shutting, and. looking devices for whioh three several Letters Patent of the United St2ites have beeh heretot'ore granted to me; and it consists, first in the peouliar construotion of the operating-rod; and, seoondly, in the novel look for looking the transom in 2t11ypositlou by the movement of the rod, substantially as I will now prooeed to desoribe.

In the drawings, T is the transom, of semioireular, square, or other form, hung upon vertical pivots tt ab the middle or lateral edge of the transom. D is the door, and C is the casing around the door and transom. Attaohed. to the oasing of the door is a long rod, R, oapable of sliding vertieally or partially rotating horizontally in three (more or lass) braoket-guides, g g q the lower one of whieh is provided with aset-sorew by whioh the rod oan be locked. .ii1 any desired posi- 'lhe upper end of the rod is oonueeted 130 the trausomby me ans of a o'rank-arm, 1, and conneeting-rod s, so that; by turning the rod the transom can be wholly o1 partially opened o1 closed, and oan be looked in any position by the set-screw. A smal-l pin, n, on the under side of the crank-arm or conneoting-rod registers with a hole or sei: of holes in a plate, m-attaohed to the frame of the door, so that by raising the rod the pin oan be raised out of any of the holes, and by 10W- ering it the pin can, when in proper position,

be dropped into any of the holes, and. the transom thereby doubly locked. Als the lower end ofthe rod R is a pendent handle, h, by

whioh to operate' the rod. for its various purposes.

in the plate, and, if preferred, sorew up the set-sorew.

Ilhe .set-sorew is designed to hold the long rod down so that the looking-pin oannot be raised from its sooket or hole from the Outside, and also, when the sash is opeu, to preventthe wind from swaying the sash backward or for ward.

This improved. devioe exteuding, as. it does, only to the lower part of the transom-sash,

oan be readily adjusted 130 any form of trausom, and, when oombined with the horizontally-swinging transom, the transom is perfeotly oontrollable by means of the rod, and is yet in 110 danger ofacoidentally fallling and breaki-ug the hinges or other parts, as is sometimes the oase with the verticall swinging transoms.

The devioe oan be made self-locking by inoliuing the end of plate m, so that the pin will, as the transom iS swung to a elosed position, strike the inoline and slide up 011 it and drop into the hole.

I elaim .as my invention 1. 'Ihe oombiuation of the rod R, the oraukconneotiou 1 s of the transom, and the vertioally-engagiug pin n and platze m, whereby the transom is looked or unlocked by the vertioal movement of the rod. and opened or olosed'by the partial rotation of the rod, substantially as desoribed.

2. The eombination of the rod R and orankoonneotion 1' s of the trausom, locking er unlooking by the vertioal movement of the rod, with the set-sorew at the lower endl of the rod, whereby the look is preventedfrom being operated from the outside, substantially as desoribed.
