SPECIFICATION forming part of Letters Patent No. 542,998, dated July 23, 1895.

Application filed January 15, 1894- Serial No. 497,013. (No model.)

Be it known that I, HENRY MIDDLETON DINNING, a subject of the Queen of England, and a citizen of the Dominion of Canada, residing at Montreal, in the county of Hochelaga, in the Province of Quebec, Canada, have invented a certain new and useful Device for Releasing Oar-Window Springs, of which the following is a full, clear, and exact description.

Thisinvention relates to an improvement in devices for withdrawing or releasing the springs of car windows, blinds, 860.

The object of the present invention is to provide a simple, inexpensive, and efficient device applicable to any railway passengercar, whereby the springs or catches which uphold car windows and blinds in raised position may be withdrawn separately or one at a time and each independently of the other from beneath the lower edge of such window sash or blind for permitting the latter to be lowered, thus avoiding the inconvenience and annoyance incident to the deflection of said springs or catches by means of the finger or the'point of an umbrella or cane or other handy article. 7

Other objects and advantages of the invention will appear in the course of the subjoined description.

The invention consists in the combination, with a window-casing provided with two or more grooves for the reception and guidance of the window sash and blind or blinds and with two or more self acting springs or catches adapted to rest normally in the path thereof, of a transversely-extending crankshaft provided with crank-arms extending in opposite directions therefrom and disposed in different planes to correspond with the planes in which the self-acting springs or catches are located, and means whereby said crank-shaft may be manipulated for withdrawing one or the other of said springs or catches from beneath or out of the path of the sash or blind, said springs or catches being connected with the crank-shaft in such manner that either one may be operated independently of the other.

The inventionalso consists in certain novel features and details of construction and arrangement of parts, as hereinafter fully described, illustrated in the drawings, and finally embodied in the claims.

In the accompanying drawings, Figure 1 is a perspective view of a car-window, looking from the interior of a car and showing a pair of self-acting spring-catches attached to the casing, showing also the thumb-piece or finger-grip for operatin g the crank or rock shaft, the latter, together with the connecting chains or links, being shown in dotted lines. Fig. 2 is an irregular vertical section taken through the window-casing, showing the relative arran gement of the spring-catches, crank-shaft, and connections thereto. Fig. 3 is a detail view of the crank-shaft and thumb-piece or finger-grip for operating the same, said figure being shown partly in'section to illustrate the connection between the shank of 'the thumb-piece and the rock-shaft.

Similar numerals of reference designate corresponding parts in the several figures of the drawings.

Referring to the accompanying drawings, 1 designates a pair of the ordinary and wellknown spring-catches employed in railwaycars for the purpose of upholding the sashes and blinds of the numerous windows. These spring-catches are made usually from strips of flat spring-brass, being riveted at their lower ends within the grooves or rabbets formed in the adjacent inner faces of the Vertical sides of the casing, thenpp'er ends being bent inwardly toward and passing into recesses or apertures in the window casing or frame, thus forming horizontal shoulders and at the same time providing for the deflection of said spring-catches inward against the easing and beyond or outside of the path of the window sash and blind.

It will beunderstood, of course, that the grooves or rabbets in which the window sash and blind respectively move must necessarily be located in different vertical planes, and that, as a result, the spring-catches will also of necessity be arranged in correspondinglydifferent planes. The usual method of throwing said spring-catches out of the path of the window sash or-blind in order to lower the latter is to force the desired catch inward by sirable, as where the spring is very stiff the finger maybe bruised or injured in theattempt. In order to overcome this diificulty and to manipulate either the one or the other of said spring-catches in an easy and convenient manner, I provide a short transverselyextending crank-shaft 2, which is preferably arranged just outside of the side bar of the window frame or casing, to the inner face of which the spring-catches are applied. This crank-shaft may be supported in bearings in any desired or preferred manner, and is provided with two or more crank-arms 3, extend ing from opposite sidesthereof and in opposite directions, said crank-arms being formed preferably integrally with their shaft and for the purposes of carrying out this invention, being disposed in different planes, or, more accurately speaking, in the same vertical plane with the respective spring-catches with which theyare connected. 'lheconneetionsbetween the crank-arms and the spring-catches may consist either of links 4 or chains 5, or both, as indicated in Fig. 2, so long as said connections are flexible, and thereby adapted to operate through their respective openings or passages in the window frame or casing.

In order to facilitate the application of the herein-described device the crank-shaft is provided in its inner end or thatend which faces toward the interior of the ear with a square or polygonal socket, into which the shank 6 of the thumb-piece or finger-grip 7, having the same cross-sectional shape, is adapted to fit, thereby adapting the crankshaft to turn with the thumb-piece or finger-grip. In order to retain the thumbpiece in place and prevent the withdrawal of its shank from engagement with the crank-shaft I provide a collar 8 surrounding a reduced portion of the shank of the thumb-piece and screw orotherwise fasten said collar to the inner face or wall ofthe carspring-catches, either one of said springcatches may be deflected and withdrawn from the path of its respective sash or blind for permitting the same to be lowered. It will also be apparent that by locating the crank-arms in different planes upon the crankshaft or at different points longitudinally of said shaft,

so as to correspond with the different planes in which the spring-catches are arranged, a direct pull is given upon each spring-catch, and each one of the catches is capable of being operated independently of the other.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is

1. The combination with the frame or cas ing of a car window and with two or more spring catches arranged within the path of the window sash and blind, of a crank shaft suitably mounted upon, or adjacent to the window frame or casing, said shaft being provided with crank arms extending inopposite directions therefrom and disposed in different planes or at different points 1ongitudi-' sitely extending cranks disposed in different planes corresponding to the planes in which the spring catches are arranged, a thumb piece or finger grip adapted to pass through the casing and having a squared or polygonal shank engaging a correspondingly formed socket in the adjacent end of the crank shaft, and a retaining collar surrounding a reduced portion of said shank and secured in place by suitable fastening devices for preventing disengagement between said shank and the crank shaft, substantially as and for the purpose specified.

HENRY MIDDLETON DINNING.
