Application filed November 25, 1922.

railroad car windows for the purpose of holding the window open.

Devices of this sort usually comprise a metal plate which has projecting from its rear face a pair of spaced ears that are perforated so as to afford journal bearings for a roclrshaft, and extending crank-wise from this shaft is a locking lug, and a spring is employed to normally throw said lug into engagement with notches or the like that are formed usually along the inside edge of the inner sashstop, and the release of the lu is effected by means of a pair of finger p1eces one of which isrigid with the plate while the other is in the form of a short crank rigid with the shaft and extending through an opening in the plate in proximity to the stationary finger piece. By pinching this crank-like member toward the stationary finger piece, the rock-shaft will be revolved against the resiliency of the spring element, and the locking lug will thereby be withdrawn from engagement with the notches aforesaid and the window may then be raised. As soon as the window is raised far enough the release of the cranklike member will cause the locking lug to automatically engage with an adjacent notch to thereby hold the window open. There are, of course, two structures like that above described, one at each lower corner of the window, and, in each instance, the plate is secured to the face of the sash, the latter being mortised so as to accommodate the parts at the rear'of the plate,

and also so as to bring the outer end of each plate flush with that portion of the face of the sash which adjoins the edge and is therefore within the inner sash stop.

From the above descriptionthenature of SASH HOLDER FOR RAILROAD-CAR WINDOWS.

Serial No. 603,368.

the structure to which the present invention relates will be clearly understood.

In quite a number of instances, devices like that above described, have been equipped with a locking lug that extends from the rock-shaft beyond the journal bearing, but an overhung lug of this sort is quite apt to be sprung or severely strained by rough usage which seriously interferes wit-h the proper functioning of the device, and accordingly the journal bearing has been built out so as to provide a shoulder closely contacting the upper surface of the overhanging port-ion of the shaft directly opposite the lug so as to withstand the thrust of the latter.

The strongest structure would, of course, be one in which the lug projected from the shaft intermediate the journals of the latter, and the present invention is in this category.

But, if the locking lug is positioned on the rock-shaft intermediate the journals it must be located very close to the journal that is adjacent the sash stop, for otherwise such lug could not engage the notches along the inner edge of such stop. This being so, and because the shaft is considerably longer than the distance between the innerfaces of the journal bearings, it would apparently be impossible to insert the ends of the shaft within the bearings.

The present invention aims to solve this difficulty and to thereby afford a structure of great simplicity and strength, and in this respectthe invention relates to the manner or method employed to bring about the result desired.

Figure 9 a section at the line Figure 2.

Similar numerals of reference denote like parts in the several figures of the drawing.

1 is a plate, usually of brass or bronze, having countersunk holes 2 whereby it may be secured by screws to the bottom of a window sash at the side edge thereof. A portion of this plate extends inside the general plane of the p-late'so as to form a jog 3, and when the plate is secured to the sash the latter is cut away or mortised to contain this jog so that the outer face of the latter is flush with. the face of the sash, and when the sash is properly assembled'between the usual sash stops, this jog 3 faces the inner edge of the inside stop."

The outer edge of this jog throughout a part of its length has extendii'iginwardly therefrom an car t. and the inner end of this ear is pierced as shown at 5 to accommodate one of the rOc'kshaftjournals as presently tobe described. When the plate 1 is secured to a sash, this ear 4 is mortised within the side edge of the sash so as to be substantially flush therewith.

' Opposite this piercing 5 the edge of the jog 3 is cut away'to form a recess 6 for the purpose presently to he explained.

7 is an ear extending inwardly from the plate 1 and integral therewith, and in this ear is formed a circular opening '8 that is in line with. the opening 5, these two ears 1 and 7 constituting the journal bearings for the rock-shaft.

The plate and ears are preferably cast in one piece.

9 is the rock-shaft, and 10 is the locking lug which is integral with said shaft and extends therefrom after the fashion of a crank and at a point spaced from the adjacent end of the shaft, and that part of the latter that is immediately beyond the lug 10 and which is specially designated by the numeral 11 is one of the journals of the shaft.

The opposite end portion of the shaft is of a reduced diameter as shown at 12, and adjoining this reduced portion is a squared portion '13 the-angular :part' of which extends heyond the "periphery of the portion 12 so as to provide shoulders whose function will presently be'noted.

This rock-shaft with its squared andreduced portions and the locking lug are preferably made integral by the drop-forging rocess, and the jonrnalsnf the shaft at each end are dressed off if-nec'essary.

The squared perti ou 1.13 has a diagonal diameter which is less than theidiameter of the niaiii portion ofthe rock-shaft,

as the distaneehetweenthe inner faces of the eats a and Ms much'less than thelength of the rock-shaft, and, as the presence of the lockingrlug at the point above noted would prevent the insertion of said shaft in its bearings by introducing it from the outside of either ear, the utility. of thereduced portions will be readily seen since it is merely necessary to initially insert the reduced portions at an angle through the orifice in the ear 7. after the fashion shown at Figure 8, and to thereafter push these reduced portions through said orifice until the opposite end of the shaft is in a plane inside that of the inner face of the ear 4, whereupon the shaft is straightened out and the journal 11 is then inserted in its proper bearing in the ear 4, and a bushing 14 is then driven tightly within the opening 8 and around'the reduced portion 12 so as to properly support said portion as a journal bearing.

After the rock-shaft has beenproperly located in its journals as above set forth, it will be noted that the locking lug extends fromsaid shaft into the recess 6 and this lug has an offset outer portion 15 the outside edge of which is substantially flush with the outside face of the ear 4, the plate 1 beyond the recess being shortened-so that the lug will have full play and be capable of projection beyond the plane -of the outer face 'of the plate. i

The inner edge of the ear 4: is preferably rounded as seen at 16, and the heel of the offset 15 is concaved as shown at 17 and bears against this rounded portion '16, so

that it will be clear that the thrust of the dog will be sustained by the ear 4.

This offsetting of the locking lug is quite essential since it positions the lug'directly opposite the inner edge of the inside sash stop and therefore enables the lug to function properly, and at the same time the structure possesses the great advantage of having the lug located at a point on the shaft that is intermediate the journals thereof.

18 is a finger piece formed rigid with the plate 1 and extending outwardly from the face thereof, 'and' 19 is a dog which projects through an opening 20 in the plate in proximity to the part 1 8, the inner endof which dog has a square opening 21 extending laterally therethroug-h and this end is driven tightly on to the'squared portion 13 of the rock-shaft as shown more particularly at Figure 4, so that it will he readily understood thatwhen a person places his forefinger beneath the part 18 and presses his; thumb down against the dog 19 the shaft will'be irocleedin a direction that will cause the-locking dog to he :moved toward the rear of the :plate 1.

.Acoil spring '22 .ar'o und the rock-sl1aft, and having one end-2-3 bearingagainst :the rear face "of 1 the plate .1' and with :the other loo lit)

end 24: secured to said shaft, normally revolves the shaft in a direction reverse to that caused by the depression of the dog 19, and therefore it will be obvious that the spring will act to normally keep the locking lug engaged with the notched inner edge of the inside sash stop, whereas the depression of the dog will release said lug and will enable the sash to be raised or lowered.

The coil spring 23 and the dog 19 are positioned on the rock-shaft before the latter is located in journal bearings as heretofore described, and, in this connection, it

; would be proper to state that the dog is initially driven on the squared opening of said shaft far enough to allow of the necessary insertion of the reducedv portions of the shaft through the opening 8, and thereafter said dog is properly positioned on said squared portion.

It will be observed that, when all the parts of the structure hereinloefore described have been properly assembled in a position for use, the abutment of the locking dog against the ear 4 and the abutment of the angular points of the squared portion 13 against the bushing 14:, will prevent any lengthwise displacement of the rockshaft.

Having thus described my invention what is claimed as new is:-

I. In a device of the character described, a base plate having spaced ears that are perforated, a rock-shaft having its extremities journaled within said ears and having integral therewith and extending radiallytherefrom intermediate said extremities a lug whose outer portion is offset so as to lie in a plane substantially coincident with the plane of the adjacent bearing.

2. In a device of the character described, a base plate having spaced perforated ears, a rock-shaft reduced in diameter at one end and formed intermediate its extremities with a squared portion, a locking lug extending from said shaft intermediate its extremities and having its outer portion offset so as to lie in a plane substantially coinciding with the plane of the adjacent bearing, said shaft being positioned by primarily inserting the reduced end at an angle through one perforation and thereafter inserting the other end within the other perforation to afiord one journal, a bushing driven within the first perforation and closely surrounding the reduced end of the shaft to afford the other journal, a finger lever having a hubwith a squared opening therethrough which hub is driven on the squared portion of the shaft, and a spring for normally rocking said shaft with the lug in looking position, said finger lever being operated to rock said shaft against the resiliency of said spring to bring the lug out of locking engagement.

3. A device of the character described, comprising a plate having spaced perforated ears, a rock-shaft journaled within said ears, and a locking lug carried by said shaft intermediate its journals and having its outer portion offset so as to lie in a plane coincident with that of the adjacent journal.

at. In a device of the character described, a plate having spaced perforated ears, a rock-shaft journaled at one end within one of the ears and at the other within a bushing driven within the perforation in the other ear, a locking lug carried by said shaft intermediate its journals and having its outer end offset to lie in a plane substantially coincident with that of the adjacent journal, said shaft having a squared portion, said lug and squared portion providing shoulders which abut respectively against the adjacent ear and the bushing to prevent lengthwise displacement of the shaft.

.5. A device of the character described comprising a plate having spaced perforated ears extending from the rear face thereof, a rock-shaft having a squared portion and a reduced end, the comparatively large end of said shaft being journaled within one of the ears while the reduced end is j ournaled within a bushing that is driven within the perforation in the other ear, and a locking lug carried by said shaft and extending therefrom at a point intermediate the journals of said shaft said lug being offset so as to lie in a plane substantially flush with that of the adjacent ear, while said lug and an angular portion of the squared part of the shaft act as stops to prevent lengthwise displacement of said shaft.

In testimony whereof I aflix my signature hereto.
