COMBlNED'S-ASH RATCHET AND PIVOT.

SPECIFICATION forming part of Letters Patent No. 695,161, dated March 11, 1902.

Application filed July 15, 1901.

To all whom it may concern.-

Be it known that I, JOHN G. LINKERT, a citizen of the United States, residing at No. 228 South Henry street, in the city of Dayton, county ofMontgomery,and State of Ohio,have invented certain new and useful Improvements in a Combined Deck-Sash Ratchet and Pivot; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part' of this specification. 7

My invention relates to improvements in combined deck-sash ratchets and pivots for hanging semicircular, oval, and other forms of transom-sash in the decks of railroad-cars and other places; and its object is to so construct an automatically-adjusting ratchet and pivot as to permit of the same being applied to and operated in connection with a variety of forms of transoms or deck-sash, thus avoiding the necessity of special construction for each particular form.

The invention is designed to be an improvement upon the device shown and described in United States Letters Patent No. 237,973, issued to Hart and Bissell, February 22, 1881, and which device is not adapted to the various curvatures of sash to which my improvement is applicable and which fulfils the requirement of a pivot-plate, having a sulficient surface to permit of its screw-fastenings entering the wood sash a sufficient distance.

apart to insure proper rigidity.

My invention consists in forming the pivotplate in two parts, one of which is formed rigid, preferably integral, with the pivot arm or bracket, the other being pivotal] y attached thereto at the upper end thereof and capable of being secured to the sash at any desired angle with relation to the said pivot arm or bracket, the purpose of which, together with details of construction, being hereinafter more fully described, and pointed out in the claim at the end of this specification.

In the accompanying drawings, forming a part hereof, Figure 1 represents a deck-sash, curved at one end and straight at the other,

mounted in its frame by means of the hereindescribed device. Fig. 2 represents a vertical cross-section through Fig. l and shows by dotted lines the sash open in two positions. Fig. 3 shows a broken perspective view of the device in operative position, but detached from the frame and sash. Fig. 4 is a perspective view of the pivot-bolt and its case; and Fig. 5, a perspective View of the pivot, its segment, and means by which it is secured to the sash.

In the said drawings similar letters of reference indicate corresponding parts in all the figures.

A represents the sash; B, the frame; 0, a pivot-plate adapted to be attached to the outside of the sash, at each end thereof, by screws or other suitable means. I This plate O is provided with a projecting arm or bracket D, extending from said plate and terminating in a curved line, with a laterally projecting pivot'E as its center, the said curved line being serrated, as shown, and having at one end an extended portion a to form a stop for the bolt when the sash reaches its limit of travel in opening. The pivot-plate 0, arm D, pivot E, and stop a are by preference formed in one piece.

F represents a plate provided with a seat or bearing 1), in which the pivot E journals. This plate is provided with perforations c d e to receive screws by which it is secured to the frame, as shown in Fig. 1, the perforations (1 and e being slotted for a purpose presently to be described, and it is also provided with a casing O, which operates a bolt H, movable through the ends of the casing and having bearings therein, as shown in Fig. 4,

the lower end of said bolt being rounded or beveled to permit of its free operation in the serrations formed in the arm or bracket D. This bolt II is provided within the casing with a projection I, which serves the purpose of a bearing for the lower end of a spiral spring J, which surrounds the bolt, and also acts as a stop to limit the movement of the bolt when released from engagement with the arm or bracket D, and being parallel with the side of the case permits longitudinal movement and prevents turning therein. The upper end of the spring J bears against the upper inner end of the case. Consequently there is a constant downward pressure of the bolt H, which when in operative position holds the bolt under pressure in one of the flutes of the serrated arm D and the pivot E in its seat or beari'ugb. An auxiliary plate K is pivotally connected at f to the pivot-plate O, the purpose of which will presently appear.

It is very important that the sash be so hung as to close tightly against the frame and be held firmly in such position. To accomplish such result, it is necessary to locate the fixture a considerable distance above the bottom of the sash, the actual distance being governed by the width of the sash. Moreover, as there is considerable strain on the fixture when the sash is being opened and closed a substantial means 0E attachment must be provided, and it is better that the points of actual attachment be both above and below the pivot upon which the sash is hung, which with my improvement is permissible, as the pivot can be located at the proper place on the sash without regard to its curvature and the auxiliary plate K can be so adjusted as to permit of its being securel y fastened by screws or bolts to the sashrail, as clearly shown in Fig. 1. It will be clearly seen that should the plate 0 be extended beyond the serrated extension of the bracket D a sufficient distance to receive screws which could not otherwise conveniently be inserted such extended portion of said plate would project over the sash and there would be no wood to receive the screws; also, that the plate would then prevent the sash from closing. It will therefore be seen that with my improvement the pivot-plate can be made of suificient length to provide ample bearing-surface on the sash without projecting over the same and that its pivoted portion K can be set at such angle to the rigid portion 0 as the curve of the top sash-rail may necessitate, that it can be securely fastened thereto at points where there is the least danger of splitting the wood by screws or bolts by which it is secured to the sash, and

that the fixture can be applied at the proper elevation to cause the sash to close tightly and with sufficientleverage to retain itin such position.

Semicircular and other forms of curved deck-sash are rapidly coming into general use in railway-cars, and much difficulty has been experienced in hanging the same with fixtures of the general character described herein, and in order to provide a pivot with a plate having sufficient bearing on the sash to insure the necessaryrigidity and permit of the screws or bolts being located a sufficient distance above the pivot to form durable fastenings which will amply resist the strains incident to the operating of the sash it has heretofore been necessary to make special patterns to suit the various curves of sash, while with my improvement the fixture is adapted to sash which are square at their ends or which are curved to any form, and by reason of this fact the fixtures can be kept in stock and used 011 any form of sash desired, which is a great convenience and saving of cost to the car-builder.

It is apparent from the foregoing description of my invention that the sash can be held in either of the positions shown in Fig. 2 of the drawings.

I disclaim the invention set forth in said Patent No. 237,973, and

Having thus fully described myinvention, I claim as new and desire to secure by Letters Patent- In a deck-sash ratchet and pivot, a pivotplate provided with an auxiliary plate in pivotal connection therewith, a serrated arm and a pivot, in combination with a plate having a pivot-seat and a spring-actuated bolt en gaging the said serrated arm, whereby such engagement will hold the sash in either of several positions, as required.

In testimony whereof I hereunto subscribe my name this 13th day of-July, 1901.

JOHN G. LINKERT.
