l F. E. TAPLING. AUTOMATIG SASH AND TRANSOM GENTER.

Pateted Au 24, 1909.

FRANCIS E. TAPLING, OF BUCYRUS, OHIO.

AUTOMATIC SASH AND TRANSOM CENTER.

Specification of Letters Patent.

Patented Aug. 24, 1909.

Application filed April 1, 1909. Serial No. 487,164.

To aZZ whom 'it may concern:

Be it known that I, \FRANCIS E. TAPLING, a citizen of the United States, residing at Bucyrus, in the county of Crawford andState of Ohio, have invented a new and useful Automatic Sash and Transom Center, of which the following is a speoifioation.

The Object of the present invention is to provide an improved construction of sash or transom pivot.

More speoifically, it is the Object of the invention to provide a transom pivot which will, act to hold the transom in any desired position to which it is swung, and the invention further aims to provide means for positively holding the transom against moving past position to close the Opening in which it 1s mounted, except of course in one direotion.

In the acoompanying drawings, Figure 1 is a view in side elevation of the pivot embodying the invention. Fig. 2 is a vertical sectional view therethrough on the line 2-2 of Fig. 1. Fig. 3 is a perspective view of one of the members of the pivot. Fig. 4 is a Similar view of the looking pivot or swivel, and Fig; 5 is a similar view of the other one of the two pivoted members of the device.

In the drawings, the device is shown as oomprised, broadly speaking, of a pair of pivoted or swiveled members one of which carries a looking swivel having elements engaging with the other member to hold the two members at various angles with respect to each other, and of the members, one is indicated in general by the numeral 10 and the other by the numeral 11, both of the members including a comparatively thin web or intermediate portion 12 and abutments 13. These abutments 13 of each member are two in number, one located at each end of the web or intermediate portion 12 and the said abutments of each member are off-set laterally one with respect to the other so that when the members are pivoted or swiveled, as when assembled between a transom and its frame, and the members are so relatively turned with respect to each other as to close the transom, the corresponding abutments of the two members will mutually engage and prevent further movement of the transom in that direction.

As is clearly shown in Fig. 3 of the drawings, the member 10 is formed upon the inner face of its web portion 12 with a stud 14 and with notches 15 which radiate from the said stud and receive looking elements upon the looking pivot or swivel as will be presently explained. It will further be observed from an inspeotion of the said Fig. 3 of the drawings, that the abutments 13 are flush with the outer face of the member but project beyond the inner face thereof and the same is true of the member 1 1 as will be seen from an inspection of Fig. 5 of the drawings.

The member 11 of the device, as far as it has been desoribed, is identical in its construction with the member 10 except that instead of the stud 14 and notches 15, it is formed with a socket 16 which projects from its outer face and opens through its inner face and which is formed with an extension 17 of less diameter than the socket itself, and through the end of this extension with an Opening 18. The said end of the extension is quite thick and is formed transversely with a slot 19 in a plane transecting the Opening 18. Disposed within the socket 16 is a looking swivel having a head 20 and a stem 21 which projects into the extension 17 and through the Opening 18 thereof, the said stem being formed transversely with an Opening 22 through which is engaged a pin 23 seating in the slot 19, it being understood that the head 20 and its stem extension 21 are held by the engagement of the pin in the slot, against rotative movement with respect to the member 11 by which they are carried. Engaged upon the stem 21 of the looking swivel is a s ring 24 which bears at one end against the c osed end of the socket extension 17 and at its other end against the inner end of the head 20, this head being formed upon its outer end face with a plurality of lugs 25 which extend radially with respect to the axis of the head and from a socket 26 which is formed in the said head 20 for the reception of the stud 1 1.

It will be observed from the drawings that the notches in the member 10 and the lugs upon the outer end face of the head 20 of the looking swivel are triangular in cross section, so to speak, and when the two Sections 10 and 11 are assembled as in Fig. 2 of the drawings, it will be understood that the said lugs 25, of which there are preferably several, will engage in the notches 15 and will be held in such engagement by reason of the tension exerted by the spring 24 against the head 20 to move the same toward the member 10, this movement being of course limited prior to the assembling of the members by the engagement of the pin 23 in the slot 19 in the end of the socket extension 17. It will further be understood that upon relative rotative movement of the two members 10 and 11, the lugs Will successively engage in the notches 15 until the transom is open to the desired degree and in which position it Will be held by reason of such engagement of the lugs in the notches.

It Will be understood of course that the members are applicable in any manner desired to the transom and its frame or in other words that the member 10 may be applied either to the transom frame or the transom itself and also the member 11 may be arbitrarily applied.

What lS claimed is In a deviee of the class deseribed, coperating relatively movable members, one of said members being formed With a pivot stud and seats eXtending radially from said stud, the other member being formed With a socket and With an Opening aXially of the socket and Opening into one end thereof, the said member being further formed With a slot in a ,plane transecting the Opening, a head pivoted in the socket and provided With a stem projecting into said Opening, said head being further rovided With teeth engaging the seats in t e first mentioned member, a spring disposed upon the stem and normally holding said head With its teeth in the said seats, and a pin carried by the stem and having its ends projecting into the said slot.

In testimony that I Claim the foregoing as my own, I have hereto aflixed my signature in the presence of two Witnesses.

FRANCIS E. TAPLING.
