VIIIIPROI'ED LINK-JOINT FOR GAR-SEATS'.

TOALL WIIQM IT MAY GONCERN: V

Be it known that I, ROBERT HITCHCOCK, of Springfield, Hampden county, Commonwealth of Massachusetts,

have invented a. new and useful Improved Link-Joint forA Car- Seats and I do hereby declarethat the following vis a full and exact description thereof, reference being had to the accompanying drawing, and to the letters of reference marked thereon. In the drawings- VFigure l represents a side view of my invention applied to a. car-seat, and L Figure 2 a detailed view of the same. This invention consists of a new and simple joint for the link of 'a car-seat, wherelit is connected with ther back of the scat, serving fo'r` the same either way the back is'turned. v l

l In construction I'form my joint ot' a piece, A., of malleable iron usually, which may be screwed upon 'the edge of thecar-seat back, as is shown in fig. 1. A socket is formed into this piece, at a convenient part of it,

for the, end of the link B to he attached in. It is in the peculiar constructionof this socket, G, that my invention lies principally, the object of this invention being to make a. joint which shall he very strong, vund yet not cumbrous. l A

i In most all of thejoints now in use there is a.l twisting strain upon the pin connecting the link with the ear,

owing two the pressurevof the seat backwards aswell as downwards. This is nlso `very much increased at the.

moment of turning the seat over, when the jar is very apt to 4break out the pin, which in my device is'repriwV sented by E. To ohviate this, I form my socket, Gr, so that the downward and outward pressure of the seat does not bring any Vleverage against the pin`E, but relieves the latter, the edges of the end of the link B hearing against the inner edges above, and below, of the socketGr. Thus, in fig. 2,it is seen that on each side of the pin E, above and below, the width of `the socket is about the same as that of the end of the link. From these two m points, however, it tapers each way, so that in front and rear it is much wider thanin the centre, where tanda approach towards each other. In this lit is also shown tha-t thetop back edge, b, of the socket rests upon the top edge'otf the end of the link, and the front bottom edge of the socket, -c, bears against the lower edge of the end of the link, thus taking'a-ll strain, except the direct one backwards from the link.

This device can be made much cheaper than the ordinnry ones inV use, andrnay be covered up or attached outside to the edge of the car-seat, inthe latter' case making an ornamental instead of bungling appearance.

Now, having described my invention, what I claim as new, and desire to secure by Letters Patent, isA

A link-joint for car-seats, in which the end of the link B is pinned in a socket, G, the latter havingits top and bottom edges tapered each way froma central point in line with the pin E, substantially as is herein shownv and described'. t
