TO ALL WHOM IT MAY CONCERN:

Be it known that I, ELIPHALET S. SonIPrn'nE, of Brooklyn, Kings county, New York, have invented certain new and useful Improvements in Carriage-Tops, for the convenient mode of constructing, handling, mang g, and governing the same; and I do declare the following to be a full, clear, and correct description of my said invention, reference being had to the accompanying drawings, making partof this specification, and to the letters of reference marked thereon, in which---- 7 Letter X shows an oblique elevation of the whole seat and top.

Figure 1 shows a side elevation of the inner disk of the female half of the main'or bow-joint, with its standard or base.

-Figurefl, the same view of the male half of the same. Figure 3, an edge view of the male half, with its horizontal belt or shaft passing through. Figure 4, a fiat view of. one-half ofan extonsion-joint. v Figure 5, a side elevation of the handle-nut to the main joint. In the drawings, likeparts of the invention are designated by the same letters of reference.

The nature of my invention consists in the use or employment of circular frict ionsurfaccs, constructed. as

hereinafter described, for the purpose of raising, lowering, controlling, and securing a carriage-top in the varione forms. and positions required.

To enable those skilled in the arts to make and usemy invention, I will describe it, as follows:

Letter X shows a plain carriage-seat, upon each arm or end of which are secured the main bow-joints, when the parts A B, B 2', and G G are combined, letter a,'the back or main how, (as being attached to the outer surface of the male or revolving wedge-circle,) and represented as having been turned back flat down; at, the middle how, and a 2' 2', the front'bow, the two being elevated and secured in position by means of the joint E and H, having been extended, and thus secured by means of tho thumb-screwF.

To drop the bbws a 2' and a c' 2', turn backward thumb screw F, when they may be dropped entirely, or partially, and there secured firmly by drawing together the fruition-disks A and B by means of tliurnh-screw F. When the whole top is elevated, the main or baekbow is held in position by means of the handle screw-nut, letter D, being screwed upon the shaft G O, as shown at D c', in letter X, where also may be seen the two connecting bow-straps i and j, which connect and secure the three bows together, (or four, if that number is used.)

The main or back bowie firmly sustained and held in place by means of the powerful cohesive attraction of the wedge-surfaces, as a substitute for the outside back braces on an ordinary carriage-top, which how has also to sustain the other portion of the top in its position, to which main or back bow is attached one end of the joint-brace E and H, while the other end is attached by pivot to the front how a i z. The said braces E and H may he used by placing one at each side of the top, or a single one at the top, to eifect the extension. thereof.

The advantages possessed by my present invention are- First. Simplicity and small cost of construction, in view of the many and important results derived therefrom.

.Second. Greater strength, when properly made.

Third. The readiness with which the whole top may be taken oil" and again replaced, and I Fourth. That the folds may be readily placed and firmly held at any chosen point, while being operated from inside, thereby quickly laying back the front bows while another person gets into the seat, and as readily replaced thereafter.

Fifth. By means of the main bow-joint A and B, the greaterportion of the weight of the bows and top may he sustained, without resting wholly upon an arm or horn, therebypreventing all jouncing, rattling, and chafing.

Sixth. That the main bow-joint may he set upon the seatrarms, with the bows either inside or outside, allowing the handle-nut D to do its office on either side, convenient to be got at while sitting inside, while at the same time presenting facilities for ornamentation either inside or outside.

Claim.

Having thus described my invention, what I claim as new, snd desire to secure by Letters Patent, is not the circular corrugated wedge friction-surfaces as when made by themselves, as the same has been made by me, and described in mypatent, dated January 7, 1868, for compasses, calipers; 860.; but

I wish to claim their application, as described, when combined with a carriage-seat and top, substantially I in the manner and for the purposes set forth.
