LOCK PROP-JOINT FOR CARRIAGE-TOPS.

SPECIFICATION forming part of Letters Patent No. 522,476, dated July 3, 1 894. I Application filed February 9,1894. 7 Serial No. 499,674- (No model.)

My invention relates to a lock prop joint for buggy tops.

One of the objects of the invention is to so construct the prop joints of the buggy top that they may be arranged on the inside of the curtains so as to be raised and lowered readily.

Another object of the invention is to lock the prop joints in position when raised so that they cannot be thrown back accidentally.

Another object of the invention is to provide means for having the projecting joint near the top pass outside ofthe top and between it and the curtain, avoiding all danger v of the joint wearing the top.

It is I impossible to arrange the ordinary prop joints of carriage tops so that they may be placed inside of the curtains because when the top is folded back the joints come in contact with the top and either punch a hole or soon wear the lining out. My invention obviates this difficulty besides making a superior prop joint, the various features of which are fully set forth in the description of the accompanying drawings making a part of this specification, in which Figure 1 is a side elevation of my improvement applied to a buggy top with the curtains removed. Fig. 2 .is a side elevation showing the same folded. Fig. 3 is a top plan view of one form of lock for the lower joint. Fig. 4 is aseetion on line an, ac, Fig. 3. Fig. 5 is a modification ,of Fig. 3. Fig. 6 is a section on line y,y, Fig. 5.

A represents the body of the buggy; B, the seat; 0,.the seat rail; D, the central and main bow; E, an inclined bow. The two are hinged to the rail 0 by the usual form-of joints (1.

My prop joint consists of three sections, F, G, H, which are arranged as follows: Section F is connected to the seat railCby the joint b. 0 represents a knuckle joint hinging section F to section G. (1 represents an ordinary pivot on which section G swivels. e represents a knuckle joint hinging section G to section H; section H is secured to the valance bow.

' As shown in Figs. 3 and 4 the look for the joint consists of the catch gand the latch lever, h, which is secured to section F by pivot 2. When the latch lever 71. is engaged in the catch as shown in fulllines Fig. 8, and in section Fig. 4, the joint is effectually locked so that it cannot be broken or turned.

When it is desired to let the carriage top down the latch lever h is thrown round into the position shown in dotted lines, Fig. 3. And then the prop joints can'be readily folded back in the position shown in Fig. 2.

Any form of lock applied to the joint may be'employed. I have shown one other form as a modification which consists in the slide K shown in Figs. 4 and 5; said slide is provided with the slot 111., and the slot n at the end of said slide.

0, 0, represent rivets passing through the section F and held in position by the washer plate P which rests on the top of the slide and allows it to slip freely. In order to guide the slide I insert a block 4 in the slotm, removing the sides of the slot from contact with the rivets 0, 0.

s representsa rivet with an enlarged head 8 riveted so as to engage over the adjacent sides of slot n, thereby holding or looking the slide in the forward position. r

o representsa knob. on slide K to allow it be readily moved back and forth, the friction of the engaging parts will hold it in position. It is shown in the locked position in Figs. 5 and 6, in which position it bears firmly against the pivot ends of sectipns F and G, and holds the joint locked. It can be readily slid back free of the section G and the parts will then fold into the position shown in Fig. 2.

I do not Wish to limit myself to any par= ticular form of lock joint except where the same is made a feature of the clauses of the claims herein.

In order to allow the upper joint 6' to. pass outside of the top M, I prefer to make the studs 1), d, which form the bearing of the joints longer, and bend the section II out, as indicated by the shaded lines w. The upper joint 8 will then pass outside of the hood or carriage top M, thereby avoiding all danger of injury to the same when folded down.

Several advantages are obtained by the features of my invention; first, the top can be readily raised and lowered from the inside; second, it can be locked firmly in the raised position; third, the top folds in a better shape and is less liable to injury than by the usual form of folding carriage tops. The ordinary concealed prop joint between the bows D, E, is indicated by dotted lines R.

Having described my invention, what I claim is- 1. A prop-joint consisting of the sections F G lying inside of the curtains and connected by the hinged joint 0, the outwardly bent section H hinged to the front valance bow and to the section G, and a locking device over the joint 0 between the sections F and G, whereby the top may be raised and lowered from the inside, substantially as described.

2. A prop-joint consisting of the section G swiveled to the central bow D, the upper ontwardly bent section II jointed at one end to the front valance bow and at its other end to the section G, the lower section F hinged to the seat rail and jointed to the swivel section G inside the curtains, and a device for locking the joint 0 of said sections F and G, substantially as described.

3. In combination with a central vertical ward to throw the upper joint e outside the top while the lower sections of the prop-joint are inside of the curtains and adapted to be operated from the inside of the carriage, substantially as described.

4. In combination with the carriage top hows, the prop-joint consisting of the section G swiveled to the vertical bow D, the lower section Fhinged to the seat rail and arranged inside the curtains, the joint 0 between the sections F and G, a locking device adapted to be engaged with the lower faces of sections F and G and to be disengaged from one of said sections to enable the top to be folded, and the upper section II hinged at e to the swivel section G and connected at itsvother end with the valance bow, the said section II being bent outward in such manner as to throw the upper joint 6 outside the top and avoid injury to the top or its lining when the top is folded back, substantially as described.

In testimony whereof I have hereunto set my hand.
