up and its more uniform support; the shift ing of the top forward when down and backward when up; the shifting of the front bow to elevate it when the top is up in order to provide convenient access to the front seat; the more convenient attachment and release of the forward main bow in .both raising and lowering the top; and other objects which will hereinafter fully appear. To these ends my invention consists in top-supporting hinged branches for the upper ends of the main-bows; an adjustable top-shifting connect-ion whereby the top may be moved forward or back relatively to the body; a continuous joint or link connection for shifting the front bow; a novel releasable fastening in connection with the forward main bow; and other details of construction, arrangement and combination which I shall hereinafter fully describe and claim.

Referring to the accompanying drawings, Figure 1 is a side elevation of my vehicle top, showing it in raised position, the dotted lines indicating it shifted forward when lowered.

' Each main-bow is divided or, split at its upper end into two branches, the branches of bow 2 being designated by 2' and those of bow4 by 4. The branches are separately hinged at their lower ends to the main bow, so that they may diverge when the top is up, and lie parallel in alinement with the maln bow, when the top is down. Their function when the top is up and when they lie in divergent planes or spread out, is to furnish a greater supporting surface for the top throughout its length and prevent sagging, so that the weight is well divided and a uniform sweep of the top from front to back is had. They avoid the extra weight of a five-bow topa-nd give in effect a six-bow top on four bow sockets. These split bows have a further advantage in connection with the top-shift which I shall presently describe. These branches of the main Hows may be hinged in any suitable manner, A

reliable and efficient construction for hinging them is as follows: The upper portion of each main how has a wood core designated by 7, and this fits down into the socket of the bow proper. To this wooden core is fastened the legs 8 of a hinge piece, the head of which -is formed with the knuckles 9. To these knuckles are pivoted the plates 10 to which the bow branches are secured. The lower end of the rear main bowf 4 is fitted with the socket bend 11, which is provided with a rear ear 1L2, a front ear'13 and a bottom ear 14. To the rear car .12 is pivotedthe socket bend 15 of the b ack bow 5.

To the bottom car 14 is pivoted one end of the top-shifter bar 16. This bar may be either a straight one or a curved one. It is supported and has its swinging movement in a channeled base 17 secured to'the bracket 17 on the vehiclesbody. This base lower guard flange, 18, and an upple flange 19, between which the top-s ifter bar normally lies, said bar being pivotally connected with the base by a pm 20 which in has a threaded end on which is seated has a r guard thumb-nut 21. does not project: as far as the lower guardflange 18, so that a spring which is titted on the pin 20 and. bears against the shit or bar 1t), normally tends to force the bar side wise against the lower guard flange, in which position it is clear of the upper guard flange and may, therefore, be swung through a vertical are about the pivotal pin 20, forward or. back. The thun'ilrnut 2]. however, when tightened up draws the bar well in and holds it firmly seated between the two guardllanges; but when said nut is loosened, the spring again clears the bar from the upper flange, and said bar is then free to be swung about its pivot forward or back.

The object and eli'cct of this construction are as follows z-ll hen the tt'orward main bow with its attached front how are freed from the front connection and brought back and said forward main bow is pivoted to the front car 13 of the socket bend ll of the rear main how i, and the top is properly collapsed, the branches of the main bows then coming together parallel, all the bows lie substantially parallel on one another or in such bow-holder as maybe provided, and the top projects in this folded condition rearwardly of the body. Now by loosening the thumb-nut 21 thereby freeing the bar 16 of its base 17, as heretofore described, said bar may be swung forwardly through a vertical are about its pivotal center 20, and thereby the whole top will be bodily carried or shifted forwardly, a distance equal to twice the length of the bar 16, that is, a distance equal to the length of sweep of said bar. The advantages of this forward shift of the top when down are that there less overhanging leverage, and the top takes up less space at the rear of the vehicle, permitting the latter to occupy less room in the garage. Further advantages of this shil't in connection with the split or branched bows are that a neat, and cornpact pacleige may be made of the folded top, and also that when the top down the curvature of all the bows is nearly alike on accoiuit of the split: bows having greater length when closed, than the ordinary bows usually provided for tops, the result being that the distance from the back of the vehicle body to the inside of the bows is practically the same with all of them. This advantage is utilized to draw the top closer to the rear of the body by means of the shifter bar. When the top is lifted again, the shifter bar is thrown back to its first position and thereby restores the top to its full extent.

If the shifter bar be a curved one, as

shown by 16, in Fig. 2, there may be had the additional advantage especially applicable to small tops, that he entire top when closed may be shifted downward-and rest The upper guard-flange 19 l at any desired angle without unfasteningQ illlS I have indicated in said Fig. 2.

To enable one to conveniently get into and out of the front seat of the vehicle, sonic tops are inside with a shiftable front how, the connnon practice being to have a bracket on the upper portion of the forward main bow in which when the top is up, the front bow is fastened by means of a cotter pin, thereby lifting said front bow high enough to give convenient. access to the front seat. When the top'is to be lowered, the cotter pin is removed and the tront bow is-shifted down again to the lower end of the main bow and again fastened by a cotter pin. Instead of this detachable construc-. tion which takes time and is difiicult to manage, I have a continuous connection or joint which results in the necessary shifting of the front bow. 23 is a link which at one end is pivoted to the lower end of the front bow At its other end it is pivuted to a bracket 2 l'on the forward main: how 2. This link has side flanges 25 to steady it on the main bow, and said link is concaved more or less on both faces to adapt it to fit snugly both bows.

\Vhen the top up, the bow shift link 2? lies against the main-bow and rises from its pivotal bracket connection therewith'at 21 to its pivotal connection at its upper end with the lower endof the front bow. Thus the latter bow is shifted upwardly high enough to atl'ord convenient access to the frontseat. When the top is being lowered, the front bow moves down, the shifting link 23 then turning away from the main bow and downwardly about its pivotal connection with said main lrow, until it is reversed end for end and then lies against and between both bows, thus lowering thelower end of the front bow through a distance twice the length of the link, and bringing it down to ,its proper position near the lower end of said main-bow. Thus the connection is a continuous one between the two bows and the shifting'ofthe front bow is effected by the swinging of the link With the usual tops, in raising them, the forward main bow with its attached front how is released from the car 13 of the rear l main how, by removing a. cotter pin from the short belt of the bow which fits said ear/and then pressing the bolt out of the ear. Then the bows are carried forward and the short bolt of the forward main bow is inserted in a hole in the forward goose-neck or iron on the vehicle-body and a cotter pin passed through the bolt. This unfastcning and refastening is a slow process, as the points of the cotter pins spread more or less and-"do not lit the holes evenly. On some pins the points are too close, or the holes are too large, which results in the pins jumping from their proper positions on account of the vibrations of the vehicle. Also because the points stick out beyond the bolts they very often tear ones clothing. To provide a more efiicient fastening, I have the following device. In the lower end of the forward main-bow is fitted athumb bolt 26, which has on its-inner end the key-lugs 27. The inner face of the head of the goose-neck or iron 28 on the front of head of the goose-neck 28, the thumb bolt 26 is turned so that its key lugs 27 aline with the channels 30' of said head. Thereupon the bolt is passed through the goose-neck head, and when its key lugs emerge therefrom, the bolt is given a quarter-turn, andreleased, whereupon the spring presses it out and causes the key-lugs to enter and look within the grooves 29 on the inner face of the goose-neck. To release the parts, the thumb bolt is pushed in slightly, its spring yielding until the key-lugs are free of the grooves and then by turning the bolt, the lugs will aline with the channels 30 and the bolt can be withdrawn from the goose-neck. The same connection -is made for the forward main bow with the ear 13 of the rear main b by providing. said ear with the cross channels 13 in its aperture and with cross grooves 13 on its inner face. This fastening is simple and efiicient and will not work pivotally connected at one end to thevehicle .body,and at its other end to the lower end of the rear main bow, said bar being adapted-to be'positioned to extend in a horizontal position to the rear of its pivot, and when 1n said position to support the bows in raised posltion, said bar being adapted to be swung to a horizontal position in advance of its pivot to shift the lower ends ofthe, connected bows relatively to the vehicle body when the top is lowered.
