Fio. 13 isa Side elevation of mechanisn similar to that shown in Fig. 1v, but partially folded (or extended).

Fig. 14 is a side elevation of mechanism similar to that shown in Fig. 1, but in the full folded position.

In Fig. 1, 1 isvthe body of the vehicle,

having 'a wind shield 2. Rotatably mounted upon a bearing, fixed in the body l, is the gear casing 3, Within which is journaled the stub shaft 4, having a square recess 5, for the reception of a crank. Projecting above the gear casing 8, and integral therewith, is

c the arm 6, having straight track portions, 7

and 8. Axially positioned within the arm 6, is journaled a threaded shaft 9, engaged by nut 10. This nut 10, has projecting ears 11 and 12, to which are pivoted, respectively, the links 13 and 14, on the respective pins 15 and 16. Journaled upon the pins 15 and 16, are rollers 17 and 18, positioned to engage the respective track portions 7 and 8, to carry directly thereon any stress coming from the links. 13 and 14, and thus relieve the shaft 9 of said stress. The arm 6, terminates in a fiat head 19, to the upper portion of Vwhich are pivoted link 20, on the pin 21, and link 22 on the pin 23. Also pivoted tothe head 19,7is a slotted link 24, having the angular slot 25, through the outer end of which the pin 26 passes, in sliding engagement therewith. 27 is a bent link pivoted by the pin 28, to the link 22, and also pivoted by the pin 29, to the link 14. rlhe short arm 30, of the-link 27, has fixed thereto, an ear 31, upon which is pivoted a pawl 32, having a form and position adapted for engagement with the elbow 83, of the link 24, during the angular movement of the links.

Pivoted by the pin 34, to the outer end of link 14, is a bent link 35, the shape of which is such as to conform to that of links 22 and 27, when the links are in folded position. The link 36 is. pivoted by the pin 37, to the link 27; and the link 38 is pivoted by the pin 39, to the link 36. The link 40, is pivoted by the pin 41, to the link 85. Links 35 and 36 are pivoted by ein 351. Links 14, 36 and 40, are preferably made of two parallel members, spaced for balancing the construction and for Vthe free angular movement of the other links, pivoted thereto.

' Returning new to the head '19 of the arm 6; the link 13, in the normal open position of the top frame, is preferably horizontal, Which necessitates pivoting` the links 13 20 at varying distances, respectively, rfr m the pins 15 and 21, and the angular movement of these links during the operation of the top frame necessitates the positioning of the pin 42, within a slot 43, in the link 13. To the outer end of the link 13, on the pin 44, is pivoted the cross yoke 45, havin@ a coil spring 46, adapted to throw yoke to have 'ts plane in line with the axis of the link 13, when the band portions 47 and 48 become limp, in the movement of the top frame. This construction of cross yoke 45, with its attachment to the link 12), is made for the purpose of having these members automatically adjustable to the requirenients of the respective folding positions of the links. A. similar set of swinging arm and links, with gear casing, ete., to that just described, is mounted on the opposite side of the vehicle, and the two sets are connected in the i'following way: rhe cross yoke, 45, is pivoted to a link similar to link 13. rllhe swinging arm 6, and its duplicate, are fixed to a cross yoke 419, by screws 50 and 51. The link 14 and its duplicate, are pivotally connected to cross yoke 52, by the pins 53. Link 86 and its duplicate are connected to the cross voke 54, by the pins 55. lThe outer ends of the links 40, are connected by the cross piece 56, to which is attached a securing device 57, adapted te `secure the outer end of the top frame to the wind shield The cross yokes, 45, 49, 52, and 54, and the cross piece 56, are connected by parallel bands 58. which are fixed at the point 59, to the rear of the body l. A hanger 60, is provided as an outer support for the links in their folded position.

Referring to Fig. G. the gear casing 3, is shown attached to the remaining part of the gear casing by screws 79 and 71. i

Referring to Fig. The central. position of threaded shaft 9, with respect to the arm (3 is shown. VEhe track portions 7 and S are also shown.

Referring to Figs. 8 and 9, the gear box 63 is shonf'n fastened to the wall 1, of the au-` toinobile body. Also fastened to the said wall plate 7 2, attached by bolts, 7 3 and 7a. This plate 7 is an extension of a bearing 753, fixed in the wall of the said body 1, :for the purpose of journaling the tubular portion SCL, of the casing The shaft el. entends Within the gear box G3, and has fixed thereto, the gear 7 6. To a screw shaft, 77a, which is fixed in the plate 79, is journaled the gear 77, which meshes with the gear 76. Fixed to the gear 77 is smaller gear 7S. The screw shaft 79, which is fixed in the plate 72, has jonrnaled thereon a large gear 80, which meshes with the gear 7 8. Fixed to the gear 80 and concentric therewith, is a gral therewith.

The outer `part 3 of small gear 81, lwhich meshes with the circular rack S2. The circular rack 82 is inadc part of the extension 3ft, of the gear casing 3, so as to rotate with the gear casing 3, and the arin 6.

Referring to Figs. 10 and 11, the tubular extension 3", of the gear casing 3, is shown journaled in the journal box 75, which is attached to the Wall of the vehicle body l. The gearing construction Within the casing Si similar to that shown in Fig. 9. Fixed upon the wall of the vehicle body 1, a circular rack 83. The plate Si is integral with the inner end of the tnbnlar portion 3f* of the gear casing 3, and revolves with it on the journal .box ele. Fixed to the shaft 4: is the gear 85. A plate 8G, is provided and spaced from the plate Si, and connected therewith by the screws 87, SS, and S9, upon which are journaled the following gears: On screw S7 are 'journaled the two gears 90 and 91, the gear rnf-ishing with the gear S5; and the gears 90 and 91, being `fixed together. .lour- .naled upon the screw S8, are the gears and 93, which are fixed together, the gear 92 meshing with lthe gear 91. Journaled upon the screw 89 are the gears and 95, which are lined together, the gear 9i meshing with the gear-93, and the gear 95 meshing with the stationary rack 83.

Referring to Fig. 11, the relative align laiI positions of the arni il and 'the plates Si and 8G ir'itli the rack 83 are shrnvn.

Referring to Fig. 123, one end of the eros.` yoke i5 is shown, haring a bracket i5 inte- The pin il is shown passing through the bracket elo", and the en tension i5, of the cross yoke 45, and 'journals the link 11:) with the yoke ln between the bracket i511 and the extension 1115, is the sjgiring 46, having1 one leg 13, thereof, bearing upon the link 13, and another leg 45", thereof, bearing upon the bracket 45s. Projecting freni the cross yoke i5, is the lug and, which acts as a stop for the enter cud. of

the link 13, to limit its position to the plano of the cross yoke -il-, to be normally in line with the axis of the link 13.

ln operation, referring to Figs. 1 and lil, in Fig. 1, the top` franie is in extended position, we will say, about to be folded. The top frame is released at the securing device 57, from the `Wind shield FZ. The crank si, shown in Fig 5 and G, is inserted in the re cess 5 of the stirb shaft 4i, and as it is turned, both the shafts it and 9 are rotated, through the intern'iesliing of the Oears GS and (i9.

Referring to 8 and 9, the resultant action of the turning of the shaft i 'to cause the rotation ofthe gear casing 3. The

gear 76 rotates the gear 77, and the gear 78 rotates the gear S0, the gears 77 and 78 being fixed together'. Gears 80 and S1,being fixed together, the gear 80 rotates, and haw ing a` permanent axis of rota-tion with re- -rotate upward about its pivot point spect to the body 1, it causes the circular rack 82 to turn; which being' fixed with the tubular extension 3a, of the gear casing 3, causes an angular movement of the arm 5 attached thereto. By the meshing of the gear 68 with the gear 69, thev rotation of the crank 1 is eonnnnnicated with the shaft 9, which turning within the nut l0, causes same (if rotated in the right direction) to travel downward, along the arm 6, carrying with it the links 13 and 14 (see Figs. 1 and 13) and continuing downward until some such position, of the nut 10, is reached, as is shown in Fig. 13; during which movement the link 27, is turned about the pin 2S, as a fixed axis, and the outwardly extending links connected therewith, are caused to move through a comparatively low path. If new we continue to rot-ate the crank 4b, in the same direction, causing further downward movement of the nut 10, the pawl 232, having come in contact with the elbow 33, of the slotted link 24, will cause the link Q4 to gib, until the pin 26 is moved downward to engage the long port-ion of the slot 25, and the further movement'of the nut 10, brings into an angular action, the previously russed link 22, permitting the folding together of the parts, as is shown in Fig. 14, until they rest upon the hook 60. During the travel of the nnt10, along the arm 6, the band portions 47 and 4S have become limp, and the spring 46, shown in Fig. 12, becomes free to throw the cross yoke 45 into a position having its plane in line with the axis of the link 13, and remains there during the further movement of' the nut 10, drawing the links int-o the folded position of the frame shown in Fig. 14.

An alternate form ofl mechanism used for angularly positioning arm 6, is shown in Figs. 10 and 11, and operates in the following way: The plates 84 and 86, in which are positioned the screws 87, 88, and 89, acting as shafts'for the gears, are fixed upon an extension 3a, of' the gear casing 3, and rotate therewith. The shaft 4 being fixed to the gear 85, which meshes with the gear 90, rotates the same, as well as the gear 91, fixed thereto. The gear 91, meshing with the gear 92, rotates the same, as well as the gear 923, fixed thereto. Gear 93 rotates the gear 94, as well as Vthe. gear 95, fixed thereto. The gear 95 being in mesh with the fixed circular rack 83, forming a track upon which the gear 95 rolls, carries with it the plates and 86, which rotate about the axis of the shaft 4a, which rotation is communicated to the gear casing 3, fixed thereto, causing an angular movement of the arm 6. I preferably provide a complemental set of' gear mechanism for the opposite arm 61, of the top frame.
