HANSOMLCAB.

SPECIFICATION forming part of Letters Patent No. 611,385, dated September 2'7, 1898.

Application filed December 18, 1897. Serial No. 662,874. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH L. LAWRENCE, a subject of the Queen of Great Britain, re-

' siding at Boston, county of Suffolk, and State by hand, the ends of said shafts at the front of the .seat of the cab being provided with ball-like terminations which enter ball-sockets in links jointed, as shown in this instance of my invention, to the door-leaf of the lower hinge on which the door swings, said link in the movement of the door acting as a lever on the said hinge.

Instead of putting the closed window and frame in a pocket under the roof of the cab I have provided the edge of the windowframe with suitable roller or other sheaves which cooperate with an "1 shaped guidegroove, so that when said rolls are in the substantially horizontal part of saidgroove the window will occupy a substantially horizontal or closed position under the roof of the cab and when they occupy a position in the substantially vertical part of said groove the window will stand in itsclosed position, or in position to close the open front of the cab.

Figure 1 is a vertical section of the body of a hansom-cab embodying my present invention. Fig. 2 is a broken sectional detail looking into the front of the body, said View chiefly showing parts of the two doors and the means employed to open and close them. Fig. 3 is a detail to be described, showing the link connected with the door-hinge. Fig. 4 is a front view of the hinge alone. Fig. 5 is an edge view of that part of the hinge secured to the cab-body. Fi 6 is a section in the dotted line cc of Fig. 3 of the other half of the hinge. Figs. 7 and 8 are details of the link to embrace the ball-like end of the rock-shaft. Fig. 9 shows the ball-like end of said shaft. Fig. 10 is a detail showing a part of the outer face of the guideway for receiving the rolls or other studs attached to the window-frame. Fig. 11 is a cross-section of Fig. 10 in the line at. Fig. 12 is a detail showing the pintle or roll carrier detached from the window-frame. Fig. 13 shows the roller or other stud removed from the said pintle, and Fig. 14 shows the said roller in cross-section.

The body A of the cab, it having a roof A,

the doors A and the drivers seat A located I at the back of the cab-body, are and may be all as usual, as may also be the axle and running-gear to support the cab-body.

Underneath the roof A, at the sides of the cab-body, I have attached to the cab-frame two like suitable guideways composed of shaped slotted bars B, one portion of said guideways standing in a substantially horizontal position under the roof, the other portion being extended downwardly toward the seat and the open front side of the cab-body, as represented best in Fig. 1.

The window 0 has attached to each opposite side aplate O, (shown best in Fig. 12,) it having a pintle G on which is mounteda suitable roller or other stud 0 said roller being preferably composed of three parts-via, a divided hub 2 3 and the circular block or piece 4., the two pieces 2 and 3 being screwed together and embracing the part 4, the diameter of the part 4 being such as to substantially fill the space between the side walls 5 and 6 of the guide B, the part 0 of the pintle traveling in the slot 5 of the guide.

' The lower end of the space between the walls 5 and 6 at the front of the cab is so much contracted that when the roller 4. arrives in that end of the guideway, the window being then closed, the roller 4 will contact at diametrically opposite points firmly with the walls 5 and 6 and prevent any lateral back-and-forth motion or shaking of the window. In this way it is possible to prevent any rattling of the window when closed, and by making the central part of the roll O in the two parts as represented the body of the roll may be readily held and clamped. The part 4 of the roll will preferably be made of some non-metallic material, such as indiarubber or leather, or it might be wood.

The window has jointed to it at its upper and at its lower end a suitable strap, as (1, said strap being doubled, one branch passing over a roll 7 and under a roll 8,while the other passes over a roll 9 and under a roll 10. By pulling on one or the other half of this strap the window may be placed in the position Fig. 1 or it may be moved outwardly and downwardly to close the open front of the cab, the lower end of the window when closed entering the rabbet 13, cut in the stationary side of the cab, and a like rabbet at the top of each door. There are two doors to be opened and closed in like manner and simultaneously. The upper door-hinge d is and may be as usual; but the lower hinge cl is of peculiar construction, asI will proceed to describe, viz: This hinge is composed of two leavesviz., a leaf 14, which is attached to the door A and a leaf 15, which is attached to the rigid part d of the cab-body. The two leaves are united by a pintle 16, and the knuckle part of the leaf 15, which receives the pintle 16, is projected, as shown, wholly from one side of the leaf 15. (See Fig. 3.) The leaf 14 is provided with a suitable ear 17, having a shoulder 18 and a shank 19, the shank being inserted through a hole made in the leaf 14 until the shoulder meets the face of the leaf, and then a washer 20 is applied to the end of the shank 19 and the latter is upset, thus confining the ear 17 rigidly in place as a part of the hinge. This car carries the forked end (see Figs. 3 and 8) of a link 22, having at its opposite end a ball-socket 23, said ball-socket being completed by the addition to said link by suitable screws 24 of a cap-piece 25, h aving the other half 26 of the ball-socket. The

. face of the plate 15 of the hinge is provided with a recess 27, and said recess may-be inclosed on three sides, it being inclosed on its top and bottom sides by projections 28 29, extended backwardly from the plate 15.

Fig. 3 shows the hinge in the position it will occupy when the door stands nearly open, and to close the door the link 22 must be drawn upon in the direction of the arrow 30 and its socketed end must be swung around in the direction of the arrow 31 by reason of its connection with the freely-moving end 32 of the rock shaft E, mounted in suitable bearings E, and to enable this to be done the said link while it bears against the enlarged pintle-receiving portion of the plate 15 swings into the space 27 of the plate 15 as the door is closed.

Prior to this invention I am not aware that a hinge actuated by a link to close a door has ever had a recess in which the said link may enter as the door is closed.

The. plates 14 and 15 have suitable screwholes, as 35 to receive suitable screws by which to attach the hinge in position.

The rock-shafts E must be moved simultaneously to operate simultaneously the two doors A and to provide for this I have jointed with the arms 36 of the said rock-shafts, they being the arms which extend up at the back of the seat at the inside of the cab, each a suitable link 37, and the inner ends of said links are jointed to like levers 38, pivoted at 39 011 pivoted legs or struts 40, mounted on a block 41, attached to a rigid part of the back of the cab-body.

The contiguous ends of the two levers 38 enter a stirrup 42 and are pivoted in said stirrup by means of a stud 43, the said stirrup being made double and presenting a depending portion 44, suitably slotted to receive the upper end of a link 45, which is attached to the portion 44 by a, suitable pin, as 46, (see Fig. 1,) the lower end of the link 45 being jointed at 47 to the end of a lever 48, fast on a rock-shaft 49, having an attached hand-1ever 50, the said hand-lever being shown by dotted lines in Fig. 1 for the reason that it is located at the right-hand side of the drivers seat, and in the section Fig. 1 consequently the said handle would not show; but it has been added and is represented by the dotted lines.

Of course the handle could be put at the left-hand end of the shaft 49, provided the driver was left-handed.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A cab-body having separate slotted angular guideways secured within the cab-body, one at each side thereof, combined with a windowframe having devices cooperating with the said slotted guideways, and means accessible from the outside of the cab-body by which to move said window to open and close the same, substantially as described.

2. In a cab-body, angular guideways secured to the interior of the body, and a window-frame carrying at each side a plurality of roller-studs traveling between walls of the said guideways, the change of position of the rollers in the guideways determining the angular position of the window-frame, substantially as described.

3. In a cab, a cab-body having slotted guideways at its inner side, said guideways presenting walls 5, 6, which are contracted at the lower end of the said. guideways, combined with a window-frame having connected rollers traveling in said guideways, and, when the window is in position to close the front of the cab, fitting both walls of the said guideway, to thereby prevent any back-and-forth motion and rattling of the window, substantially as described.

4. In a cab, a rock-shaft having oppositelyinclined ends, the front ends of said shaft having ball-like terminations; links having sockets to receive said ball-like terminations; a hinge, a leaf of which is provided with an ear to which said links are connected, com

bined with means to simultaneously operate said rock-shafts, substantially as described.

5. In a cab, a rock-shaft having oppositelyextending ends, a link pivotally secured to the forward end of said rock-shaft, a hinge for the cab-door, the forward leaf of said hinge having an ear to which said link is connected, and the rear leaf of said hinge having a recess extending with an opening to the rear edge of said leaf, to receive and guide the adjacent portion of the link, substantially as described.

6. In a cab, means extending from the rear of the cab to the front thereof, and terminating adjacent the cab-doors, for operating said cab-doors, said means being movably secured to the sides of the cab adjacent said doors,

links connecting with said means at the for-.

ward extremities of the latter, hinge connections securing said doors to the cab, the forward leaves thereof having ears to which said links are pivoted, and the rear leaves thereof having recesses which open rearwardly to the rear edge of said leaves, and the hingeknuckles projecting in the line of movement of said links, to constitute fulcra over which the links must bear when moved by the operating means to close thedoors, substantially as described.

3o '7. In a cab, means extending from the rear of the cab to the front thereof, and terminating adjacent the cab-doors, for operating said cab-doors, said means being movably secured to the sides of the cab adjacent said doors, links connecting with said means at the forward extremities of the latter, hinge connections securing said doors to the cab, the forward leaves thereof having ears to which said links are pivoted, and the hinge-knuckles projecting in the line of movement of said links, said links bearing on said knuckles as fulcra when in a position to close the doors, substantially as described.

8. In a cab, rock-shaftshaving oppositelyinclined ends, a link connected to the rear ends of each of said rock-shafts, two levers attached to said links, movable struts constituting the pivots for said levers, and means to move said levers simultaneously, said means being under the control of the driver at the rear part of the cab, substantially as described.

In testimony whereof I have signed my name'to this specification in the presence of two subscribing witnesses.
