HANSOM-CAB.

SPECIFICATION forming part of Reissued Letters Patent No. 117,734, dated April 18, 1899. Original No. 618,039, dated January 17,1899. Application for reis-sue filed February 28, 1899. Serial No. 707,229.

To @ZZ whom, t petty concern.:

Be it known that I, JOSEPH L. LAWRENCE, a subject of the Queen of Great Britain, residing at Boston, county of Suffolk, and State of Massachusetts, have invented an Improvement in I-Iansom-Cabs, of which the following description, in connection with the accompan ying drawings, is a specication, like letters on the drawings representing like parts.

This invention is an improvement in hansom-cabs, and has for its leading object the provision of simple and positive mechanismv for operating the doors and window which close and give access to the front of the cab, my invention being not only positive and noiseless in its action, but being also not liable to get out of order. In my application, Serial No. (311,365, dated September 27, 1898, I have disclosed a mechanism which although satisfaczo tory from many standpoints yet occupies too much space and at the same time is exposed to view and interference more than is desirable, my said previous invention, moreover, making use of and displaying certain operating-straps, which rapidly deteriorate, are obnoxious to the view, and, moreover, require both hands of the driver in their manipulation. Accordingly I have devised the hereindescribed invention, in which the window is operated positively by a simple movement of of a single hand-lever to the right or left, as required, all the operating connections between said lever and the window being entirely concealed beneath the cab-lining in the framework of the vehicle, and in which the doors are also opened and closed by a single hand-lever, whose connections are likewise entirely concealed, the doors not even having any levers or special devices in View, but being simply provided at theirlower ends with an elongated pintle on rod, which carries a bevel-gear in mesh with a pinion at the adjacent end of a rod connected by a universal joint with other rods and gearing leading to the drivers lever. j

My invention in its details of construction and operation will be more particularly set forth in the following description, and the invention will be further defined in the appended claims.

In the drawings, in which I have shown my invention in its preferred embodiments, Figure lis a vertical longitudinal section through a cab, showing the various details of my invention, mainly in side elevation. Fig. 2 is a vertical transverse section taken on the line 2, Fig. l; and Fig. 3 is a sectional detail of a stop, to be described.

The eab has a body A, with doors a and window l), all of usual or preferred construetion, a usual drivers seat being provided at l the rear, where it is shown broken off at c, the steps and dashboard at the front of the i vehicle being also herein omitted in order to l' present the device in more enlarged detail.

The doors a are properly hinged to the body of the cab by suitable hinges a' a2, the latter having, as herein shown, an elongated pintle I a3, in the form of a strong rod extending down- .ward beneath the floor of the vehicle and a miter-gear a5 Xed thereon. In mesh with this gear is a pinion a6, fast on arod ed?, having a bearing a8 at its vforward end and connected by means of a gimbal or other universal joint a9 at its rear end to a rod al, journaled, preferably, beneath the seat of the vehicle. The rod d10 is provided at its rear end with a miter-gear al?, meshing with a correspondingly-beveled gear als of a horizontal shaft @14, which extends across the vehicle, at the rear side thereof, it being understood that corresponding parts are provided for each door and connect with the shaft am at its opposite ends in order that the doors may be simultaneously*operated. The shaft al* carries an intermediate gear al, meshing with a pinion am of an operating-shaft d, which eX- tends in front of the driver, Where it is provided with a hand-lever als, so that the driver simply by turning this handle one way or the other can positively move the doors a precisely as desired.

Adjacent the hand-lever als. is a second hand-lever b', which, however, is preferably journaled to move in a vertical instead of in a horizontal plane, as the lever als. The lever b' is fast on a stub-'shaft b2, extending just through the wall of the cab, where it is l provided with a beveled gear b3, in mesh with having, below a journal bearing or bracket a4',

ICO

a corresponding gearZ94 of arock-shaft b5, provided at each end with a rocker-arm Z911, connected by a pivoted link Z9T to the free end Z98 of a segmental gear Z99, pivoted at Z910 to the side of the cab and meshing with a spur-pinion Z912, journaled in the side of the cab and having its axle provided at its inner end with a crank-arm Z913, pivotally connected at Z9151 with a bracket Z915, secured at the rear side or end of the window Z9, there being preferably the same mechanism as described for each end of the window.

At its upper edge the window Z9 is provided at each end with a grooved roller Z915, which travels in a slotway or track Z917, herein shown as composed of a rod Z918, bent around parallel to itself (see Fig. l) and covered with leather to constitute a noiseless track.

The window and doors at their meeting ends are rabbeted, as indicated at CZ, in order that they may interlock in usual manner.

It is often desirable to hold the window partly ope-n, slanting outward toward its lower end, and accordingly I provide a stop, (see Fig. l and shown in enlarged detail in Fig. 3,) so that when the lever Z9 is turned suflciently merely to tip the window forward as desired the stop may be engaged with the lever Z9' to hold it. Said stop comprises a plunger Z920, having an enlarged or flanged head Z921 and held normally inward by a spring Z922, as shown in Fig. 3, said spriugbearing against a pin or other hold Z923 at one end and at its 'other end against a shoulder or flange Z924, so that the moment the lever Z9' is moved out from under the engaging lip or flange of the head of the plunger the latter flies against the back of thecab out of the way of 'the'lever. This feature is of particular advantage, in connection with the positive mechanism already described, for adjusting the window,

as, supposingit is raining and yet the weather is suiciently close to require that the window be partly open, this arrangement permits the window to be `thrown out atits lower end enough to admit the required amount of air, while at the same time shedding the rain,

and yet because of the holding mechanism the Window cannot possibly jar or rattle.

In operation when a passenger is to be admitted or wishes to get out, it beingy supposed that the doors and window are closed, the driver, still holding the reins in `his right hand, as usual, grasps the handle Z9 with his left hand and turns the lever slightly to the right, thereby rocking the rock-shaft 295 and cranks 196 forward, so as to swing the segmental gears Z99 to the rear and correspondingly rotate the pinions Z912, Whose arms Z913 positively swing the window outwardly atits lower edge and compel the upper edge thereof to move backwardlybeneath the top of the cab under the guidance of its rollers Z916. It will be observed that the pivot Z914 is near the lower edge of the window, and accordingly when the window is in its open position, with its lower edge then extending forward just under the front edge of the cab, it will be apa7 turning the gears a6 and a5, so as to rotate the rods c3 and open the doors.

It is of great ad van tage to operate the doo/rs by means of positively-connected gearing and shafts, especially when all the parts are concealed, and this is also an important advantage of the window-operating mechanism, inasmuch as there are no parts which can possibly become slack or liable to rattle, and all the power transmitting mechanism is entirely concealed from view and no parts are liable to discommode the occupants of the vehicle.

My invention provides mechanismwhich is permanent in character and not liable to get out of order, being also relatively inexpensive.

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