  • 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.
  • 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.
  • 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.
  • Figure l is 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.
  • a pinion a6 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',
  • 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.
  • 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.
  • 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.
  • 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.
  • My invention provides mechanismwhich is permanent in character and not liable to get out of order, being also relatively inexpensive.
  • a door In a hansom-cab, a door, a rod xed to said door in alinement with the hinge-pintle thereof, said rod extendingdownwardly from the lower end of the door and having iixed at its lower en d a gear, a transverse shaft jonrnaled in the bottom of the body at the rear thereof, said shaft having a bevel-gear thereon, a rod extending forward from said lastmentioned gear, and a second rod extending rearward from said first-mentioned gear, said rods being connected by a universal joint and having at their free ends beveled gears mesh-v ing respectively with said two previouslymentioned gears, and ashaft extending vertically at the rear of the cab-body to .the drivers seat and carrying a gear in mesh with a gear on said transverse shaft, substantially as described.
  • a pair of doors a transverse shaft journaled at the rear in the bottom of the cab-body, said shaft having adjacent its opposite ends bevel-gears, said doors each carrying a fixed rod in alinement with the lower hinge-pintle of its door, said rods having at their lower ends gears, and rod connections between each of the door-gearsand said transverse shaft, said rod connections having at their opposite ends gears in mesh respectively with the end gears of the transverse shaft and with said door-gears, and a single shaft extending upwardly at the back of the cab to the drivers seat, said shaft having at its lower end a bevel-gear, and said transverse shaft having an adjacent beveled gear in mesh therewith, substantially as described. 4
  • a pair of doors a rod ICO fixed to each door in alinement with the hingepintle thereof, said rods each extending downwardly from the lowei1 end of its door and provided at its lower end with a gear, an operating-shaft extendingdownwardly from adjacent the drivers seat, said shaft being pro vided at its lower en d with a gear, bevel-gears in mesh with the gears of the rods iixed to the doors, and rod connections connected angularly for operating said bevel-gears from said gearon the operatin g-shait, substantially as described.
  • a Window for closing the front of the cab arms pivotally supporting said window at its opposite ends, a pinion iixed to one of said arms, a segmental gear pivoted to the side of the cab and ⁇ in mesh with said pinion, a rock-shaft and rocker-arm at the rear of the eab and pivotally connected to said segmental gear by a link, and means for rocking said rock-shaft, substantially as described.
  • a Window for closing the front of the cab arms pivotally supporting said window at its opposite ends, a pinion fixed to one vof said arms, a segmental gear pivoted to the side of the'cab and in mesh With said pinion, a rock-shaft and rocker-arm at the rear of the cab and pivotally connected to said segmental gear by a link, a-s'tub-shaft and hand-lever, said shaft being geared to said rock-shaft for 'operating the latter, substantially as described.
  • a Window for closing the front of the cab means between the Window and the drivers seat for operating said Window, said means including a shaft and hand-lever, combined With a stop for locking said lever in an intermediate position for holding the Window partly open, substantially as described.
