which operation will he hereinafter de-,

scribed.

fOn the top of the head 1, I place the bearing 28 carrying a, pin 2-9, which pin sup v ports the pawl 30 and extending forward on the pawhl provide the treadle 31.; the two being made integral. and operate on the pin 29 as a pivotal point.

To the pawl 30 I which at its other end is fastened to front head 1 at point 33,

iln the elevating platform I connect the bridge 3dentending across the platform and connecting at each side with link oars 8--8,

1 and on the bricg'e, at its front I place an en- 1 gaging hoolr for the hook 24 and another engaging hoolr 36 or the pawl 30.

At the rear the bridgeil l is provided with a raised abutment 37 which limits the forward movement of the platform upon which the articles to be lifted are placed;=: thcse platforms are usually made of wood and are raised so that the truck can be placed under them when dox n in order to elevate same.

In order to strengthen the elevating frame I connect the bar 38 to link bars 8 8.

To operate the trncl:- when the elevating platform is in its lowest position, the operator forces the hook down into engagement with the hook on bridge 34, as shown in Fig. 2. The handle 22 is then pnlled'into a horizontal position forcing the link bars 8 W iich are connected to the bridge 34, to elevate on the links 10 and allow the pawl filfi'to ngage with the hook 36 on the loridge 34, thus locking the elevated pla form with its load, and to disengage the hook the operator again raises handle 22-and this forces the hook 2 lreorwardly, nntil'it ont of contact with the hook 2,5, zind then, through spring; .27 the hook 2d isthenquickly and automatically pulled 11 into normal position against stop 26, see ig. 5; the spring 27 having been placed at tension when the hook 24 was finfoplaced into engagement with the hook 351*"ln Fig, 4 the piotform is partly raised and not locked showing; hoolc Q l'connected and held in position by the load. on the elevating platform,

After the platform is raised and locked into position'and the hook 24% has automati- Cally been released from hook 35, the tongue or lever 22 is then free to turn in a complete circle laterally, thus allowing the fork 13 which carries the .two front Wheels 17 to turn in all directions. When the elevating platform down. the handle and front the connect the spring 32 Wheels can also be moved laterally and in a circle the same as when the platform is ele- 1 vated; thus it will be seen that the handle and wheels are free to turn in all directions when the platform-is down or up. At no point in the range of this free turning movement of the handle, can the handle be placed in a, position wherein the hook 2% can, through any movement of the handle or of the platform, become engaged with the hook 35, Without first requiring manual foot or hand depression of the hook 24: into the engaging plane: oi the hook In order to lower the elevating platform after it has been elevated, the operator steps on treadle part 31 of pawl 30, thus disconnecting pawl 30 from hook 36, allowing the platform to descend.

While I have described one specific constrnctionof my truck, it will be readily apparent that Lln'ay alter and change the same without departure from the spirit of the in vention, and thus form modifications thereof, and I Wish to be understood as clanning all such modifications w ll still tall Within the scope of my invention.

.Vhet I'claim as new and my invention and desire to secure by Letters Patent is:

1. In an elevating truck, in combination, a base, on elevating platform, a front ing wheel having aswivel connection with said base, a steering handle pivoted to :roclr upon the i'ree upper part of said swivel and having an unlimited. range of steering move ment, and means for connecting said platform to said handle to elevate said platform comprising a member carried by one of said parts and tending normally to remain in or to return to a position in which it will. not interfere with the movement of said handle, the connections between said member and the other part being constituted. by cooperating engaging surfaces on said member and said part so arranged with respect to the direction of elevating movement as to form a positive platform elevating connection,

2. In an elevating truck, in combination, H base, an elevating platform, a front steering wheel mount having pivotal connection with said base, a steering handle pivoted to rock upon the free upper part thereof, and means for connecting said platform to said handle to elevate said platform comprising is pivoted member carried by one of said gorts and tending normally to remain in or o return to a position in which it will not moi-tore with the movement of said handle,

a the connections between said pivoted momher and the other partforming :1 positive platform elevating connection when said pivoted member is manually forced into err gginzenn nt with said other part.

3, in a lifting tr wit. the combination with a nose, on elevating platform and pivoted steering handle,of means for connecting said ')lat'l.'orm to said handle to elevate said platform. comprising a manually operable member connected to one of said parts and tendimg to move out 01' connected relation to the other into a position where it will not interfere with movement of the handle when used for steering.

In a lifting truck. the combination with a base. an elevating platform and a handle lever pivotallv arranged for steerinn movement, of means for elevating said platform comprising a pivoted member on one of said parts and. a relatively fixed member on the'other of said parts, said pivoted member being: normally out of connecting position. in which it will not interfere with the movement of said handle. said pivoted member and said relatively fixed member brought into interlocked coupling relation by movement of the handle and by manual force applied to the pivoted member forcing' said member out of its normal position into the path of'engagen'lent with the relatively fixed member so that the platform can be raised by movement of the handle, and provision for retaining; the platform in elevated position. I

5. In a liftin g truck, the combination with a base, an elevating; platform and ahandle lever pivotally arranged for steering movement. and means for connecting said platform. and handle lever to elevate the platform comprisiim a pivoted member carried by one of said parts, a spring tending to normally hold sa d pivoted member in a position in which itgwill not interfere with the movement of said handle. the connections between said pivoted member and the other part forming a, positive platform elevating connection when said pivoted member is manually forced into said other part. 7

U. A truck comprising: a main frame, a steering." wheel member connected therewith, a handle connected to said steering wheel member for guiding the same, said handle being pivoted to swinogan elevating frame mounted on said main frame and movable up and down relatively thereto, and means carried by said handle and adapted to engage and lift said elevating frame when said handle is moving downwardly, said means carried by the handle tending to automaticall move out of connected relation when the handle is moved in a direction for disengagement. into a position of non-interference with the-handle when used for steering.

'T. In a lifting truck, the combination with a base. of an elevating platform anda pivoted steering handle, of means for connecting said platform to said handle to elevate said platform, comprising a manually operable member connected to one of said parts and tending to move out of connected relation to the other into a position where it will not interfere with'movement of the handle when used for steering, means for locking said platform. in elevated position, and. a treadle, arranged when operated to release said platform from its upper locked position, and. thus permit said platform to lower, said treadle being independent of the handle. and capable of operation when the connecting parts are disconnected and when said handle is in an upper or lowered position and at any time during its turning or steering movement.
