'7 Claims.
. ram designed for lifting a load either from a platform or the body of a vehicle. I
Another object is to furnish a loader including a substantially vertical mast so mounted that it.
may be turned about its own axis to permit a load to be transferred to or from a platform adjacent the vehicle on which the apparatus is mounted.
A still further object is to supply a loader o the mast and pivoted arm type in which parts are adjustably connected to suit variation in the weights of loads, etc.
With the foregoing objects outlined and other objects in view which will appear as the description proceeds, the invention consists in the novel features hereinafter described in detail, illustrated in the accompanying drawing, and more particularly pointed out in the appended claims.
The drawing is an elevation of the apparatus, shown mounted on a motor vehicle.
Referring to the drawing, l designates a base plate adapted to be rigidly secured by any suitable means, such as bolts 2, to the floor 3, or the like, of the vehicle on which the apparatus is mounted.
A socket or hollow pedestal 4 has its lower end rigidly secured to the base plate and extends upwardly at a slight angle to the vertical, as is clear from the drawing.
A mast 5 has its lower end portion rotatably mounted in the socket, and is provided with a handle 6 to facilitate turning of the mast. an extension I is rigidly connected to the top of the mast and is preferably provided with a-plurality of holes 8 for the reception of a bolt 9 adjustably employed in-pivotally securing the inner end of an arm In to the mast. "H, or the like. having a series of holes [2 is rigidly connected to the medial portions of the arm, and is, in turn, pivotally connected by a bolt l3 to the rod ll of a ram l5. The lower end of the rod has a piston or plunger l6 slid ably arranged in a cylinder II, the lower end of wh ch is pivotally connected at I8 to the mast 5.
with
An apertured plate In operation, the valve can be manipulated to lower the tongs 24, or the like, to grip a load on a platform alongside the vehicle, and then the valve may be turned to introduce the pressure fluid into the lower end of the cylinder.
Such pressure fluid will force the plunger [6 upwardly and, therefore, cause the arm ID to swing in a counter-clockwise direction. When the arm is swung upwardly to the proper height, the valve is manipulated to trapthe pressure fluid in the cylinder, and then the handle 6 maybe turned to cause the mast to transfer the load into the vehicle. Obviously, if the apparatus is employed in unloading the vehicle; this procedure will be reversed.
While the apparatus has been illustrated as mentioned in a truck body near the side of the same, I prefer in some cases to mount it in the -middle of the floor of the truck body with the mast inclined toward an end of such body because in that event, if the load is lifted from a platform arranged at one side of the truck body, such load A pressure fluid, such as oil or water, is introduced into and discharged from the lower end of the cylinder by means of a hose l9, preferably connected to a control valve 20 mounted on the will automatically cause the mast 5 to tumin the socket 4 to shift the load to a position over the truck body without any etfort on the part of the operator.
From the foregoing, it is believed the construction, operation, and advantages of the invention may be readily understood, and I am aware that changes may be made in the details disclosed without departing from the spirit of the invention, as expressed in the following claims.
I claim:
1. An apparatus of the character described, comprising a mast mounted to turn about its lon ax s, means forming the only support for the mast and arranged at the lower end portion thereof, the mast being rotatable for an entire revolution on said supporting means an arm having an inner endpivotally connected to the upper end portion of the mast, load-lifting means con-- nected to the outer end of the arm, and a hydraulic ram connecting a medial portion of the mast to a medial portion of the arm.
2. An apparatus of the character described, comprising a mast mounted to turn about its long axis, means forming the only support for the mast and arranged at the lower end portion thereof, the mast being rotatable for an entire revolution on said supporting means an arm having an inner end pivotally connected to the upper end portion 01' the mast, the inner end of the am being adjustably connected to the mast to permit said end to be raised or lowered, load-lifting means connected to the outer end of the arm, and a hydraulic ram connecting a medial portion of the mast to a medial portion oi! the arm.
3.
