ELEVATOR TRUCK.
APPLICATION FILED JULY 16, 1911.

CHARLES F. LADWIG, OFMAQON, MISSOURI,
ELEVATOR-TRUCK.
Specification of Lettersfatent. Application filed July 15, 1911. serial No. 638,774.
' Patented June 18, 19112.
To all whom it may concern Be it known'that- I, CHARLES LADWIG,
a citizenv of the United States, residing at Macon, in the county of Macon and State of Missouri, have invented certain new and useful Improvements in Elevator-Trucks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to wheeled trucks for supporting foldable elevators; and it consists in thenovel construction and combination of the parts hereinafter fully described and claimed.
In the drawings, Figure 1 is a side view of an elevator provided with a truck according to this invention and showing the elevator folded. Fig. 2 is a plan view of. the truck and a portion of the elevator. Fig. 3 is a detail view of the crossbar and ring coupling at the pivoted lower end of the elevator. Fig. 4 is a side view of the truck showing portions of the elevator when raised, and with the front axle removed clear of the truck.
The elevator truck is provided with two longitudinal sills 2 which are rigidly secured at one end to the rear axle 3. Rear road wheels 4 are mounted on the spindles 5 of the rear axle, and the uprights6 of the derrick are pivoted to the rear axle. The
- elevator frame or trough 7 has a driving shaft 8 journaled at its lower end, and a shaft 9 is journaled at its upper or free end portion. The elevator has an endless carrier of any approved construction which passes over wheels or barrels on the shafts 8 and 9 and which works in the elevator trough. The otherend portions of the sills 2 are pivotally connected with the lower end portion of the elevator casing by pins 10 which are arranged near the shaft 8.
As shown in Fig. i, when the elevator is raised, and in use, its lower end portion is supported by the ground,
The elevator is provided with a hopper 12 which is pivoted by a shaft 13 to the upper side of the lower end portion of the casing. This hopper contains a suitable conveyer, and it is also arranged to rest on the ground when the elevator is in use. When the elevator is folded up, the hopper is folded over its lower end ortion, as shown in Fig, 1. When the derrick and the elevator are raised they are supported iin their raisedi positions by any suitable tackle or ropes 14. Y
The workingparts 'ofthe elevator audits hop er are notherein more fully described,
as t eir construction is of any approved kind.
A crossbar 15 is provided with arms 16 at its ends and is arrangedbeyond the lower end of the elevator, the arms being securedto the sides of the elevator casing. A clevis or shackle 17 is pivoted to the middle art of the crossbar by a pin 18 and is provided with a coupling ring 19.
The front axle 20 of the elevator truck is one place to another, the .draftpole is raised as shown in Fig. hand the front axle is then pushed back until the hook. engages with the ring 19. i The draft-pole and its arm 23 are then used as a lever to raise the front end portions of the truck sills. When the elevator is folded as shown in Fig. 1, it is sup orted by its truck clear of the ground, and t e truck is drawn along by the draftpole. The hook, ring and clevis form a p1votal coupling 'or connection between the crossbar of the elevator frame and the front axle, which coupling permits the truck to be turned around with the same freedom as if the front axle were connected to the sills by a bolster and king post of approved construction.
What I claim is: i
1. In an elevator truck, the combination, with longitudinal truck sills, and a rear axle and wheels at one end ortion of the sills; of a crossbar arrange at the other end portion of the sills, a jointed coupling device arranged in a vertical plane and pivotally connected with the middle part of the crossbar, a'front axle provided with wheels, a draft-pole secured to the front axle, and
an arm which projects upwardly from the rear part of the draft pole and which has a coupling device at its free end for engaging, pivotally with the coupling device on the crossbar.
2. In an elevator truck; the combination, with longitudinal truck sills, and a rear axle and wheels at one end portion of the sills; of a crossbar arranged at the other end portion of the si1ls, a clevis pivoted to the middle part of the crossbar, a couphng-r n 'enga ing with the clevis, said clevis an 4 coup ing-ring being arranged in a vertical plane, a frontaxle provided with wheels, a
draft-pole secured to the front axle, and an arm which projects upwardly from the rear part of the draft-pole and which has a rear- ',wardly projecting end portion terminating CHAS. F. LADWIG.
