ALEXANDER ANDERSON SCOTT, OF KNOXVILLE, TENNESSEE.
ELEVATlNG-TRUCK.
SPECIFICATION forming part of Letters Patent No. 709,245, dated September 16, 1902.
Application filed January 11,1902- Serial No. 891360. (No model To all whom, it 77266;] concern.-
Be it known that I, ALEXANDER ANDERSON SCOTT, of Knoxville, in the county of Knox and State of Tennessee, have invented certain new and useful Improvements in Elevating-Trucks, of which the following is a specification.
My invention relates to trucks in which the platform may be raised or lowered as desired by the operator, and has especial reference to trucks for use in brick-yards for carrying pallets of molded bricks from the machine where molded to drying-racks, and has for its object to provide a truck that is simple in operation, reasonable in cost of manufacture, and capable of carrying very heavy loads.
Further advantages of my invention will more fully appearin the following description and by reference to the drawings, in which Figure 1 is a side view in elevation of the truck; Fig. 2, a top plan View; Fig. 3, a detail view of end of one of the platform-beams, upright, and guide-plate; Fig. 4.. an end view of one of the platform-beams and guide-plate,
and Fig. 5a View of one of the arms and section of platform-beam.
Referring to the drawings,in which similar reference characters indicate corresponding parts throughout the several views, A indicates the base-frame of my truck, which is composed of the side beams A, made, preferab1y,of channel-steel,and the end pieces A, the whole forming an open rectangular frame. B represents axles secured in any suitable manner to the under part of said frame A, and 0 wheels, preferably of the oar-Wheel type, journaled on said axles. D represents uprights, also madeof channel-steel secured to said base-frame A, and E channel-steel beams forming the platform of the truck, having the flat triangular-shaped pieces of metal F secured at the end of each beam E, which are adapted to fit into the channels of the uprights D and serve as guides for the platformbeams E.
G represents arms pivoted in each side beam A,and H rods pivotally connected to each arm G near its center to insure a uniform movement of the two arms in raising naled in the free end of each arm G is a roller or wheel I, that fits into the channel of the platform-beams E and bearing against the top of the channel causes the beams to raise or lower at the will of the operator.
.The operating lever or handle K is pivoted at its lower end to forwardly-projecting ears secured to the front upright beams D and. is pivotally connected to extensions h on the rods H by means of the links L.
M represents a chain connecting each arm G with the platform-beam E, the purpose thereof being to insure a uniform lowering of the beam.
It will be readily understood that by raising the lever or handle K the arms G are pushed backward and the chains M pull the platform-beams E downward, while by lowering the handle K the arms G are raised toward an upright position, and the rollers or wheels I, bearing against the top of the channels in the beams E, cause them to rise.
Having thus described my invention, what I claim is-- 1. In an elevating-truck, a platform mounted for vertical movement, arms pivoted to the base of the truck having their upper ends bearing against and adapted to slide on the bottom of said platform, and means to cause said arms to swing parallel with each other, substantially as shown and described.
2. In an elevating-truck, platform-beams made of channel-steel and mounted for vertical movement, arms pivoted to the base of the truck having one end constructed to travel in. the channels of said platform-beams, and means to cause said arms to swing parallel with each other, substantially as shown and described.
3. In an elevating-truck, a platformmounted for vertical movement, arms pivoted to the base of the truck, wheels journaled in said arms to bear against the bottom of said platform, and means to causesaid arms to swing parallel with each other, substantially as shown and described.
l. In an elevating-truck, a platform mounted for vertical movement, arms pivoted to the base of the truck and adapted to swing parallel with each other, wheels journaled in said and lowering the platform-beams E. J our- 1 arms to bear against the bottom of said platform, rods pivotally connecting said arms in pairs, and a lever connected to said rods, substantially as shown and described.
5. In an elevating-truck, a platform mounted for vertical movement, arms pivoted to the base of the truck' to bear against the bottom of said platform, a chain connecting each arm with the platform, and means to cause said arms-to swing parallel with each other, substantially as shown and described.
6. In anelevating-truck,aplatiorm mounted for vertical movement, arms pivoted to the base of the truck to bear against the bottom of said platform and adapted to swing parallel with each other, a chain connecting each arm with the platform, rods pivotally connecting said arms in pairs, and a lever connected to said rods, substantially as shown and described.
' 7. In an elevating-truck,arectangularbase, uprights rising therefrom, platform-beams mounted for vertical movement in said uprights, arms pivoted to said base, wheels journaled in said arms to bear against the bottom of said platform-beams, and means to cause said arms to swing parallel with each other, substantially as shown and described.
8. In an elevating-truck,a rectangular base, uprights rising therefrom, platform-beams mounted for vertical movement in said uprights, arms pivoted to said base, wheels journaled in said arms to bear against the bottom of said platforn1-beams, rods pivotally connecting said arms in pairs, and a lever conne'cted to said rods, substantially as shown and described.
9. In an elevating-truck, a rectangular base comprising side beams made of channel-steel and end beams, uprights rising from said base made of channel-steel, platform-beams made of channel-steel mounted for vertical movement in said uprights, arms pivoted to the side beams of said base, wheels journaled in said arms to run in the channel of the platform-beam and bear against the top of said channel, and means to cause a simultaneous swinging of said arms through an arc,
substantially as shown and described.
10. In an elevating-truck, a rectangular base comprising side beams made of channelsteel and end beams, uprights rising from said base made of channel-steel, platformbeams made of channel-steel mounted for vertical movement in said uprights, arms pivoted to the side beams of said base, wheels journaled in said arms to run in the channel of the platform-beam and bear against the top of said channel, rods pivotally connecting said arms in pairs, and a lever connected to said rods, substantially as shown and described.
11. An elevating-truck comprising an open rectangular frame mounted on wheels, channeled uprights rising from saidframe, horizontal channeled beams comprising the platform, flat pieces of metal secured at the ends of each platform-beam, said pieces of metal bearing in said channeled uprights, arms pivoted to said rectangular frame, a wheel journaled in each arm to bear in the channel of the platform-beam, a chain connecting each arm with the platform-beam, and means to cause a simultaneous swinging of said arms through an arc, substantially as shown and described.
12. An elevating-truck comprising an open rectangular-frame mounted on wheels, channeled uprights rising from said frame, hori-' zontal channeled beams comprising the platform, flat pieces of metal secured at the ends of each platform-beam, said pieces of metal bearing in said channeled uprights, arms pivoted to said rectangular frame, a wheel journaled'in each arm to bear in the channel of the platform-beam, a chain connecting each arm with the platform-beam, rods pivotally connecting said arms in pairs, a lever pivoted to the front uprights, and a link connecting the lever with each said rod, substantially as shown and described.
In testimony whereof I hereto affix my signature in the presence of two witnesses.
