ELEVATING-TRUCK.
Specification of Letters Patent.
Patented Dec. 3, 1918.
Application filed February 21, 1918. Serial No. 218,555.
To all whom it may concern:
Be it known that I, JACQUES WILLER, a citizen of Russia, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Elevating-Truck, of which the following is a full, clear, and exact description.
This invention relates to elevating devices and particularly to an elevating truck, and has for an object the provision of an improved construction which may be quickly and easily shifted from one position to the,
other either with or without the load.
Another object of the invention is to provide a truck in which inclined planes are used'with means for locking the elevating section in alowered or raised position.
A still further object of the invention is the provision of an improved arrangementof elevating trucks wherein the lifting planes may be arranged either on the movable section or stationary section, and locked in both the elevated or depressed position.
In the accompanying drawing:
Figure 1 is a side view of a truck disclosing an embodiment of the invention.
Fig. 2 is a top plan view of the truck shown in Fig. 1, certain parts being broken away for better illustrating the structure. I
Fig. 3 is a sectional view through Fig. 2 on line 3-3, certain parts being broken away.
Fig. 4 is a view similar to Fig. 3, but showing the parts in a depressed position.
Fi 5 is a view similar to Fig. 3, but showing a slightly modified structure.
Fig. 6 is a transverse sectional, through Fig. 3 on line 6-6. I
Referring to the accompanying drawing by numerals, 1 indicates a base or frame formed from any desired material, preferably U iron as indicated in Fig. 6, and arranged upon frame 1, and positioned so as to telescope thereover to a certain extent, is a movable frame or section 2 which acts as an elevating section. Base 1 is provided with supporting members 3 at the rear of any desired kind, as for instance Wheels,
' and supporting members 4 at the front of any desired kind, as for instance ordinary swivel iron casters. These supports may be large or small as desired, but so positioned that the top of the wheels will not project above the frame 1 whereby. said frame, when theparts are in the position shown in Fig. 4;, may be moved under a body and then the elevating section 2 raised a short distance, and may therefore be transported by the truck to any desired place.
The base 1 is provided at the front with atongue 5 which may be swung to substantially any position and to which is secured a chain .6, said chain in turn being secured at 7 to the lifting section 2 so as to move said lifting section forward from the position shown in Fig. 4 to that shown in Fig. 3. The frame or base 1 is provided with a plurality of blocks 8, there being. a block 8 for each side of the base at each end and each of said blocks. being provided with a 10 and 11 will roll up the cams or inclinedportions 9 and will raise the section 2 a pre-' determined distance, and consequently will raise anything placed on section 2. The tongue 5 must be used for positively pulling the section 2 forwardly, but when it is desired to move the section rearwardly and downwardly to a lowered position, a spring 12acting on the axle 13 connected with the traction members 3 and on the transverse bar 14 of frame 2 will automatically pull the frame of section 2 rearwardly and down wardly. In order to prevent an accidental rearward movement at the wrong time a substantially L-shaped catch 15 is rigidly secured to the transverse bar 14 and normally presses against the transverse bar 16,
which acts as a removable stop. Bar 16 is rigidly connected with the side arms or levers 17 which are pivotally mounted at 18 and 19, and which are normally held in their elevated position as well as transverse bar 16 by one or more springs 20 as shown in Fig. 6, and in this way the transverse bar or stop '16 normally remains in engagement with the catch 15. lVhen it is desired to lower the elevating section 2 pressure is placed on the treadle or step 21 and the stop or transverse bar 16 depressed against the action of springs 20 until the catch is released whereupon spring 12 or the weight on ront beveled members or section 2 will move the catch 15 rearwardly and downwardly until the catch slides into the slot 22 and the catch finally engages the shoulder 23 of the plate 24:. When the device is to be elevated a forward swing of the tongue 5 will cause chain 6 to pull the elevating section 2 forwardly and as said section moves forwardly the catch 15 will strike the guiding cam 25 and ride over the bar 16 until it engages infront of said bar, whereupon the section will be elevated and locked in an elevated position. In forming the device blocks 8 may be made of Wood or other material and also the cam members or inclined portions 9 may be at any desired angle without departing from the spirit of the invention.
In Fig. 5 will be seen a slightly modified form of. the invention in which the wheels 10 and 11 are secured to or mounted 'on the base 1 while the elevating section is provided with elevating cams 26 and 27 -c'oacting with the rollers 10*and 11. The parts of the section 2 which carry the lifting earns 26 and 27v-may be part of the section or may be blocks of wood or other material mounted in said section and secured thereto by bolts or any other desired manner.
What I claim is: I
1. An elevating truck comprising a base, an elevating section, means arranged between the base and the elevating section for causing anelevation cit-said elevating section when the elevatingsection is moved in a predetermined direction independently of the base, manuallyoperated means for moving said elevating section so as to cause-the same to "elevate, a catch-connected with said elevatingsection, and means for lockingsaid catch when the elevating section has been elevated, a pair of arms pivotally'm'ounted on said base, a cross bar connected with said arms arranged in back of the catch, and resilient means'for normally holding said cross bar and said armsin engagement with said catch.
ers engaging said ways, means connected with the front part of the elevating section for moving the same longitudinally of the baseand thereby causing the elevation thereof as the rollers move up said ways, a catch arranged atthe front o1? the elevating sec- 7 tion, a cross 'barinterlocking with the catch for holding the catch and the elevating sec tion in its elevated position, a pair of arms connected with said cross bar, said arms being pivotally connected tosaid base, at a distancefrom said cross bar, whereby the cross bar is given a substantially vertical up and down movement, a spring normally urging said cross bar upwardly, and a stop on each of said arms for limiting the rearward movement of said catch and the elevating section secured thereto.
3. An elevatino truck comprising a base, a ,pair of inclined ways at the front of said base and a second pair of inclined ways at the rear of said base, an elevating section mounted on said base provided with a bearingr'oller for each of said inclinedways, means at the front of said elevatingsection for moving the elevating section longitudinally of the base and thereby causing said rollers to engage said ways and elevate said elevating section, a catch connected with the front of said elevating section, means interlocking said catch for holding the catch and the elevating section in their elevated position,
a dplate having an aperture therein arranged. i
acent said catch, said plate at the lower end presenting a stop tor engaging said catch when the same enters said slot for limiting the rearward movement of the catch and ele'vatin section whereby the elevating section is loc ed both in an elevated position and a lowered position.
