Application filed April 28, 1910. Serial No. 558,251.

To all whom it may concern:

Be it known that I, THOMAS S. CHasNU'rr,

a citizen of the United States, residing at Oklahoma city, in the county of Oklahoma 5 and State of Oklahoma, have invented cer tain new and useful Improvements in Loading-Trucks, of which the following-is a full, clear, and exact description, reference being had to the drawings hereto annexed.

This invention pertains to the class of loading-trucks in which the platform or bed portion is movablevertically, and in which means are provided for raising of lowering said platform and its load.

Letters Patent Number 911,111 were issued to me on February 2, 1909, for improvements in loading-trucks, and one of the objects of the present invention is to improve upon the means shown in said Letters Eatent for raising and supportingthe platorm.

Another object is to improve upon the construction of the main body or framework of the truck. I

Other objects and advantages of the invention will be set forth in the ensuing description.

Referring to the accompanying drawings: Figure 1 is a left-hand side elevation of the improved loadin -truck, showing the plat-i form elevated. ig. 2 is an inverted lan 'view of the loading-truck on same sea e as Fig. 1; the platform, supporting wheels,

and axles being omitted. larged .fragmental sectional view, taken on the line 3-3 of Fig. 2. Fig. 4 is a pe 'ctive view ofthe front end of the frame-work of the loading-truck. Fig. -5 is a similar view of a portion of angle-steel, cut for into a portion of the frame-work.

" Fig. 6 1s a view of the same piece of anglesteel, after it has been sha ed and welded.

Referring to the severa figures, in all of which like characters of reference designate like .parts, the improved loading-truck, hereinafter referred, to as the truck, comprises a main frame-work 7, which is supported by four ground wheels 8. This fr consists, in

part, of the right and left side eras-pieces are riveted to saidside pieces; and rearcross-pieces 10 are 10, which The front formed ofangle-steel, as are also the side pieces 9, the, vertical portions 10" of said or folded around at rig t angles and riveted flatly against'the Fi .3is anen be interposed between said ame-work 7 standards, them washers in outside surface of the front and rear ends of the corresponding portions 9* of the side pieces 9. However, fore being assembled-with the cross+pieces 10 as just described, have their ends bent squarely upward, as, best shown in Fig. 6, this being done by first cutting away a part of the vertical portion 9 of said side ieces, as at 9 in Fig. 5, and then bending said ends the side pieces 9, be

upward and welding said vertical portions 1 in Fig. 6. In addition to the front and rear pieces 10 aforesaid, the frame-work 7 is providedat each end with a second or u per together on the miter joint line 9 as shown cross-piece 11 of angle-steel, the upper ori- Y zontal portions 11 of these cross-pieces having their-ends 11 lapped downward and riveted .to the outer face of the upturned end portions 9 of the side pieces 9. The framework 7 is furthe'rprovided with cross-pieces 12 of a Ie-steel near its front and rear ends, the vertical portions 12" of said cross-pieces being bent at right angles and riveted flatly against the inner faces of the vertical portions 9" of the side ieces 9.

' The frame-work of its four corners with abase-plate 13 which is riveted to the horizontal portions 9 and 10 of the side pieces 9 and end crosspieces 10, respectively, these base-plates be- '1ng designed'to support certain standards later described. A standard 14,. in the form of a round shaft, is inserted rigidly into a hole 13", in each one of the four base-plates 13, the upper cross-pieces 11 at each end of the frame-work 7 hemg provided with holes 11 directly above the holes 13 of the baseplates 13 to receive said standards and cer-' tain sleeve members carried thereby. A

beveled gear-wheel 15 is mounted revolubly ion the lower portion of each standard 14,

and rests upon its respective base-plate 13, each base-plate being provided with a circular'ball-race 13 so that ball bearings may r-wheels and base-plates if desired. In addition to the gear-wheel-15, each standard 14, is embraced by a tubular sleeve 16, mounted revolubly upon it, this sleeve being provided on its lower end with gear-teeth 16" which detachably engage correspon gear-teeth 15" on the hub portion 15 of sai gear-wheel. The sleeves 16 are held downward on their standads 14 by cap washers 17 at the tops of and turn me 5 down by pinsiS passing through the tops of g is provided in each one I said standards. The outside of these sleeves 16 are screwthreaded and have screwthreaded en agement with lugs 19 on the ends of the p atform 20,.so that by revolving said sleeves said platform is raised or lowered to any desired height.

To afford strength and r1 'dity to the standards 14, the sleeve 16 0 each is embraced by a bearing-plate 21, these bearing,

plates being riveted to the upper facesof the upper cross-pieces 11.

For revolving thesleevesi 16, a shaft 22 is journaled horlzontally across under the these bars. This shaft 22 carries two beveled gear-wheels 26 which engage the gear- I wheels 15 on the two front standards 14, so

the platform 20.

that by revolving said shaft the screwthreaded sleeves 16 are revolved to raise or'lower A shaft 27 extends along under one side of the frame-work 7, the front end of this .rear base-plate 13. This shaft 27 is shaft being journaled in a bearing 28 bolted to the under side of the left-hand front baseplate-13, and its rear endin a bearing 29 bolted to the under side of the left-hand rovided at its front end with a gear-whee 30 engaging the gear-wheel 15 of the left-hand front standard 15 of the left-hand standard 14, and its rear end with a gear-Wheel 31 engaging the gear-wheel 15 of the left-hand rear standard 14. In addition to its bearings 28 and 29, the shaft 27 is provided with bearings 32, which are secured to the under sides of the inner cross-pieces 12.

A third shaft 33 journaled laterally under the rear end of the framework 7 in bearings 34 bolted to the under sides of the rear baseplates 13, and this shaft is likewise provided with beveled gear-wheels 35 engagin the gear-wheels 15 of the two rear standar s 14.

By the arrangement of the parts described, it will be seen that by revolvin the front shaft 22 the gear-wheels 15 of the ont standards 14 will be caused to run, thus driving the front screwthreaded sleeves 16.

Since the gear-wheel 15' of the left-hand front standard 14 is operatively connected with the gear-wheel 15 of the left-hand rear standard 14 through the shaft 27- and its gear-wheels 30 and 31, and since said gearwheel 15 of said left-hand rear standard is operatively connected with the gear-wheel 15 of the right-hand rear standard through the rear shaft 33 and itsgear-wheels 35 a revolving movement imparted to any one of said shafts 22,27, and 33 will cause all of the sleeves 16 of the standards 14 to run,

thus allowing the platform 20 to be raised or lowered at will.

For driving the front shaft 22, its outer I or left-hand end is' provided with a toothed wheel 36, and with a loose lever37, the pivotal end of saidlever being bifurcated to straddle said wheel on said shaft. This lever 37 is provided in its pivotal or bifurcated end with a crescent shaped pawl 38,

whose central portion is pivoted in said lever in a manner to allow either of its ends to be swung into operative engagement with the Wheel 36 as a ratchet pawl. For throwing the lower end of this pawl 38 into position to engage the toothed wheel 36, the shaft 22 may be slowly and forcibly revolved by swinging the rear or freesend of the lever 37 upward and downward, thus raising the platform 20 under heavy load to a position where said load may be transferred to another and higher vehicle or support. By shifting the opposite end of thepawl 38 into engagement with the toothed wheel 36 a vertical swinging movement of the lever 37 will cause the platform 20 and its load to be lowered. i

The foregoing being a full, clear, and exact description of the" invention, what I claim and desire to secure by Letters Patent is: l

1. In a truck, the combination of a supporting frame, a series of standards projecting upwardly from the frame and rigid therewith, gear wheels journaled upon the lower portions of the standards, means for simultaneously turning the gear wheels, threaded sleeves slipped removably upon the standards and having an interlocking connection with the gear wheels so as to revolve upon the standards with the gear wheels, a platform, and means carried by the platfornr for engaging the threaded s eeves.
