TRUCK.

Application filed May 5,

To all whom t may concern.'

Be it known that I, CHARLES `W. WEST, a citizen of the United States, residing at Tigard, county of Vashington, State. of Oregon, have invented certain new and useful Improvements in Trucks, of which the following is a specification.

NIy invention relates to trucks in general, and particularly to trucks adapted for handling the iron drums that are commercially used for the transportation of oil and the like. The object o-f my invention is to provide such a truck as will lift and hold the filled drum securely raised a short distance from the ground in a position to be easily transported upon the truck.

I accomplish this object by means of the construction illustrated in the accompanying drawing, which is a part of this application for Letters Patent, like characters of reference indicating like parts throughout the several views thereof, and in which:

Fig. 1 is a side elevation of my truck with a drum held therein in position for transportation.

Fig. 2 is an end elevationof the same, with the drum shown in dotted lines upon the ground previous to being raised.

Fig. 3 is a plan view of the truck.

Fig. 4 is a sectional plan view upon line 4 4 of Fig. 1.

Fig. 5 is a detail sectional elevation of the lifting cam upon an enlarged scale, and

' showing the band clamp in lowermost posllIl() tion.

Fig. 6 is a view similar to Fig. 5 but lshowing the band clamp in position for carrying the raised drum.

Fig. 7 is a View similar to Figs. 5 and 6 but showing the band clamp in its uppermost position.

Fig. 8 is a view of the lifting cam from the direction of the arrow 8 of Fig. 7.

Fig. 9 is a fragmentary view of the drum and a section of the clamping band.

In general my truck consists of a truck body having mounted thereupon a vertically movable band clamp adapted to engage and hold the drum, means of elevating the band clamp, and means embodying a novel lifting cam adapted to hold the drum in raised position and to lift the band clamp above the drum as the latter stands upon the ground before or after being lifted.

The truck body consists of a pair of upright'membP/ITS .1Q ,being conveniently ,Steel 1923. serial No. 636,951.

channels as shown in the drawing.A Mounted upon the lower ends of said members 10 are wheels 11. A substantially semicircular yoke 12 is secured upon the lower ends of the members 10 extending rearward therefrom, and forming an abutment to contact with the drum asvthe truck is wheeled up thereto, thus positioning the drum within the truck. A castor wheell?) is mounted upon lll is provided for conveniently transporting the truck manually, said handle being most conveniently pivoted upon the axles of the wheels 11 and high enough to swing over the top of the members 10, so that the truck may be either pushed by the handle extending towards the rear as shown in full lines in Fig. 1 or pulled by the handle extending towards the front as shown in dotted lines in Fig. 1. Hooks 15 are provided to rbrace the handle 14 to the upright members 10.

To grasp the drum 16 for the purpose of raising it I provide a band clamp 17 operated by a right and left hand threaded screw 18 mounted upon the ends of said band 17 by trunnioned nuts 19 and operated Amanually by ahand wheel 20, as shownv in Fig. 3. The band 17 is convenient-ly lined with blocks 21 o-f wood or similar material, and to allow the blocks 21 to. disengage themselves readily from the flange o-f the drum the upper ends of the blocks-are beveled, as shown in detail in Fig. 9.

To raise the band 17 I provide a pair of novel cams 22 mounted above the band 17 upon the members 10 by suitable boxes, and connected by a shaft 23. A hand lever 24is mounted upon one of said cams 22 to operate them. A convenient method of mounting said lever is by supplying a squared end 25 upon one of said Cams to receive the hub of the lever, and securing the lever thereupon by a nut threaded upon an extension 26 of the cam, as shown in Fig. 8.

The function of Jche cams 22 is three fold,

Yfirst to lower the band 17 so it may engage the drum, second to raise the drum and hold it securely in raised position, third to raise the band 17 above the drum when the truck is idle. These three functions are illustrated in detail in Figs. 5, 6 and 7.

e5 said yoke centrally of the truck. A handle f The cams are constructed-with a substan- I y raised position.

` n The operation of my truck is as follows:

The truck is Wheeled up to the druin until the drumcontactsnvvith the yoke l2 and is thus properly positioned Within the truck fbody to receive the band 17..A vThe lever 24 is then turned until the cams 22 are' in thepposition sho'ivn' in Fig. 5 and the band 17 in its lowerinost position and .embracing the upper end of the drinn. The band 17 is then clamped upon thel driin by means of th'e handwvlieel 2O.V The lever 24 is then turnedv until the cams 22 assu'ine the' position shown in Fig'. 6.`k The drui'n is thu's automatically suspended upoii the truck, because the Cables 32 have passed beyond the center of the sliaft 23 and the Weight of the drum is tending to rotate the eanis 22 counter-clo'ckwis`e5 or iiithe direction of the ai"- r'oW of llig. 6,- Wh-ich rotation is rendered impossible by reason of the i'ini27 of the cams contacting ititli the Cables 32, as shown in Fig. v6. Thus a simple Inve'nient of the lever 24 raises the druiii and locli'sV it in trans'portedV upon the ti'iclrto any desired destination. To loivei vthe drum tok rthe ground againthe liever 24 is rotated clockv'v'ise thus returning the Cams to the position of Fig. and loiveringthe drum, Whereupen the band '171s' released frein the drum The dr'uni may theirV be by means of the hand Wheel 20". The band 17 is then raised clear of the top of the drum 'by rotating,` the lever 24 counter-clock-Wise until the earns-assume the position shown in /Fig 7, whereupon the band 17 Will have beenV raised to its uppermost position above the top of the drum, as shown in Fig. 2.

My device may be made of any size, and constructed of any materials deemed convenient and suitble for a device of this character, and tvhile I have'illu'strated and described a form oi' Vconstruction and arrangement o'f parts found desirable in inater'ializing my invention, I Wish t0 Vinclude in this application all mechanical equivalents and substitutes that' may 'fairly be elonsidered to come Within `the s'vco'pe and purviexv' of lIii'y invention as'detiii-e'd in the ap- 13`er`ide`dV claim. Y

Having' disclosed my invention so'. that others may be enabled to eo'iistruet andto use the saine, what I claim as new, and de- Sile to' Secure VLetters' 'Patent is:

In a truck for handling drums-2 draingrasping mechanism; earns to Operate said mechanism, ea'ch of said cams consisting of a pairv of hubs,`V rim, and sides spaced apart one from the other and connecting said riin with s'aidwhub's, and an Helm pin mounted in said sides :ma ningls'aid space; and flexible nienberssecured to said pin'afi'id tdsaid grasping rn'echanism; and ineaiis to operate said Gains.

In Witness whereof I claim the-'foregoing my Own I hereunto aan; signature at 'iwi-timid, cenni-y 4of Multnomah, State @if Uregou'i', this Otl''dy 'of/April, 19273'.
