of outh Dakota, have invented certain new and'useful Im rovements in Barrel-Trucks,

of which the ollowing is a s cification.

The present invention invo ves improve- ,ments in that type of trucks designed articularly for lifting and moving barrels om one place to another and embodying a suitable wheeled supporting frame heavy article, and suitable means for raising andlowering the runner.

or a full understanding. of the present' invention, reference is to be had to the'following description and -tothe accompanying drawings, in which- Figure 1 is a. vertical sectional view, certain parts being shown in elevation, illustrating a truck embodying the essential features of the invention; Fig. 2 is .a horizontal section taken on the line 22 of Fig. 1, looking downwardly; Fig. 3 is a rear elevation; Fig. 4 is a detail plan view of the lifting lever and dog mounted thereon; Fig. 5 is a detail section on the line 5-5 of Fig.- 1;

Fig. 6 is a detail sectional view showing the withdrawn position of the locking catch carried .by the runner.

Throughout the following detail description and on-the severalfigures of the drawlugs, similar parts are referred to by like re crence characters. In the drawings, 1 denotesthe frame of I the truck which is supported u n suitable wheels 2 the side sills of the ame terminating at one endin handles 3. A vertical frame 4 extends upwardly from the wheeled frame 1 between the ends of the latter and are also provided, at one side of "the member between the sides of the frame 4 is the vertical standard 5, the latter being of T-shape in crosssection and its centralrib or web 5 being toothed vertically or longitudinally thereof, as shown at 6. On the standard 5 5, a pluralit 10f notches 5".

A runner having a vertical groove of somewhat T-shape to conform with the cross sectional shape'of. the standard 5 is mounted.

upon said standardfor vertical movement and is provided at opposite sides thereof with pairs of pivot lugs 8 between which a runner having lifting arms to engage the barrel or other nAnnnL-rnuc'x. I

are pivoted the lifting arms Each of the arms 9 carries a gripping block 10 at one end while at its other end it is provided with a plurality of teeth 11,. A flat spring 12 is socured to the front side of the runner 7 andv "the opposite ends of said spring bear against the inner curved sides of the arms 9, normally tending to force said arms apart. As apparent from the drawings, the arms 9 are pivoted between their ends to the lugs .8 and the rear toothed end portions of the arms are adapted'to beengaged by the pawls 13 which are pivoted to the runner 7 and which, when engaging the teethll, will hold the arms 9 in operative en agement with the object which is to be lifted and moved by means of the truck. 1 I

I The runner 7 is'adapted to be raised by a lifting lever 14 which is provided at its inner end witha yoke 15 pivotally connected at its opposite sides to the opposite sides of the runner 7 as shown at 15 The yoke 15 comprises complemental plates secured to the opposite sides of the inner end of the lever 14 and pivotally mounted between projecting portions of the plates forming the yoke is the lifting dog 16 arran edto en- 1 gagethe teeth 6 of the standard in order to cooperate with the lever. 14 to lift the runner 7 by a ste by step movementas said lever 14 is raise and lowered by the oper-' ator. A pull rod 17 connected at one end to the dog 16 is attached at its opposite end the lever 14 and dog 16 by means of a sli ing catch normallyforced into engagment with the notches 5" by means 0 e s ring 22 said catch being mounted between t e sides of a yoke 23 secured to the runner. A hand rod is connected to the catch 21 and formed with a flat handle 24 which normally operates throu ha verticalslot in the outer end of the yo e 23. When the handle 24 is operated to withdraw the catch 21, as shown in Fig. 6, said handle may be turned so that its flat body is arran transversely with respect to the slot in e outer end of the yoke 23, whereby the catch 21 will be held in its withdrawn position, as shown in Fig. 6, this being a desired ad ustment preliminary to lowering the runner '7. -The gripping surfaces of the blocks are pref-l erably serrated or roughened to increase their grip ing action.

It will used by moving the truck toward the barrel or other object, the arms 9 being thus engaged with the object and locked in such engagement by the pawls 13. By successiv'ely lowering and raising the ler erl l, the barrel will be raised by the arms 9, until it reaches a suitable elevation, whereupon the runner 7 will be held at its adjustment by .the catch 21 which must be released ,pre-

vious to lowering the runner for depositing the object supported by the arms -9 at itsroper place. In order' to facilitate simu taneous adjustment or movement of the arms 9, the rear ends of said arms are 1 connected by the links 9', with one of which operable means for simultaneously disen-' is formed a suitable handle 9" adapted to be readily pulled so as to correspondingly move the arms 9 toward andfrom one another.

Itis contemplatedalso to provide readily gaging the pawls 13 from the teeth 11 of. the arms 9 for which lpurpose said pawlsare connected b a togg e joint 13, the pivot connecting t e adjacent ends ofthe members of said joint being slidable' in a slot 25 on a bracket 26 rejecting from the member 7. A vertical pu 1 rod 27 is connected by a link 28 with one of the members of the toggle joint 13 and the pivotal member 27', ,connectin .the link 28 to the pull rod 27 is 'slidab e vertically in the slot 2 8' which latter is provided in, a vertical extension of the bracket 26. The .rod, 27 is formed'with a .notch 29 near its upper end in'which is adapted to be engaged a locking rod 30 movable by a hand lever 31. It will be apparent that when the lever 31 is depressed the-rod 30 will be en ged with the rod 27 so that by lowering t e lever 14 the joint 13 will be forced outwardly on the bracket 26 and the pawls 13 simultaneously disened from the teeth 11. aving thus described the invention, what is claimed as newisr 1. In a barrel truck, the combination of a wheeled frame, a vertical standard carried thereby and having a vertical toothed per tion, a runner movably mounted upon said standard, .a lever ivoted to said runner, a lifting do carried bysaidlever toen'gage the tooth ortion of the standard to raise the runner gya stepeby. step 1 movement, lifting arms pivoted tween their ends to opposite sides of the runner, a spring secured to one side of the runner and havin its ends engaging the front end portions 0 the lifting arms, normally tending force e apparent that the invention is lifting dog .carrie the tooth the latter apart, gripping means carried by the front ends of the lifting arms, and pawls coacting with the rear ends of the lifting arms to lock the latter in engage ment with an object.
