TRUCK.

Application filed November 15, 1920. Serial No. 424,271.

To all whom it may concern:

Be it known that I, HERBERT B. SABIN, a citizen of the United States, and a resident of Cleveland Heights, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Trucks, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle,'so as to distinguish it from other inventions.

The present invention relates to barrel trucks and more particularly to trucks of the general type disclosed in my copending application filed October 15, 1919. Serial No. 330,770, now issued into United States Letters Patent No. 1,358,881 dated November 16, 1920. More particularly the invention relates to modifications of the truck shown in my previous application, but to trucks which are adapted to lift barrels or containers; where the truck clamps or grips the container but does not lift by means of a foot or the like.

The present type of truck is adapted to be moved adjacent a barrel or container and to engage the same whereby final movement of the truck adjacent the container first tiltsthe container upon one edge slightly. The container is not lifted from the bottom but is lifted by a ring or other reinforcing member attached to the side wall of the container. Thus the container does not have to be moved or tilted at all by hand and the user of the truck is enabled to expeditiously handle heavy loads. To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawing:-

Fig. 1 is a perspective view of one form of truck; Fig. 2 is a side elevation of this form shown in position to engage and lift a container; Fig. 3 is a section onthe line 33 of Fig. 2; Fig. 4 is a section on the line 4-4 of Fig. 2; Fig. 5 is a side elevation of a modified form of truck in position to engage with a container; Fig. 6 is a broken front elevation of the truck shown in Fig.

5; Fig. 7 is a sectional view on the line 77 of Fig. 6; Fig. 8 is a side elevation of another modified form truck standing against a container; Fig. 9 is a broken front elevation of the form shown in Fig. 8; and Fig.

10 is a section on the line 1010 of Fig. 9.

The present trucks are particularly adaptable to use with metal barrels or containers which are standard articles of manufacture but which are made in standard heights and the metal containers vary in detail as to height, diameter and position and type of chime and reinforcing rings or hoops. Certain standard types of metal containers are commonly made with an overturned flange at the top as shown in Fig. 2 and the present forms of trucks are particularly adapted for use with this general type of barrel with a spaced flange whether the flange is at the top of the barrel or formed as a separate ring or hoop around the body of the barrel or container.

The form shown in Figs. 1 to 3 is adapted to be used with a metal barrel or container 1 having a downwardly extending flange 2 at the top where the flange is spaced from or overhangs the barrel body proper. It is of course, obvious that a reinforcing ring or hoop 3 having a spaced or overhanging portion 4: similar to the flange 2 may be employed as long as it is mounted above the center line of the container. The truck consists of a base member 5 provided with tracanced when the handles are in the natural easy position for the operator to handle.

The frame members are provided with a series of spaced apertures 12 arranged at such heights as will meet the usual heights of containers. A lifting cross bar 13 is adjustably secured to the frame members by bolts 14; or other similar devices which pass through the cross bar and the apertures12. This cross bar is provided with a container lifting member 15 formed integrally with or securely fixed to the cross bar at approxiattached to the base member .of the truck.

As soon as the truck is pushed against the container so that the body of the container contacts the seat 7, the truck is tilted or tipped rearwardly about the axis passing through the wheel centers whereby the container is lifted completely from the floor. As before stated, when the user tips the truck to raise the barrel, the balancing point is reached at approximately the position where the user would naturally hold the handles to move and push the truck about.

In the form shown in Figs. 5 to 7, the barrel 21 is of the type which has an upper reinforcing or chime ring 22 which is usually but not necessarily at the upper edge of the container body. In this case the container is shown as being provided with a reinforcing ring 23 having a portion 24 spaced away from or overhanging the container body but this ring is placed below the center line of the container instead of above as is the ring 3 on the first form of container. The ring may be divided or there may be a series of overhanging elements in place of the complete ring.

Here the truck is made up of the usual base 25 having the wheels 26 but the cross member 27 of the base which carries the curved seat 28 is spaced back from the center line of the wheels as will be evident from Fig. 7. Pivotally attached to the base is a cross bar 29 which is preferably U-shaped and provided with a lifting member 30.

This cross bar is preferably mounted on trunnions 31 but any suitable pivotal mounting could be employed. The side base members are provided with arcuate slots 33 in which move pins 34 attached to the'cross bar and this limits the movement of the cross bar so that it is normally in the position shown in Fig. 5 ready for engagement with the spaced portion 24 of the reinforcing rin 23. As shown, the cross member is so mounted that when the container is lifted, the member is thrown back past center thus maintaining itself in its container engaging position. p

The frame members 35- are suitably attached to the base and extend upwardly having the usual handles 36 and cross rod 37. At the usual container height, a cross member 38 is mounted by means of bolts 39 passing through aligned apertures 40 in the frame members and these apertures 40 are so arranged that the crossmember may be adjusted for difierent heights of containers. On this cross member is mounted. an upstanding pin 41 on which is movably mounted a clamping book 42 which engages over the top of the container to hold it adjacent the cross member, the hook having a handle 43 by which it may be moved. The base of this truck is also provided with a foot pedal 45 b which the truck may be pushed in towar the container.

In lifting a container with this form of truck, the truck is moved adjacent the container until the hook 42 can be moved over the upper edge of the same. Then by holding the handles and pushing inwardly, the truck is forced closely adjacent the container at the bottom which engages the lifting member 30 .under the spaced reinforcing ring or overhanging element and tilts the container slightly about the portion 16 of I its base. As soon as the truck frame assumes its vertical position adjacent the container, the truck is tilted rearwardly as a whole lifting the entire container which is supported by the lifting member 30 and held against the truck at the'top by the hook 42. Both this form as well as the first form .of truck areprovided with legs 47 which allow the truck to stand upright and which also surround the container to maintain it in position on the truck.

In the remaining figures a slightly different form of truck is shown which is adapted to be used with a barrel 50 which has an upper chime ring 51 or a reinforcing ring 52 where the ring is either weak or where through the general container construction, it is unwise to carry heavy load from the chime or ring. In this form, the same one man feature is employed, and the same method of originally tilting of the container about the portion 16 of the baseor bottom. In this form .the truck has the usual base 60 and traction wheels 61 with the frame members 62 and upper handles 63 and cross rod 64, the base having the curved barrel seat 65 and foot pedal 66. In this form however, the base member is provided with two forwardly extending feet 67 connected by a reinforcing rod or bar 68, the feet being pivotally mounted on trunnions 69 of the base and being connected to the frame members by links 70 having slots 71 which engage with the pins 72 on the feet, allowing slight movement of the feet.

At or near the height of the barrel the truck is provided with the cross bar 7 3 having the upstanding pin 74 and hook member 75 similar to those in the second form but the cross bar is here provided with a lifting member 76 which is adapted to be engaged under the ring or chime of the container.

The cross bar is adjustably mounted on the frame members by the usual bolts 77 passing through the apertures 78 so that containers of different heights may be lifted.

In this form the truck is moved adjacent the container until the lifting dog is moved under and against the reinforcing ring, and then the hook is engaged over the barrel edge to maintain the container in position. This brings the carrying feet adjacent the bottom edge of the container. As the truck is pushed toward the container, the container is lifted or tilted about the edge 16 thus allowing the feet to slide under the container bottom. The lifting dog does not have a secure engagement however and as the truck is tilted backwardly, this dog disengages due to the loose connection by the hook member allowing the weight of the container to rest upon the feet, the container being held against the truck at the top by the hook member as in the second form.

It will thus be seenthat in all forms the same feature of primarily. tilting the container about the edge 16 is retained and in each case the container is held close to the frame members at the top, but the actual carrying means are slightly different depending upon the type of container. The truck may still be used and operated by an individual as the container does not have to be lifted or tilted by hand so that the truck may be engaged. In general aspects the present types are similar to the truck disclosed in my application before mentioned but the new forms allow all types of metal containers to be handled. In actual practice the present types of trucks allow one man to 11ft and move containers which weigh upward from seven hundred pounds and the operator needs no outside assistance either in picking up the container or in Iplacing the same in position. It is also 0 vious that certain types of wooden barrels maybe lifted with these same trucks and particularly with a truck such as is shown in Figs.'8 to 10 where the hoops or reinforcing rings would not have to bear the entire load. Ease of operation and the ability to handle heavy loads is of importanceas well as the simplicity of the truck itself which may be made strong and durable and yet be comparatively light in weight.

Other modes of applying the principle of my invention may be employed instead of the one explained, change bein made as regards the mechanism herein dlsclosed, provided the means stated b any of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention 1.
