SLEEVE EXTENS ION ADAPTER Filed April 1, 1966 INVENTOR. 60 17. P553451 Qaigmdew United States Patent US. Cl. 214-653 1 Claim ABSTRACT OF THE DISCLOSURE A sleeve extension adapter for use with a Bartell equipped lift truck having a horizontal extensible boom and a depending pin or article engaging member at its outer terminal end, in which the sleeve extension adapter is a tapered bar formed of at least three cylindrical integral sections of different diameter with the larger diameter section at the top. Formed in the larger diameter section is an axial closed bore of a diameter and length such as to snugly receive the depending pin therein, there being aligned openings in the pin and the walls of the larger diameter bar section to receive a fastener bolt therethrough. The adapter when mounted on the pin will permit the Bartell lift truck to lift roll loads of a width less than the conventional standard width of roll loads normally handled by the lift truck.

This invention relates to a sleeve extension adapter for use with a Bartell equipped lift truck for the transport of a roll of printing paper.

Rolls of printing paper in shipment in freight cars stand on end with their axes vertical, the lower end of the rolls engaging the floor of the freight car. A roll of printing paper is of large diameter and normally of a standard height. There is in use what is known as a Bartell equipped power operated lift truck that has a boom on a support carriage, and a depending pin on the boom that is inserted into the axial sleeve or core of the roll of printing paper at its upper end. Power means pulls the pin to the support carriage and moves the roll into a clamped engagement with a cradle carried by the support carriage. The roll of printing paper thus clamped in position can then be elevated by a raising of the support carriage and transported by the lift truck to its selected location. Where, however, the roll of printing paper is of a width smaller than the conventional width of a roll of printing paper, the pin which is relatively short cannot be inserted far enough into the axial sleeve or core of the roll, and in some cases cannot be brought down low enough for insertion into the axial sleeve or core of the roll, so as to move the same into clamped seating engagement in the cradle of the carriage support.

Accordingly it is the principal object of this invention to provide an adapter for connection to the pin on a Bartell equipped truck that will function to provide a pin of increased length sufiicient for use with rolls of printing paper of smaller width.

Another object of this invention is to provide a rigid adapter that is tapered or stepped and which is provided at its larger diameter end with an axial bore forming a sleeve adapted to receive the pin, and including fastener means for securing the adapter to the pin.

Further objects of the invention will appear as the description proceeds.

To the accomplishment of the above and related objects, my invention may be embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that change may be made in the specific construction illustrated and described within the scope of the appended claim.

FIGURE 1 is a perspective view of the sleeve extension adapter.

FIGURE 2 is a longitudinal sectional view thereof taken on line 22, FIGURE 1.

FIGURE 3 is a side elevational view showing the invention applied to a Bartell equipped truck.

Referring in detail to the drawings, FIGURE 3 shows at 10 a Bartell equipped lift truck designed to move printing paper rolls. The truck 10 is particularly employed to move such printing paper rolls which are stacked on end on the floor of a freight car, i.e., with the axis of the printing paper roll vertical, to a location removed from the freight car. The Bartell equipped lift truck 10 is pro vided with a substantially vertical frame 12 on which is suitably mounted for up and down movement, a support carriage 14. A hydraulic ram and control system (not shown) actuates the carriage in its up and down movement.

Carried by the support carriage 14 is a forwardly extending fixed cantilever boom 16 which is hollow. Axially slidable within the boom 16 is a depending pin 18, shown in dotted lines in FIGURE 3 as depending vertically and downwardly from the boom 16. A hydraulic ram (not shown) within the boom 16 is connected to the pin 18 to move the same towards or away from the support carriage 14. An arcuate skeleton cradle 20 is fixed to the support carriage 14 and is adapted to receive one side of a roll of printing paper.

It is to be noted that the pin 18 is short which is conventional in a Bartell equipped lift truck, the short length of the pin 18 being sufficient for insertion in the axial sleeve or core of the upstanding roll of printing paper of a normal width. Where, however, the rolls of printing paper are of a width considerably smaller than the normal width, the short length of the pin 18 cannot satisfactorily engage the axial sleeve or core of the (smaller) roll to move the same into the cradle 20 of the support carriage 14.

Accordingly there is provided a sleeve extension adapter 26 for use with the pin 18. The sleeve extension adapter 26 is at least 2 /2 times as long as the pin 18 and is shown in reduced

diameter sections

28, 30 extending axially from an upper sleeve section 32. If desired the sleeve extension adapter may be formed tapered with its smallest diameter end lowermost. The sleeve section 32 is formed with a cylindrical bore 34 of a diameter and length such as to snugly receive the pin 18. Adjacent the upper open end of the sleeve section 32 there is provided transversely aligned

bolt receiving openings

35, 36. The upper end of the pin 18 adjacent the boom 16 is also provided with a transverse bolt receiving opening.

In use the sleeve extension adapter .26 is fitted to the pin 18 by the reception of the pin Within the bore 34 of the sleeve section 32, and is secured to the pin 18 by the bolt 38 passing through the

bolt openings

35, 36 and the bolt opening in the pin. A nut 39 secures the bolt in place. Thus, the sleeve extension adapter 26 may be moved by manipualtion of the hydraulic controls into the axial sleeve or core of a roll of printing paper that is standing on end on a floor surface, and by further manipulation of the hydraulic controls the sleeve extension adapter 26 with pin 18 is moved towards the support carriage 14 so as to bring the roll of printing paper into a clamped seating engagement in the cradle 20. Elevation of the support carriage 14 on the frame 12 will then raise the roll of paper and permit transport thereof by the truck 10 to another location.

The lift truck and its hydraulic rams and controls forms no part of the present invention which relates solely to the sleeve extension adapter 26 and its application to the pin 18.

While certain novel features of my invention have been 3 shown and described and are pointed out in the annexed claim, it will be understood that various omissions, substitutions and change in the forms and details of the device illustrated and in its operation can be made by those skilled in the art Without departing from the spirit of the invention.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

1. For use with a Bartell equipped lift truck for transporting a roll of printing paper having its central axial sleeve vertical, there being a vertical pin carried by the truck for insertion into and engagement with said axial sleeve;

(21) An adapter comprising a rigid tapered bar element formed of a plurality of integral cylindrical sections of varying diameter having the larger diameter section providing the upper portion of the bar element and the smallest diameter section providing the lowermost portion of the bar element,

(b) a closed axial bore at the larger diameter end of said bar element snugly receiving said pin to locate the bar element in fixed coaxial relationship with said pin so as to provide an extension thereof,

(c) aligned bolt receiving openings in said pin and larger diameter end of said bar element, and

(d) a bolt extending through said aligned bolt receiving openings including a nut on the bolt for rigidly connecting the adapter to said pin.
