Our invention relates to improvements in trucks for handling rolls of news print-paper. Rolls of print paper are quite heavy and I are subject to considerable damage because of the several handlings necessary before they and it is the object of the present invention are mounted in a press for use.

These rolls must be delivered to newspaper plants; unloaded, and frequently taken into the basements of.the printing oflices; then moved to a place of storage where they are up-ended, because they require less space when standing on end; then when needed, the rolls must be placed on trucks and moved to the press where they are removed from the hand trucks, placed upon spindles and hoisted in place on the ress.

These several andlings of each roll of paper, and particularly when turning them from a horizontal to a vertical position, or vice versa, subjects the rim-edges of the rolls to bursting strains, and frequently tears numerous wraps of paper on the rolls, which torn wraps are useless and become a waste. Thousands of dollars are lost each year as the result of the damage above referred to,

to facilitate the handling of these heavy rolls of paper and to reduce the damage to the same when handling.

With-this object in view, the invention is illustrated in the accompanying drawings,

wherein,-

Fig. 1 shows the truck in side elevation and engaged with an upright roll of paper.

Fig. 2 illustrates the truck and paper roll thereon in side elevation and the truck part- J ly lowered.

Fig. 3 shows the same but with the truck I and paper roll completely lowered.

Fig. 4 illustrates the truck in longitudinal sectional elevation and in the partly lowered position.

Fig. 5 shows the truck in top or plan view. Fig. 6 illustrates the cylinder and piston in cross-section to show the ports therethrough, and v Fig. 7 illustrates the piston in rear elevation with the quick acting ports therein indicated by broken lines.

, Referring to the drawings, the numerals 10- and the foremost cross-bar is preferably provided with a toe-plate 12 for insertion be- .neath the roll.

Each side bar is of the angle-bar form and has a down-turned flange 13 extending longitudinally along its inner side.

The cross-bars 11 are preferably concave across their upper sides whereby to receive the rounded circumference ofthe rolls and hold the latter from rolling laterally from the bed of the truck.

The truck proper consists of two front linkbars 14 and 15 and two rear link- bars 16 and 17 ,the rear ends of the link- bars 14 and 15 lapping the forward ends'of the link- bars 16 and 17 and both sets of bars being pivotally mounted on the outer. ends of a cross-bar 18 which extends horizontally through the downturned flanges 13-of the truck-bed.

The horizontal cross-bar 18 therefore forms a pivot on which the lapped ends of the front and rear link-bars are mounted and also pivotally connects those la ped link-bar ends with the truck-bed. (lbtter-pins 19 are passed through the ends of the cross-bar 18 and serve to retain the lapped link-bar-ends on the ends of the cross-bar.

The forward ends of the front link- bars 14 and 15 are pivotally sustained on a front shaft or axle 20, while the rear ends of the rear linkbars 16 and 17 are pivotally mounted on the opposite ends of a rear shaft or axle 21.

Wheels 22 are provided on the opposite ends of the front axle while similar wheels 23 are provided on opposite ends of the rear axle 21.

A cylinder 24, has arear head 25, with an enlarged lug 26 on the outer side thereof and this lug has a horizontal passage therethrough so that the rear axle 21, may extend horizontally through the lug and sustain the cylinder in a horizontal plane.

In order to center the lug 26 of the cylinder on the rear axle 21, we provide the latter with spacing sleeves 27 which space the lug centrally between the rear ends of the rearlinks.

' ery and one side,

A piston 28 is located-in the cylinder and has a stem 29 which extends throu h a stufling-box in the forward head 30 an the forward end of said stem carries a block 31 which is mounted on the front axle 20.

It will therefore be seen that the cylinder 24 has its rear end sustained on the rear axle 21 while the forward end of the piston-stem 29 is attached to the front axle 20 so that when the link- bars 14, 15, 16 and 17 are spread out into a substantially horizontal position, as in Fig. 3 of the drawings, the piston-stem 29 will be drawn out and the piston 28 will then be at the forward end of the cylinder.

When the piston has thus been drawn to the forward limit of its stroke however, the weight of the bed is not placed on the pistonstem, cylinder and cylinder-head because we provide each of the two rear link- bars 16 and 17 with rollers or wheels 32, which are of a greater diameter than the wheels 20 or 21 and are so mounted as to take the weight of the load so that said load may be balanced on said larger wheels by a slight pressure on one end or the other of the truck.

By reference, particularly to Figs. 4 and 5 of the drawings, it will be noted that a tie-rod 33, extends horizontally between and connects the two rear link- bars 16 and 17, while a similar tie rod 34 extends horizontally between and connects the two forward link- bars 14 and 15.

It will also be noted that the downturned flange 13 of the angle-bars of the bed carries 8. depending plate 35, whose lower ortion is provided with a slightly elongated perforation 36 through which the tie-rod 34 extends so that the bed of the truck is maintained in substantially a given relative position with respect to forward link- bars 14 and 15, and even though the bed may be unbalanced by the weight thereon said bed cannot tilt independently of the link- bars 14 and 15.

It will further be noted that the flanges 13 of the angle-bars have bottom-edge notches 37, which, when the links are in their lowermost positions, will seat around the upper surface of the rear tie-rod 37 and serve as a stop to limit the spreading movement of the links.

The piston 28 controls the movement of the links through the passage of oil which must pass from one side to the other thereof, and this control is designed to permit a rapid upward movement of the links and bed but allow only a retarded movement in a downward direction.

The construction for effecting these fast and slow movements will now be explained, reference being made particularly to Figs. 6 and 7 of the drawings.

The piston 28 has a rigid center disk 38 with a cup 39 enclosing it around the peripha disk of flexible material through all of the onto said end.

A small vent passage is provided disks and the cup which passage is always open, and the disks 38 and 41 and the cup are each provided with ports 46 which are in register but over which the flexible disk 40 seats.

Obviously, when the piston rod 29 is pushed in, as it is when the bed of the truck is being raised, it is desired that the movement be rapid and quickly effected, and as this movement takes place, the piston will, of course move to the left and oil will rapidly pass through the large ports 46 and simply unseat the flexible disk 40.

When however, the truck-bed is elevated the piston will be located at the left end of the cylinder and the bed can be lowered only as fast as the oil can pass through the small vent passage 45, because the oil will be compressed against the flexible disk 40 and securely seat it over the larger ports 46. Therefore the bed will be checked in its descent.

We have found in practice when handling long rolls of paper, and most of them are long, that the end of the roll will project be yond the end of the bed and it is not convenlent to lift the bed with the roll thereon. We have therefore provided a pivoted handle structure whose inner T-shaped end 47, is

ivotally mounted on the horizontal cross- Ear 18 and this structure has a tubular bar 48 which extends rearwardly and has a collar with an eye 49 therein at its outer free-end. A clip 50 on the end sta -bar 11 of the bed will normally hold the tu ular bar.

On the interior of the tubular bar, we provide a telescoping rod 51 which may be extended so as to project outwardly beyond the end of the paper roll 52, when desired.

Another function of the rod 51 and pivoted bar 48 is to assist in turning an up-standing vertical roll of paper over and onto the bed of the truck, as will presently be explained.

We also utilize a flexible means in conjunction with the handle to facilitate the tilting of a paper roll from its vertical to a horizontal position. This flexible means consists, in this instance, of a chain 53, having a hook 54, at one end thereof for engagement with the eye 49 on the tubular handle 48,-the chain being attached to a belt or web 55 which may extend over the rim-edge of the paper roll, as shown in Figs. 1 and 2, without marring or damaging the paper wraps at said edge, and the other end of the web being attached to a pin or plug 56 which is inserted in the tubular core 57 about which the aper is wrapped'in forming the roll.

hen the roll of paper 52 is standing on end as shown in Fig. 1, the same is tllted slightly to permit the toe 12 of the truck-bed to be inserted thereunder. The pin or-plu 56 is then inserted in the tubular core 57, an the hook 54 on the chain 53 is eng ed with the eye 49, on the end of the pivote tubular bar 48.

The telescoping handle-rod 51, having been drawn out of the tube 48, is then grasped and pulled down, swinging on the crossbar 18, while the bed of the truck remains in an u wardly-inclined position.

As the han le-bar 51 is swung down the paper roll 52 is tilted over, as shown in broken lines in Fig. 1, until it drops against the inclined bed and as the weight of the roll is transferred to the bed the latter begins to swing down because the weight will s read the lower ends of the link-bars apart.

his spreading of the link- bars 14, 15, 16 and 17 can only take place as fast as the oil in the cylinder can flow through restricted passage 45 of the piston as the latter and its stem 29 can move in the cylinder because the piston-stem 29 has its forward end attached to the shaft or axle 20 to which the forward ends of the link- bars 14 and 15 are also attached.

As the bed settles down to a substantially horizontal position the large wheels 32, will seat on the floor and the flanges 13 of the angle irons of the bed will rest upon the tie-bar 33.

When the bed has completely settled down, the truck will be supported mainly by the large wheels 32, and may be readily rocked thereon to lift either the front or rear end which enables the truck and roll thereon to be readily turned around end-for-end to move it wherever it is desired.

It has hereinbefore been explained that the bed cannot swing independently of the forward links 14 and 15 because of the plates 35 and their engagement with the tie-rods 34.
