To all t may concern.'

Be it known that I, OT'ro L. E. WEBER a citizen of the United States resident of St. Cloud, county ofv Stearns,- State of Minv nesota, have invented certain new and use ful Improvements in Trucks, of which the following is la specification. h

The object of my invention is to provide a truck designed particularly for handling roll paper to the end that a large amount of manual labor may be avoided, railway 'cars v may be easily and quickly loaded to their maximum capacity and the rolls stacked on end one upon another and thereby protected from damage. l Other objects of the invention will appear from the following detailed description.

The inventionv consists generally in various constructions and combinations, all as hereinafter described and particularly pointed outin the claims In the accompanying drawings forming part of-'this specification,

Fig. lO'is a section on theline lO-lO of Fig. 9.. In the drawing, 10 'represents the horizontalframe or base 0f -the truck having the truck wheels 11 and a platform 12. The

'.motive power for the truck is preferably furnished by a storage battery and electric motor (not shown) but mounted on the rear end ofV the platform '12 within inclosures 13 Specification oi Letters Patent. `Patentd May 10, 1921" Application filed May 8, 1919. Serial No. 295,770.. v I v and 14 respectively. A'switch 15 may be arrangedrconveniently for starting and stopping the motor and wires .16'connect the battery with the motor.

' lhe hoisting drum 17 'ismounted on standards 18 upon the platform'12 and isdriven from the motor by means of a pinion 19 on the motor shaft 20, a gear 21 on a shown included in the electric circuit.

The hoisting frame preferably consists of upright bars 26 having channels rigidly secured to the base 10 at 28 and further fastened by braces 29 and 30. The channel bars 26 are connected at the top by a transverse yoke 31 which prevents spreading of the bars and at the same time aifords room for the passage of the hoisting carriages. An auxiliary hoisting carriage, comprising the `vertical channel bars 32, the lower

horizontal cross bars

33 and 34 and the upper cross bar 35 is arranged to slide in the channels 27 of the bars 26 and a main hoisting carriage 36 has lguide rollers 37 adapted to .travel in the channels 38 of the bars 32.

Sheaves 39, 40 and 41 are mounted in the carriage '.36 and sheaves 42 and 43 are mounted respectively in the lower cross bars 34 and upper cross bar 35 of the auxiliary carriage. A sheave 44 is arranged centrally in the yoke 31 and a chain or cable 45 passes from the hoisting drum 17 over this sheave then under the lower sheave 42 and up over the upper sheave 43 and then down under the

sheaves

39 and 40 in the main carriage as shown in Figs. 1 and 4. A hook 46 is secured to the end of the cable 45 for attachment to a clamping strap 47 as shown 'eled block 55, preferably by means of dovetailed or slotted grooves in the block in which the tongues 56 of the cradle enters, the cradle restin r against a suitable stop as at 57. (See Iligs. 3 and 5.). The swiveled block 55 forms a part of the hoisting carriage 36l and is mounted in an annular opening in the center. of the carriage and rotatably supported by means of the interlocking annular flanges 58, 59 and 60. The sheave 39 is mounted in the main carriage and the'sheave 40 in the block 55, and the location of the sheaves is such that the cable 45 passing under both sheaves is directl in the center of rotation of the block.

yhe sheaves

39 and 40 are used only When handling rolls in the horizontal position or up-endino' the rolls as indicated in dotted lines in Fig. l, but when rolls in a vertical position are to be handled, as when loadlng cars, the cable is removed from the

sheaves

39 and 40 and brought under the sheave 4l at the top of the auxiliary frame and the hook 46 is attached to the clamping bar 48 Fig. 6. This bar is provided with a downwardly turned arm 61, adapted to enter the core opening in the roll, and slides horizontally in suitable guide ways 62 on a plate 63, that is detachably secured to the cradle arms 52 as by lugs 64 and screws or pins 65. (See Fig. 6.) The plate 63 is removed and a strap 47 is attached to the rod 53 of the cradle arms 52 when the rolls are to be handled in a horizontal position. The strapbeing stretched out upon the ground, the roll is rolled over it, after which the strap is brought around the roll and attached to the hook 46 as illustrated in Fig. 4. The motor is then started.

to rotate the drum 17 and as the slack of the cable is taken up, the roll is drawn tight against the cradle arms and a continuous rotation of the drum causes the main carriage 36 to rise in the auxiliary carriage. When the roll has been raised sufciently from the ground, as in Figs. 1 and 2, and if it is desired `to up-end the roll the motor is stopped and the roll is swung around with the swiveled block to a vertical position, after whichI the motor is started in the reverse direction to let the,

roll down on the ground. If it is desired to double deck the rolls with the upper roll horizontal as in Fig. 8, thehoisting drum is kept rotating until the main carriage engages the upper cross bar 35 of the auX-' iliary carriage as by the lugs 66 striking the cross bar at 67, when continued hoisting causes the two carriages to rise together in the channel bars 26 to thel desired height, after which the roll 50 may be let down on top of the vertical roll 50a. As the cable slackens the hook 46 is automatically released from the strap 47, and the' truck may then be moved on its wheels 'and the cradle lowered for raising another roll. For vertical handling or double tiering-rolls in the vertical position, as in Fig. 7, the strap 47 is removed and the plate 63 and hook 46 are attached as heretofore described, the

/carria e is hoisted to the ro er )osition with respect to the roll, as 1n fig. 5. The 70 carriage is then lowered to drop the clam .bar 48 into the core opening 5()b as indivproper and the hoisting device, I prefer to construct the clam bar 48 as shown in Figs. 9 and 10. `his clamp is providedv with a slotted core plug 68 and horizontally adjustable on the bar 48a by means of a slot 69 and secured by a bolt v70. At its inner end the bar is also provided with a transverse notch 71 into which a locking finger 72 of a pivoted latch 73 is adapted to enter for the purpose of temporarily locking the bar against movement, while the plug 68 is inserted into the core opening ofthe roll. l The latch 73 is disengaged from the notch 95 71 to allow the bar to be moved lengthwise to draw the roll against the cradle at the be inning of the hoisting operation.

t is evident that the cradle orsaddle 51 may be easily detached from the carriage block 55 and other forms of carriers substituted therefor to adapt the truck for handling crates, bundles or packages of different kinds.

I may partially counter-balance the weight of the roll on the forward endA of the truck by means of the battery and motor at the rear end, but other counter-bal-v ancing means, not shown, may beused. It.

is evident that the hoisting drum may be of 11o any suitable type'and its operation may be` performed in various ways and many changes and modifications may be .made in the details of construction without alteringl the principle or scope of theinvention` do-not, therefore, confine mysel-ffato thep'ar` ticular construction herein shown`.,-
