MERCHANDISEJ-IANDLING APPARATUS' Application filed July 6, 1923. Serial No. 649,833.

To aZZ whom z't may concern.

Be it known that we, GEORGE A. JOHNSTON and FRED A. BoALns, citizensof the United States, residing at Portland, in the county of Multnomah and Stateot Oregon, have invented certain new and useful Improvements in Merchandisellandling Apparatus, of which the following is a specification.

This invention relates to an apparatus for moving a body from a vertical to a horivide a device of this character including supporting rails, a carriage to receive the body to be handled and movable on the rails and arranged to be tilted relative to the rails,to transient-he body from a. horizontal to a vertical position or from a vertical to a horizontal position.

Another object of the invention is to provide a device of this character including supportingrails, a carriage to receive the body to be handled and movable on the rails and'arranged tobe tilted relative to the rails, to transfer the body from a'liorizontal to a vertical position or from a vertical to a horizontal position, and with means whereby the movement of the carriage is controlled. With these and other objects in view, the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed outin the claims, and in the drawings illustrative of the preferred embodiment of the invention Figure l is an end elevation of the improved apparatus.

Fig. 2 is an enlarged plan view of the movable carriage with a portion broken away to show the structure of the guide rails and rollers. i Fig. 3 is a side View ofthe parts shown in Fig. 2, with portions broken away and with the main support in section on the line 33 of Fig. 2. I I I Fig. 4 is a detail on a reduced scale, illustrating the arrangement of themotion controlling combined air cylinder and spring.

Fig. 5 is an end elevation of the parts shown in Figs. 2 and3.

-Fig. 6 is a transverse section on the line 6'6 of Fig. 2, looking in the direction of I the arrow. 1 I

F 1g, 7 is an enlarged sectional detail of a portion or" the combined air cylinder and spring. I r The-improved apparatus may be employed in connection with a storage platform, a vehicle or truck, or the like, and adapted to handle various arti'cles, but is designed more particularly for handling large rolls of paper such as used by newspaper publishers and the like, and for the purpose of illustration is shown in Fig. 1, applied to a conventional truck'device, for transporting rolls of paper oi this'cla'ss, but it will be understood that it is not desired to limit the invention in any manner to the location of the'lowering and elevating device.

The improved apparatus includes spaced supporting members 10 which may be the side rails of a truck as representedin Fig. 1.

Rigidly attached to the upper faces of the side members 10 at some points thereon are spaced supports 11, of hardwood or metal as may be preferred and preferabliyextending at the ends beyond the members 10, as shown in Fig. 1.

Bearing upon each of the supports 11 is a guide rail 13, preferably of sections of I- beams as shown in Figs. 5and 6, and rigidly secured by any suitable means to the sup-i ports '10. 1'

By thismeans upwardly opening guide channels are presented extending in parallel spaced relation, as shown in F igs. 2, 4, 5 and 6. Extending between the uide rails 13 and mounted for rotation relative thereto therailsl is cut away as shown at 15, and i the axle 16 of the endroller 14 extends through the flanges of the rails and transversely of the recesses or cut away portions 15, theportions of the axle 16 between the sidles of the channelled rails. forming stop ro s.

Movably disposed upon the bearing rollers 14 is a carriage orcar to receive the body to be handled, andconsists of a base plate 17 with spaced bearing strips 18, beneath the side portions and bearing directly on the rollers 14, as shown in Figs. 3, 5 and 6.

against the outer tacesof the L-bars d opera-tes.

Attached, to the upper face of the plate 17 at the edges are L-bars 19, and bearing over the L -bars is a flcor member including ddtviituiii ed side 'p'ortioi'i's '20 bearing 19 and with the intermediate portion curving downwardly between the members 19, as, shown in Figs. 5 and 6.

a. 1 Attachedto the floor meinber at the tail 10 end is stop member :23, for illustration formed of a section of an L-bar as shown in eto a ,A ,a,cfhed to, thejlojiverfaces ot the hearing members 18 intermediate the ends and depending into the channel portions oi the guide rails 13 ,are open'stop hooks 2 1;ada-pto ;e'd ;t.o engage the stop rods 16 when the carrija' ejis moved into tilting position, and at ,1 tab edto the lower faces ofthe members 20 P18 atrthejfend farthest from the stop rods -:1 6,:are sfops 25,,operatin'g toprevent lateral displacement Oi the carriage.

but it the tracks re locat'edtat 118' the "of the members 10, then the load v vill be rolled in one direction only to the carriage.

If thestoragerplace for the elevated'rol1s is a Warehouse or the like, the/members 10 .Will erely e at s k o} supp rt. t rolls, or other object elevated by the coac'tion of the tracks and carriage.

The preferred embodimentof the invention is disclosed in the drawings and 'set forth in the specification, "but it lvvillfi be understood that modifications vvithin fthe scope of the claims may be-madein the construction Without departing from th'evprinci- =ple of the invention or sacrificing any of its advantages. 4 p

Having thus described the invention, what is claimed as new is l p 1. In an apparatusoi' the class described, guide rails in spaced ,parallel relation, said rails being formed vithupvvardly; opening longitudinal channels, stop rods extending transversely of the; channels of said'iguide 1 aw i e ora leo mera ds and open hooks attached tofsaid carriage intermediate the jends thereot and depending into the channels of the rails and fguidin-g the carriage relative thereto and' 'adapted to engage the stop rods of the guide rails when the carriage is moved into a predetermined position to enable the carriage to he tilted toward a vertical position.

2. In an apparatus of theola-ss described, guide rails in spaced parallel relation and formed of channel IDQHIlJGIS'WltlI the side webs extended beyond the bottom Web, stop rods extending through the extending side Webs of the guide rails, a carriage movable on said rails, and open hooks attached to said carriage intermediate the ends thereof and depending into the channels of therails and guiding the carriage relative thereto and adapted to engage the stop rods of theguide rails and extending into the cavity formed by the extensions of the side Webs When the carriage is tilted toward a vertical position.

In testimony whereof, We afiix our signatures hereto.
