GEORGE H. SPENCER, OF CHICAGO, ILLINOIS.

APPLIANCE FOR To all whom it may concern.-

Be it known that I, GEORGE H. SPENcER, a citizen of the United States, and residing at Chicago, Cook county, State of Illinois, have invented certain new and useful Improvements v in Appliances for Handling Ti ber, &c., of which the following is a specification. I H The present invention relates to improvements in means for handling timber, metal beams, tubes,'rods, etc, and particularly to a device adapted to be employed in loading such material into or unloading it from box cars.

1 The object of the invention is to provide adev-ice or means of simple and strong construction by the assistance of which material of the character referred to can be shifted from or into a car, or onto or from a pile or stack, with a minimum amount of exertion or manual labor. a

form, and a threaded member B engaging a thread within the upper end of the member A, by means of which the standard is extensible so that it mayextend continuously from the floor to the top of the framejof the doorway of the'car. At its upper end the extensible section Bis provided with a head C adapted to be engaged by asuitable tool or bar by which the threaded section may be turned so fthat said head'will be brought into such contact with the top of the door-way as to securely retain the standard in desired position. Any suitable foot or base may be provided for the member A, or in some instances the same may contact directly with the floor or bottom sill of the doorway. However, as shown it is preferred to employ a sectional base comprising two similar members D adapted to closely surroundthe lower end of the standard A, sald members being connectedby bolts E by means of which they may be drawn closely together so as to firmly engage the tube A and form a rigid, solid foot therefon To permit of readily disconnecting such base or foot from the standard, one of the connecting bolts may be provided at one end with a handleF. i h V A sleeve G is fitted to the standard A in such a manner that, except when locked thereto by means to be hereinafter described, it, may freely rotate aboutjsaid standard as an axis. In the form of the device illustrated, this sleeve comprises a body portion of relatively light material having reinforcing end sections H, H'snugly fitted therein.- The lower end of said sleeve rests upon the base or foot D. ofsthe standard andthe upper section Hfiis projected beyond the body G and provided at its upper endwith a series-of notches or teeth, withwhich', are engaged similar teeth -formedona short sleeve I that loosely surrounds the standard A.v Tothe standard Aabove said sleeves is clamped a collar K similar in construction to the base or foot member D provided with a handle'K, by manipulating whichit may be closely clamped to the 1 standard or loosened so as to be freely adjustable longitudinally thereofQ At its lower end, said collar is provided with a notchorrecessk and a key L is adapted to extend into said notch, and-a. seat formed in the sleeve 1, as shownin Figs. 3 and 8. When the collar K is tightly clamped to the standard A, and

the key L positioned so as to engage the notch 70, it will be seen that the entire sleeve hereinbefore referred to will be locked to the standard and prevented from any movement relative thereto. .By operating the readily turned about the standard as an axis to position the material supporting rollers hereinafter referred to at the desired angle relative thereto. The parts can be quickly locked in the adjusted position by moving the collar K into engagement with the key L and operating the handle or lever K so that said. clamp is again secured to the standard.

The sleeve before referred to is provided with means for supporting the roll or rolls over which the material to be loaded intothe car, or unloaded therefrom, can be readily passed.

In the drawings two-forms of such roller supports are illustrated. Referringparticularly to Figs. 1 and 2, it will be seen that the sleeve is provided adjacent its lower end with means forsupporting. two substantially horizontal parallel rollers M. The support 9 for said. rollers includes a. baseplateN which is formed integral with, or suitably attached tov one-half of .a. sectional clamp 0 adapted to be secured, as. by suitable bolts, to. the lower end of the sleeve G. From the plate N.

5 extends a bifurcated arm P, the. free ends of. which are bent upward. and formed with bearingsto receive. the pintles or axles ofthe supporting rollers M, suitable bearings for the opposite. ends of sa d pintles being pro- I ,0 vided in the plate. N. As shown, the rollers M are preferably made slightly concave. in

' form and they areso. adjusted with relation tothe vertical axis of the standa-rd A as to be equidistant therefrom so that the weight 4.5 of the.- timber, metal bar, tube, etc., resting thereon will not produce an unequal strain on the standard, Thesleeve G may also be provided-with a roller Q mounted in suitable bearings. on a laterally extending arm that D is provided at its inner end with means for clamping it securelyto the sleeve. Preferably, asshown, the arm, Ris additionally supported by a brace S extending from a collar clamped about the sleeve. As shown 5 in Fig. 1, both sets of rollers M and Q, may

be employed on a single standard, the lower one being used until the pile or stack within the car has reached a certain height, if the 7 device is employed in loading, and the roller Q being used subsequently or vice versa. It

will also be seen that the sleeve and rollers supported thereby may be adjusted to any desired vertical position on the standard. That 1s, the base member D. may be adjusted at vertically on the standard and secured at any heightiso that the sleeveresting thereon will bring the rollers into" the desired horizontal plane.

A device. such as hereinbefore described may be employed in connection with a stock or horizontal supporting device adapted to be positioned horizontally across the doorway. Such an arrangement is illustratedtin F 4, and 5. Referring to these figures, it will be seen that the stock consists of two side bars T which are connected adjacent theiriends by tie boltszj and at one. end there is secured between said bars an internally threaded block T; with, which engages a threaded stem T that is provided, at its outer end with a head having-means for engaging. neotthe side. chambers of thedpor frame." At the other end the plates: or -side members T are provided with teeth, adapted toengage the adjacent j amb of the door-way so that the device can be. firmly secured in the opening. at any desired elevation from the fleor. The, parts I areso positibned that the standard A and sleeve G thereon can pass between them. and the roller Q will-, be situated some; distance above, the s'toclrT. Such anarrangement as shown, in Figs. 4 and. 5 particularly useful in load-ingfand unloading. cars of lumber where the work man eansuccessively withdraw from] the pile or stack a. series of beards, for example, i

and position same alongthe stock that thennmber, size, etc., thereof can; be readily computed by a clerk, i

In some cases, the material supperting roller may be mounted directly on the stoek T. Suclran arrangement is shown, in Fig. 6, in whichit willbeseen. that theroller Q is mounted on a carriage U eonip rising. top and bottom members engaging the. plates or ba I d a apt d to e heldr y at y desired position thereon by means of a threaded stem, V and hftlldjlQ W. By this ar- 7 rangement, the supporting roller can be adjusted practically throughout thewidth of the door-way 'asthe conneeting. rods or tie members 25 are so separated, that they do not interfere with the maximum ame n of said roller support. i i

It is believed that the manner of using and many of the advantages possessed by aldevice constructed in aecordance with k the pre e ve tio i l be eadily nd steed from the, foregoing descriptron and the dr n I v be's e at he d i comprises very few parts and these are so assembled as to provide. a very strong and durable. structure Owingto thefactthat the material supporting roll or rolls maybe adjusted, about vertical axis, the device en ables workmen to readily unload long, heavy pieces'of timber or metal from a' car directly on to, a wagon standing at the side, of the car, or vice' versai Fig. 2 'shows that the rollers may be'turned' so, as to. lie substam rec tially outside of the side lines of the car, or entirely within the car body, as may be required in manipulating the material to be moved.

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

1. A device for the purpose described comprising an upright or standard, a sleeve rotatably surrounding the standard and provided with means for supporting a substantially horizontally arranged roller, a collar secured to the standard beyond one end of the sleeve, and means connecting the sleeve and clamp to lock the sleeve against movement about the standard.
