JAMES S. NELSON, OF SPRINGFIED, OHIO.

HAND-TRUCK.

SPECIPICATION forming part of Letters Patent No. 300,496, dated June 1'7, 1884.

Application filed March 19, 1884. (No model.)

Be it known that I, JAMns S. NnLsoN, a citizen of the United States, residing at Springfield, Clark county, and State of Ohio, have invented new and useful Improvements in Hand-Trucks, of which the following is a specification.

My invention consists in the combination, with a haggage-truck, of devices by which it may he easily and quickly converted into a step-ladder, the attachments whereby the double function is effected being` so constructed and combined with the truck that they shall not impair itsusefulness nor add materially to its cost.

It also consists in the combination` with the truck-frame, of fenders,whereby the Wheels are so far covered that luggage carried upon the truck will n'ot come in contact therewith, and which serve to give a broad base of support to the structure when the same is used as a stepladder.

My invention finally consists in the peculiar construction of the devices forlocking the supporting-frame in place, and in the several features of mechanical construction and combinations of parts hereinafter fully set forth, and definitely pointed out in the claims.

. Referring` to the drawings, Figure 1 is a perspeetive view showing my invention in position for use as a step-ladder. Fig. 2 is a perspective view showing the supporting-frame folded upon the truck-frame. Fig. 3 is a side elevatiou of the end of the supporting-bar, showing the manner of mounting the Wheels. Fig. -i is a detail perspective of a portion of the side rail of the truck-frame, showing the construction of the stop by which the spread of the supporting-legs is limited. Fig. '5 is a perspective showing a modification of the device illustrated inFig. 4.

In the drawings, the reference-number 1 indicates the truck-frame, having side bars, 2 2, terminating in handles 3 3. Upon the forward end of this frame is mounted the shovel 4, which is of the usual construction. The side bars, 2, are in the trueks in common use connected by rounds 5, and these may or may not be employed iu my invention hut in either case steps 6 are mounted upon said bars,whieh may not only serve to connect and brace the frame, but also serve the further purpose of Steps. Near the handle end of the truck-frame I pivot a supporting-frame, 7, consisting of legs or bars S, having` substanti'al parallelism with the side bars of the truck-frame 1. Upon the lower end of these hars I mount the truckwheels 9, their journals projecting outside the bars 8,' while the aXle is asingle shaft running transversely across the lower end of the supporting-frame 7 and coneealed within a sleeve, 10. The construction of the parts is such that when the frame 7 is folded upon the truckframe the bars 8 will lie outside and adjacent to the side bars of the truck, hriuging the Wheels beneath its forward end, in the manner shown in Fig. 2. Upon the side bars of the `truelgand covering the pivoted end of the supporting-frame 7, I place a metallic hood, 11. (Shownin detail in Pig. 4.) This hood consists of a A-shaped plate having its converging sides fianged inwardly, as shown at 12, and

provided with a'g'rooved braeket, 13, arranged transversely. The pivot-bolt 14 of the legs S passes throughthe upper part of this head, and it is so fastened to the truck-frame that it is rigid thereon. One of the fianged sides 12 is fiush with the side rail of the truck; and it will be seen that as the supporting frame 7 is opened its spread will be limited by the other diverging fiange. This affords a stop for the leg-frame. The braclret 13 projects inside the side hars of the truck-frame, and its groove receives the end of the upper step mounted upon said rails, giving additional support to it, and at the same time supporting` the hood against the leverage of the extended leg-frame.

By reference to Fig. 8 it will be seen that the lower ends of the legs 8 are rounded at the point 16, and the wheel-journal is located so far from the extremity that when in a Vertical or nearly Vertical position the wheel is raised out of contact. This gives the leg a firm bearing and avoids the danger and inconvenience which might result from having a mere rolling support. Upon the side hars of the truck, near their forward ends, I mount fenders 17, which proj ect over the Wheels, give a more extended support to luggage carried by the truck, and -prevent the Wheels from coming IGG in contact therewith, whereby their movement would be impeded and the baggage marred and inj ured. These fenders also serve the purpose of giving a broad base of support to the truckframe When the same 'is used as a step-ladder, as shown in Fig. 1, whereby swaying or side movement of any kind is effectually prevented; a Instead of using the hood 11, I may employ a bar or plate, 18, which is bolted to the rear edge of the side bar, 2, of the truck-frame, and having an arm, 19, bent rearwardly and at right angles, or thereabout,with the bar or plate 18. At the end of this arm is an arm or stop, 20, which proj ects laterally into the pathv the bars 8 of the supporting-frame I place a strong transverse brace, 22, tenoned into the bars just over the sleeve 10. This brace supports the truck-framewhen the parts are folded together, as shown in Fig. 2.

It should be noted, also, that the stops 6, although shown as being mounted upon the truck-frame 1, may be placed upon the supporting-frame 7, thus reversing the relative functions of these parts.

By this invention I provide a light, convenient, strong, and comparatively cheap structure, which is capable of the double use for which it is intended.

Having thus described my invention, What I claim isi' 1. The combination, with a truck-frame, of

legs or supporting-bars pivoted to the truckframe near the handles, and having the Wheels j journaled near their opposite ends, anda stop for limiting the spread of the supporting-bars, `substantially as described.

3. The combination, with a truck, of a pivoted supporting-frame, in the free end of which the truck-Wheels are journaled, Whereby the device may be used either as a truck or as a step-ladder, substantially as described.

4. The combination, With the truck-frame., of a stop for limiting the movement of the pivoted supporting-frame, said stop being provided with a groove or recess to receive and support the end of described.

5. The combination, with a truck-frame, of a pivoted supporting-frame carrying the truck- Wheels and fenders extending over said Wheels, substantially as described.

6. The combination, with a truck-frame, of a pivoted supportingframe having its free ends rounded or curved at an angle, and truck- Wheels journaled in said supporting-frame, the distance between their axis and the end of the support being greater than the radius of the wheel, whereby Vplacing the end of the bar upon the floor will remove the Wheels from contact, substantially as described.

7. The combination, in a hand baggage-truck, of a supporting-frame and a wheeled frame, the two frames pivoted together at or near one end, and one of the frames provided with Steps to produce a combined baggage truck and step-ladder, substantially as described.

In testimony whereof I have affixed my signature in presence of two witnesses.
