Y Application filed November 13, 1896. Serial No. 611,977. (No model.)

To a/ZZ whom it may concern:

Be it known that I, GUsTAF A. DAHLBERG, a subject of the King of Sweden and Norway, residing at New Sweden, in thel county of Nicollet and State of' Minnesota, have invented certain newl and useful Improvements in Hand-Carts and I do declare the following to in section.

be a full, clear, and exact description of the invention, suchas will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference 'marked thereon, which form a part of this specification.

My invention relates to improvements in carts of the class used especially by farmers and gardeners and are provided with attachments by which they may be'converted into modified shapes, making them adaptable for various kinds of work.

The objects of my invention are, first, to provide a twowheeled hand-cart which may carry a roll of fence-wire or a barrel or similar vessel for hauling water or anything else put into in; second, to lprovide a hand-cart which will automatically roll wire on and off its wire-reel by the motion ofthe cart and in rolling up the wire spreads it on the reel; third, to provide ahand-cart which may easily be converted into a horse-cart and drawn or pushed by a horse or mule These and other minor objects I attain by the novel construction and arrangement of parts illustrated in the accompanying drawings, vin which- Figure 1 is a top or plan view of my hand-cart with a`wire-reel mounted on it. Fig.4 2 is a side view of Fig. 1 with one of the ground-Wheels removed. Fig. 3 is a front view of one of the brackets 3. Fig. 4.is a left-hand side view of Fig. 3. Fig. 5 is a perspective view of the frame-bar 4, which in Fig. 1 is secured between the brackets 3. Fig. 6 is adetail front view of a -portion of Fig; 1 with the pinion 19 Fig. 7 is a sectional right-hand side view of Fig. 6, as on the line a, a, with the parts 20and 21 left out and the brace 48 added. Fig. 8 is a rear end elevation of the cart as it appears when converted into a vessel-carrier for water, &c.

Referring to the various parts in the drawings by reference-numerals, 1 designates a pair of carrier-wheels or groundwheels which revolve uponthe journals 2, projecting outward from the two brackets 3, which are secured together by the horizontal transverse frame-bar 4 and bolts 5, passed through the flanges 6 of the brackets 7 of the frame-bar. The brackets 3 are further secured together by the arms 13and handle' 14, and the tube or hollow bar 8, passed through and being secured in the brackets 3 by the pins 9, inserted through pipe and brackets, as shown in Fig. 1.

When the cart is used .with the barrel 10 on it, the bar 4 is removed, the frame in- Verted, as in Fig. 8, and the remaining transverse frame-bar 8 forms a support for the vessel 10, which is further held in place by the side handles 11, secured on lit and embracing the projections 12 of the brackets 3.

When the vessel is not needed, it is simply lifted out of the frame, the latter returned to its normal position, and the cart is converted into a fence-wire collector, carrier, and distributer, as will now be described.

The pins 9 are removed from the brackets 3 and the wire-reel 16 secured by the pin 9X kupon the bar 8, which is therebyconverted into a revoluble shaft revolving in the brackets 3 and carrying the Wire-reel'between the brackets, while beyond one of the brackets one of its ends has secured to it a collar or clutch member 17 (see Fig. 6) with corrugations 18 upon its outer end, with which engages the corrugated inner end of a loose collar 19, which is held in operative but yielding contact with the collar 17 by the spring 20, to which more or less tension may be given by the thumb-screwl 21, passing through the spring and being screwthreaded into the bracket 3. The loose collar or member 19 of the friction-coupling thus formed is provided upon its periphery with sprocket-teeth 22, which engage a belt-chain 23, driven by the sprocket-wheel 24, secured upon the innerv side of one of the ground-wheels, so as to revolve with it and drive or revolve the wirereel.

The inner side of the sprocket-wheel 24 is provided with spiral-shaped grooves or threads 25, engaging the teeth 26 of a horizontally-placed cog-wheel 27, revolving on a stud-28, secured in the bracket 29, projecting almost horizontally from the frame-bar 4, to which it is secured at 30. (See Fig. 5.)

To the bar 4 is further pivoted at 31 the horizontally-swinging arm 32, which is connected by the pitman 33 to the crank-pin 34, secured in the wheel 27. The free end of the arm 32 is formed with a head 35, carrying four friction- rollers 3G, 37, 38, and 39, between which the wire 40 is guided olf and onto the reel.

The spring 2O has its upper end held in position by a cavity 41 (shown in Fig. 6) inthe center of the pinion 19.

42 is a pawl pivoted at 43 to one of the frame arms or brackets 3 and engages normally the ratchet-teeth 44, provided upon the circumference of the clutch member 17, thereby preventing the reel from unrolling the wire when the latter is to be stretched by the cart. Then it is desired to liberate the reel from the pawl, the latter is swung out of engagement with the ratchet-teeth and kept in that position by the engagement of the spring 45 with the projection4 46 near the front end of the pawl.

The arms or shafts 13 are pivoted at 47 to the brackets 3 and are further braced thereto by the oblique braces 43,pivoted at 49 to the shaft and at 50 to the bracket 3. The end of the brace pivoted to the bracket is provided with a series of holes 51 52 53, by which the brace may be shortened or lengthened, thereby regulating the height of the shafts 13 and handle 14 to any desired or convenient position.

lVhen it is desired to move the cart by horse-power, the detachable shafts 54 are secured by bolts, as 55, to the main shafts 13, as shown in dotted lines in Figs. 1 and 2, and the tugs of the harness are secured in the holes 57 of the detachable shafts.

In operation it has already been stated and shown in Fig. 8 how the cart is used as a Water cart or carrier in general and how it is differently rigged as a wire-cart. It will be further observed that when the cart is moved either by hand-power or horse-power the ground-wheel secured to the spiral-grooved wheel 25 causes the latter to revolve, Whereby the chain belt 23 Adrives the wire-reel 16, thereby winding upon it the wire in taking down fence-wires, dto. Should the reel re- .volve too fast for the motion of the cart,

I use a certain kind of reel for the cart; but common reels of various lengths on which the fence-wire is sold in the market may be used, when so desired, and the stroke of the arm 32 may then be regulated by moving the crank-pin 34 into the various holes 26X in the wheel 27. When the cart is to be changed to a water or vessel carrier, the spring 20 is sprung with its upper end out of the cavity in the clutch member 19, swung on the screw 21 out of the Way for the shaft 8, which is then, after being released from the reel by removing the pin 9X, pulled out of the brackets 3 and returned after removing the reel, the clutch member 19, and the spring 20. The removal of the frame-bar 4, the inverting of the frame, and placing of the vessel have already been described.

What I claim as new, and desire to secure by Letters Patent, is-

1. A combined hand and horse cart, having detachable shafts for the horse, adapted to be readily attached to the shafts used for handpower, substantially as set forth.

2. In a wire-cart, the combination with a pair of ground-wheels, axle and frame carried thereby, a wire-reel mounted on the frame and operatively connected with one of the ground-wheels, a shunting-lever pivoted in the frame and carrying at one end rollers for guiding the wire onto the reel, a pitman pivoted to said lever, the crank-wheel 27 operating the pitman and having teeth upon its periphery and a spiral-toothed wheel engaging said teeth, and being secured vto one of the traction-wheels, is thereby revolved, and operates the shunting-lever, substantially as set forth.

3. In a hand-cart the combination of a pair of ground-wheels, a frame carried thereby, a wire-reel mounted inthe frame and a swinging arm for guiding the wire onto the reel, said arm being provided with four frictionrollers or guiding-sheaves between which the wire passes, and means for swinging the arm by the revolving of one of the ground-wheels, substantially as shown and described.

4. A hand-cart having a pair of groundwheels and a frame carried thereby, and a pair of shafts projecting from the frame and connected together by a handle as 14, said shafts being adjustably secured to the frame, so that they may readily be raised and lowered relatively to the frame, by the extensible braces 4S, substantially as and for the purpose described.

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