HAY-CARRIER.

SPECIFICATION forming part of Letters Patent No. 340,923, dated April 2'7, 1886.

Application tiled January 522. 1886. Serial No. 189,369. No model.)

T @ZZ whom it may concern:

Be it known that we, JAMEs WHITE PRO- VAN, of the town of Oshawa, in the county of Ontario, in the Province of Ontario, manufacturer, and JOHN WHITE PnovAN, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, salesman, have jointly invented certain new and useful Improvements in Hay-Carriers, of which the fol- Io lowing is a specification.

The object of the invention is to design a simply-constructed hay-carrier, preferably reversible; and it consists in the formation and arrangement of parts hereinafter more particularly specifi-ed.-

Figure 1 is a side elevation showing our improved hay-carrier in position on its supporting rod and locked to the stop-block. Fig. 2 is a longitudinal section of the haycarrier. Fig. 3 is a perspective detail of the reversible head to which the bale-rope is attached. Fig. 4 is a perspective detail of the body-plate, having pivoted to it the bell-crank bracket, which forms the latch and carrierwheels7 journals. Fig. 5 is a perspective detail of the trip-bar and bailsupporting hook.

Fig. 6 is an enlarged sectional detail of thestop-block. Fig. 7 is a detail of the bail. Fig. 8 is a detail of the bell-mouth bracket.

Arepresents a portion of the supporting rod, which is supported in the barn in the y ordinary way.

B are the carrier-wheels provided with axles O, forming part of or connected to the arms D,

which forIn part of or are connected to the crank-brackets Ey the other arm of which forms the latch E, the said brackets E being pivoted at a on the body-plate G, as shown,

so that -a vertical center line drawn through 4c either of the axles C would pass outside of the center of its pivot c. Consequently the Weight of the carriage which is supported by these axles has a tendency to hold the outer end of the latch F upwardly, causing the latch F to snap under the stop-block Q and be heldin rigid connection' by the Weight of the load without the necessity of any spring. The

bottom of the body-plate G has a flange, b,

formed round a hole made in its center, anda corresponding flange is made on the top side of the head H, the said flanges being made strong to support the weight of the load, which is carried, as hereinafter described, by the said head H. This head H is made substantially as shown in the drawings, a projection, d, being made on one side of it to support the eye I of the bale or draft rope J. An extension, c, is formed on the side of the head H opposite to the projection d, in which eXtension the sheave-pulley K is journaled, as indi` cated. By thus carrying theload entirely by the'head H, which is pivoted, as shown, on the bottom of the body-plate G, the said head may be swiveled around Without interfering with the latches F, which, as before described, are pivoted upon the body-plate G.

XV e pivot the bail-supporting hook L cu a hub, N, formed on the trip-bar M, and provide a spring, O, designed to hold the hooked end of Ltoward the side of the bell-mouthf, which is made off the .center of the head H. The spring O also holds one end of the trips-bar M outside of that end of the body-plate G where it is desired to effect the trip. A tail, p, formed on the back of the hook L, projects between guides q, formed on the inside of the head H, so that the hook L must revolve with the said head. Then the bail P enters the bellxnouth f of the head H, it is guided by the said bell-mouth shape toward the bail-supporting hook L, which springs back to permit it to pass, and is then thrown into the bail by the action of the spring O. XlVhen the end of the trip-bar M strikes the stopblock Q, the supporting-hook J, which is attached to the trip-bar M, is pushed out of the bail, allowing the bail to fallout clear of the support specified. Owing to the fact that the bellmouth is on one side of the hole around which the head H is pivoted, and that the supporting-hook L is held against that side by the spring O, the trip-bar M is moved longitu dinally when the head H is turned on its pivot, as the said trip-rod M is connected to the supportinghook L. Consequently every time that the head is turned round its pivot the trip-bar M is adjusted, so that the trip-bar M will operate from the end opposite to that to which it has been previously set.

In addition to the arms D and F, each crankbraeket E has attached to or formed upon it an arm, It, which extends back and is bent so as to project through the hole in the bodyplate G, the end of the said arm R being in such a position that when the bail P passes the hook L the said bail must come in contact with the end of the arm It, and as this arm R is attached to Aor forms part of the bracket E the said bracket is rocked on its pivot a, so as to carry the latch F clear of the stop-block Q, thus releasing the carriage and permitting it to be drawn back on the rod A.

In order to permit the arms It t0 enter the hole in the head H, we make slotsg in the trip-bar, and, with the view of preventing the arms R gripping or binding the trip-bar M, We form on each arm R a lug, h, which butts against the top of the body-plate G and holds the arms R clear of the trip-bar M. On each end of the trip-bar M we form a heavy flange, i, through which the end of the trip-bar passes. These ilanges also serve the purpose of a butting-bloek to receive the shock When the end of the body-plate G strikes the end collar-beam used in supporting the ends of the rod A.

In Fig. 6 we show adetail of the stop-block, which is the same as that described in United States Patent No. 322,968, except that it has the following` improvement: IVe cast or otherwise attach onto the end of the lever j a projection, le, which, if the lever is jerked, will strike against the latch@l and knock it clear of the end of the lever j, permitting the latter to drop down free. By this arrangement the eXtra rope necessary to unlatch the stop-block described in Patent No. 322,968 is dispensed with. Ve mayfalso mention the fact that the latch F would be operated by the Weight of the carriage even if the pivotpoint a were directly upon the center line drawn through the axle C.

On reference to Figs. 3 and 8 it will be noticed that the bell-mouth opening f in the head H is an are of a circle, which at the point Where the supporting-hook L projects is made in size and shape to correspond with the bail I?, the top of which, as shown in Fig. 7, corresponds with the circle of the mouth f, while the side bars of the bail lit against the cord of the arc. Consequently when the bail enters the mouth its head or top bar, m, is guided directly over the hook L, the inside of the bar m being concaved, corresponding subst-antially to the outside circle of the said bar, so that when the bail enters the head no part of the bail can come in contactwith thespring O or head ofthe bolt securing the hook L.
