Improvements in a Manure Forkor Carrier,

of'which the following is a specification.

This invention relates t? that type of'i'm plements used for collecting or scoopingup and conveying material from one point to another, and while it is more especially in? tended" to be employed for handling barnyard manure and in connection. or co6perationwith an improved loading apparatus, such as is disclosed in an application, Serial. No. 325,065, for Letters Patent filed by me on the.7th day of July, 1906, yet it is applicable for use without such an apparatus or with a loading apparatus of different construction and. for handling and? removing other material, such as earth, ore, f'ertilizers, and. the like, and it consists in certain peculiarities of the construction, novel; arrangement, and operation of the various arts thereof, as will be hereinafter more fully set forth and. specifically claimed.

In. my abovementioned application. for patent on loading apparatus I have shown and described in connection with and as.

forming a part ofthe apparatus a fork or-carrier of substantially the same construction. as that forming the subject-matter of" the. pres-- ent applicatioirbut have not therein claimed said fork or carrier 1"- se, or,,rather, except in conjunction with t e apparatus or asforming a part thereof.

The principal object of the invention is to. provide a fork or carrier which shall be simple and inexpensive in construction, strong, durable, and effective in operation, and so made that it may be drawn by horse or other power over the ground and up an inclined? chute when desired and manually guided in. its forward movement, but automatically guided down the chute.

Another important object is to so construct the fork or carrier that it will automatically dump its load when it reaches a certain point on the chute and in such a man.- ner as to prevent it becomingywedged? between the sides of the chute by means of straw and fibrous manure.

Still another and important object is to provide means for preventing the tendency of the handles of the fork or carrier torise in its forward movement, thereby relieving the operator of great strain.

Other objects and advantages of the invention will be disclosed in the subj oi'ned description. and explanation.v

to which my invention pertains to make and use the same, I will now proceed to describe it, referring to. the accompanying drawings,

Fig. 14' is a. sectional view taken on line 14' 14: of Fig. 15" of one of the sides. of the fork or carrier, showing another form of its construction; and Fig. 153'is a perspective view thereof.

Corresponding numerals of reference indicate like parts throughout the different views of'the drawings.

The carrier or'fork may be of any suitable formsuch as a fork, scoop, or scraperfor gathering and holding the-.manure or material; but for the purpose of handling barn- In. orderto enable others skilled in the art.

.yard manure, which contains straw, hay, and

bers is provided on its inner surface with a rearwardly-extending'socket or channel 21,

' in each of which is located a handle 22, which project rearwardly and upwardly and are.

for the use of the operator in guiding the fork or carrier when the same is being filled.

On a front and downwardly-projecting extension 23 of each of the members 20 is horizontally secured a cross-head 24, which is preferably rectangular in cross-section and hollow andalso preferably has its ends fitted in sockets 25, formed in the extensions 23. The preferred construction of the cross-head 24 is illustrated in detail in Figs. 10 and 11 of the drawings and consists of a piece of channel-iron 26, having in its rear portion a number of circular openings 27 and between the front edges of its top and bottom a plate 28, which may have shoulders 29 to receive said edges. This plate has a series of rectangular openings 30 arranged in a horizontal row and so as toregister withtlie openings 27, which are for the reception. of the rounded and screw-threaded portions 31 of the tines 32, while the openings 30 are for the reception of the rectangular portions 33 of the tines and which keep them from turning in their sockets, nuts 34 being'used on the rear ends of the portions "31 to hold the tines in place.

Instead of using a cross -head of the above-described construction I may employ one of the form or make shown in Figs) 12 and 13, which consist of. a hollow bar 26 about square.in cross section, having in its front and rear portionslho'les 27 for the reception ofthe portions 31 of the tines. Located on'the front portion of the bar 26 is-a plate 28 which is provided with rectangular openings 30yto receive'the similarly-shaped portionsv 33 of. the tines. The cross-head, whether made as above described or otherwise, may have journaled on its rear portion at about its middle a wheel or roller 35, employed for assisting the movement of the carrier in its descent on the chute. This wheel has no particular advantage in moving the load upward on the chute, as the draftis such as to often lift it out of contact therewith; but when the carrier has discharged its load and is returned, so as to travel down the chute, the wheel which isplaced at the middle of the cross-head will strike the platform or chute and will act in the downwardmovement of the carrier as a leader therefor, permitting thetines to drag on the chute, thus guiding the carrier in a direct movement downwardly, whereas, if two wheels were employed on the carrier, if one of them came in contact with an obstruction it is obvious that the carrier would be deflected to one side and its further downward progress prevented by the side pieceof the chute.

Each of the members 20 is provided in its upper portion and somewhat re'arwardly from the cross-head 24 with a horizontal slot 36, in which is loosely locateda horizontallyextending hollow rod or cross-bar 37 the ends of which project a considerable distance from the outer surface of the members 20 and form pivots for the fork or carrier to coact with stops orlevers 38 on the upper part of an inclined chute 39 in order to cause the fork or carrier to be tilted, so as to dis charge its load. In Fig. 2 of the drawings I have shown a portion of the upper end of a chute 39, which is equipped with a supporting-bracket 40 to rest on the side of a wagon box or body or other receptacle to be loaded. The floor 41 of the chute terminates some distance from the upper ends of the sides 42 of the chute, thus providing an opening through which the carrier may operate and dump its load. The upper ends of the sides 42 are united by a cross-piece 43, on which is 5 j ournaled a pulley 44, over which a cable 45, attached at one of its ends to the bail of the fork or carrier and used for drawing the same, passes. On each side of the chute and usually pivotally secured to the bracket at its lower end is a lever or stop 38, which proj ects above the upper edge of the sides 42, so as to be in the path of the prbjecting ends of the rod or cross-bar 37 or pivots: As there is considerable strain on these pivots or proj ecting ends, I prefer to use a hollow bar or rod 37 and reinforce its ends by placing therein solid rods orbars 46, (see Figs 5,) which may be secured in lace by means of pins 47, passed through col ars 48, one on the outer side of each of the members 20, and through the rods 46 and rod or bar 37, thus preventing longitudinal movement of the last- .named rod. At the rear end, somewhat above the rod or bar/'37, the members 20 are transversely connected by means of a crossbaror rod 49, preferably hollow and reinforced by solid rods 50 in each of its ends.

Secured on the cross-bar or rod 49 and usually by means of clips 51 are the rear ends. of a bail 52, the front end of which has the cable 45 connected thereto. As shown in Figshl and 9, each of the clips 51 is provided with a lateral projection 53, located slightly to the rear ofthe rod or cross-bar 37 or the pivots of the carrier. However, these jections may be made integral with the arms of the bail, as is evident.

Fulcrumed at its lower end on each of the members 20 is a lever 54, each of which has in pro- ' cations oftlie implement, and in Fig. 4

its upper front portion: a recess to engage the projections 53 on the arms of thebail. The upper end' of each of" the levers 54. is rounded or beveled, and the lower Wall' of: each of'therecesses therein is-longer than the upper wall for the purpose of more effectual engagement with said projections. Each of said? leversis provided on its rear surface, at about its middle, with alug 56-, around which is fitted one end of a coil-spring 57, the other end of which i'sfi'tted around a lug 5'8-OI11tl'16- inner surface of each of the side members. These springs serve topressthe levers54;for wardly, sothat the recesses 55 willienga-ge-the projections 53", and thus firmly hold the bail 52 in itshorizontalor loweredposition-until the ends ofthe rod or cross-bar 37' or pivotsof'the carrier-strike the l'evers 38 or stopson the chute, by-meansof which the rod orbar 37'will'be pressed backwardl y the-slots 36', thus disengaging ections 53' and, permitting the carrier to be dumped. Each of? the members 20: is pro.-

vided on its outer surface with one or more I what I claim as new, and desireton secure by pairs of spaced apart and? horizontal lugs 59 to; receive the rear ends of auxiliary tines 60, used for preventing the materialfa-lling off the sides of'thecarrier. Instead of using the horizontally disposedlugs or-ribs 59 for theabove-named purpose, as shown in Figs. 1, 2, 5 to 7, inclusive, I may employ apertured lugs 61, as shown in- Fig. 1 5 of the drawings, in which figure, as welli as in Fig. 14, it will be observed that each of the members20 isprovided with a pivot 37*, which is integral therewith and which form I may sometimes employ.

In Figs. 6 and; 7 of the drawings I have shown another modification in the construe tion of the side members 20, which consists inusing a hollow cross-bar orrod 37- without the reinforcingrods and in fastening it by means of. pins 62- to said members.

As shown in Fig. 1' of the drawings, the cross-head is connected-to the handles by means of diagonally and upwardly-disposed braces 62*, which serve to strengthen the device andto-some extent prevent theload escaping through the rear part thereof. As one of the important features of my present invention is to provide a fork or carrier of such construction as to enable-it to be easily dumped? at theproper time, and as I do not desire to, be limited. tothe specifi'cconstruction of the device except where so claimed, and as the facility of the dumping operation depends largely on" the novel and peculiara-rrangement of theparts of the device with respect to one another, and particularly on the arrangement andlocation of the bail and pivots, I have shown several modifihave shown a perspective view illustrating the broad idea of the construction to facilitate the tilting or dumping thereof which consists thelevers 38 from the pro-'- in employing an upright board or plate24l, to the loweredge-of which is:secured a series of forwardly projecting' tines, the outer' or side ones of which are-braced, t0 the ends of the; board 24. and, handles: 22; by; meansv of bars 20 to= which the endsv of the; bail: 52. are

secured at points above and: slightly to; the rearof a cross-bar'3'7fiwhichis longitudinally secured on the board 24- and: has itsends proj ectecl' beyond. the same.

From the foregoingand by referencev to the drawings-it Will lee-understood and ole arly seen that when the carrier is drawn. upwardly on the chute and reaches the upper portion thereof the projecting arms: or pivots. will, strikeprojections, steps, or levers with which the chute is provided, and! thus. through. the draft, through the bail which. is: connected. to thefork or carrierabovethepivots or dumping arms thereon. which; armsor-pivots are located onthe-sides and nearthe rear-0f the-device, willl cause the fork orcarrier to; be'roe' tated on the pivots and? dumped of its-load.
