H AY L O A D E R SPECIFICATION forming part of Letters Patent No. 488,561, dated December 27, 1892.

Application led December 3l, 1891'. Serial No, 416,669. (No model.)

To all whom it may concern,.-

Be it known that I, CHARLES A. HENRY, a citizen of the United States, residing at Monticello, in the count-y of Jones and State of Iowa, have invented a new' and useful Hay-Loader, of which the following is a specification.

This invention relates to hay loaders of that class known as walking rakes; and the object of the same is to produce certain improve-V ments in machines of this character.

To this end the invention consists in a hay rake and loader constructed substantially as hereinafter more fully described and claimed, and as illustrated on the accompanying three sheets of drawings, wherein- Figure lis a plan view of this machine with the extension frame drawn out to its fullest extent. Fig. 2 is an elevation of the right side of the machine with the extension frame at its innermost position. Fig. 3 is a rear ele- Vation of the lower part of the machine. Fig. 4 is a longitudinal section showing the adjusting bar raised and the extension frame partly drawn out. Fig. 5 is a detail perspective view of the mechanism for connecting the feed-bars. Fig. 6 is a detail perspective view of one of the catches showing the pin as just slipping off the same. Fig. 7 is an elevation of one of the rake controlling mechanisms showing how the pin is positively prevented from returning above the said mechanism.

This machine comprises the following instrumentalities, each of which is preferably of the specific construction hereinafter set forth at length: A wheeled framework W supports an inclined trough T having an exten sion frame E at its upper end.

F are feed-bars arranged in two sets and having rakes R at their lower extremities, and said extremities are given peculiar movements by triangular switches and tracks C which are supported by an automatic adjusting bar A; one set being driven by the driving mechanism D, and the other set being driven by the mechanism M which connects it with the iirst set.

I have shown in the drawings and described herein what I consider the preferable construction of this machine, but I desire it understood that many changes in the details can be made without departing from the spirit of my invention, while obviously certain parts thereof could be used without others; and the elaboration, specific construction, materials, and sizes of parts will be left to the manufacturer and form no Vpart of the invention proper.

The lwheeled framework W1, l are main wheels mounted loosely on an axle 2, and the latter is journaled in 'boxes 3 under a framework composed of such sills, bars, and braces as may be necessary but whose exact construction is immateriaL-and 4 is a tongue (or in some cases it may be a pair of thills) projecting forward from this framework and to which the team is to be connected fordrawing the machine over the ground, or which is to be attached to the rear of a hay-rack when the machine is in operation.

The trough T.-Supported by the framework l/V in any suitable manner is an inclined trough T preferably comprising transverse beams .l0 on which are mounted longitudinal strips 11, the strips terminating short of the upper end of the trough while the sides l2 of said trough extend completely to the upper end thereof. The lower end of this trough travels near the ground while the upper end is high enough to deliver on the top of the highest ordinary load. Strips 12 are secured to the transverse beams 10 of the sides 12 and form a means of support and securement for parts of the frame. y

T he etension frame E To depending bars 2O on the sides of the trough are secured longitudinal guides 2l on which move bars 22, and to the bars are connected the ends of transverse sills 23 forming the bed of the frame E. From the upper ends of said bars 22 project bars 22 connected at their outer ends by a sill 23'; while 24 are `longitudinal strips on the sills 23 and 24E similar strips on the sill 23-all these strips forming the bottom of the extension frame as will be understood. Depending from the bars 22 are hooks 25 adapted to engage pins 26 projecting inward from the guides 2l to support the extension frame at the desired height. In Fig. 2 this frame is at its lowest point, in Fig. 4 it is partly drawn out, and in Fig. l it is completely extended. When iirst beginning to IOO load this frame will be in the first of these positions because it is not necessary to raise the hay so high, and this saves raising the weight for one-third of the distance. As the load increases in height the frame is extended as is necessary. t

The feed-hars F and rahes R.-As above stated, the feed-bars are arranged in two sets, there being here shown three in one set and two inthe other between those of the first. At its lower end each bar carries a rake R of any suitable construction but preferably composed of a cross-head 30 whereon are coiled springs 3l having depending teeth 32 Within the body of each bar throughout its length is inserted a number of teeth, each consisting of a piece of strong spring-wire 33 of inverted U shape whose ends are passed down through the bar and curved forward, and whose body where it rests on the bar is secured thereto by a staple 34. Mounted on the alternate bars are boxes 35 and 36 for a purpose to appear hereinafter; and mounted on each'bar near its lower end is a block 37, while secured at its center under the bar opposite the lower end of this block is a U- shaped tinger 38 one of whose arms has near its extremity an inwardly-projecting pin 39.

The connecting mechanism ll.-At each side of the trough 'l in its upper end is a pair p of uprights which are formed by extending the bars 2O upward and from whose inner faces project stub-shafts 4l whereon are jou rnaled sprocket-wheels 42, the wheels being connected by an endless belt 45. 44 is a transverse bar mounted inthe boxes 35, eX- tending across the entire machine, and connected as at 45 to the upper sides of the two belts as shown. 44 is a second transverse 'shaft standing across the trough at about the center of the latters length and mounted in the boxes 36; while 47 are rods leading from the ends of this shaft, down, thence forward, and thence outward where they are secured as at 47 to the lower sides of the two belts. 48 are pins projecting outward from these rods, passing over the chains at the under sides of the belts, and travel on the upper edges of the sides l2. It will thus be seen that when the outer bars move down their conntcing rod 44 moves the points 45 of the belts down, and this causes the points 47 to move up, whereby the bar 44 moves up and gives the inner bars F a similar motion which is opposite to that of the outer bars.

T he driving mechanism 1).-Secu red to the hub of each main wheel l isa ratchet-Wheel 50, and journaled on the shaft 2 adjacent this ratchet-wheel is a sprocket 5l carrying a spring-actuated pawl 52 engaging the teeth of the ratchet whereby the sprocket is turned as the machine moves forward. 53 is a main driving-shaft journaled in boxes 54 supported by uprights 55 from the trough, and on this shaft are secured sprockets 56 which are connected by chains 57 with the sprockets 5l on the main shaft or axle. On the outer ends of the main driving-shaft are cranks 58 which are connected by pitman-rods 58 with the transverse bar 44 above mentioned. Thus when the machine progresses and the main driving-shaft revolves, the cranks cause the bar 44 to be reciprocated longitudinally of the trough, and this gives the feed-bars F the necessary movements.

The automatic adjusting bar 4.-60 are upright guide-brackets secured to the rear faces of the uprights 55, the brackets and the uprights being provided with a series of registering holes. 61 and 62 are pins connected in pairs by chains 63, and one of these pins can be inserted in certain of the holes to limit the upward movement while the other pin likewise limits the downward movement of a transverse bar 65 which extends entirely across the machine, passes loosely through the brackets 60, and has blocks 66 which travel against the inner faces of the uprights 55 to prevent its vlongitudinal displacement.

The rake controlling mechanism 0.-Secured to blocks 70 on the rear face of the bar 65 are a number of angular metallic tracks 7l whose rear ends are connected by a transverse bar 72. Rising from each track just in rear of its angle is an ear 73 to which is pivoted a triangular frame 74, the upper side of the latter standing about horizontal and having lips 75 and 75 at its front and rear ends. 76 is a cup carried by the ear, and 77 is a coiled expansible spring seated at its lower end in the cup and its upper end bearing under the upper side of the frame 74 and throwing the front lip 75 down against the inclined portion of the track 7l. The arms of the U- shaped linger 38 are spaced just sufficiently' to permit them to travel astride these tracks 71,l and the ear 73 is at one side of each track so that the pin 39 in each of said ngers can travel uninterruptedly along the other side of the track and around the triangular frame. With this construction, as the feed-bars F rise their pins 39 slide along the horizontal and then up the inclined portions of the tracks, passing under the lips 75 as seen in Fig. 4, and on the return-movement of the bars F these pins pass out over the flat upper sides of the `frames 74 as seen in Fig. 2. When each pin reaches the rear lip 75', the block 37 striking under the corner of the track draws down on the finger so that its pin causes the frame 74 to tilt as seen in Fig. 6, and the pin slips off and falls onto the rear end of the track 7l forward of the bar 72. At this time the rake R is in its rearmost position and about to move forward, but supposing it falls on a large y pile of hay as the pin slips off the frame-the block described prevents the pin returning over the top of the frame, because it passes under the rear lip 75 and thence down under the inclined rear side of the frame as will be understood. Many inequalities in the ground and in the amount of hay being raked will thus be overcome, and even if vthe ground undulates considerably, the rake-teeth will not be embedded therein because the adjusting-barA can rise Within its guide-brackets so that all the catches and rakes can rise and fall as may be necessary.

When it is desired to drive this machine over the ground without operating the rakes or the feed-bars, the pawl 52 maybe held out of engagement with the ratchet 50 by moving said pawl to the rear, when 'the notch 59 in the spring 59 will engage the stud or pin 59 to hold the pawl out of engagement with the ratchet-all aswill be understood from an inspection of Fig. 2. v

With the above construction of parts, the operation of this improved machine is as follows: The tongue being hitched to the rear of the wagon carrying the hay-rack and such wagon being drawn over the field, the rotation of the main wheels l communicates power to one set of feed-bars F while the other set is driven through the connecting mechanism INI. The rakes R at the rear ends of the feedbars reach down and out and grasp the hay, drawing it onto the lower end of the trough through the movements of the pins 39 around the frames of the rake mechanism, and after the hay has passed into the trough the teeth 33 grasp it and carry it up therein.` The extension frame at its lowest point permits the hay to fall directly onto the hay-rack as will be understood, and as fast as the hay increases the height of the load, the extension frame is raised so as to cause the additional hay to be delivered on the top of the load. As above stated, inequalities in the sizes of the piles or bundles of hay grasped by the rakes will merely cause the latter torise, but their blocks 37 strike the horizontal portions of the tracks 7l before the pins 39 can pass over the rear lip and if the ground is undulating or the pile of hay larger than this motion can accommodate, the entire set of rakes and rake mechanism will rise as permitted by the loose mounting of the automatic adjusting bar in the guide-brackets. To limit the movement of the adjusting-bar therein the pins are set in the holes as required, and by this same means the rakes can be held entirely out of operative position when desired.
