lar sprocket wheel 26 is secured onthe end of the transmision shaft 22, a sprocket chain 27 being trained around these sprockets. A spiral gear 28 is secured to the transmission B shaft at a point near the rear wheels 4and meshes wit the spiral gear 29 on a transverse drive shaft 30 journaled in bearings 31 depended from the lower frame rails 2. Large 32 are secured within, or to 4one l side of, the wheels 4 and pinions 33 on the ends of the shaft mesh therewith. Thus it will be apparent that the machine may be driven over the ground by theengine 11 and it will be understood that any conventional 16 form of speed shifting and control means may be used upon the engine, and no specific form being here shown.

A transverse shaft 34 is journalcd in hearings 35 upon the top rails 3 extending out- 20 wardly at one end and a large gear 36 is secured thereon in mesh with the pinion 17 on the drive shaft 12. Short stuh shafts 37 are journaled in side plates 38 and large drive gears 39 are mounted upon the inwardly ll turned extended ends thereof. linions 40 upon the shaft 34 mesh with the gears 39 so that the latter will be rotated by the motor 1 l as will be understood.

A plunger or beater 41 is reciprocatingly I0 mounted inthe frame 1, the same comprising the head 42, sides 43 and slotted bottom 44. This plunger 41 has transverse rollers 45 journaled in the said slots in t-he bottom 44 which will roll along the horizontal webs of 85 the angle irons forming the lower frame rails 2. A connecting rod 46 is pivotally mounted in the beater 41 on a pin 47 and is also pivoty ally mounted at its oppositel end between the gears 39 on aA pin 48 supported eccentrically 40 upon the said gears. the ends of the said connecting rod being laterally enlarged as shown for this purpose. It will now he understood that as the gears 39 are rotated b v the means hereinbefore set forth, the plunger 41 will be caused to reciprocate within the frame 1 and so will press or bale hay forced therein byV a means to be set forth.

Y The separating block holderor slide 49 of the shape clearly shown in Figure 16 has a 60 slideway formed between the ends 50, the back 51 and the webs 52. This block holder 49 is pivotally mounted between the top frame rails 3 by short pivot pins 53 passed through the apertures 54. A gear 55 is secured upon S5 one of the pivot pins 53 and a gear 56 with a handle 57 on a pivot pin 58 meshes therewith and by raising or lowering the handle 57 the block holder 49 maybe raised into the vertical or operative position shown or lowered so that 60 it will lie iiat upon the frame 1. A block operating mechanism is provided comprising the arm 59, the forwardly disposed end of which is bifnrcated and the arms pivoted in brackets 60 upon the top frame rails 3. A

I5 link 61 is pivotally connected by'one end at .62 to a medial point of the arm 59 and is similarly connected at its opposite end to an ear or lug 63 formed upon the upper side of the connecting rod 46. A rectangular block hammer or striker 64 is secured upon the free end of the arm 59. A separating block 65 is provided to separate the bales one from another as they are formed by the means hereinbefore set forth, and the same is of the usual form havinglgrooves 66 through which the wires (not shown) may be assed when wiring or tying the bales. In t e use of the bale separatln g elements the block holder or slide 49 is raised to the vertical position when enough hay has been pressed to form one bale and a separating block such as described isinserted therein. The arm 59 due to its connection with the connecting rod 46 is caused to move .vertically up and down and thus the block striker 64 will impinge the upper edge of the 85 block 65 forcing the same downward into the baling chamber and separating the hay therein as will be understood.` When the block holder 49 is not in use it is adapted to lie flat upon the frame and in this position the striker 64 will clear the same having no effect thereon. It will be understood that a block may be inserted in the holder and forced downward by hand to form an end piece or brace against which the first'bale may he pressed. 95 The bales are tied in the usual manner, suitable platforms 67 being secured on brackets 68 at the sides of the frame u on which the tiers may stand. The rear en( of the frame may be constricted, when necessary to hold 10 the bales within the frame, or to cause the same to be pressed more tightly, by means of the handwheels 71 which threadedly engage the ends of the bolts 72. These bolts 2 are secured at their lower ends to a cross- 105 piece 73 and small lugs 74 are loosely placed upon the upper ends as shown bearing upon the upper frame rails 3. By this means the spaced lower frame rails 2 and the upper frame rails 3 may be drawn together. it beingr understood that the side plates are omitted adjacent the rear of the frame.

A rectangular table 75 is loosely mounted upon the lower rail 2 at a medial point of the frame and the free margin thereof is provided H5 with a supporting frame comprising the depending vertical' members 76 and the horizontal member 77. A side brace member 7 8 is mounted by one yend upon the axle 5 and lextends forwardly and outwardly and is se- 12 cured to the lower ends of the vertical frame members 76. An adjusting rod 7 9 has its upper end 80 threaded and passed loosely through sockets 81 formed in hoth the horizontal member 77 and the brace 78. A bev 125 eled pinion 82 threadedly engages theI threaded end 80 of the adjusting ro'd7 9. A small castor wheel 83 has its. axle journaled in a bearing 84 on the foot 85 formed at the lower end of the rod 79. '13

i claimed in respect of same as here applied.

As shown in Figure 3 a bearing hanger 88 is depended from the inner margin of the table adjacent the front thereof and a bearing aperture 89 is formed in the brace 78 in alignment therewith. A rake shaft 90 is journaled through the bearing hanger 88 and the aperture 89 and is provided at its inner end with an internally toothed bevel gear 91. A bearing arm 92 is secured on, or formed integrally with, the bearing hanger 88 and a bearing bracket or ranger 93 is depended from the bottom plate 69 of the frame 1. A shaft 94 with a universal joint 95 is journaled in the said arm 92 and hanger 93 and has a beveled gear 96 on one end meshing with the gear 91 on the rake shaft 90, the said shaft also having a beveled pinion 97 at its opposite end. Bearings 98 are provided on the sides of both the upper and lower frame Arails 3 and 2 and a shaft 99 is journaled vertically therethrough, the same having at its lower `end the large bevel gear 100 with which the beveled pinion 97 meshes. A beveled pinion 101 on the end of the sleeve 24 meshes with the said gear 100 and motion is transmitted to lthe sleeve 24 from the jack shaft 20'by means of sprocket 102 and a sprocket chain 103 substantially as hereinbefore set forth for the transmission shaft 22. The large beveled gear 100 is thus rotated and the rake shaft 90 will be turned in the direction indicated hy the arrow by means of the shaft 94 and its associated gears.

A revolving rake 104 is secured upon the rake shaft 90, the same comprising the side frame wheels 105 and 106 secured upon the said rake shaft in spaced relation. Rods 107 are journaled through the rims 108 ofthe said wheels 105 and 106 and extend therethrough at their outer ends for a purpose to be described. Rake teeth 109 are secured upon the rods 107A at equally spaced intervals and it will be understood that the said teeth may be spring set in any ccnventional manner as by spring set rule joints (not shown) so as to prevent breakage when strikingobstructions in the field. Theforward margin of the table 75 is arcuately curved in a downward direction and is provided with slots 110 through which the rake teeth 109 are adapted to pass as they revolve. To allow the said rake teeth 109 to clear the table 75 a cam 111 of the shape shown in Figures 1 and 7 is secured by bolts 112 to the vertical frame member 76. The said outer extended ends of the rods 107 are provided with an gularly bent arms 113 upon the ends of which are rotatably mounted the rollers 114 adapted to bear against the face of the cam'111. In this manner when the rake teeth 109 are in the lower portion of their -travel they are held rigidly extended but as they enter the slots 110 in the table 75 the. rollers 114 disengage the cam 111 and the teeth and rods 107 turn freely so that theA said teeth will clear the table,

The hay thus deposited on the table 75 is fed into the hailing chamber by a fork 115 adapted to enter the feed opening 116 in the side plate 70. A slide rail 117 is mounted on the table 75 at the rear margin thereof by standards 118 and the said rail 117 is T- shaped in cross section as shown. A slide block 119 is slidably mounted on the rail 117 and has at its rearwardly disposed side a vertical bore or bearing aperture 120. The fork 115 comprises a crank 121 as shown in Figure 8, the said crank being formed'of a hub or. shaft 122 rotatably seated through the bearing aperture 120 and the upper and lower arms 123 and 124 secured at one end to hub 122 and held in spaced relationship above and below the slide block 119. A vertical shaft is secured to the free end of the upper arm 123 and a short stub shaft 126 is secured to the lower arm 124. The fork ti nes -127 are secured at a medial point to the shafts 125 and 126 adjacent the upper and lower arms 123 and 124 and have the bifurcatd hay engaging ends 128. The shaft 99 is extended above the top of the frame 1 and provided with a rigidly fastened crank arm 129 at its upper end, the said crank arm having at its outer end the short stub pivot shaft 130. A sprocket 131 is secured upon the upper end of the shaft 125 on the crank arm 123 and a similar sprocket 132 is secured upon the stub pivot shaft 130, a sprocket chain 133 being trained around these sprockets as shown. A connecting link 134 is rotatably mounted by iltsoends on the said shaft 125 and pivot shaft It will now be-understood that the rotation of the shaft 99 through the pinion 101 and gear 100 as hereinbefore set forth will cause the crank arm 129 to rotate. This arm through the link 134 will cause the crank 121 throw than the arms 123 ofthe crank 121. Bv 4 means of the sprockets 131 and 132 and the sprocket chain 133 the crank 121 is caused to rotate completely around on its hub 122 and this sprocket and chain connection is so adjusted that when the fork is on the in stroke, that is, feeding hay inward from the tablel'751into the baling chamber, the bifurcated ends 128 of the tines 127 will swing or sweep forwardly and inwardly to the frame over the said table. 'Ihe said tines are ada ted to swing somewhat within the baling chamber on their in stroke as shown in I" re 4 and it will be understood thatthe folil 115 and plunger 42 must be arranged or timed so that when the said fork is sweeping inwardly `to the baling chamber, the hunger 42 must be drawing `forward inthe e 1 on its inoperative stroke and this relationship'is also clearly shownin Figure 4. On the ont or inoperative stroke of the fork the said bifurcated ends 128 of the tines 127 will swing to the jrear behind the table thus clearing the hay accumulated on the table'as the fork as in the baling chamber. Thus the fork makes a complete revolution during the in and out strokes and at the Sametime the entire vassembl is slid inwardly and outwardly on the T rail 117. In Figures 1, 2 and 3 the fork is shown just starting its in or feed stroke and in Figure 4 the same is shown as its feed stroke is completed and as it starts swinging outward on its out stroke. This construction provides a very etlic'ient meansl for forcing hay into the baling chamber as will be readily appreciated.

In order to retain the hay in the baling chamber as it is being baled, I provide a doorl denoted generally at 135 adapted to close the feed opening 116 and it is obvious that this door must operate in connection with the fork 115, that is, when the fork is feeding hay into the baling chamber the said door must be open and as the fork is drawing outward on its inoperative stroke the said door must close. Guideways 136 are secured to the upper and lower frame rails extending along above and below the feed opening 116 and to the rear thereof as shown, the said guideways being disposed with their troughs reversed or facing each other as will be understood. The door 135 is provided at each end with rollers 137 rotatably mounted in brackets 138 and these rollers are adapted to roll in the guideways 136 in such manner that the door 135 may be readily moved to and fro to open or Iclose the feed opening 116. A large medial slot 139 is provided in the door 135 to clear the T rail 117 and spaced from either side thereof are narrow slots 140 to clear the fork tainthe same in the forward or closed position. A lug or catch 142 is secured to the upper forward margin of the door 135 and projects inwardly into the baling chamber, a slot 143 being provided in the frame side late to allow for the movement backwardy and forwardlyvthereof. It will be understoodv that yas the plunger 41 moves into the baling chamber on its pressure stroke, the head 42 thereof will strike the lug 142 forcin the door 135 open. In order to retain the sai door in the open position as the plunger is moving out of the baling chamber and while hayis being forced'throughthe opening 116 I provide a catch lever 144 pivoted at 145 to the upper frame rail 3 and being of sucient length to en age the forward margin of the door when e same is open. An elongated operatin rod 146 is loosely attached at 147 to a me ial point of the catch lever 144 and extends forwardly through a bracket 148 secured to the said upper frame rail 3 and terminates in a trigger 149. 'A coil spri 150 is stretched between the trigger 149 an the bracket 148 serving to normally swing the catch lever 144 rearwardly against the door 135, astop 151 limiting this motion. As the plunger 41 reaches the end of its inoperative stroke drawin out ofthe baling chamber the side 43 thereo will strike the trigger 149 pullin the rod 146 and catch lever 144 forward re easin the door `135 the coil spring 141 then u ling the said oor forward into its close osition, it bein understood that the timin etween the for and lunger is such that t e hay is fed into the aling chamber while the plunger is withdrawn therefrom. In order to allow the door 135 to pass the catch lever 144, as it opens the latter is provided with a spring set rule joint 152. A slot 153 in the side 43 of the plunger allows the same to complete its inoperative stroke before it actuates the trigger 149 to close the feed opening door as will be understood.

Dogs 154 are pivoted at 155 in slots 156 in the side plates 70 on either side of the frame to the rear of the feed opening 116, their purpose being to retain the hay in its pressed condition as the plunger recedes to press another portion of hay. These dogs 154 are sprin set to normally swing into the baling c am r a sutlicient distance so that the hooks 157 thereof will engage the hay. The plunger 41 when pressing the hay strikes the arcuate outer faces 158 of the said dogs 154 forcing them outward so that the said plun er may pass as shown in the dotted lines in B igure 10.

An elevator denoted enerally at 159 is provided upon the reareo the frame 1 to deliver the bales clear of the machine. A table 160 is secured by bolts 161 to the lower frame rails 2 and the vsaine is provided with spaced upstanding lugs 162. An elevator frame 163, U-shaped in cross section, and having aligned bearing apertures'164 at either end of its side portions is mounted between the lugs 162 and extends laterall and angularly upward from the frame as s own in Fi re 6. Toothed elevator rollers 165 are rigidly mounted on shafts 166 journaled in the bearing a rtures 164, the lower shaft being exten ed outwardly through the lugs 162 serving as a pivot for the frame 163 as shown at 167 and provided at Aits forward end with a sprocket 168. A simi lar sprocket 169 is provided on the rear end of the transmission shaf t 22 and a sprocket chain 170 is trained around these sprockets so that rotary motion will be transmitted to the lower elevator roller 165 as will be understood. An elevator belt 171 of suitable material such as canvas is stretched over the rollers 165, the inner surface of the belt being provided with equally spaced transverse slats 172 to engage the teeth upon the wheels. Small spikes 173 are provided on the belt in order to obtain a firm grip upon the bales when elevating the same. An adjusting rod 174 is loosely secured to the upper end of the elevator frame 163 and has its opposite end threaded and loosely passed through a standard 175 upon the frame 1. A sprocket 176 threadedly engages the threaded end of the rod 174v and it will be understood that by turning the said sprocket 176 the rod 17 4 may be moved outwardly or drawn inwardly, this action varying the angle of the elevator 159 as will be understood. A hand wheel 177 with sprocket 178 is provided and by training a sprocket chain `179 over the sprockets 176 and 178 the angle of the elevatormay be varied at will by the machine operator.

The tiers when a bale is tied may pull the same ont the open rear end of the frame onto the table 160. The bale may then be placed upon the elevator 159 and delivered to a wagon or truck driven beside the baler. The operator by means of the handwheel 177 may vary the height of the outer end of the elevator at will to deliver the bales to the wagon in any position.

From the foregoing it is obvious that I provide a machine which is positive and eilicient in operation and which completely eliminates thi` raking up and loading of hay in the field and then transporting the same to the baling machine.
