Specification of Letters Patent.

Patented Dec. 10, 1907.

Application filed March 8:1906. Serial No. 304.934.

To all whom it may concern:

Be it known that I, JAMEs CALDER, of the city of Hamilton, in the county of Wentworth, Province of Ontario, Canada, have invented certain new and useful Improvements in Ap mates for Shocking Grain, of which the to lowing is a specification.

My present invention relates to improvements in apparatus for shocking grain of the typeshownj and described in my prior United StatesapplicationfNo. 209,816 dated 25th May, 1904, in which bound sheaves arereceived froma harvester binder by a shock receptaclenormally horizontal but capable of being swung to a vertical position to dum a shock and opened at its rear side to permit the receptacle to travel away from the dumped shock.

In my former construction I employed a curved swinging needle to cooperate with a knotter to bind the shock together. I found it vorydillicult with such a needle to secure proper registration. between it and the knotter owing to the dilliculty of securing sulficient rigidity in the needle, itssuppprts and operating parts. 1

In my present invention I secure perfect cooperation by using a straight needle reciprocating in suitable guides supportcdimmediately adjacent to the knotter.

In my former construction I received the sheaves from the-harvester binder on a sheaf receiving and carrying table which was at predetermined intervals moved to deposit one or more collected sheaves in the shock receptacle. This construction was not satisfactory in operation and. did not properly pack the sheaves into the shock receptacle.

In my present invention I make the sheaf.

receiving table stationary and employ a series of dischargers and packers working through it to discharge the sheaves at redetermined intervals and pack them in t e receptacle.

I have also devised improved mechanism for operating and coordinating the various parts subsequently, as hereinafter more 'spe cifically described and then definitely claimed.

Figure 1 is a perspective view of my improved apparatus, showing also a portion of the binder to which it is attached. Fig.2 is

a side elevation looking towards the binder deck of my improvements. Fig. 3 is a rear sectional elevation of the same showing a arms which impart-a reciprocating motion to Fig. 9 is a diagrammaticahview.

n the drawings like letters of reference -in-.

dicate cer esponding parts in the different figures. i.

Referring particularly to Fi 1, 1 is the shock rece tacle constructed su stantially as described in the prior application referred to, that is to say, it IS suitably shaped to receive the sheaves'as discharged from the sheaf receiving table 2 being open at the side immemodification of the binder-deck. Fig. 4 is a diately adjacent to the table for that purpose. The sheaf receptacle is also provided with the gates 3 hinged at 78 on the frame of the receptacle so as to open rearwardly."

The gates, after the shock has been dumped, are returned to their normal position by contact with the diagonal bars 4, which gradually push the gates inwardly to the position shown. Only one of these bars is shown clearly in Fig. 1, but it will be understood that a bar 4 is provided for each gate. In practice means Will be employedfor lockin and releasing the gates, but as this is old an forms no part of the present invention, the

description and illustration thereof is omitted. The sheaf receptacle, is pivotally connected to the upper ends of the links or bearing levers 5. Owing to the unequal lengths of these levers, as they are swung rearwardly,

they tend to draw the receptacle to a vertical position. Movement is imparted to the links y means of a pivoted pitman 6 connected with the forward links 5 and to cranks 7' formed on the shaft 8 suitably journaled on the frame of the a paratus.

The parts already described are old, my present invention lying particularly in the parts about to be described.

; On the frame of the apparatus in front of v the shock receptacle is supported a butt the shock receptacle.

proper.

board also serves to even up the base .of the shock before it is deposited on the ground.

From the above description, and. on reference particularly to Fig. 9 ofthe drawin s, it

v I will be seen that when the receptacle is moved. 10

to dump a shock it is first lifted bodily away from the butt-board and slightly elevated. The receptacle is then tilted to a vertical positionon its upper pivots and drops slightly towards the ground. This combination of movements enables the butt of the shock to clear itself from the butt-board before the receptacle is tilted, and also enables the shock receptacle and the butt of the shock to clear the ground during the tilting movement In Fig. 9 the aths of the pivots are shownfby arcs of circ es, the upper pivots first move to the rear end of the 11 per arc the movement away from t e buttgiving 7 oar and also a lift, but by the time the 25 lower pivots reach the ends of their paths the upper pivots have moved forwardly and downwardly part. way towards their original position.

The sheaf receiving table 2 which in my prior application was movable is now formed as' a fixed extension of the binder deck 10. It may either incline upwardly, as shown in Figs. 1 and 2, or the binder deck may be raised sufiiciently to enable the table to slope downwardl at the same angle as the binder deck, see Fig. 3. The binder deck being sta tionary, it is necessary to provide means for discharging the sheaves from it, and. I have been enabled to devise discharge means which. will also serve to pack sheaves within For this purpose I journal below the sheaf receiving table the discharge and packer arm shaft 11. This is provided with a plurality of cranks 1.2, on which are journaled the discharge and packer arms 13.. The tails of these packer arms are connected to suitable pivoted links 14, the other ends of which are journaled on what I may call my main drive shaft 15, since it is the main shaft of my special mechanism. Thus as the shaft 11 is rotated the upper ends of the discharge and packer arms 13 will move up in a curved path through the sheaf receiving table forwardly into the opening of the shock receptacle, thence retiring to their original position shown in Fig. 3. The method of imparting movement to this dis 'charge and packer arm shaft will be hereinafter described. To properly hold down the sheaves during thcoperation of the discharge and packer arms, l cxtend thc strippers 76 of the knotter of the harvester binder and connect their ends to the needle shaft 19 (see Fi 1).

To the end of the main drive shaft 15 is 50 season cured a crank arm 16' connected by a suitable pitman 17 with acrank arm 18 on the end of the needle shaft 19. (See Fig. 2.) To the needle shaft is secured a crank 20 pivoted to one end of a link 21, the other end of which is ivoted to the end of the needle 22, which is ocated adjacent to and in front of the knotter 83; of the binder.- This needle is preferablycstraight and is suitably supported so that it may be reciprocated in the guides 23 supported in any convenient part of the apparatus.

In the drawings I show the guides connected to a bar 80 supported from the end of the bearing of the knotter shaft 81 of the binder and on a sleeve 79 journaled on the shaft 19.

Owing to the roportioning of the various crank arms it will be seen that a rotation of the main drive shaft 15 would cause a reciprocating movement of the needle to cause it to coact with the knotter 24. As this knotteris of ordinary construction it is not illustrated in detail. Suffice it to say that it is operated by means of a sleeve. 25 journaled on the. discharge and packer arm shaft 11, the sleeve being 0 erated simultaneously with the operation 0 the main drive shaft 15, as hereinafter described.

In connection with the needle, I show a T-headed rod 77 which is pivoted at one end of the needle and is loosely uided in front of the same (see Fig. 5). As t he needle descends the T-head of this rod comes down in front of it to hold down the cord in front of the needle while the knot is being tied.

The proper operation of too apparatus requires that two or more sheaves be collected on the sheaf receiving table and then dis charged and packed into the sheaf receptacle by means of the discharge and. packer arms 13. As soon as this operation has been repeated a sufficient number of times it be comes necessary to set in operation the shocker knotter and the needle to bind the shock and subse uently to dump the shock. I will now descri e the mechanism by which these movements are imparted and coordinated.

On the main drive shaft 15 is located a loose sprocket wheel 31 driven by a suitable chain from a sprocket wheel 32 fast on the shaft 33, whichmay be the packer shaft of the harvester binder. This shaft 33 is driven from the shaft 26 of the harvester binder which is, of course, continuously rotating being driven by beveled gearing .from the main shaft 28 of the harvester binder. Sprocket wheels 29 and 30 fast respectively on the shafts 26 and and connected by suitable sprocket chain provide the necessary driving connection. (See Figs. 2 and 3.) At the forward side of the sprocket wheel 31 is located a sprocket wheel 34 fast on a sleeve 35 loose on the shaft 15. This sprocket will ;50 .-after three revolutions of the discharge [and packer arm shaft, that is after nine wheel 34 is connected by a suitable chain with a sprocket wheel 36 secured to the discharge and packer arm shaft 11.

.Between the sleeve 35 and the sprocket wheel 31 is located a driving clutch 37 of a type hereinafter tobe described, by means of which the sprocket wheel 31 maybe given a driving connection with the sleeve for one revolution and then automatically thrown outof gear. The clutch is controlled by an arm 38 suitably pivoted on the spindle 39 or' other convenient part. This arm is connected by a link 40 with a second arm 41 pivoted on any convenientpart and provided with a pin or other projection 42 adapted to engage a groove in the cam 43 fast on the shaft 44 suitably journaled .beneath the bindcr deck. (See-Figs. 3 and 6.) On the end of this shaft is secured a sprocket wheel 45 driven by a suitable chain from the sprocket wheel 46 secured to a-cranked outward extension of and in line with tlieknotter shaft of the binder. (See Fig. 2.)" As the sprocket wheels are in a ratio of one to three, and as.the knotter shaft of the harvester binder revolves 'once for every sheaf every third sheaf, causing the sheaves to be.

discharged from the sheaf receiving table into the shock receptacle in sets of three.

At the rear side of the sprocket wheel'31 a sprocket wheel 47 is located fast on the shaft 15. This sprocket wheel is connected by a suitable chain with the sprocket wheel 48 fast on the sleeve 25 of the shocker knotter hereinbefore referred to. Between the sprocket wheel 47 and the sprocket wheel 31 is located a clutch 49 of a type to be hereinafter described, by means of which the sprocket wheel 31 may be put into driving connection withthe shaft 15.and thrown out oflgear automatically. after one revolution. This clutch is controlled by the arm 50 pivoted on the spindle 39 or other suitable part. A pin or other projection 51 on the arm 50 is adapted to engage the cam groove in the cam 52 fast on the shaft 53 suitably journaled behind the binder deck. On this shaft is secured a sprocket wheel 54 driven by a suitable chain from t e sprocket wheel 55 fast on the discharge and packer arm shaft '11. 'As the sprocket wheels 54 and 55 are in the proportion of three to one the cam 52 e caused to operate the controlling arm "sheaves have been discharged into the shock receptacle. See Figs. 2, 3, and 7. drive shaft '15 is thus rotated one revolution and operates the needle 22 and knotter 24, as

herei nb'efore desei'ibed, binding theshock The main lhe shock is now ready for dumpnected by a suitable chain with the s rocket Wheel 61 on the main shaft 28 of t 1e harvester binder.

A controlling arm 62 is pivoted below the clutch 57 with its shoulder 63 normally in the path of the projection 64 on the clutch dog 65, which is pivoted on an arm 66 se-' cured to the shaft 8. See Fig. 4. The end of the dogis normally maintained in the path of the projection or rollers 67, secured to the sprocket wheel, by means of a suitable spring 68 When the dog is so engaged the sprocket wheel drives the shaft until the projection 64 engages the shoulder 63 when the dog will be I thrown out of clutch and the shaft released.

This is the normal position of the clutch. At the proper time after thebinding of the shock the controlling arm 62 must be moved to release the dog. This is accom lished by means of the pivoted release 69 suitably pivoted adjacent to the clutch and in the path of a finger 70 secured. to the main drive shaft 15. A'crank arm 7]. is secured to the spindle of the pivoted release 69 and is connected by a ivoted link 82 with the controlling arm 62. The finger 70 is so positioned that by the time the main drive shaft 15 has completed one revolution, thus binding the shock, it has rocked and passed by the pivoted release 69, thus rocking the controlling arm and releasing the dog. The clutch being now in gear the shaft 8 is driven from the sprocket wheel 56 and the shock receptacle moved to the dumping position, as hereinbefore described. As it is desirable that there should be a dwell. of the receptacle in this position while it is being drawn away from the dumped shock, I provide the controlling arm 72, which is in a position to engage the projection 64 after one alf revolution of the shaft, thus throwing the clutch out of gear. The clutch remains out of gear until one of the cam projections 7 Son the sprocket wheel 56 presses sidewise the end of the bent arm'74 secured to the controlling arm 72 and thus push the latter away from the projection 64. The dog immediately goes into clutch again and the shaft is driven until the clutch is again thrown out of gear by the projection 64contacting with the shoulder-63 on the controlling arm 62. ,It should benoted that the controlling arms 62 and 72 are loosely journaled on the spindle 75 carried on the framiaand are held 76 arranged in, any ordinary well-known manner.

It will be noted that the release (59 is made of considerable length. This is owing to the fact that it .is necessary to support the main shaft 15, the discharge and packer arm shalt 11, the" cam shafts 4A and 53, in fact-all the parts of the shocker mechanism from the binder deck of the harvester which, ol"

course, is always made adjustable back and forth to suit ditlerent lengths of sheaves.

The clutches 37 and 40 are of precisely similar construction to the clutch 57 just described. There are, however, four projections or pins shown in these clutches, so that the clutches take hold a little quicker. Having set out the construction of the apparatus 1 now briefly set out its mode of operation. The binding cord of the shocker, of course, lies normally stretched between the point of the needle and the knotter, in ordinary knottenc. After three sheaves have been bound by the harvester the discharge and packer arms 13 are set in opera- .tion and these three sheaves which have been lying on the sheaf receiving table are discharged into the shock receptacle, drawing the cord into a loop with them. This operation is repeated three times, the last three sheaves completely filling the recep tacle and being closely packed therein by the arms 13. The knot is now tied by the cooperation of the needle and the knotter and the finished shock dischar ed, as already described. The holding of t e sheaves on the table is necessary in order that they may have su'flicient time to dump the shock and draw the receptacle away from it. The dis charge arm and packers efi'ectually provide for t e proper discharge and packing of the sheaves. They also serve to tear away the sheaves from. one another when the apparatus is working in tangled grain, which is one of-the obstacles to the use of the ordinary sheaf carrier when working in tangled gram.

My needle it will be seen. is entirely independent of the shock receptacle and its proper cooperation with the knotter cannot, therefore, be affected in any way' by the stresses and strains of the latter. rigidly guided and moves on rectilinear lines or with a rectilinear motion thcrecan be no springing of its parts that would all'ect the proper cooperation with the knotter, a

trouble which is encountered with my formertype of needle. it will als be found that the details of the mechanism which I have described are superior in every way to my former construction.
