IMPROVEMENT IN SEEDING-MACHINES.

Specification forming part of Letters Patent No. 8,209, dated .Inly 8, 1851.

To all whom it may concern:

Be it known that we, SAMUEL PENNOGK and MORTON PENNOGK, of Kennet Square, in the county of Chester and State of Pennsylvania, have invented certain new and useful Improvements in Seeding-Machines; and we do hereby declare the following to be a full and exact description of the construction and operation thereof, reference being had to the annexed drawings, making part of this specification.

In the drawings, Figure 1 represents an elevation of the machine, the de 'iositing-tubes being elevated. Fig. 2 is a vertical longitudinal section through the same, the depositing-tubes being lowered with their curved levers. Fig. 3 is a vertical transverse section of the ma chine through the hopper. Fig. 4: is a rear view, showing the eccentric for actuating the hopper-grates, the curved levers, and leverframe. Fig. 5 is a plan of one of the hoppergrates. Fig. 6 is a vertical section of Fig. 5, showing the distributing-cylinder. Fig. 7 is a transverse section of Fig. 6. Fig. 8 is an end view ot'thecylindrical cap,showinginclined projections. inclined recessed washer, which fits theinclined projections of the cylindrical cap. Fig. 10'is a distributing-cylinder, showing a modification of the device for holding the cylindrical cap when adjusted to any size or form of seed-receptacle. Fig. 11 is an end view of Fig. 10.

Fig. 12 is a longitudinal section of a distributing-cylinder, showing another modification of the device for holding the cylindrical cap. Fig. 13 is an end view of Fig. 12. Fig. 14 is a modification of the distributing-cylinder. Fig. 15 is a vertical section of the same. Fig. 16 is a plan of the drag-bar, with its depositingtube, showing its connection with the front 'beam of the frame. Fig. 17 is a side elevation 'of Fig. 16, showing the position of the depositing-tube when forming the drill and the triform holding-lever. Fig. 18 is a view of the opposite side of the depositing-tube and a section of the drag-bar. Fig. 19 is a front view of the detachable double arm of the drag-ban, Where the same letters of reference occur on the several figures they indicate the same parts.

, This machine in its general construction and arrangement of parts is like our seeding-machine on which a patent was granted on the Fig. 9 is a side and inside view ot'the 12th day of March, 1841, and reissued on the 30th day of October, 1849.

The improvements which we now desire t have patented consist in the employment of sliding grates to which the distributing-cylinders are attached, and with which they are made to move back and forth in engaging with and disengaging the same from the propellingshaft.

Our improvement likewise relates to the employment of short axles projecting from and forming part of the hubs of the propellingwheels and turning in boxes secured to the side beams of the frame.

Our improvement further relates to placing a helical spring within the distributing-cylinder for expanding the cylindrical cap-for increasing the size of the seed-receptacleswhen required.

Our improvement also consists in forming the bottoms of the seed receptacles or cells of the distributing-cylinders by the employment of a plain cylindrical ring placed within the same.

Likewise our improvement consists in certain arrangements and devices for adjusting and holding the oblique recessed cylindrical cap in connection with the oblique recesses of the cogged portion of the cylinder.

Our improvement likewise relates to suspending the depositingtubes to projecting arms of the drag-bar in such a manner that the depositing-tubes shall be made to turn frontward during the backing of the machine to clear obstructions, or for any other purpose, thus dispensing with the necessity of raising the same, and also by which the depositingtubes may be detached from the drag-bar with facility, when desired, by simply moving them frontward to nearlya horizontal line with the drag-bar, and giving them aslight lateral movement, which disengages thejournal-pius from the drag-bar, and allows the depositing-tubes to be removed.

Our improvement also. relates to the employment of a triform holding-lever attached to the projecting-arms of each drag-bar in such a manner that its hook-branch shall be made to fit over the wooden pin secured in the rear portion of the depositing-tube for holding it in its proper position during the operation of forming the drill and depositing the seed,

and also for allowing the attendant to disengage said trit'orm holding-lever from the pin when an obstruction is visible, and thus allow the depositing-tube to turn rearward and clear itself of the obstruction, and the pin saved from being broken and the progress of the machine not interrupted, the triform holding-lever being made to assume its proper position with the pin when the depositing-tube shall have cleared the obstruction.

Our improvement likewise consists in effectin g the frontward movement of the depositingtube when it shall have been relieved from the obstruction by the action of tril'orm lever upon a cam projecting from the upper portion of the depositing-tube.

Our improvement consists, finally, in the employment of a double detachable arm, in combination with the drag-bar by which it is suspended to the frame, and also by which said double arm may be detached with facility from the drag-bar and eyesor loops of the transverse beam of the frame.

The grates A, Figs. 3 and 5, to which the distributing-cylinders B are attached by hanging-arms a a, (secured to the grates by being dovetailed and keyed,) are confined to the bottom of the hopper T by grooved plate 0 c, Fig. 3, into which their edges fit, and are permitted to move back and forth when engaging the cog-wheel of the distributing-cylinder with or disengaging it from the propelling-shaft i thus keeping the distributing-cylinder in the same relative position with the opening A in the grate, whether in or out of gear.

' O O are the curvedlevers,to the ends of which the triform holding-levers L of the depositing-tubes are attached by the usual chains, 12, for elevating said depositingtubes. These curved levers (l are attached, by means of jointed arms d d, to a horizontal fulcrum-rod, e, secured to the rear transverse timber of the frame by boxes D,(one to each lever,) and are provided with notchesff at their lower ends, which catch overholding-plates g, projecting from the hopper, for sustaining the depositingtubes when elevated.

The lower end of each jointed arm 61 of the curved levers O is provided with an eccentric, h, from which projects a connecting-rod, E, which unites the hopper'grate A with eccentric h, and thus the movement of the grate of the distributing-cylinder is effected by the eccentric simultaneously with the elevation or depression of the depositing-tube.

F is the 1ever frame,havingahandle, f and connected to the fulcrum-rod e, and provided with a horizontal transvere turning crank-rod, 9 secured in the arms of the lever-frame F in such a manner as to catch against the arms d when in the position seen in Fig. 2, and elevate the depositing-tubes, as seen in Fig. l,

and when said lever-frame is in. the position seen in Fig. 2, the depositing-tubes may be depressed simultaneously by simply depressing the short handle 9 Fig. 4, which turns the crank-rod g frontward against the ends of the holding-plates g of the hopper; or the depositing-tnbes may be elevated or depressed separatel y, if required.

The supporting and propelling wheels G are provided with short axles G projecting from and forming part of the hubs and turning in boxes H, secured to the under side of the side beams of the frame, and confined by nuts 'i i or otherwise, one of said short axles G being provided with a pinion, H which matches with one of the pinions i on the propellingshaft i for communicating motion thereto.

The seed receptacles or cells of the distributing-cylinders shown in Figs. 3, 6, 10, and 12 are the same as those in the distributing-cylindersof our patentof the 11th of February, 1851. The manner, however, ofadjnsting and holding the oblique cylindrical cap I is different and more effectual, and consists in providing its end with three or more projections, I, having their outward sides, 1 made inclined or oblique, as shown in Fig. 8, corresponding in obliquity to the recesses of its periphery, and placing upon the longitudinal screw-shaft J a washer, K, having the same number of oblique recesses It, and corresponding in inclination to the projections I of the cylindrical cap I, into which they fit, while the projections k of the washer K fit the openings 1 between the projections 1 The object of this is to form the bearing against the cylindrical adjustive cap I, at right angles to the bearing of the oblique recesses which form the seed-receptacles, so that when the oblique recesses of the cylindrical cap shall have been adjusted in relation to the adjacent recesses of the cogged portion of the cylinder, and the oblique recessed washer K clamped against the oblique projections I by means of the clamp-nut 1 upon the screw-shaft J, the cylindrical cap will be held firm, and effectually prevented from slipping during the operation of the machine.

The oblique recessed washer K is prevented from turning in the direction of the cylindrical cap, when decreasing the size of the seedreceptacles,when clamping it against said cylindrical cap by means of a pin, m, Fig. 6, projecting from the screw-shaft J into one of the recesses 70 of said washer K, against which the shoulder or projection is formed by said recess acts while clamping the cylindrical cap.

Figs. 10 and 11 represent another device for producing the pressure upon the oblique surfaces of the seed-receptacles of the distributingcylinder, at right angles thereto, and consists in scalloping the end of the cylindrical cap L and forming therein two segmental slots, n a, through which pass screw-bolts 0 at right angles to the oblique recesses or cells, and screw into the cogged portion of the cylinder, the

Figs. 12 and 13 represent another device for holding the cylindrical cap M of the distrib uting-cylinder, and consists in providing the oblique recessed cylindrical cap M with a pin, m projecting centerward therefrom, near its recessed periphery,into an opening formed in the inner cylinder, 12 which forms the bottoms "of the seed-receptacles, and which is made solid except the bore for the screw-shaft M. In the cogged portion of the cylinderis formed asegmental slot, 0 through which the shank of a clamp-sere,w,0 passes into theinner solid cyl-. inder, a and is for the purpose of clamping said inner cylinder to the cogged portion of the distributing-cylinder, and thus, by means of the pin m the cylindrical cap M is prevented from turning in either direction when adjusted to any required sized receptacle and clamped by the clamp-nut p on the screw-shalt. When it is desired to increase or diminish the size of the seed-receptacles the clamp-nutp is turned to the left, and the holding-screw 0 loosened,

and the cylindrical cap turned in either direction with the inner cylinder, a and secured by the clamp-nut and holding-screw.

Figs. 14 and 15 represent distributingcylinder withlongitudinal parallel recesses 00 and projections 01: in such a manner that they shall be made to fit within each other and form a double row of seed receptacles or cells, which may be increased or diminished in size by means of a clamp-nut, .00 on the screw-shaft m and a helical spring, 00 placed within the cylinder and made to bear against said cylindrical cap N, for expanding or moving the same outward to increase the size of the receptacles when the clamp-nut is unscrewed. Within the cylindrical cap is placed a cylindrical ring, x for tormin g the bottoms of the seed-receptacles.

The depositing-tubes represented in Figs. 17 and 18 are in form and construction the same as those described in our patent granted the 10th day of December, 1850, being provided with a reversible point, 0,. the improvement now claimed consisting in suspending the depositing-tubesU to the armsjj of the drag-bar,

j by means of two journal-pins, q q,projecting from either side of the upper portion thereof in such a manner that the depositing-tubes shall be made to turn forward upon their jourrial-pins q q during the receding movement of the machine.

One of thejournal-pins, q, is provided with a cog, g which is made to fit an opening in the arm j of the drag-bar when the depositingtube shall be turned frontward to nearly a horizontal line, for the purpose of disengaging the same from the drag-bar, when desired, by impartingto the depositing-tube a lateral movement, when the cog will pass into the opening in the arm of the drag-bar, and thus disengage its opposite journal-pin, q, and permit the depositing-tube to be detached therefrom, one of the arms j of the drag-bar being bent outward for that purpose, as seen in Fig. 16.

L is the trifurcated holding-lever attached to the ends of the twoupward-eurved arms j of the drag-bar by two pins, 6 i projecting from a long and short arm, 1' t"*, of the trit'urcated holding-lever, upon which it is permitted to turn when required.

Z is the central hook-shaped branch of the trifurcated lever L, projecting downward and inward between two ears, 1 which project rearward from the upper portion of the depositing-tube U, and provided with a series of holes into which a wooden pin, 0 is inserted, the end of said central branch, libeing notched in such a manner and sustained in such a position as to catch over the wooden pin 0 and hold the depositing-tube firmlyin the required position during the operation of forming the drill, and at the same time allow the attendant to disengage it therefrom, when he shall discover arock or other obstruction in the way, by simply laying hold of the curved lever O, to which it is attached by the chain 1)., and elevating it sufficiently to disengage the hook i of the triform lever L from the pin 0 when it will be permitted to turn rearward and clear itself of the obstruction, and thus save the wooden pin from being broken and render the progressotthemachineuninterrupted. Should, however, the obstruction be not discovered, it is designed that the wooden pin shall break rather than the trifurcated holding-lever or depositing-tube.

The upper portion of one side of the depositing-tube is provided with a cam-shaped projection, r, as seen at Fig. 17, against which the long arm i of the trifurcated lever L is made to act, when the depositing-tube U shall have been turned rearward from any cause,'for the purpose ofthrowing it frontward in its proper position to allow the hook-branch l of the triform lever to engage itself with the pin, the

holes into which the pin is inserted being on a circle scribed from the journal-pin q of the depositing-tube, and the downward movement of the holding-lever L being governed by a pin, 1, Fig. 18, projecting from one of the arms of the drag-bar beneath which the end of the short arm i of the holding-lever catches and sustains it in such a position that the notched end will be on the circle scribed from the center of the pin q, irrespective of the hole into which it is inserted, the relative angle of the depositing-tube with the drag-bar being governed by the position of the pin in either of the holes aforesaid.

The upward movement of the trifurcated holding-lever is governed by a pin, 1' projecting from the arm of the drag-bar, upon which the long or cam arm i strikes on the ascent of the holding-lever, in disengaging it from the pin 0 or elevating the depositingtube, and thus prevent it from turning entirely over, which would cause the upper side of the long arm to catch behind the cam or projection 1' of the depositing-tube and prevent the proper action of the same.

The frontward end of each drag-bar is provided with a double arm, 1?, having a vertical oblong opening, P, in its central portion, into when secured in the eyes or loops R, attached to the front transverse beam of the frame, and are provided with shoulders or projections S S on their under sides, one of which is made to enter an opening, 5-, in one of the eyes or loops B, when said double arm P is turned half a revolution upward and frontward, by simply moving the double arm laterally with its projection S into the opening 8, and thus disengage the opposite end thereof from the eye or loop R and allow it to be detached therefrom.

It will thus be seen that nearly every section of this seeding-machine may be detached and put together with the greatest convenience and facility.

Havingfully described the construction, use, and operation of our several improvements on the seeding-machine, what we claim therein as new, and desire to secure by Letters Patent, 1s-

1. The employment of the oblique recessed washer K, in combination with the cyliudri cal cap I, provided with inclined wings or projections 1 which match with the oblique recesses 7c of the washer K in such a manner that the pressure produced thereupon shall securely hold the cylindrical cap in the required position when adjusted to increase or diminish the size of the seed-receptacles.

2. Scalloping the end ofthe cylindrical cap L of the distributing-cylinder, and using in connection therewith clam p-screws 0 0 for bolding the cylindrical cap in therequired position.

3. The employment of the pin m Fig. 12, or its equivalent, when used in connection with a clamp-screw, 0 and interior cylindrical cap, M when properly adjusted to increase or diminish the size of the seed-receptacles.

4. Providing one of the journal-pins, q, of each depositing-tube U with acog, g which is made to fit an openinginthe armj of the dragbarj when it shall be turnedfrontward, nearly horizontal, for the purpose of detaching the depositing-tube from the drag-bar] with facility, as described, and shown in Fig. 18.

5. The employment of the trifurcated holding-lever L, in combination with the drag-bar j and suspended depositing-tube U, for the purpose of holding the depositing-tube in its proper position during the operation of forming the drill and depositing the seed, and by which said trifurcated holding-lever L may be disengaged from the pin 0 when an obstruction is visible and allow the depositing-tube to turn rearward when it shall have been struck, and thus save the pin 0 from being broken, and this trifurcated holding-lever we claim,or its equivalent.

6. Causing the depositing-tube to assume its proper position after it shall have cleared the obstruction, by the action of the long arm i of the trit'urcated holding-lever L upon the cain or projection 1' of the depositing-tube, and this we claim as in the arrangement herein described and represented.

7. So combining a separate double arm, P, with the frontward end of each drag-bar j that it may be detached therefrom as well as from the eyes or loops It of the front transverse beam of the frame, as described in the specification,-and shown in the drawings at Figs. 16, 17, and 19.

In testimony whereof we have hereunto signed our names before two subscribing witnesses.
