DlSK'FURROW-OPENER FOR'GRAlN-DRILLS.
SPECIFICATION forming part of Letters Patent No. 737,151, dated Aiigiist 25, 1903.
Application filed March 12, 1903.
To ctZZ whom it may concern:
Be it known that I, DAVID B. SALTSMAN, a citizen of the United States, residing at the city of Dowagiac, in the county of Cass and State of Michigan, have'invented certain new and useful Improvements in Disk Furrow- Openers for Grain-Drills, of which the following is a specification.
. This invention relates to improvements in grain-drills,and particularly to improvements in disk furrow-openers therefor, although the disk structure is adapted for use in other relations.
One object of the invention is to provide a very narrow bearing or support for a disk.
A further object is to provide a compact and efficient structure for a double-disk furrow-opener. I Y
Still further objects pertaining to details of construction will definitely appear in the detailed description to follow.
I'accomplish the objects of my invention by the devices and means described in the following specification.
Theinven tion is clearly defined and pointed out in the claims.
A structure embodying the features of my invention is fully illustrated in the accompanying drawings, forming a part of this specification, in which-- Figure 1 is a detail side elevation view of a double-disk furrow-opener embodying the features of my invention. Fig. 2 is a detail sectional view taken on line 2 2 of Fig. 1 looking down. Fig. 3 is an enlarged detail side elevation view of one side of the boot, showing the supporting projection to which the disk-bearing is attached. Fig. 4 is a detail interior elevation view of the disk and its bearing detached with the attaching-bolt thereforremoved. Fig. 5 is a detail perspective view of the bearing-block O with the. threaded ring 0 in position thereon.
In the drawings similar letters of reference refer to similar partsthroughout' the several views.
Referring to the lettered parts of the drawings, the boot Ais of a usual and convenient form provided with a bracket in front to which the draw-bar A is connected. At the front side of the lower end of the boot A is the boot A are lugs e e.
Serial No. 147,414. (No model.)
To the outside of the disks -]3 are securedbroad shallow cup-shaped caps B by suitable rivets, bolts, or otherwise. The interior of these caps are provided with bearing-surfaces to engage upon the bearing-surfaces of the blocks 0. Rings 0 are screw-threaded to fit into the inner sides of the caps B, thereby forming a casing which embraces the head of the block 0. The threads on these rings 0 are right and left hand, so that theirrotation on the bearings, due to the progress of the disk through the ground, will constantly tend to draw them tighter into the caps B. These rings 0 are provided with projecting lugse', and projecting from the lower end of When it is desired to release the bearings, a bar, as E, (indicated by dotted lines in Figs. 1 and 3,) may be inserted between the lugs e e, so that it will engage the lug e on the disk, and upon the rotation of the disk backwardly the ring will be unscrewed from the cap, thus releasing' the bearing. It is evident that the hearing maybe assembled by turning the disk forwardly in the manner in which it would ;be operated by the progress of the disk through the soil. This construction provides an efficient means for properly opening and closing the bearing-casing. The bearing is very thin and fiat and supports the disk in a secure manner. This arrangement also places the bearing in aprotected position. The oil-passage a comes down in front of the boot into a cavity at the center, from which oil is distributed in both directions to the bearings, thereby insuring the proper lubrication of the bearing at all times without danger of wasting the oil and also insuring the complete lubrication at that point. I desire to remark in this connection that my invention is capable of being used in connection with a single-disk furrow-opener or in any disk structure for similar purposes, when of course it would not be necessary to provide the special means of coupling the ring to the side of the boot for the purpose of removing the hearing from the disk. I also desire to remark that my improved bearing is adapted for use in connection with the concavo-convex disks frequently used as single-disk furrow-openers and on harrows, all of which will readily appear from an inspection of the drawings.
I believe I have shown the structure in its most approved form and with the best arrangement for the delivery of the oil to the hearing; but I am aware that the details can be considerably modified without departing from my invention, and I believe that other means might be satisfactorily adopted for the introduction of oil to the hearing. I also desire to remark that while it is most convenient and expeditions to secure the ring 0 in place by screw-threads on its periphery that other means might be efiectively adopted for that purpose, although I desire to claim the specific features I have shown as being superior to any other on account of their great compactness and simplicity and ease of manufacture.
Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is-- 1. The combination of the boot A with a projection A to the front thereof; bearingblocks 0 O terminating on their outwardlyprojecting surfaces in suitable bearing-heads; furrow-opening disks B B; caps B B with internal bearing-surfaces opening inwardly secured thereto; closing rings 0 O screwthreaded to fit into the innersides of each of said caps, lugs e on the said screw-threaded rings, and lugs e e on the boot coacting for the purpose specified.
2. The combination of the boot A with a projection A to the front thereof; bearingblocks 0 C terminating on their outwardlyprojecting surfaces in suitable bearing-heads; furrow-opening disks B B; caps B B with internal bearing-surfaces opening inwardly secured thereto; closing rings (1 C screwthreaded to fit into the inner sides of each of said caps, coacting for the purpose specified.
3. The combination with a frame,0f a bearing-block having a disk-like head secured thereto; a casing constructed of two parts, inclosing said head and mounted to turn on same, and a disk secured to the outer edge of said casing.
4. The combination with a frame, of a bearing-block having a disk-like head secured thereto; a casing made in two sections located on opposite sides of said head and inclosing the same, and adapted to turn freely thereon; and a disk secured to said casing.
5. The combination with a frame of a bearing-block having a disk-like head secured thereto and having a journal on its side adjacent to said frame; a plate having a central opening mounted on said journal; a bearing-cap mounted to turn on said head; a disk secured to the outer edge of said cap; and means for detachably securing said plate to said cap.
6. The combination of a disk perforated at its center; a shallow cap on one side of the disk; a disk-like bearing-head with suitable means of attaching; and a screw-threaded ring fitting within the cap and adapted to embrace the bearing-head, for the purpose specified.
7. The combination of a disk open at its center; a cap fitted to one side of the disk having a bearing-surface on its inner side; a disk-like head adapted to fit the said bearing; and a ring embracing the said head and detachably secured within the cap, for the purpose specified.
8. The combination of a disk open at its center; a cap fitted to one side of the disk having a bearing-surface on its inner side; a disk-like head adapted to fit the said bearing, and a ring embracing the said head and secured within the cap, for the purpose specified.
In witness whereof Ihave hereunto set my hand and seal in the presence of two witnesses.
DAVID B. SALTSMAN. [L. 8.]
