CUTTING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 642,485, dated January 30, 1900.
Application filed May 31, 1898. Renewed January 3, 1900. Serial No. 292. (No model.)
To all whom it may concern.-
Be it known that I, SAMUEL PIERSON, of Hardesty, in the county of Beaver and Territory of Oklahoma, have invented a new and Improved Cutting Apparatus, of which the following is a full, clear, and eXact description.
This invention is a cutting apparatus for mowers and other harvesters; and it embodies certain improvementsin the arrangement and construction of the elements of these cutting apparatus by which they are rendered effective and durable in operation and by which they may be easily repaired.
This specification is the disclosure of one form of my invention, while the claims define the actual scope of the invention.
Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar characters of refererfce indicate corresponding parts in all the figures.
Figure 1 is a plan view of the invention. Fig. 2 is a sectional view on the line 2 2 of Fig. 1. Fig. 3 is a sectional view of the invention on the line 3 3 of Fig. 1. Fig. 4 is a similar view on the line 4 4 of Fig.1. Fig. 5 is a plan view of the invention with parts removed, and Fig. 6 is a perspective view of one of the finger-bars.
The shoe 10 of the cutting apparatus is elongated longitudinally with the machine, so as to present a broad bearing-surface, and thus pass more easily over the ground. The bottom of the shoe 10 is provided with a slideplate 11, which engages the ground and serves to protect the main portion of the shoe. The rear end of the shoe 10 .has upturned lugs 12,
against which upturned lugs 14 of the slideplate 11 bear. These lugs are bolted together in pairs, whereby to jointhe parts 10 and 11. The front end of the slide-plate 11 is joined to the shoe 10 by means of rivets or other fastening devices passing through them, as shown best in Fig. 3.
Formed transversely in the shoe 10 is a groove 15, in which slides the enlarged inner end 16 of the sickle-bar. This end 16 of the sickle-bar is flat, so as to lie snugly in the groove 15. Riveted to the top face of the end 16 of the sickle-bar and approximately at the middle thereof is a sickle-head 17, having a ball 18, to which the pitman 19 is connected.
By these means a reciprocal motion is imparted to the sickle-bar. Rigidly secured bylinking or otherwise with the top of the shoe 10 are two plates 20, which range transversely of the shoe and which overhang the groove 15, so as to engage the top surface of the end 16 of the sickle-bar. The sickle-head 17 is located between the contiguous edges of the plates 20, as best shown in Fig. 3, and by these means the sickle-bar is held so that it may reciprocate transversely when in opera tion; but the bar is prevented from lateral deviation as well as displacement from the groove 15. Each plate 20 is provided with a duct 21, which leads to the top of the end 16 of the sickle-bar. These ducts 21 respectively communicate with cups 22, standing on the plates 20. These means serve to continually lubricate the end 16 of the sicklebar. The oil-cups 22, as well as the inner end of the sickle-head 17, are covered by a hinged casing 23, which'is mounted. on one of the plates 20 and which is held in closed position by a fastening device 24, carriedon the other plate 20. The casing 23 is provided with openings 25 at its top, through which the upper ends of the oil-cups 22 respectively project, so as to permit the caps of the oil-cups to be unscrewed and the oil-cups to befilled without raising the casing 23. This casing 23 serves not only to protect the oil-cups, but to prevent the falling of dirt and other foreign matter upon the inner portion of the sicklehead 17, and thus avoids clogging up the sickle-bar with dirt and dust. Located on the plates 20, outward from the casing 23, is a hood 26, which has its inner end open, so that the pitman 19 may pass therethrough and which inclines downward toward its outer end. The hood 26 is mounted to swing on lugs 27, carried at the outer extremities of the plates 20, and is held at its inner end by means of fastening devices 28, carried, respectively, by the plates 20. This hood 26 alsoserves to prevent the falling of foreign matter upon the sickle-head 17, and consequently lengthens the life of the parts coacting therewith, by preventing the cutting out of the same.
Joined rigidly to the outer edge of the shoe 10 and running outward therefrom, as usual, is the fin ger-bar 29, which has the shanks 30 of the fingers bolted to the under face thereof. The fingers project forwardly from the bar 29 and are provided with oppositely-extending transverse projections or shoulders bearing against the forward edge of the finger-bar. These projections, as best shown in Fig. 4., extend longitudinally with the finger-bar and abut against each other, so as to form means for strengthening the fingers against lateral displacement and also to form a track on which may run the outer or sickle-carrying portion 32 of the sickle-bar. The finger-carrying portion 32 of the sickle-bar has the sickles 33 riveted thereto. The sickles 33 work over the fixed ledger-plates 34, which are carried, respectively, by the fingers. Pivoted to the front portion of each finger is a swinging top section 35. These sections are flat and of a width equal to the width of the fingers. The top sections extend rearward over the respective fingers and are provided at their rear and free ends with downwardlyprojected threaded studs 36, having nuts 37, by which they may be joined to the fingerbar 29. By means of the nuts 37 and threaded studs 36 the positions of the top sections 35 with reference to the sickle-bar and sickles may be regulated so as to adjust the parts in a manner to be effectively operated.
In assembling the parts of the cutting apparatus the fingers are placed in such relative position and the sickle-bar is given such a scope of reciprocation that the sickles will be forced entirely through the fingers,and th us clear out from the fingers any matter that may accumulate therein, which matter would otherwise tend to clog the cutting apparatus. In mowing apparatus the grass frequently exudes a gum which clogs in the fingers and prevents the effective operation of the knives or sickles but by causing the knives to move entirely through the fingers from one side thereof to the other this material is continually cleaned out and the disadvantage referred to isavoided. The portion 32 of the sicklebar, as best shown in Figs. 2 and 4, runs directly over the projections 31, which pro jections being arranged in alinement with each other form a continuous bed for the support of the sickle-bar and also prevent the fingers from being displaced. These projections abut directly against the finger-bar and are braced and strengthened thereby. The whole arrangement forms an exceedingly compact and rigid structure, answering the intended purpose with great eificiency.
It will be seen that by my invention I provide an extra long sickle-head and a correspondingly wide shoe, thus affording a large slide-surface and reducing the usual excessive friction at that point. The construction and arrangement keep the cutting edges of the knives and guards in true alinement by preventing the wear in the sickle-head and lengthening the period of its usefulness.
Various changes in the form, purpose, and minor details of my invention may be resorted to without departing from the spirit and scope thereof. Hence I do not consider myself limited to the exact construction herein shown, but am entitled to all such variations as come within the scope of my claims.
Having thus described my invention, I claim as new and desire to secure by Letters Patent I 1. The combination of a shoe, a sickle-bar mounted thereon, an oil-cup capable of carrying a lubricant for the shoe, and a casing mounted to swing on the shoe and having an opening receiving a portion of the oil-cup.
2. The combination of a finger-bar, and a finger attached thereto and comprising a main portion connected directly with the fingerbar, and also comprising a top section fastened to the main portion and extending longitudinally therewith and capable of adjustable connection with the finger-bar.
SAMUEL PIERSON.
