SPE(JIFIGATION forming part of Letters Patent No. 752,576, dated February 16, 1904.
Application filed May 29, 1903. Serial No. 159,327. (No model.)
To all whom it may concern.-
Be it known that 1, ROBERT N. MGOLANA- HAN, a citizen of the United States, residing at Elreno, in the county of Canadian and Territory of Oklahoma, have invented a new and useful Improvement in Threshing-Machines, of which the following is a specification This invention relates to threshing machines, and particularly to the cylinders and concaves of such machines; and it has for its object to provide means whereby the insertion of teeth into the cylinders and concaves shall be facilitated, whereby the durability and efficiency of the construction shall be increased and whereby in a general way the simplicity, durability, and efficiency of the device shall be increased.
My invention consists in certain improvements in the construction of the teeth for the cylinder and concave and also in the improved construction of said cylinder and concave which is necessitated by the improved construction of the teeth, whereby the latter shall be retained inposition securely and in such a manner that when Worn or broken theymay be conveniently removed for the purpose of being replaced by new ones.
With these and other ends in view, as will appear as the nature of 'my invention is more thoroughly understood, the invention further consists in the improved construction, arrangement, and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.
In the accompanying drawings, Figure l is a plan view of a threshing-machine cylinder constructed'in accordance with the principles of my invention, a number of the teeth and securing-slats having been removed. Fig. 2 is a transverse sectional view taken on the line Fig. 3 is a longitudinal sectional view taken through a part of the cylin- .der on the line 3 3 in Fig. 1., Fig. t is a sectional View taken through a concave constructed according to my invention. Fig. 5 is a perspective view showing one of the teeth removed.
Corresponding parts in the several figures are indicated by similar numerals of reference.
1 designates a threshing-machine cylinder which is composed of the heads 2 2 and slats 3 3, secured exteriorly upon the heads by means of annular rims or tires 4 1, which may be secured by means of bolts or rivets 5, extending through the slats and through the flanges 6, formed upon the outer sides of the heads. Interior and exterior auxiliary bracing-rings 7 8 may be employed at intermediate points at suitable distances apart, and these auxiliary bracing-rings may be connected with each other and with the slats 3 by means of bolts or rivets 9.
The slats 3 are uniformly wedge-shaped and areeach provided at one of their edges with a plurality of recesses 10, forming square sockets. The teeth, which are designated 11, are of ordinary or conventional construction as regards their outer or working parts. Their inner ends, however, are provided with shanks 12, adapted to engage the recesses or sockets l0, and with laterally-projecting shoulders 13,
fitting tightly against the under sides of the slats 3. Thus the teeth in order to connect them with the slats are simply inserted into inner ends abutting against the under sides of the slats and the shoulders 14 at the intersection of the shanks and the outer Working ends of the teeth abutting upon the outer sides of the slats, the shanks of the teeth and the notches 1O obviously being of uniform size, the said shanks being exactly flush with the edges of the slats 3.
To secure the teeth in the notches of the slats 3 I provide aplurality of slats 15, tapered oppositely to the permanent slats 3 and inserted between the latter from the end of the cylinder at which the pointed ends of the slats 3 are disposed. These intervening slats 15 are of such a size that when placed in position between the slats 3 they will form a continuous unbroken surface and will abut tightly upon the shanks of, the teeth, which havebeen fitted in the notches of the slats 3. These movable slats 15 when inserted tothe proper position are secured detachably by means of bolts ICC slats 15 for the purpose of repairing the cylinder to the extent of providing the same with new teeth in place of those that may have been injured or broken by long-continued use.
Ihave thus far described the invention as applied to a threshing-machine cylinder; but.
it is obvious that, as shown in Fig. 4, the invention may with equal advantage be applied to a concave, the oppositely-pointed wedgebars being used to form, respectively, the bars of the concave and the holders, by means of which the teeth are secured in the concave bars. In this instance the concave bars are designated 3, the notches therein 10 and the wedge-shaped holding-bars 13.
The operation and advantages of this invention will be readily understood from the foregoing description taken in connection with the accompanying drawings.
It will be seen that by simply loosening and detaching one or more of the wedge-shaped holding-bars the teeth may be removed from the adjacent tooth-bar and replaced with new and perfect ones, the entire operation being performed very easily and in much less time than would be possible by the modes of con struction now generally resorted to.
Having 'thus described my invention, I
claim 1. In a device of the class. described, the combination of suitably-supported wedgeshaped tooth-holding bars having notched edges and intermediately-disposed, oppositelywedged holding-bars.
2. In a device of the class described, a-pluing said bars in position with relation to each other, teeth mounted in the notches of said bars, intermediately disposed, oppositelywedged holding-bars, and means for securing the latter in position detachably.
4. In a device of the class described, a pluralityof notched tooth-holdingbars, supporting means for the same, teeth having shanks engaging said notches and shoulders abutting upon the outer and inner sides of said bars, intermediately-disposed wedge-shaped holding-bars engaging the edges of the tooth-holding bars, and means for securing the wedgeshaped holding-bars detachably in position.
5. The combination with holding means comprising permanently-secured wedges having notches in the edges thereof, and detachably-secured oppositely-pointed wedges introduced between said permanently-disposed wedges, ofteeth having shanks engaging the notches in the permanently-disposed wedges and provided with shoulders abutting upon the outer and inner sides of said permanentlydisposed wedges.
6. In a device of the class described, the combination ofsupporting means, wedge-bars permanently supported and spaced equidistantly from each other and provided with notches in the, edges, thereof, means forse? curely connecting said Wedge=barswith the supporting means, intermediate, slidableope positely-pointed wedges, means fonsecuring the latter in position detachably, and tooth members clamped betweensaid stationary and detachable Wedge members.
In testimony that I claim the foregoing as my own I have hereto afii ed-my signature in the presence ,of two. witnesses.
ROBERT Y N. MOOLANAHAN.
