THRASHING CYLINDER WITH RAD IAL BARS AND SAFETY TEETH Filed Oct. 20, 1936.
Patented Mar. 7, 1939 PATENT OFFICE THRASHING CYLINDER WITH RADIAL BARS AND SAFETY TEETH Agustin Martinez 3., Mexico, D. F., Mexico Application October 20, 1936, Serial No. 106,553 In Mexico November 7, 1935 3 Claims.
This invention relates to a cylinder for thrashing, bruising, and similar machines.
One object of my invention is to provide certain novel features of construction in an element of the type described, which features will be specifically pointed out or will be apparent in the following specification, reference being had to the accompanying drawing, in which Fig. 1 is a lateral view of the whole. Fig. 2 is a schematic view of the radial bars.
Fig. 3 shows a pair of radial bars seen from the front of the cylinder shaft, to completely show the several parts of the whole.
Fig. 4 is a front and Fig. 4a a sectional view of one of the teeth.
' Fig. 5 and Fig. 5a show a detail view of the spacers.
Fig. 6 and Fig. 6a show the cleats that engage the bar of each pair.
Fig. '7 shows detailed views of the radial bars. Fig. 8 is a conventional front view of the whole. With reference to the drawing, the cylinder of my invention comprises a main shaft l in which engages aseries of pairs of radial bars 2 spaced longitudinally of said shaft and being angularly disposed therein in such a way that the ends of the successive pairs of bars are in hellcoidal relationship.
The bars 2 have a longitudinal slit 3 extending from each side of the central opening 4, and each pair of bars, Fig. 3, is arranged closely adjacent by means of a pair of cleats 5 on each side of the shaft engaging the bars of each pair with a bolt 6 passing between said bars drawing the cleats together to form a clamp.
The bars 2 have near their ends perforations 1 equidistant from the main shaft I, and are arranged in longitudinally aligned groups to receive the rods 8 that extend through several aligned groups of perforations.
The rods 8 have threaded ends that pass through the corresponding perforations of rings 9 concentric with the shaft I, which rings form the ends of the cylinder.
Spacer tubes [0 surround the rods 8 and extend from each ring to the nearest radial bar and between the several bars in each line of perforations.
The bars 2 have teeth ll arranged in juxtaposition to their ends, each tooth having an opening I2 receiving the corresponding rod and a smaller opening l3 corresponding with a perforation on the rod to receive a relatively small pin M passing through said tooth and said radial bar, the pin being of sufficient strength to withstand the stresses resulting from normal working conditions but sufficiently weak to break under a predetermined overload. 5
I claim:
1. A cylinder for thrashing, bruising, and similar machines comprising a shaft, a series of pairs of radial bars having central openings receiving the shaft, said pairs of radial bars being spaced 10 longitudinally of said shaft and successive pairs being angularly disposed, the arrangement of parts being such that the ends of the successive pairs of bars are in helicoidal relationship; each of said bars having a longitudinal slit extending 15 from each side of the central opening, the bars of each pair being arranged closely adjacent, with a pair of cleats on each side of the shaft engaging the bars of each pair with a bolt passing between said'bars drawing said cleats together to form a clamp; perforations in each bar near the end equidistant from said shaft, and ar, ranged in longitudinally aligned groups; round rods extending through each of said aligned groups of perforations, said rod having threaded ends, rings concentric with the shaft and forming the ends of the cylinder, said rings being provided'with perforations through which the ends of said rods; spacer tubes surrounding each rod and extending from each ring to the nearest radial bar; and nuts engaging the threaded ends of said rods to hold the parts in assembly.
2. In a cylinder for thrashing, bruising, and similar machines as defined by claim 1, a tooth arranged in juxtaposition to the end of each radial bar, said tooth having an opening receiving the rod, a relatively small pin passing through said tooth and said radial bar at a point radially spaced from said rod, said pin being of suificient strength to withstand the stresses resulting from normal working conditions but suf- 40 ficiently weak to break under a predetermined overload.
3. A cylinder for thrashing, bruising, and similar machines as defined in claim 1, in which the radial bars of each pair are parallel for a certain distance on each side of the shaft, then diverge for a certain distance, then continue parallel for the remainder of the distance to their ends.
