DOUBLE ROLLER PULVERIZER Filed May 8. 1929 Patented Aug. 75,193()y Unirse srArs' rar WILEY J. DUNHAM, or nanna, onro, Assrsnon To Tran nonnen ooMrANY, Orsenna,
onro, A conronarron or onto y y t Y :DOUBLE-ROLLER, PULVERIZER Application :filed May 8, 1929. Serial No. 361,303.
These and other objects, as will hereinafterv appear, are accomplished by this invention which is fully described in the following" specification, and shown in the accompanying drawings in which-4 Figure l is a side elevation of a pulverizer embodying the invention; and
Fig. 2 is a partial enlarged section on the line 2-2 of Fig. 1 showing the connection.
between the weight carrying frame and a n roller carrying frame.
The embodiment illustrated comprises a Vdouble roller soil pulverizer having frame members 10 which are secured at each end to a weight carrying frame 11, a tongue 12er the like being secured to the frame member 10 intermediate to members 11. Each frame member 11 has pivotally mounted thereon a roller carrying frame 13, each of these frames having bearings 14 and 15 in which are journalled shafts (not shown) which carry the soil pulverizing rollers 16 and 16 respectively.
The weight carrying frames 11, one at each end of the pulverizer, are preferably symmetrical with respect to a central vertical line, and are provided with lateral cylindricalextensions 18 and 19. One of these extensions as 19 is adapted to lit into a socket 20 in the roller carrying frame 13, while the cylindrical extension 18 is adapted to rock infront of an abutment 21 which is arcuate in form, and substantially concentric with the aXis of the socket 2O and of the cylindrical eXtension 19. y
The frames 11 and 13 are preferably made of cast-iron, and in order to prevent encessive wear between these cast-iron members I have provided Wearing strips of steelr or the like 22 and 23 which lie between these frames. The steel upon cast-iron thus produces much less wear than would `be the case were the Vcast-iron to rub directly upon cast-iron, and
moreover the renewable wearing stripsv are ycapable.v of Veasy and inexpensive renewal.-
l/Vith theparts in the-position shown inli y. i
1,*the frame 11 is disengagedfrom the frame 13 rocking the former backin a clockwise direction about the ball7 19 as anaXis until the extension 18 will pass out over the top of thek strip 23when frame 11 can be'llfted bodily out of engagement with the frame13. These frames are assembledbyvareverse operation, thatis, by rocking the'member 11 back, inserting the ball 19 intothe socket 20,
andthen rocking the member 11 to the left' about the center of the ball 19 as an axis. The
' side of the member 13 is preferably'shown out away at 13a. v
Thus will beseen that a very simple and` substantial vflexible connection has :been provided between the frames 11 and l13, and one which. can be economically manufactured, and onein which the wearing parts may be easily and inexpensivelyl replaced.`
While 'I have shown and described-but a single embodiment of my invention, it is understood that itis capable of many modifications. Changes, therefore, in the construction and arrangement may be made which doL not depart. from the spi-rit and scopei of the invention as disclosed in the appended claims.
l: claim: v i
1. ln a soilvpulverizer, a weight carrying l frame, and roller carrying frames disposed below the weight carryingframe and rockably mounted thereon, said mounting includling a concavely arcuate socket in one frame and a complementary convenlyarcuate portion in the other fra-me and abutting surfaces in said members concentric with said socket for retaining said members assembled.
2. In a soil pulverizer, ay weight carrying frame, roller carrying frames disposed below the weight carrying frame and rockably mounted thereon said mounting including a concavely arcuate socket'in one frame anda complementary conveXly arcuate portion in the vother frame and abutting surfaces in said members concentric with said socket for retaining said members assembled, and a wearing strip inserted between said abutting sur faces. .Y Y
3. ln a soil pulverizer, a weight carrying frame, roller carrying frames disposed below the weight carrying frame and rockably mounted thereon, said mounting including a concavely arcuate socket in one frame and a complementary conveXly arcuate portion in the other frame and abutting surfaces in said members concentric with said socket for retaining said members assembled, and a wearing strip inserted between said abutting surfaces and between said socket and arcuate portion.
4. In a soil pulyerizer, a weight carrying frame, roller carrying frames disposed below the Weight carrying trame and roclrably mounted thereon, said mounting including a concavely arcuate socket in one trame and a complementary conyexly arcuate portion in the other trame and abutting surfaces in said members concentric with said soclret 'for retaining said members assembled7 wearing strips inserted between said ball and socket and between said abutting surfaces.
5. n a soil pulverizer, a weight carrying trame, roller carrying :trames disposed below the weight carrying traine and rockablyk mounted thereon, said mounting including a concavely arcuate socket in one traine and a complementary convexly arcuate portion in the other trame and abutting surfaces in said members concentric with said socket tor retaining said members assembled,and wear ing strips inserted between saidabutting snrfaces, said trames being of cast metal and said wearing strips being of steel.
In testimony whereof, I have hereunto set my hand this 5th dayot April, 1929.
