l. MUSSELMAN STONE PULVERIZER May 23, 1959 3 Sheets-Sheet 3 ATT ORNEYS,
Patented May 23, 1950 "EUNHTED STATES a rau This invention relates to:an attachment de-fsigned for use in connection with trucks, tractors; orthe like, the primary object of the in vention being to provide a device which may be moved along over theground surface, the device J having means in the form of rotary hammers adapted to contact with rocks which are embedded in the ground surface and protrude thereabove, breaking up the rocks as the hammers rotate.
An important object of the invention is to provide an attachment of this character which may be used primarily in fields wherein limestone rocks are prevalent, so that as the stones are broken and crushed into fine particles, the lime stone will be 'distributedover the ground surf-ace supplying. fertilizer to the ground surface;
Another object of the-invention is to provide an attachment which may be readily and easily positioned or removed from a truck or tractor, means being provided for, adjusting the rotary hammer carrying member, vertically to insure the efficiencyof the device.
With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts, hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.
Referring to the drawings Figure 1 is an elevational view illustrating the front end of a truck, equipped with an attachment constructed in accordance with the invention.
Figure 2 is a plan view thereof.
Figure 3 is a sectional view taken on line 3-3 of Figure 2.
Figure 4 is a sectional view taken on line 4-4 of Figure 2.
Figure 5 is a perspective view of one of the hammers.
Referring to the drawings in detail, the front end of a truck is indicated generally by the reference character 5, the truck being provided with a power take-oft pulley 6 which is structure common to the modern truck.
The attachment forming the subject matter of the present invention, comprises a pair of bars I which are bolted or otherwise secured to the side rails 8 of the chassis of the truck.
At the forward ends of the bars l, are bearing bars 8 which are formed with forked ends into which the reduce'dend's 9 of thepivotedarms I33 extend, the arms beinglpivotally connected tothebe'aring bars 8, by meansof the pins l-l.
These arms Ill-areconnected at th'eir outer 7 ends bynieans of the cross-bar l2 which holds a pulley i aover' which the power-belt 16 operates,
the power belt also operating over the power take-off pulley- 6, so that rotary movement ofthe power take-ofi pulley 6 in thedirectionof the arrowsh'own in-Figure 1 of the drawihgswi-ll cause .the pulley l5-t'o operatein the direction of the arrowsshown adjacent to the pulley I 5.
In'order that-the-belt "I6 will remain taut, regardles'sof the adjustment of the device, an idle roller and arm 33 are provided the roller resting on the --belt l6;
:Keyed tethe -shaft M; are dis'cs I'L-eaehdiS'c being formed with a hub [B so that when the discs are positioned on the shaft, spaces will be provided between adjacent discs for the reception of the shanks I9 of the hammers 20.
These hammers are pivotally mounted on the shafts 2| which extend through aligning openings in the adjacent discs IT, as clearly shown by Figure 4 of the drawings, the shafts being provided with cotter pins 22, at the ends thereof, whereby the shafts 21 may be readily removed and replaced, should it be desired to remove and replace or repair a hammer.
The reference character 23 indicates a hood that is secured to the upper surfaces of the pivoted arms I0, and act to guard against material being crushed by the hammers, from being thrown towards the truck or tractor to which the attachment is connected.
Extending upwardly from one of the bars I, is a post 24 on the upper end of which is mounted a pulley 25 over which the chain 26 operates, the chain 26 being connected to the pivoted arm ID at one side of the attachment, by means of the hook 21. The chain 26 also operates over the pulley 28 mounted adjacent to the lower end of the post 24, the chain being connected to the piston rod 29 forming a part of the usual hydraulic lift mechanism 39' of the truck. The hydraulic lift mechanism 30, is operated in the usual and well-known manner, and is controlled by means of the lever 3|] which operates a, valve not shown disposed in the valve box 3!.
atoms If it be desired to elevate the attachment to better adapt the attachment for use in breaking up or pulverizing exceptionally high rock or stone, the lever 30 is operated to admit air to the front end of the hydraulic lift mechanism 30. The chain will now be drawn inwardly, until the desired height of the attachment has been reached.
Should it be desired to lower the attachment for better contact with a particular rock, the hydraulic lift mechainsm is operated in the opposite direction.
From the foregoing, it will be seen that due to the construction shown and described, I have provided an attachment which may be readily and easily positioned on the front end of a truck or tractor, and the hammers rotated rapidly. The truck is now operated to move the rotary hammers to a position where they will contact with rock or large stones which are protruding above the ground surface. It will, of course, be understood that it is contemplated to use the particular stone-crushing apparatus, in fields wherein large limestones protrude above the ground surface. In this case, the limestone will be crushed and pulverized and thrown over the ground surface, fertilizing the soil, At the same time, the stones will be leveled off flush with the ground surface, rendering a truck or tractor moving over the surface readily maneuverable.
Because of the shapes of the heads of the hammers, it will be obvious that when one edge of a hammer becomes dull, the hammer may be readily reversed so that a sharp edge of each hammer will be presented for contact with the stones being crushed.
It might be further stated that a suitable reduction gearing may be provided whereby the truck or tractor with which the device is used may be moved along at an exceptionally lower rate of speed to better accomplish the purpose.
What is claimed is:
A stone-pulverizing attachment for mobile power devices, comprising a pulverizer frame,
means for pivotally mounting the pulverizer' frame on the forward end of the frame of the mobile power device with which the pulverizer is used, the power device having a power take-off pulley a horizontal shaft mounted on the pulverizer frame, a pulley on one end of the shaft, a plurality of spaced discs mounted on the shaft, rods connecting the discs at points adjacent to the peripheries thereof, hammers pivotally mounted on the rods between adjacent discs, each of said hammers comprising a shank and a transversely disposed head adapted to swing beyond the peripheries of said discs contacting with the ground surface transversely disposed heads of said hammers, contacting with adjacent discs restricting pivotal movement of the hammers, a
belt operating over the power take-01f pulley and pulley on the shaft of the pulverizing attachment rotating the pulverizer hammers, a hydraulic lift mechanism mounted on the mobile power device, including a supporting chain connected with the forward end of th pulverizer frame, means for operating the chain whereby the pulverizer frame is raised or lowered, and a hood resting on the pulverizer frame encasing the major portion of the pulverizer.
