MACHINE FOR, RAMMING PAVING STONES AND THE LIKE.
Application filed September 22, 1926, Serial No. 137,019, and in Sweden June 8, 1928.
a member in the form of a sleeve 2 one end of which by a coupling mechanism is joined with a toothed wheel 3 rotating on the shaft 1. At its ends the shaft 1 is provided with threads and nuts, by the tightening of which the shaft 1 is locked in its position. The toothed wheel 3 is driven by another toothed wheel 4 fastened on the shaft 5 of a motor not shown in the drawing. The coupling mechanism between the sleeve 2 and the toothed wheel 3 is formed by a usual clutch coupling, one half 6 of which is made integral with the toothed wheel 3, while the other half 7 of the coupling is slidable but not rotatable on the rotatable sleeve 2, so that by sliding movement of the half 7 the coupling halves may be brought into or out of engagement with each other for the throwing in and out of the driving power.
The sleeve 2 is at its other end firmly connected or made in one piece with an inner oscillating drum or the like 8 surrounded by another oscillating drum 9 joined with a belt or another flexible member 10, adapted to be wound on the drum 9 when the latter 1 is rotating, in one direction, and to be wound off, when the drum 9 is rotating in opposite direction. In the lower end of said belt a ramming head (not shown) is suspended so that the ramming head is raised, when the belt is being wound onto the drum 9, and then the ramming head falls down byits own weight. The drum 9. is provided with a hub 11 which rotates on the sleeve 2. On the shaft 1 a sleeve located in the drum 8 is jammed, which sleeve is provided with two equal end cams 12 and a third intermediate cam 13 between the two end cams. Instead of the cams 12 and 13 one may of course use three cam discs firmly connected. Other guiding members may also be used. In the drum 8 of the sleeve 2 is fastened a pin 14, whereon a coupling hook 15 is swingable, said hook being provided with a shoulder 16, cooperating with the intermediate cam 13, and with two other shoulders 17, cooperating with the end cams 12. In the outer drum 9 arranged a pin, a shoulder or the like 18.
\Vhen the-sleeve 2 with the inner drum 8 fixed thereto is rotating, driven by the toothed wheels 3 and at, the coupling-hook 15 mounted in said drum 8 is swung by means of the stationary cams 12, 13 alternately into and out of contact position for the pin 18 on the outer drum 9. When the hook 15 hits the pin 18, the drum 9 is coupled to the drum 8 of the sleeve 2, so that thev drum 9 will rotate together with the drum 8 and the sleeve 2 in the direction of the arrow, Fig. 2, thereby raising the ramming head suspended-inthe belt 10 until the coupling hook, when the shoulders 17 of the same are touching the projecting parts 19 of the cams 12, is swung out of contact with the pin 18. In Fig. 2 the shoulders 17 of the hook 15 have reached the parts 19, and it will be understood that in the next moment the book 15 is swung out of contact with said pin 18 by the cam. The drum 9 being now disengaged, is forced back to its original position by means of the falling ramming head suspended in the belt 10 and the coupling hook is swung again into contact position for the pin 18 by means of the shoulder 16 co-operating with the intermediate cam 13, whereafter the course is repeated.
0n the shaft 1 a toothed wheel 19 is fastened, which engages a pivotal toothed sector 20, provided with ahandle 21. When one turns the shaft 1 by means of the toothed sector 20 after loosening the end nuts of the shaft 1, the stationary cams 12, 13 of the shaft are set, in such a way as to adjustthe moment at which the coupling hook 15 is brought sooner or later out of contact with the pin 18, for the regulation of the height of fall of the ramming head.
If desired, two or more coupling books may be 'used.
Having now particularly described and ascertained the nature of my invention, I, declare that what- I claim is:
1.111 a mechanism for actuating a ram for ramming stones, the combination with a continuously rotating member and coupling mechanism therefor, of an oscillating element about which a flexible lifting member is wound and unwound, and a radially movable coupling member turning with the continuously rotating member and being brought into and out of driving engagement with the oscillating element to effect movementthereof.
2. An actuating mechanism, as claimed in claim 1, in which the oscillating element comprises a drum having the flexible member attached thereto at one end and carrying a projection disposed in the direction of the coupling member, an inner drum forming part of the continuously rotating member and to which the radially movable coupling member is pivotally connected, and a sys tem of cams within the inner drum and disposed in the path of movement of the radially movable coupling member to effect radial movement thereof into and out of driving contact with the said projection of the oscillating drum.
3. An actuating mechanism, as claimed in claim 1, including a shaft upon which the rotating and oscillating element are mounted, and means for rotatably adjusting the shaft to regulate the timing and fall of the flexible lifting member.
4.A mechanism for actuating a ram for ramming stone and the like, a fixed shaft,
a continuously driven coupling controlled sleeve mounted on said shaft and terminating at one end in an inner drum, an oscillating drum embracing the first mentioned drum and having a hub hearing about said sleeve, aflexible belt attached to the outer periphery of the oscillating drum, 2. pin carried by the inner eriphery thereof, a coupling hook pivotal y mounted within the inner drum and projecting through an opening therein to engage the pin, and a system of cams stationary on the shaft within the inner drum and disposed to be engaged by the coupling hook during a portion of its rotation to project the hook radially to engage the said pin and turn the outer drum to wind the belt thereover and to rock the coupling hook out of engagement with the pin during the remainder of the rotary movement of the inner drum to complete a cycle, the disengagement of the parts allowing the flexible belt to unwind the oscillating drum.
In witness whereof, I have hereunto signed my name.
ERNST HJALMAR CABLSSON.
