TAMPER' Filed Feb. 25, 1929 NVENTOR 7 BY far/WW 067:?
i; ATTOR EYS Patented" Dot. 28, I 1930 coawrm. ucxson, or cnronoo, rumors amen Application filed February 28, 1929. Serial No. 342,021.
The main objects of this invention are:
First to provide a tamper which is especially desirable for use in tamplng avel, cinders and other ballast commonly own in railway parlance as light ballast.
Second, to provide a tamper which is easily manipulated and enables the performance of a large amount of work with a minimum of efiort.
Objects relating to details and economies of my invention will appear from the description to follow. The invention is defined and pointed out in the claims.
A structure which is a preferred embodiment of my invention is illustrated in th accompanying drawing, in which:
Fig. 1 is a fragmentary view of a tamper embodying the features of my mvent on, parts being shown conventionally and without special regard to relative proportions,
Fig. 2 is an'edge view of the blade-like tool, the resiliency or flexibility thereof bein indicatedby dotted lines.
Fig. 3 is a transverse section on hne 33 of Fig. 1.
Fig. 4 is a perspective view of the tool t1p or nose iece.
Referring to the drawing, the cylinder 1 is provided wlth air connections 2 and 3 at its ends. The valve mechanism is not illustrated.
The plunger 4 is reciprocated within the cylinder to deliver blows to the impact member 5 which constitutes a shank for the blade-like tool 6, this shank being longitudinally slotted to receive the tool, the tool being secured to the shank by means of the rivets 7. 1
The shank is formed of a relatively thin wide plate, being preferably upwardly ta pered, the blade being of steel or other material possessing resiliency.
At its lower end the blade is concavely curved, as best shown in Figs. 2 and 3, and it is provided with a nose or tip piece 8 of relatively heavy material, this nose piece being channeled at 9 to receive the end of the blade, the arm 10 being substantially longer than the arm 11. Rivets 13 arranged through the arm 10 and registering holes in the blade secure the tip to the blade portion of the holder. This nose or blade t1 provides an end face of substantial widt and at the same time (permits lateral vibration of the blade as in icated by dotted lines in The blade is preferabl curved as indicated which adds to its e ciency in working material under a tie. The ballast may travel down on the front side of the blade on and is effectively guided to the point where it is to be tamped.
My improved tamper is es ecially desirable for the tamping of light allast such as gravel, cinders and the like as distinguished mm what is commonly designated as heavy ballast such as crushed stone.
The tamper is light, may be easily handled and, as stated, is of large capacity; that is, it enables the performance of a large amount of work with a minimum of effort.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
1. In a tamping machine, the combination of a cylinder, a plunger within said cylinder,
a tool shank projecting into said cylinder to receive the impact of said plunger, an upwardly tapered blade-like tool of resilient material convexly curved at its lower end, and so a detachable blade tip of substantially greater thickness than the blade having its forward edge inclined in both directions from a central point.
2. In a tamping machine, the combination of a cylinder, a plunger within said cylinder,
a tool shank projecting into said cylinder to receive the impact of said plunger, and an upwardly tapered relatively wide and thin tool of resilient material longitudinally and transversely curved adjacent its lower end.
3. In a tamping machine, the combination of a cylinder, a plunger within said cylinder,
a tool shank projecting into said cylinder to receive the impact of said plunger, an upwardly tapered blade-like tool of resilient material, and a detachable blade tip of substantially greater thicknessthan the blade having its forward edge inclined in both directions from a central point.
4. In a tamping machine, the combination of a cylinder, a plunger withinthe cylinder, a tool shank projecting into the cylinder to receive the impact of said plunger, and a blade-like tool of resilient material and of substantial width and curved at its outer end, said blade being provided with a tip of substantially greaterthickness than the blade.
5. In a tampin machine, the combination of a cylinder, a p unger within the cylinder, a tool shank projecting into the cylinder to receive the impact of said plunger, and a blade-like tool of resilient material and of substantial width and longitudinally and transversely curved adjacent its outer end.
6. In a tampin machine, the combination a of a cylinder, a p unger within the cylinder,
till
a tool shank projecting into the cylinder to receive the impact of said plunger, and a blade-like tool of resilient material and of substantial width, said blade being provided with a tip of substantially greater thicknessv than the blade.
7 In a tamping machine, the combination of a cylinder and coacting plunger, an impact member operatively associated with said plunger, and a blade-like tool mounted on sald impact member, said blade being curved at its outer end and provided with a relative 1y heavy tip.
8. In a tampin machine, the combination of a cylinder and coacting plunger, an impact member operatively asseciated with said plunger, and a blade-like tool mounted on said impact member, said blade being longitudinally and transversely curved adjacent its outer end.
In witness whereof I have hereunto set my hand.
