TAMPER AND LIKE IMPACT-TOOL.
Specification of Letters Patent.
- Patented Dec. 6, 1921,
Application filed April 11, 1921. Serial No. 460,557.
To all whom it may concern.
Be it known that I, (oRWILL JACKSON, a citizen of the United States, residing at Kalamazoo. Kalamazoo county, Michigan, have invented certain new and useful Improvements in Tampers and like Impact- Tools, of which the following is a specification.
This invention relates to improvements in tampers and like impact tools. I have, in the embodiment illustrated, shown my improvements as adapted by me for tie tampers although the structure illustrated with proper modification in the tool proper is adapted for use in other relations.
The main objects of this invention are:
First. to provide an improved impact tool of the class described which is highly efficient and very convenient to use.
Second, to provide an improved impact tool of the class described which enables the performance of a large amount of work with.
a little effort on the part of the user.
Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.
I accomplish the objects of my invention by the devices and means described in the following specification. clearly defined and pointed out in the claims.
A structure which is' the preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:
Figure I is a side elevation of an impact tool embodying the features of my invention.
Fig. II is a detail view mainly in central longitudinal section on a line corresponding to line 2-2 of Figs. Ill and V.
Fig. III is a detail transverse section on a line corresponding to line 3l-3 of Figs. l. ll and IV.
Fig. IV is a detail section through the tool holder on a line corresponding to line 44 of Figs. I and ll.
Fig. V is a detail transverse section on a line corresponding to line 5-4) of Fig. II.
In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.
Referring to the drawing I provide a casing like body 1 provided with bearings 2 in the ends thereof for the motor shaft 3. M0-
The invention is tor 4 is shown conventionally. On the driving or motor shaft 3 is an impact .wheel 5 having a tappet 6 set into the periphery thereof. The impact Wheel 5 is provided with a dovetailed seat 7 for the tappet 6, the tappet being slightly tapered longitudinally and retained in the seat by the Wedge 8. A tool holder 9 projectslaterally from the casing in alinement with the impact wheel. r
The tool 10, which in the structure illustrated is a tamping bar, is reciprocatingly mounted in the tool holder to project into the easing into coacting relation with or in position to receive the blows from the tappet 6. An impact bar 11 is provided for the tool 10, the tool having a collar 12 adapted to engage the impact bar. The impact bar is supported by the bolts 13 arranged through the lugs 14 on the tool holder, coiled springs 15 being seated on these lugs for supporting bolts 13. A sprin 16 is seated on the collar 12, the upper en of the spring being seated on the internal shoulder 17 in the tool holder. This spring normally holds the tool out of the path of the tappet. The collar 13 limits the upward travel of thetool so that its inner end does not bear against the impact wheel but is engaged by the. tappet when the tool is resting on the ballast or under pressure from the handle.
The handle bar 18 is resiliently connected to the casing 1 preferably by the spring members If) and 20. The spring member 19 I is S-shaped, one end of the spring being rigidly secured to the casing which is provided with the lugs 21 slotted at 22 to receive the spring attaching bolts 23'. The spring 21) is bowed and engaged with a pin 24 disposed in alinement with the shaft 3.
By thus mounting the handle the operator is relieved from shocks andvibrations of the tool, and the tool is supported so that there is a lateral as well as a longitudinal movement to its tool which is particularly desirable in the tamping of ties.
l have not illustrated the various types of tools which may be used as these would vary according to the kind of work to be performed.
llaving thus described I claim as new and ters latent is:
1. In a structure of the class described. the combination of a casing-like body member my invention, what desire to secure by Lothaving a laterally (projecting tool holder dissaid casing, a. bowed spring pivotally secured to the other end said casing, and a handle bar on the outer ends-of said springs, and a spring normally holding said tool out of the path of the tap et. l
