Application med .Tunev4 1o,
Thrill whom it may concern: i'
Be it known that I, NATHANIEL C. STUDY,
acitizen of the United States, residing at Kalamazoo, Michigan, have invented certain. new and useful 'Improvements in Tamping- Machines, of which the following is a'speci.- ication. v
This invention relates to improvements'in tamping machines.:
My improvements are specially designed by me for embodiment in tie tamping machines, and -I have illustrated and described samekherein as'I have embodied in such a machine Certain features of myimprovements are,' however,'desirable 4for use in other relations. 1` c l The main objects of this invention are: 1 .First, to provide an improved electrically driven tamping machine which is very efficient and at the same time very light Ain weight, simple,feconomical' and durable in `Second, to provide animproved'tamping machine which is conveniently handled by the workman and with comparatively little effort, the same -being easily manipulated in the various relations and positions in which tampers-are required in railway construction and the like. i p
Further objects, vand objects relating to structural detail, will vdefinitely appear from the detailed, description to follow.
I accomplish the objects of my invention by the devices and means described in the tamping machine.
following specification. This invention is clearly defined-and pointed out in the claims.v I
' A structure which is a preferred embodiment of my inventionis clearly illustrated vin the accompanying drawing forming a.
part of this specication', in which:
Figure I is a front view ofmy improved'.
Fig. II is a view partially in tudnal'secton on line 2 2' of Fig. I, and partially in side elevation.
' Fig. III' is a detail view partially in cross'section on a line corresponding to line 3-3 of Fig. II. l
Fig. IV. isa detail View partially in lon i` tudinal section, corresponding vto Fig. I, with the impact member and the tamping bar at the limits of their out strokes Fig. V is a detail view partially 1n section on a line corresponding to line 5.-'-5 of` Specication of Letters 1atent.

ciprocates,`and a cap-like retaining member 4 removably securedlto the member 3 by a bayonetA joint, the member 3 being provided with pins 5 and the member 4 with bayonet slots 6.;
The tamping bar has a stop collar 7, the opening in the lower end of member 4 being .The retaining plate 9 has a slot 10 therein so that it may be slipped'upon thetamping bar -below the collar, and seated in retaining-member as shown.
Within `the body member is an electro- Fig. II showing the arrangement of the conf such as to permit the passage of this collar.
magnet or solenoidpll, for actuating the reciprocating impact member 12, the tamping bar being arranged to receive the blows of this impact member. The strokes of the impact member and the tamping member are such that theyv are` separated when both are at the limit'of their strokes (see FigIV). The impact' member is returned by the upper end ofthe solenoid and engages a The circuit is controlled by a pair of fixed contacts 15, one of which is connected to the 4spring 13. The spring 13 is seated on the collar 14 on the upper end of the impact member.
solenoid by the wire 16, and the other. by i wire 19 to `a switch designated generally by the numeral 17 mounted at the end of handle 18. The other lead of the solenoid is indicated at 20. 'The circuit wire leading to the switch 17 is indicated at 21. member 12 carries a contact member 22, it
being yieldingly supported by the coiled spring 24. The contact member 22 has a rounded head 25 which engages the contact members 15 when the impact member is in its initial position, thereby closing the circuit to the solenoid and thereby actuating .the impact member. The spring 24 re- The impact tains contact member 22 in :its circuit closving position during a portion of the stroke of the impact member, thereby insuring its complete actuation at each stroke. c
To prevent the adhering of the impact member to lthe tamping bar, an insulating "disk 26 is arranged in the impact face of lthe tampingbar, thus insuringlthe prompt separating of these parts.
The handle 18, which for convenience is 'grip 27 at its outer end.V I
I provide a-supplementaryor auxiliary trated. The handle 18 is provided with a handley 28 which isa-dapted to be 'mounted handle, said link-like handle member being on an ear 29 on the 'front side of the handle y 18, or on the link-like handle mem'berv 30' which is mounted on an ear 3l at .the lower end of the body. The link-like handle inember 8O isv adapted to be engaged by pin 32 by which the auxiliary handle 28 is mounted on the ear 29 so that it is supported out of the way of the operator.
By providing the handles as illustrated, the machine may be handled and adjusted -to meet the particular requirements of the work, or the convenience of the operator entailing the least effort on the part of the operator.` f
My improved tamping machine is eilicient, is comparatively light in weight, and is economical and durable in construction.
I have illustrated and described my improvements as I have embodied them in a structure which is very satisfactory. I havenot 'attempted to Aillustrate other embodimen-tsor adaptations, as Iv believe the disclosure made will enable those skilled in the art lto which my invention relates to embody or `adapt the same, as may b e desired.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent,'is-:
