Y $11 Schedule referred to 1n these Letters latant and malrlng part o! tua am.
To all whom it mmf. concern:
Be it known that ,1, GEORGE F. GREEN, of Kalamanoo, in the county of Kalamazoo, and State of Michigan, have invented certain new and useful Improvements iu Automatic Tooth-Pluggers; and I do hereby declare that the following isa full, clear, and exact description thereof, reference being had the annexed drawings, making a part of this specilication, in which- Figure 1 isadetdched view of the reversing-valve.
Figure 2 is adetnched view of the parts that operate the reversingwa ive.
Figure 3 is a 60.1151@ beaded valve. which admitsthe 'an' alternately'to ertner'end ofthe cylinder.
Figure 4 is a point-holder, receiving the point at one end, and the blows from the piston-rod at the other.
Figure 5 is a sectional view, cutting the cylinder and case through the centre. l
Figure 6 is a side View, showing the slide and forked lever, which operates the reversing-valve.
Similar letters of reference indicate corresponding parts in the several figures.
The nature of my invention consists in the novel style of valves used, andA in the novel manner of operating them directly from the piston-head,.thus obviat-ing the employment of a cross-head in connection with thelpistonrod. Also, in the swivel elbow-joint, connecting side-pipe to the bellows.
The object of the invention is to obtain a. valve that will be caused to shift and carried by the dead-point, by the pressure of air, without the aid of springs or look.
To enable others skilled in the art to understand and construct my invention, I will proceed `to describe it.
A represents the cylinder of an engine, to one end of whichl the case, J, is firmly attached.
In the out end ofthe case J, the point-holder H, (see figs. 4 and 5,) is fitted, the object of which will presently be explained.
The oase J is jointed at N, so as to allow 4the out end, or' point to be-revolved, independent of the en gine, at the will ofthe operator.
The slide L is'itted in ways, between -and on the I outside of the side-pipe O and cylinder A.
To one end of the slide L, which is bent downward,
and at right angles, there is made fast a rod, O, running parallel with the slide, (see fig. 2,) which plays through a hole in the head of cylinder A, and also through the pistol -head B, as shown in dotted lines in o. 5.
Tile rod o is pwided with shoulders P P, at either end, and as the pision-head is drivenl forward, it comes in contact with one of the shoulders P, on rod O, thus causing the slide I. to move, and bring the stud Q in .contact with the opposite side of the forked lever K,
which is made fast to the end of shaft R, on reversingyalve E, thus thrling the current of air onthe opposite side ofthe'partftion S, 1u 'side-pipe C.
The air acting on the double-headed valve T as a piston, itis driven by the ports V V, thus allowing the air tofpfass in at one end, and exhaust at the other.
The double-headed valve-rod T plays through a pipe, U, placed longitudinally, in the centre of side pipe C, and made fast to the partition S.
There is a joint inthe pipe M, just below the elbow Ewhich allows the instrument to be held at any angle, without kinking the pipe.
As the piston-'rod W is driven forward in the case J, it comes in contact'with the end of point-holder H.
The point-holder H is fitted, in the out end of the case J, with a slot and feather, the object of which is to cause the point to revolve withthe case,- and also to allow it a longitudinal movement.
Having thus 'described the nature and object of my invention,
What I claim as new, and desire'to secure by Letters Patent, is
1. The reversing-valve E, arranged and operated as described, in combination with the independent doubleheaded valve T, and partition S, substantially as and for the purpose set forth.
2. The point-holder H and jointed case J, in combination with the cylinder A, for the purpose described.
3. The swivel-elbow pipe F, for the purpose set forth.-
JAMns F. GORDON, PHILANDER ANDERSON.
