EDMOND C. WHEAT, OF COLMESNEIL, TEXAS, ASSIGNOR OF THREE-EIGHTHS
TO JULIOUS A. BEST, OF SAME PLACE.
MOTOR.
SPECIFICATION forming part of Letters Patent No. 478,774, dated July 12, 1892.
Application filed February 24, 1892. Serial No. 422,659. (No model.)To all who 7 it imany concern:
Be it known that I, EDMOND C.WHEAT, a citi-
zen of the United States, residing at Colmes-
neil, in the county of Tyler and State of Texas,
5 have invented a new and useful Motor, of
which the following is a specification.
This invention relates to that class of mo-
tors operated through the medium of weights.
The objects of my invention are to produce
io a motor of cheap and simple construction
that may be stopped and started readily,
that is automatically governed, that may be
operated continuously or without losing time
for rewinding or hoisting the weight, and the
15 power of which may be doubled or decreased
one-half, as desired, and in accordance with
the mechanism to be operated.
Other objects and advantages of the inven-
tion will be obvious from the following de-
20 scription, and the novel features thereof will
be particularly pointed out in the claims.
Referring to the drawings, Figure 1 is a
plan of a motor constructed in accordance
with my invention. Fig. 2 is a side elevation
25 of the same. Fig. 3 is an end view. Figs. 4
and 5 are detail views illustrating the pawl-
and-ratchet mechanism for locking the wind-
ing shaft and gear, respectively. Fig. 6 is a
detail vertical section showing the construe-
30 tion of the speed-governor for the main shaft.
Fig. 7 is a detail section showing the mov-
able and sliding journal-boxes and their co-
operating and adjacent parts.
Like numerals of reference indicate like
35 parts in all the figures of the drawings.
In constructing the frame-work for the mo-
tor I employ opposite pairs of end posts or
standards 1, which extend above the frame-
work proper and the mechanism, and each
40 pair is slightly inclined outwardly and con-
nected at their upper ends by transverse tie-
bars 2, upon each of which a guide or pulley
3 is mounted for rotation. These standards
or posts 1 are connected by upper and lower
45 sills, (designated as 4 and 5, respectively,) said
lower sills at their ends being connected by
transverse shafts 6 and 7, the former being
located at one end of the machine and the
latter at the opposite end. Journal-boxes 8
50o are mounted upon the opposite upper sills 4
at the centers thereof, and in said boxes atransverse main shaft 9 is journaled for ro-
tation. This shaft 9 carries at its center a
gear-wheel 10 and at opposite sides small
gears 11 and 12. One end of the shaft is ex- 55
tended beyond one of the journal-boxes 8
and has a sleeve 13 rigidly mounted thereon.
This sleeve has its outer end provided with
inclined teeth, thus constituting one member
of a clutch. As shown, adjacent to the 6o
sleeve 13 the movable sleeve or clutch mem-
ber 14 is mounted and adapted to reciprocate,
and the same has its inner end provided with
inclined teeth disposed contrarily to those of
the sleeve 13. A brake-lever 15 is pivoted, as 65
at 16, to the upper sill 4, adjacent to the
clutch just described, and is securely con-
nected beyond its pivot to the movable mem-
ber or clutch-sleeve 14, terminating at the end
of the machine in a suitable handle to be 70
grasped by the operator. It will be obvious
that when the sleeve 14 is in engagement with
the sleeve 13 rotations of the shaft 9 cannot
take place, while by swinging the brake-lever
outwardly the clutch becomes disconnected 75
and rotations of the shaft 9 are permitted.
Whether in or out of position, the lever 15 is
supported upon a suitable bracket 17, bolted
to the upper and lower sills 4 and 5 at the
side of the machine. A beveled gear, serv- 8o
ing as a speed-wheel and indicated as 18, is
mounted upon the shaft 9 near the clutch.
At this point or at one side of the same the
shaft 9 is straddled by a governor-frame 19,
the legs of the frame being bolted to the up- 85
per sill 4, upon which the frame rests. The
governor-frame is provided with a vertical
bore 20, and in the same is located a short
vertical shaft 21, carrying at its lower end
the loose friction-bearing collar 23 and bevel- 90o
pinion 22 and at its upper extremity the rig-
idly-attached screw 272, formed integral there-
with and screw-threaded at its upper portion
to receive the clamp -nut 27', which bears
against the loosely-fitting clamp-blocks 273, 95
which in turn are designed to be impinged
against the interiorly-grooved collar 26', lim-
ited in its vertical play by the top of the frame
19 and the clamp-blocks 273 and having a
central perforation, through which the screw- ioo
stem passes.
20 designates a spiral spring interposed be-
