Improvements in Motors.
I, ROBERT COOKE SAYER, of 11, Clyde Road, Redland, Bristol, Civil Engineer,
do hereby declare the nature of this invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement:-
GENERAL DESCRIPTION.
The object is to use any pressure to actuate wheels or drums by fixing suitable
mechanism for their application above, and below, and on each side of the centre
of motion of double levers, and therewith give the wheels rotary motion, by the
lever acting upon teeth on the wheels, so that one end of the lever acts on one
Toward
wheel, while the other end is clear of the teeth of the other wheel.
the end of the stroke the end of the lever engaged with the teeth is diverted by
a guide, or other means, to clear the teeth of the one wheel, and the other end
of the lever is engaged with the teeth of the other wheel.
One two or more series of teeth are provided and the levers with their
mechanism are traversed from one series of teeth to another to act similarly.
When greater power is required pairs of the levers act on the teeth of a drum,
or wheels to act like a drum, so that both ends of one lever engage with the
teeth on both sides of the drum, and the ends of the other lever are disengaged
from the teeth, the pair of levers is connected by a cross lever or other means,
to transmit the power of one lever to the other. One or any number of such
pairs of levers are brought into gear with the teeth of the drum by being
traversed in or out of it.

See Figs. 1 to 5 for actuating the wheels 1 and 2 by magnets 12 to 15, they
have yokes 48, are carried by core bolts 49 on a frame 16 to slide on parts 50 of
the frame 5 and 6. Armatures 51 to 54 are secured by bolts 55 to levers 11,
they are recessed to receive poles 56, Figs. 25 to 28 and 32, and polarised by
coils 24 and 25 alternated by a switch 23 of known form centering at 59 on the
arm 60 of the frame 16 by the link 61 and able to make electric contact with the
parts 62, 63, 64 and 65, 66, 64 by the motion of the levers 11 when disengaged
from the wheels 1 and 2 and actuated by the magnets 12 to 15 to centre on the
tube 21.
The levers 11, Figs. 1 to 7; 23 and 24; have inner cylinders 9 and rods S to
engage with the teeth 20 of the wheel 1 while the other disengages from the
teeth 20 of the wheel 2 when deflected, at or near the end of the stroke of the
lever 11, at right angles to their previous motion by guides, not shown, when
the stroke of the levers 11 admit, or by magnets 17 to 20, actuating the arma-
ture 67, Fig. 4, to centre on the bolt 68, the lever 69 nut 71 and tube 70, able to
slide in the arms 72 fixed on the frame 6. 70 carries the tubes 73, Figs. 6 to, 9;
in which rods 74 that pass through slotted lips. 75 on the levers 11 are able
to slide. 74 have arms 76 and 77 slotted to receive trunnions .78. on the
rods 8 and give them motion.. One arm 76 has a hinge 79 Fig. 10, to
give vertical and horizontal motion to its arm 80 in the slot 81 of the arm. 82.
and a return 83 acts on the drum 22 in the path, Fig. 8, 84, 85, 86, 87 and gives
it rotary motion on the rod 88, the drum has electric contacts 89 and .90, when
guides divert the rods S, also 91 and 92, Figs. 11 and 12, for the magnets 17 to 20
when used, and a lever 93 centers on a rod 101, hinged to a rod 102 with, a
spring 103, carries the brushes 95 and 98 with springs 100, to meet the contacts;
receive the pressure and send it on to the magnets by 94, 96, 97 and 99...
To obtain more power, see Figs. 33 to 35 a drum 1 carried on rollers 4 .is
driven by pairs of the levers 11 the ends of each, or their rods 8, are together,
alternately, engaged with the teeth 20, while the rods S of the second lever 11
is disengaged from them, by guides, or magnets 17 to 20 actuating the shaft 21
levers 37 and links 38. The power of the disengaged lever 11 is transferred to
the engaged lever 11 by the lever 36 that centers at 136 and is attached by
suitable links 236. When guides engage and disengage the rods S with the
teeth 20, the ends of the drum 1 are drawn in to form axles to rotate in bearings
through which the shaft 21 passes and is secured and carries between the bearings.
the frame 6, 7, or a plate upon which the magnets 12 to 15 are fixed.
When other pressures are used they act on pistons in cylinders 12 to 15, and 17
to 20, or 17 only, formed as usual and work the levers 11 and other parts as if
they were magnets....
When the pressure actuates pairs of levers 11 for working the drum 1, Figs. 36
and 37, the drum 22 actuates the slides 39 and 40 of their ports by pitch wheels
and chains, 41 for the upper cylinders 12 and 13 and 42 for the lower cylinders 14
and 15 and a similar 43 actuates a tappet pin to move an inclined groove of known
form, the pressure being forwarded to the slides by rotating the handle-44. and
the actions of the magnets 17 to 20 are given by guides, or the piston.rod S inside
the lever 11 which is formed like 8 of Fig. 23, as explained below, its supply and
exhaust tap is actuated by the pitch wheel and chain 45 on the drum 22, the
pipes 46 and 47 supply pressure and exhaust.

page_text: When the rods 8 are disengaged from the teeth 20 of the wheels 1 and 2 the.
frames 16, Figs. 1 to 5, and cylinders 12 to 15 are traversed by the motions of;
the levers 11 to the teeth 30 for which, see Figs. 23 and 24, the rods 8 are formed
as pistons in cylinder 9 to which pressure is sent by pipe coils 10, Figs. 1 and 4,
and passage 137 to the front of 8 to draw them in, their backs being exhausted
by a pipe 138, pressure is then sent to a cylinder 118, Figs. 1, 4, 13 to 15 to
thrust out rods 120 and 121 links 122 turns a tube 116 and its blade 115, Figs. 16
to 20, its slot 215 clears one lever 112 and its lug 113 so as not to raise its
slide 109 but thrusts up the lever 112 that has a lug 114 and is carried by a
bolt 11 on arms 110 to thrust up by its lug 114 acting against the collar 140,
a slide 108 carried on a bolt 107 by the frame 16 on an arm 106 also an arm 123
against the power of the spring 125 held by a trunnion 126 on the bolt 107 that
rests in the socket 124 and hinges on the pawl 27 at 224, 27 centers on the
frame 16 at 105 to engage with a ratchet wheel 29 carried with its fellow 28 and
wheel 31 by a trunnion 104 on the lever 11. Pressure is forwarded by the drum 22
to the cylinders 12 to 15 actuates, to rock, the levers 11 rods 8 and the wheels 29,
28 and 31 shown dotted in their two extreme positions at Fig. 16, causing 29 to
meet the pawl 27, receive and give motion to the pinion 31 chain 32 pinion 33
and a collar 127, Fig. 17, to traverse the screw of the tube 21 taking the cylin-
ders 12 to 15 and frame 16 with them.
The lever 112 rests to slide on the blade 115, as shown dotted at Fig. 16 its
fellow being below, and when it comes opposite a slot 315 Figs. 4 and 19 in the
blade 115 at the end of the traverse the spring 125, Fig. 16, thrusts it through,
draws down the lever 123 disengages the pawl 27 from its wheel 29 and stops
it, before it stops the frame 16 meets a lug 130, Figs. 4 13 to 15, secured with
its fellow 129, Fig. 4, for the return traverse on a rod 128 inside the tube 21,
thrusts it over with its rod 128, opens a tap 133 to position 134 exhausts the
cylinder 118, its rods 120 and 135 are drawn back by a spring 139 to send the
lever 182 of the tap 133 to the end of its stroke 136, closes the tap 133 turns
the rod 116 and its blade 115 by the rod 121 and link 122, 115 in going to its
normal position meets the first lever 112, Figs. 16 to 20, thrusts it down and its
lug 113 meets the arm 140 of the ring Figs. 21 and 22, raises the slide 109 against
the spring 225 which returns it ready for the traverse back by the other pawl 26
ratchet wheel 28 and slide 109: pressure is then sent to the cylinder 9, Figs. 4,
5, 23 and 24, by the coils 10 and passage 138 to reproject the rods 8 to engage
with the teeth 30 to rotate the wheels as before.
When electricity is used as the working pressure Figs. 1 to 5, the rods 8 are
withdrawn from the teeth 20 of the wheels 1 and 2 by the known action of a
solenoid, and the levers 11 and their actuating magnets 12 to 15 are traversed
by the known means of a dynamo to rotate tubes, passed over the tube 21, that
have screw threads into which similar screw threads on the frames 16 engage and
are thereby drawn along the tube until, as before, they meet a lug 130, Figs. 4,
13 and 14, on a rod 128 within the tube 21 which actuates a switch to cut out
the current and stop the dynamo and traverse.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
Applying pressure by known means above below and on each side of the centre
of motion of double levers to give them a rocking motion for one end of the
lever, or its contained rod, to act on the teeth of a wheel connected by an axle
to a second wheel and thereby give it motion. At or near the end of the stroke
of the said levers giving them, or their rods, motion at right angles to their former
motion to disengage the previously engaged end, and engage the other end with
the teeth of the second wheel, for the reverse stroke of the said levers acting on
the second wheel to give them continuous rotation.
•
Two double levers formed and actuated similarly to the above said levers,
.

Two double levers to actuate a drum having end axles in bearings through
which is passed and fixed a spindle carrying a frame, or plate, upon which the
mechanism for driving the said levers is placed.-
Giving a drum rotation by the end of the said lever, or its contained rod, to
actuate electric contacts, and port slides, to send on the pressures.
Disengaging the ends of the said levers, or their contained rods, from the teeth
of wheels traversing the said levers with their actuating mechanism from one
series of teeth to another, reengaging them therewith and thereby similarly
giving the wheels rotation substantially as described and shown on the drawings.
