ELEVATOR a uwami and Augult a, 1929. semi m. 384,544.

This invention relates to elevators, passenger and freight, and especially a cableless elevator inwhich the motive power driving I the elevator car within the elevator shaft is 6 obtained from an electric motor and mechanism traveling with the car, and controlled b a human operator, the motor having suitable connections with a source of power.

The primary object of our invention isthe provision of a cableless elevator of this character providing simple but efiicient means for raising and lowering the elevator car, giving maximum simplicity of construction, maximum efliciency of operation, a mechanically balanced movement, and added safety.

Another object of our invention is the r0 vision of a cableless elevator of this c aracter wherein are means for lifting, lowering and counterpoising other than the customary cables and couuterbalances, thus simplifying the installation processes, obviating the use of crown blocks and sheaves, and various other heavy equipment peculiar to elevators of the cable type.

Another object of our invention is the r0- vision of a cableless elevator of this c aracter having the driving means mounted thereon and means mounted in the elevator shaft interengaging with the driving means propelling the elevator.

Another object of our invention is the provision of an elevator of this character comprehending an electrically driven car, the

driving mechanism bein of the gear train type, revolving co ged drive wheels engaging rack rails mounte 1n the shaft and of-special design, as hereinafter disclosed.

Another object of our invention is the provision of a cableless elevator of this character having an electrical controlling apparatus of novel design, wherein means are provided for disconnecting the electrical elements and applying the brake to the driving shaft in one operation,

Another object of our invention is the provision of a cableless elevator of this'character ,7 having operating mechanisms that require no unusual safety devices because the breakage of any part of the driving mechanisms or any of the complementary mechanisms will not release the car and ermit it to drop, but the entire equipment Wlll be held in place by the remaining mechanism used to propel the pulsion by means other than the regulation 4 cables is accomplished thus reducing opportunity for breakage, reducing quantity of equipment, movin parts, nolse to a minimum; and all suc .means havin a longer life than the standard swinging ceiles found in elevators other than our own.

Another object of our invention is the provision of a cableless elevator of this character that is balanced mechanically to provide a new passenger and freight lifting device that is to operate through a plurality of floors, and in which the applications thereof meet the requirements of insurance underwriters, ordinances governing safety devices, and which comprehend the accuracy and exactitude demanded in modern building construction.

- Another object of our invention is the provisionof a cableless elevator of this character that is less expensive to manufacture, of compact formation, readily assembled, easily installed, easily applicable in the architectural and building art, and of efficient and durable construction and of minimum expense in maintenance.

Another object of our invention is the provision of a cableless elevator of this characas the invention is hereinafter disclosed, our

of the elevator shaft, showing the car with motor and driving mechanisms secured to the elevator car the car;

Figure 3 is a bottom plan view of the driv- 7 ing mechanisms secured to the bottom of eleanism ;and

vator car;

Figure 4 is a vertical sectional view on the line 4-4 of Figure 3, omitting the gear mech- Figure 5 is an enlarged top plan view of the brake mechanism.

- Referring now specifically to Fig. 1, elevator motor is shown underslung on elevator sisting of cog wheels A,

car 11 by lug bolts 12.

Armature shaft 13 protruding from the cage of electric motor 10 penetrates stanchion plate 14 and by means of-spur gear wheel 15 generates the movement of ear train 16 conand C intermeshed with spur wheels 17 and 18.

Gear train 16 is held in place by stanchion plates 14 and 20, stanchion plates 14 and 20 are held together by binder pins 21, 22, 23 and 24 (see Fig. 2). A

Drive shaft 26 disposed centrally through cog wheel C of gear train 16, and rigidly attached thereto, connects cog wheels 26 intermeshing with rack rails 27 which are disposed parallelly and perpendicularly in the elevator shaft.

Drive shaft 26 is held in place by brackets 28 and 29 and stanchion plates 14 and 20, all of which are attached tofioor 30 of elevator car 11.

- Brake drum 31 (see Fig. 2) is attached to armature shaft 13 and revolves therewith.

Brake straps 32 are suspended from diamond shaped lever 33 which is (gsee Fig. 5E) attached and fulcrume by lever olt 34 attached to floor 30 of elevator car 11.

Referring now specifically to Fig. 4 in disclosure of the operative functions controlling independently the braking of the elevator car 11. -Operators controller'35 (see also Fig. 1) is fulcrumed by pin 36 protruding through hatchway 37 (see Fig. 3) in floor 30 of elevator car 11 and is hingedly connected to gure 2 1s a side elevational view of our. improved drlving mechanism for operating reach rod 38 by pin 39. Reach rod 38 is rigidly attached to lever 40 and suspfnded from bracket 41. Lever 40 is hinge y attached to reach rod 42 connecting with diamond shaped lever 33 controlling brake straps 32, as shown.

Referring now specifically to Fig. 3, is shown the single operative control of braking and powering the elevator car 11.

Connected to lever 41 (see also Fig. 4) is drive rod 43 rigidly engaging lever 40 to which is hingedly attached reach rod 42, as described.

Rigidly attached to reach rod'43 is lever 44 hingedly engaging reach rod 45 which in turn hingedly engages current contactor 46.

It is shown that when power is applied the brakes are simultaneously released; and, conversely, when power is cut off the brakes are simultaneously applied by the single operations of operators controller 35.

Casing 47 protecting gear train 16 from dirt and other foreign matter is shown. Referring again specifically to Fig. 1, Porters t pe loaded governor 48 mounted on the top 0 elevator car 11 is shown connectedto cog drive wheel 50 b drive rod 49. Cog drive wheel 50 intermes es with rack rail 27. Governor stem 51 is revolved from bevel gears connected in jacket 52 at the base of Porters type loaded governor 48.

Bracket 53 supports lever 54 connected to bell cranks connector 55. Hingedly connected to lever 54 is reach rod 56 joined to operators controller 35, not shown in the draw- .Porters type loaded overnor 48 works by the centrifugal action of balls 57 attached to bell cranks'58 which fly away from or towards their axis of revolution accordinglas their speed is increased or diminished, t us lifting or lowering bell cranks connector 55 and transmitting motion to lever 54 and complementary attachments as shown and described.

' From the foregoing it will be seen that our invention attains all its objects and conceived intentions and designed purposes in a highly elficient and satisfactory manner. It is obvious that our invention is particularly well adapted for use in buildm s, or wherever elevators may be particular y or generally required, by reason of the facility and convenience with which it may be used, assembled and operated. The construction, arrangement and relationship of the various parts may be varied in numerous particulars and within the equivalent limits without departure from the nature and principle Lemma of the invention. We do not restrict ourselves unessentially, but
