ELECTRIC AWNING-OPERATOR.

Specification of Letters Patent.

Patented May 19, 1908.

Application filed November 23, 1906. Serial No. 344,773.

T 0 all whom it may concern:

Be it known that I, EGISTO U. GIOVANNONI, a citizen of the United States, and residentof the city of New York, in the county of New Yorkand State of New York, have invented certain new and useful Im rovements in Electric Awning-Operators, 0 which the following is a specification.

This invention relates to a.device especially adapted for raising and lowering awnings, the object being to provide a device of this nature which is simple in its construction and which shall operate automatically without attention on the part of the operator after being started either to raise or lower the awning to'the desired point at which the same is then stopped automatically. T o accomplish these results in the device herein shown to illustrate my invention '1 have provided an electric motor adapted to operate a roll by means of which the awning is raised or lowered. A switching device is rovided which is operated automatically by t 1e motor to cut out the current from the same at a redetermined point and also sets the sw tc in position to reverse the motor when the circuit is again closed.

The details of construction of the device shown in the accompanying drawings as an" illustration of one embodiment of my invention will be more fully explained hereinafter.

Inthe drawings the same partsin the several' views have been given the same referenee numbers.

Figure 1 is a side elevation of an awning operating device. Fig. 2 is a diagrammatic vlew of the o eralting circuit. Fig. 3 is an enlarged to p an view of one end of the awn ing roll an operating mechanism. Fig. 4 is a plan view of a circuit reversing switch.

At 1 is shown an awning in its unrolled or lowered osition. I

(At 2 18 indicated the usual supporting re s.

,At 3 is indicated the wallto which the awning may be attached.

At 4 isindicated a roll upon which the awning 1 may be wound. This roll is mounted u on .a shaft 5 to which is attached a gear 6 w ich is rotated by means of the worm 7 .mounted upon the shaft 8. A motor 9 which may boot the ordinary series-wound type, operates the shaft 8 in either direction.

A worm and gear 10 and 11 are operated by the shaft 8 and a'small gear 12 meshing with a larger gear 13 operates the circuit reversing device or switch. A slot 14 is provided in the gear 13 and in this slot pins such as 15 and 16 may be secured and adjusted in-such a position as to engage and operate the lever 17 at the desired points. The lever 17 operates a switch 18, which is shown in detail in Fig. 4 and indicated diagrammatically in Fig. 2 by the blades 19 and 20.

The operation of the device will be understood by referring to Fig. 1 in which the awning is shown in its lowered position and to Fig. 2 in which the operating circuits are shown. A circuit closer or switch of any desired form is indicated at 27* and'it will be seen that when the members stand in the position indicated in Fig. 2 the operating circuit is openand no current will flow to the motor. Assuming now the [witch 27 to be noved to the position indirated in dotted lines in Fig. 2 current will do v from one side 28 of a supply line through line 29, switch '27. line 30 to contact 22, through the switch blade 19 to contact21, through the lines 31 and 32 to the armature coil of the motor 9,

through the line 33 to the contact 23, through the blade 20 to the contact 26, through lines 34 to the filed winding 35 of the motor and from this through the line36 to the other side 37 of the supply line; The motor will now operate and rotate to the shaft 8 and roll 4 by means of the worm and gear 6 and 7 and the awning 1 will be wound on the roll until the worm 10 rotating the gears 11. 12

- and 1.3 causes the pin 16 to engage the 10m 17,1noving the switching blades 19 and 20 to the position indicated by the dotted lines in Fig. 2, breaking the gperating circuit and stopping the motor. he worm and gear prevent the awning from unrolling and, consequently, the same will be held in this position until the motor is again operatedin the reverse direction, as will be described.

To lower the awning from its position just described it is only necessary to move the switch, which is now in the position indicated by the dotted lines inFig. 2, to the position indicated in full lines. Current will then flow from the supply line 28 over line 29 and switch 27 to line 38 and contact 24. As the blades 19 and 20 are nowin the position indicated by the dotted lines the current will flow fromfcontact '24 over blades 19 to contact 23 and from there over line 33 through the armature of the motor 9 in the reverse direction to line 32, contact 25, blade 20, contact 26 ,and line 34 through the field coil 35 and line 36 to the supply line 37. The current in the armature of t e motor 9 thus being reversed the motor I current can only flow In one direction through will operate in thereverse direction and unthe motor when the connections are'so set.

As many changes could be made in the above construction and many apparently widely different embodiments of my invention designed without departing from the scope thereof, I intend that all matter contaihed in the above description or shown in the accompanying drawing shall be interpreted as illustrative merely of an operative embodiment of my inventlon and not in a limiting sense.

VVhat I claim is 1. An awning operator embodying an awning receiving roll, means for operating said roll including a motor operated shaft carrying a Worm, a gear meshing with said worm, a second gear carried by said first gear, a third gear meshing with said second gear and having a concentric slot formed therein, a pair 'of outwardly projecting pins adjustably engaged in said slot, a pivotally mounted oscillating switch, and an o crating arm secured at one end to said switc so as to move about the pivotal point of said switch therewith, and at its other end being for engagement with said pins.

2. An awning operator embodying an awning receiving roll, means for operating said roll including a motor operated shaft, and means to convey current to said motor, and means to reverse the direction of movement of the motor embodying a pivotally mounted insulating block, an operating arm secured to said block so as to oscillate therewith, a pair ofspaged switch blades carried by said block an projecting beyond the ends thereof, an arm rigidly secured to said block and having an upturned perforated end, and a rod having a spring encircling the same pivotally secured at one end and having its opposite end extending in said erforated upturned end.

wind the awning 1 from the roll 4 until the pin 15 engages the arm 17 and moves the switc'h'blades 19 and 20 to the position indicated in full lines in Fig. 2, thus breaking the operating circuit and setting the switch in position to again operate the motor as first i above described.

A preferred form of switch or circuit reversing device, as indicated at 18 in Fig. 1 and by the blades 19 and 20 in Fig. 2, is shown in detail in Fig. 4. In this construction blades such as 39 and 40 ma ,be mounted upon an insulating block 41 WhlGh is pivoted and to which is attached the arm 17. A contact strip 42 and contacts 43, 44, 45, 46 and 47 are mounted upon a suitable base and positioned so as to be engaged by the blades 39 and 40.. An arm 48 is secured to the block41 and is provided'with an upturned perforated end through which asses one end of a pivoted rod which is encirc ed by a spring 49 in order to produce a quick break when the blades are moved at the arm 17. This movement is caused as above described by the pins 15 and 16 engaging the arm 17 and moving the same so as tomove the blades 39 and 40, assisted by the spring 49, to the posi* tion indicated in dotted lines in Fig. 4.

The circuits are reversed in the same manner as above described in connection with Fig. 2, the blades 39 and 40 in Fig. 4 corresponding with the blades 19 and 20 in Fig. 2. It will thus be seen that by adjusting the pins 15 and 16 in the proper position to operate the reversing switch at points corresponding to the desired upper and lower positions of the awning no further attention on the part of the operator is necessary after starting the motor by moving the switch 27 ,as described. It will also be seen that when the current is automatically cut off from the motor the reversing switch is also automatically set for starting the motor in the reverse direction and it is impossible to start in the wrong direction as the connections for the circuits are set in the proper position by the reversingswitch and
