To all whom it may concern;

'Be it known that we, HARRY E. Nonwoon and FRANKLIN G. NIGKERSON, citizens of the United States, and residents of the borough of Manhattan, in the county of New York and State of New York, and borough of Brooklyn, in the county of Kings and State of New York, respectively, have invented certain new and useful Improvements in l0 Electrically-Operated Raising and Lowerin Mechanism for-Windows, of-which the 0 lowing is a specification.

This invention relates to apparatus for raising and lowering a window to any del5 sired position, in which position it is automatically locked and has forits object to provide simple, efficient and compact means whereby the desired raising and lowering movement of the window is 'efiectedby an electric motor. v

While the invention is not limited to any particular use it is particularly designed for raising and lowering the windows in closed automobile bodies and to this end the object is to so organize and arrange the various parts that they will permit of being concealed within the nected.

provide an organization and arrangement of parts that will-permit the withdrawal of the entire-operating mechanism for replacement or repair without removing the upholstery of the car body.

To these ends the invention consists in the combination with the window of a chain or belt drive comprising an up er and lower= sprocket and a continuous elt or chain passing around said sprockets and connected with the window and an electric motor connected with; the upper sprocket and adapted to rotate the same to raise or lower the window.-v

The invention-:further consists in the provisioniotmeans for automatically stopping the -inotorwhen-the window has reached its furthest intended closed as well as open position. 50 The invention still further consists in so mounting and organizing the operative parts that they can readily be removed without removing the upholstery on the inside of the car.

Fig. 5, to provide space for the operating parts and to permit their removal assubsequently described.

forming part of the 8 indicates a plate upon which the upperarts of the mechanism are mounted an to which'all the parts of the mechanismare secured. The said plate bears against the surface of the lock-board 6 within the well 1 and is rovi ed with aflange 9: along its upper e ge. he flange 9-seats on the upper edge of the lock-board and is suitably secured thereto as by screws 10.

The driving mechanism for raising and.

lowering the window comprises an upper sprocket 11, a lower sprocket 12 and a continuous belt or chain 13 passing over said sprockets. The drive chain carries a pin or stud 14 which works in a slot in a plate 15 depending. from and secured to the lower edge of the window 4. Upon rotation of the sprocketsthe chain, through its connection with the window by the pin 14, causes the window to be raised or lowered in a manner now well known in this art.

The upper sprocket 11 is mounted on a ball race 16 secured to the plate 8 as shown in Fig. 4, the sprocket being provided with a hollow body within which is mounted an internal gear ring 17 which rotates with and forms part of the sprocket.

18 indicates a pinionmeshing with the gear 17 and is mounted on a shaft 19 which passes through the plate 8. The shaft 19 is provided at its other end with a gear wheel 20. The gear 20 is rotated by a worm gear 21' mounted on a shaft 22 supported in a bracket 23 secured to the plate 8. The outer end of the shaft is supported in a bearing 87 provided with a ball 88 for taking the end thrust of the shaft. A casing 24 secured to the plate 8 encloses the worm 21 and gear 20 thus protecting the parts and aflording a receptacle for heavy grease or other lubricant for the parts to run in. The worm shaft 22 rejects through the casing 24 and outside t e casingis detachably coupled in any suitable manner at 25 to a shaft 26 ofa reversible type electric motor 27. The motor 27 is mounted on the plate 8 by screws28. I r 29 indicates a cross-bar connected to the plate 8 by bar 30 upon which latter bar the lower sprocket 12 is supported. The

sprocket 12 houses the usual coiled spring -for counterbalancing the weight of the win-.

dow 4 as now well understood in this art, but whlch has an additional function when employed in the apparatus herein described wherein an electric motor is used for raislng the Window as Wlll now be exp-lamed.

By the use of this assisting spring assisting the electric motor in overcoming gravity to raise thewindow the electric .load on the motor for raising and lowering may be substantially equalized. This is important inasmuch as it permits the use of a battery of com aratively small power, much less than won (1 be required if the duty were imposed on the motor of raising the whole load. Consequently a motor of very small dimensionsmay be employed-whichis important in view of the location of the motor in the wall of the well containing the operating, mechanism.

31 indicates blocks mounted on the l0W.er framework of the door and to each of which is secured a spring clip 32 (see Fig. 7). The ends of the cross-bar 29 are engaged by the spring clips 32 and which thereby detachably support the lower end of the operating mechanism. Ears 34 projecting laterally from the outer edge of each clip 32 form stops and locating devices to properly position this end of the mechanism by engaging the end edges of the cross-bar 29.

Owing to its necessary size the motor 27 protrudes through a suitable opening formed in the inner wall 35 of the door. This opening is closed and the motor casing is concealed by a cover plate 36 secured to the door in any suitable manner. Suitable means are provided for electrically controlling the action of the motor to cause it to reverse its direction of motion or in' other words to apply power. on movement in either direction under the influence of the power current therefor supplied from any suitable source. These electrical controlling means may consist of push- buttons 37 and 38 preferably mounted on this cover plate, the button 37 closing the proper circuit to cause the motor to turn in one direction by the electrical power and cause the window to be raised by the positive action of the motor, rotating in one direction being located at the top and the button 38 forming a circuit closer adapted to control or close a circuit whereby the motor will function under electric power to turn in the opposite direction and by positive action lower the window to lower the window, said latter button being preferably disposed at the lower part of the plate. Both these buttons or circuit closers are of any suitable type, there being many well known styles suit-able for this purpose, and by preference each maintains the circuit closed so long as it is pressed inward. Upon release the circuit closer automatically breaks.

To provide for the) possibility of a person keeping either one of the circuits closed, by continuing pressure on the respective button, after the window has been completely closed or completely lowered, we preferably provide means for automatically breaking the active circuit when the window reaches the limit of its travel in each direction. This may be effected in any suitable manner but by preference we provide a separate circuit breaker for the up and down travel of the window and mount both of them on the plate 8. I

The circuit breaker for stopping the mo- 39 mounted on the plate 8 and provided with tor when the window has reached its loweran adjusting screw 40 which passes loosely through holes-in the bracket 39. The lower end is, held "by a split washer 90 and a spring finger 91 bears against the knurled head 92 of thescrew to prevent rattle and turnin of the screw due to vibration. Threade on the screw 40-is a block of insulation 41 to which two terminals'of circuit wire 42 are secured. A rod 43 protruding'through the block is provided at its inner end with a plate 44 which normally completes the circuit across the terminals of the wires 42, a s ring 45 maintaining it in this position. e-outer end of the. rod 43 is provided with a head 46 which, when the window reaches its lowermost position, is engaged by a lug 47 carried by the chain 13 and by said lug the rod 43 is pushed inward and the circuit broken. This circuit remains broken until the raising button or circuit closer is actuated when the upward travel of the window allows the rod 43 to again move outward and complete the connection be-- tween the terminalof the wire 42. To allow for variations in travel of the window the time of breaking the circuit may be carefully adjusted by means of a screwdriver act-ing 'to' turn .the screw 40. The screwdriver is readily-inserted by removing the sill 3; To ermit adjustment of the position of the circuit breaker bodily to .take care of different distances between the sprockets l land 12 whereby the angle of the chain 13 on the .side of the circuit'breaker varies, a plurality of holes-85 are providedin the plate -8- for fastening the lower end of the circuit breaker bracket 39 in difierent positions, the bracketswinging about the upper fastening screw.

The circuit for the raisi'ngmovement of thewindow is automatically broken when the window has reached its up rmost position by-means of a circuit brea er indicated at 49, Figs'.3 and .4. This circuit breaker operates in a similar manner to the one previously described except that no adjustment is necessary. It isactuated by'the lug 50 which carries the pin 14 and is, as m the case of the previously -;breaker, mounted on the plate 8.

described circuit Fig. 10 it [By reference to the diagramis thought the circuitarrangement of the mechanism will be perfectly clear. The circuit for raising the windowis indicated by the wires 48 and for lowering the windowby the wires 42. 50 indicates the 'source ofsupply for the motor 27 which supply is preferably the usual storage battery carried by: the car. 51 and 52 indicate. the field windings of the motor. As will be obvious scription the window may be raised or lowered'to the desired extentby merely keeping the properbutton-pressed-until the window has reached the desired position. On releasfrom the abuts deing the pressure on the button the circuit is broken and the window comes to rest immediately and is'locked in that ositidn owing to the worm and gear drive tween the motor and the sprocket 11.

To remove the operating mechanism for repairs or replacement or to permit removal of the glass, the window is run up until it is in the uppermost position of its traveland the window is then withdrawn upward through the opening 61in the top of the door. -In cases where no opening in the top of the door is provided on where the window is in other parts of the carthan the door, the window may be removed by roviding two part guides as described in United States Patent No. 1,218,130, dated March 6th, 1917. y

After withdrawal of the window, the

screws 10 are .removed and the plate-8 carry-' ing with it the entire operating mechanism is then lifted out of the well, the lower part.

readily withdrawing from the spring cli s 32. The re-installing of'the mechanism y reversing -the operations described for removalis obvious.
