AVJNING-BAISING MECHANISM.

Application filed January The present invention relates to a mecha nism for raising and lowering awnings, and the invention is more particularly directed toward a construction by which the raising and lowering mechanism may be locked when the same is not in use, and the locking mechanism placed in condition to permit operation when an operating handle is inserted into proper co-operation with the raising and lowering mechanism.

Reference should be had to the L'?COI11- panying drawings forming a part of this specification, in which Fig. 1 is a front elevation of the mechanism with the cover therefor removed; Fig. 2 is a sectional elevation of the mechanism; 3 is a rear elevation of a portion of the mechanism; Fig. 4 is an elevation of an operating slide member; Fig. 5 is an elevation of a latch.

Reterring to the drawings, 1 indicates a plate which isadapted to be attached to a wall or portion of a building upon which the awning proper is mounted. This plate preferably has cast as a part thereof an upstanding wall portion 2 with which there cooperates a cover 3 that may be attached to the upstanding wall 2 in any desired manner, as by means of studs and bolts inserted through openings 4t.

The upstanding wall member is notched out at places indicated at 5, three such notched out portions being indicated, and these notched. out portions receive the arms of a spider which is indicated at 6. It will be seen that when the cover is inserted and secured in place it will hold the spider member (3 against displacen'ient.

The spider member 6 is provided with an extending hub 7 which cooperates with a recess formed in one end oi" a gear member 8, which gear member hasan extending hub t that has a l'learing partly in the upstanding wall 2, as indicated at 2", and partly in a circular opening formed in the cover indicated at 3 This hub 9 may have a squared extension 10 by which it. may be secured to a rod or similar device for "Forming an additional part of the awning mechanism which forms no part of this specification and need not further be described.

The spider also has a centrally arranged opening which is indicated at 11 which is adapted to receive an extending hub formed upon a gear 12, this gear 12 meshing with 10, 1925. Serial No. 1,546.

the gear 8. The gear also has an extending portion 13 which is adapted to extend into and co-operate with an opening 3" which is formed in the cover member There is also provided a handle 1 1- having a polygonal portion 15 which is adapted to extend into and co-operate with an opening having sides arranged in a polygonal manner, whi h opening is "formed in the gear 12 and in the drawing is indicated at 16 in Fig. 2. When the handle is inserted the portions 15 and 16 cooperate, resulting in a turning of the gear 12 which in turn will turn the gear 8, when these gears are othem ise tree to move. In connection with the construction which. has so far been described, it is desirable to have a. mechanism by which the gears may be locked against rotation, except at such time as an authorized person having the proper handle desires to operate the mechanism. This is necessary because the unauthorized persons may tamper with the mechanism, and the awning may be lowered at times when it is not desired to have it so lowered. For the purpose a detent 17 is mounted in a part 18 which forms a portion of the spider member 6. This detent is free to move up and down. to a limited extent, and at one extremity of. its movement the detent engages between adjacent teeth. oi gear 8, thus locking the gear against rotation. At the opposite end oi: its movement the detent 17 moves out of engagement with the teeth of the gear 8 and releases the gears for operating purposes.

The detent 17 has a short post 19 which extends through a slot 20 formed in the part 18. This short post 19 co-operates with a slide 21 and specifically with an inclined slot 22 which is formed in the slide 21. i

From an. inspection of Fig. 1 it will be seen that when the slide in what we may term its innermost position, the pin. 19 is at the upper end of the slot 22, and in this position the detent 17 will be elevated into engagement with the teeth of the gear 8. If the slide 21 be pulled outwardly to the dotted line position shown in Fig. 1, then the pin 19 will occupy the lower end of the slot 22, and the detent will be withdrawn to its lower position and out of engagement with the gear 8.

The mechanism which has just been described is one which is positively operated the by the hand of a user. In other words, the detent 17 is positively operated by the slide 21.

It this slide could be freely operated then of course the very purpose of locking the gears would in a measure be defeated, because unauthorized persons could manipulate the slide 21. Therefore, the construction also provides for a means to lock the slide 21 under normal conditions, but the locking means to be retracted so to permit operation of the slide 21 when a proper turning handle is inserted for the purpose of operating the gears.

For this purpose a locking pawl or latch 23 is provided which pawl extends through an opening in the spider and also into a re cessed portion of the hub 9 of the gear 8. The latch 23 is spring pressed by means of a spring2 1, which normally projects it into its locking position. When in this position the latch 23 engages with a notch 21 which is formed in the top portion of the'slide 21. \Vhen the slide is pulled inward and the latch 23 is free to move, it will occupy the notch 21 and so prevent outward movement of the slide 21. The lower end of the latch 23 is slightly cut away as indicated at 23 so that it will more readily engage in the notch 21.

In order to move the latch 23 to its inoperative position, the polygonal portion 15 of the handle is provided with an extension 25 which has a tapered nose 26. The hub of the gear 12 is also provided with an opening through which the extension 25 may pass when the handle is inserted for the purpose of turning the gears. The pointed nose 26 will engage with the latch 23 and push it upwardly, thus releasing the slide 21, thereby making it possible to operate the slide 21 forthe purpose of withdrawing the detent 17 from its engagement with the gear.

It will be obvious that as soon as the handle is withdrawn the latch 23 will be free to move, and so restore the locking mechanism to its locked position.

Having described our invention, claim 1. Awning raising mechanism com prising two meshing gears, a detent co-operating with one of the gears, a member for operating said detent, a latch for engagii'ig and locking said member, and means for operating said latch.

2. Awning raising mechanism comprising two meshing gears, a detent co-operating with one of the gears, a member for operating said detent, a latch for engaging and locking said member, a handle for turning one of-said gears, and means carried by the handle for moving said latch to inoperative position.

3. Awning raising mechanism comprising two meshing gears, a detent co-operating with one of the gears, a sliding member operatively connected with the detent for moving it to operative and inoperative position, a latch for engaging and locking said slide, and means for operating said latch to release the slide.

1. Awning raising mechanism comprising two meshing gears, a detent co-operating wit-h one of the gears, a slide for moving said detent to operative and inoperative position, a latch for engagingand locking said slide, a handle adapted to co-operate with one of thegears for turning the same, and means carried by the handle and adapted to engage with said latch when the handle is in operative position to move the latch to inoperative position thereby to release the slide.

5.
