AWNING.

SPECIFICATION forming part of Letters Patent 1\To'764,245, dated July 5, 1904,

Application filed January 28, 1904.` Serial No. 190,939. (No model.)

To all 'whom it may concern:

Be it known that I, RICHARD LANE, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Awnings, of which the following description, in connection with the accompanying drawings, is a specification, like numerals on the drawings representing like parts.

This invention relates to an awning and comprises a novel means for supporting the awning and Vertical operating-shaft therefor and also a novel means for locking the awning in any adjusted position.

The features wherein my invention resides will be more fully hereinafter described and then pointed out in the claims.

In the drawings, Figure 1 is an elevation of my improved awning. Fig. 2 is a section on the line fr, Fig. 1. Fig 3 is a section through the casing inclosing the crank member on the line fr, Fig. 1. Fig. 4 is a detail of the bracket. Fig. 5 is a section on line y y, Fig. 2.

3 designates the awning proper, which is rolled upon a suitable roller 4. The lower edge of the awning is connected to the usual braces 5, which are pivoted to the side of the building, as at 6. One end of the roller L is supported in any suitable bracket 7 secured to the side of the building. The other end of said roller has rigid therewith a bevel-gear 8 and is supported by a bearing member 9, which in turn is supported by a suitable bracket 10, rigidly secured to the wall. Any suitable connection between the bearing member and roller may be employed, and, as herein shown, said bearing member has the journal llprojecting therefrom and entering a recess in the end of the roller, as seen in Fig. 5. To prevent theroller 10 from being withdrawn from the pintle 11, I have made the gear-wheel 8 with the hub 68, which enters the recess in the end of said roller and through which the pintle 11 extends, and have fixed to the projecting end of said pintle a collar 69.

In assembling the parts the gear 8 is lirst slipped over the pintle and the collar 69 apn plied. Thereafter the gear-hub and pintle are inserted in the recess in the roller and said gear made fast to said roller.

The bearing member 9 has also projecting therefrom a pin or arm 12, which rests in one of a plurality of notches 13 in the bracket 10. ln this form of my invention the projection or pin 12 is in the formiof a screw secured to the bearing member; but such construction is not essential. Said bearing member besides supporting one end of the roller 4 also acts as a bearing for the upper end of the vertical actuating-shaft 14, said member being bored vertically to receive the end of the shaft, as shown in Fig. 2. Mounted on said shaft to rotate therewith is a bevel-gear 16, which meshes with and drives the bevel-gear 8 on the roller. This gear 16 is confined within the yoke portion 17 of the bearing member and rests upon the shouldercr bearing 18 thereof. tends through the gear 16 is preferably iiatsided,sothat the gear will rotate with the shaft. The object in supporting the gear 16 by the bearing member instead of by the shaft is to prevent said gear from becoming drawn out of mesh with the gear 8 in case the shaft 14 gets moved endwise.

Projecting upwardly from the bearing member 9 is an arm 21, having a laterallyprojecting portion 22, and depending from the laterally-projecting portion is a second arm 23. The bracket 1() is received between the arms 21 and 23, as seen in Fig. 5. The arms 21 22 23 constitute a safety device, for if the pin l2 becomes broken in any way said arms by dropping onto the bracket prevent the awning from falling. 1f desired, a locking screw 25 in the lfiange 22 may be used to prevent the bolt 12 from turning.

' The bracket 10 is preferably made in two parts, one, the base portion, having the notches 13 therein, and the other, the guard portion 27, which closes the upper end of the notches. One. end of this guard portion centers in a socket 28 in the brackeaand the other end has an eye 29, which iits over a screw-threaded projection 30 on the base portion.

The mechanism for` operating the actuat- The portion of the shaft which exing-shaft 14 is shown in Figs. 2 and 3. The lower end of said shaft rests in astep-bearing 31 in a stand 44, supported in a suitable casing 32, which is secured to the wall. Fast on said shaft 14 is a bevel-gear 33, which meshes with a driving bevel-gear 34, constituting part of a crank member. lSaid bevelgear 34 is carried by a shaft 35, whichv extends through and is journaled in the casing 32 and in the stand 44 and has a head 36 thereon outside of the casing, said head being slotted transversely for the reception of one end of a detachable crank 37. The head is provided with two locking-notches 38, and the crank has a spring-catch 39 thereon adapted to engage one or the other of the notches, as shown in Fig. 2. rI`he object in providing two notches 38 is to permit the crank to be inserted from either direction.

Another feature of my invention relates to the manner in which the crank member is locked against rotation when the crank is removed. The crank 37 as above stated, is detachable and is intended to be removed after the awning has been adjusted. The lock I have herein illustrated comprises a pivoted member 39', which is adapted to engage oneA of a plurality of peripheral notches 40 in a disk 41, rigid with` the gear 34, as seen in Fig. 3. As herein illustrated, the member 39l is forked at its ends, where it is pivoted to the stand 44, and its nose portion extends through the stand, the latter being cored out for this purpose, and engages the 'notches in the disk 41.

45 designates a releasing-pin mounted to slide axially of the shaft 35 and adapted at one end to engage the cam-surface 46 on the locking member, and thereby disengage said member from the disk. The pin projects through the casing, and the end thereof extends partially into the slot in the head 36 and in the path of the crank when the latter is inserted. The end of the crank is beveled, as at 47, so that when it is inserted in the slot it engages the pin 45, forces the same to the right, Figs. 2 and 3, and thereby releases the locking member from the disk 41. This operation is accomplished by the application of the crank to the crank member, and therefore when the crank has been properly applied the device is unlocked and ready for use. Upon y the removal of the crank after the awning has been adjusted the locking member will drop by gravity to its locking or operative position, and thereby automatically lock the awning in such position. If desired, a suitable The only way in which the awning can be unlocked Ais by the insertion of the crank 37, and as this will-always be in the possession of persons authorized to operate the awning it will be impossible for unauthorized persons to tamper with it.

I have also provided means for limiting the opening movement of the awning. As herein illustrated, this comprises a fixed non-rotative collar or nut 50, having a screw-threaded connection with the shaft 14 and received in an extension 51 of the bearing member, and a collar 62, fast on the shaft 14. Said nut has a pin 52 extending therefrom, which plays in a slot 53 in said extension, whereby said nut is held from turning. As the shaft 14 is turned to lower the awning the nut 50 will travel down, and when it engages the portion 54 of the extension 51 the collar 62 will be forced against said extension and the shaft n locked from further turning movement.

The crank 37 is Inade'thin and flat, as will be seen, this construction permitting me to use a comparatively flat head 36 and one Without any projections, which are liable to be in the way.

While I have described one form which my ited to the details illustrated and described, as these may be varied in many ways without departing from the invention.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-
