To all whom it may concern:

Be it known that I, NATHANIEL ROE, a citizen of the United States, residing at Patchogue, in the county of Suffolk and State of New York, have invented certain new and useful Improvements in Means for Operating Roller-Awnings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

For safely and securely operating awnings I have produced a new combination of hand operated devices whereby a suspended opera-ting-shaft by which the awning is rolled and unrolled, is adapted to be pulled out and held atits lower end from the wall at a given an le to allow the erating shaft to be rotag te to cause the awnmg to be either rolled or unrolled in connection with a novel locking means for the operating-shaft, whereby it is caused to maintain a locked relation to the awning roller to prevent its rotation in either direction except when the operatin shaft is in the position to be rotated to roll and to unroll the awning. In this locking means a s 'lable sleeve on the operating-shaft cooperatvo with a slotted arm ivotally mounted at one end on the wall ant adapted to swing in and out therefrom with the operatingshaft toallow the latter to be rotated, to be locked, and to be unlocked.

The accom )anying drawings illustrate my invention and in which;-

Figure 1 shows a front elevation of a roller awnin with my improved operating means applied thereto the awning being in its roiled position. Fig. 2 is aside view of the same the awning being in its unrollcd locked position. Fig. 3 shows a like view in which the suspendec operating-shaft is seen swung out at its lower end from the wall in the position in which it is held by the swing arm to allow it to be rotated to roll or to unroll the awning. Fig. 4 shows in side view enlarged the lower portion of the operating shaft, the swing-arm, and the slidable-sleeve which cooperates as the locking means for the operating shaft, the parts being in the normal locked positions seen in Fig. 2. Fig. 5 shows in detail in side view the upper end of the swing-arm and its slidable sleeve in the position of the latter when it is desired to unlock the operating shaft to allow it to be rotated. Fig. 6 is an enlarged detail view showing the operating-shaft and the swim arm in the 7 positions they occupy when uu ocked and swung out and the shaft free to be rotated in the operation of rolling and matching the awning. Fig. 7 is a like detail view showing 0 the same parts in the positions they occupy when the operating-shaft is passing from its unlocked position with the outer projection 12, of the swing-arm to a locked position with the dog 18 on saidswing-arm. Fig. 8 is a 5 horizontal section on the line 88 of Fig. 4,; showing the inner lock of the swing-arm for the shaft. Fig. 9 is a horizontal sectiorhon the line 9E) of Fig. 5 showing the on

er locks

12 and 18 of the swing-arm. Fig. 0 shows a detail sectional view of the roller bearing swing socket. f- The awning is carried by a roller mounted at the top of the window casing in the usual way and has the usual frame-supports 11 pivoted to the wall. On the shaft 2 of the roller at one end 1 thereof, is fitted a socket-bearing 3, so as to swing freely on the shaft and at one side of this socket-bearing the roller shaft has a bevel-gear 4, which engages with a bevelgear 5, fixed on the suspended end of the operating-shaft 6, the upper end of which passes through, is suspended by and is fitted to rotate in the swing-socket as in Fig. 10. At its lower portion for a distance of about eight inches in length the operating shaft has a groove 7, diametrically on each side; and

fixed to the wall at the lower end of the opcrating-shaft is a bracket 8, preferably of bifurcated ears between which is mounted to swing on a strong pivot J, an arm 10, having a length about equal to that of the shaftgrooves and a slot 11, which terminates near each end of the arm. On its pivot the arm is free to swing toward and from the operatingshaft, and at each end thearni has a projection the outer one of which 12, is adapted to engage the groove in the operating-shaft to prevent its rotation; while the inner projection 13, is adapted to extend through an opening in the operating-shaft to receive a lock 14. to fasten the operating-shaft to the swing-arm as shown in Figs. 4 and S. In their normal positions in which the operatlug-shaft is locked by the

arm projections

12 and 13 the shaft is in parallel relation with the swing-arm and in this relation they are coupled together by a sleeve 15, slidably fitted upon the. operating-slmft and has a 110.

yoke 16, which is con )led by a bolt 17, with the swing-arm, the bolt for this purpose passing throu h and movable in the arm-slot. This coupling of the sleeve with the slotted arm allows a vertical movement of the former on the shaft, which is limited by the coupling-bolt l7, striking the outer end of theslot in the swing-arm, as in Fig.5, and it is at this relation of the operating shaft with the swing-arm that the former is free to be swung out from the locking projections of the swingarm to allow the shaft to be rotated to roll and to unroll the awning as in Figs. 3, 6 and 7. This outward swing of the operatingshaft and its rotation is allowed by its socket connection with the swing-bearing of the roller-shaft; while the release of the operating-shaft from the projection at the oti-ter end of the swing-arm is effected by the s ing of the sleeve over and against the end of the said arm, in the arc of a circle described f1 om the coupling bolt 17 as in Figs. 3 and 6. In describing this are the sleeve will rest against the upper end of the arm and hold the shaft in the position seen in Fig. 3. the yoke and of the operating-shaft. and the outward and downward swing movement of the slotted arm, causes the outer projection 12, on the latter to be'withdrawn from the groove of the shaft, and, if the awning should be in its raised position it would be free to fall and by its roller-gear connection with the operating-shaft, cause it to rotate rapidly and the awning wall supporting arms to fall with heavy thrusts endangering the awning connections with the roller. To avoid these destructive contingencies I provide a supplemental lock the function of which is to engage the groove of the operating shaft and cause it to be looked as the projection 12, is being withdrawn from its locking engagement with said groove. lock is effected by a dog 18, pivoted in a groove at that side of the slotted-arm opposite the projection 12, and extending above the end of said arm into and through a slot 19, in the sleeve and into engagement with the groove in the operating-shaft as shown in Figs. 4 and 9. A spring 20, at the pivoted end of the dog serves to keep it in locking position until the operator is ready to unroll or to roll the awning, when he pres es the end of the dog to cause its locking end to be withdrawn from the groove in the operatingshaf t as in Fig. 6.

From the foregoing construction it will be noted that three separate and distinct locks are )rovided for the operating-shaft and that the latter is always locked exec t when the awning is being rolled or unrolled so that the awning can not fall from any inadvertence of the operator.

I prefer to make the operating shaft in two sections in which the upper section will be fastened by telescoping it into the lower see- This swing; of

This supplemental tion and the latter terminates in a square to receive the crank 21, for rotatirw the operating shaft as in Fig. 3. 3

While the yoke-sleeve by its slot 19 is free to slide over the locking )ro'ection 12, it not only serves as the means i'or locking the shaft to the inner end of the slotted-arm so that neither can be separated but the yoke-sleeve serves as the. means by which the shaft and the arm are free to be swung apart and in such swing function the sleeve by its yoke connection will cause one lock 12, to be released from the operating-shaft and simultaneously cause the supplemental lock 18, to be engaged with the said shaft whereby the latter may be held until the operator is ready to rotate it when, by his hand, he releases the sup )lemental lock as in Fi 6. The limiting of the outer movement of the yoke-sleeve by the outer end of the arm-slotas in Fig. 5, is the key to the relation of the parts whereby the swing function of theshaft and of the slotted-arm may be effected for' unlocking the shaft; while the inner end of the arm-slot limits the inward movement of the yoked-sleeve as in Fig. 4 and in this posi' tion the sha'f t is locked to the wall-bracket as in Fig. 4; whilethe shaft is locked to the arm projection 13, by a look.

Looking at Fig. 3 it will be seen that it is the downward swing movement of the locking-arm and the outward swing movement.

of the operating-shaft that causes the locking projection 12, to be withdrawn from the groove in the shaft to allow the operator to rotate the shaft as in Fig. 6; while he holds the pivoted dog 18, out oflockingengagement with the groove in the shaft and the awning thus rolled or u'nrolled. The dog is then released and again enga es the shaft while it is being moved into locking engagement with the arm projections and fastened by the lock.

An important feature of my invention is the construction by which the operat ng shaft is suspended in its swin socket and allowed to be swung out with its locking arm before the awning can be operated whereby the projecting shaft is adapted to have both a swing and a rotating movement in the operation of rolling and unrolling the awning.

The device can be substituted for the gearbox now in use for operating awnings by euttingoll' thelowcr part of the shaft and coupling it as shown with the grooved section at 22 in Fig. 4.

I have described and shown the operatingshaft as having a groove on eaclrside, but obviously a groove on one side only is neces sary, the two grooves merely serving to facilitate the engagement o the snaft with the locking projections in op\.'.'ating the shaft.

Looking at Fig. 2 it will be noted that in the normal position of the operating shaft in relation to its connection with the wall, would render it too inconvenient to operate the shaft by a crank applied at its lower end on account of the proxnnity of the shaft to the wall. and it is for this reason that I have designed the suspended swing-shaft and the pivot-2d swing-arm connection of the shaft with the wall, whereby the operating-shaft may be swung out from the wall to allow a crank to be applied to its lower end to rotate it as in Fig. 3; and I have utilized this swingarm connection as the means of'locking the operating shaft when it is not used to operate the roller. It will also be noted that the mounting of the socket-bearing 3, on the end of the roller-shaft and a bracket-stud 23, allows the said bearing to have an oscillating movement to accommodate the swing movement of the operating-shaf t and this without interfering with the roller-shaft.

I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.
