COMBINATION GRAVITY LA'roH AND LOCK FOR noons, wnvnows, AND GATES.

A plication filed January 10, 1924. Serial No. 685,452.

To all whom it may concern:

Be it known that I, ORLANDO M. FEE, a citizen of the United States, residing at Lamanda Park, in the county of Los Angeles and State of California, have invented Combination Gravity Latches and Looks for Doors, lVindows, and Gates; 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 anduse the The invention has relation to fastening means and has for its primary object to provide a device adapted for general use either as a holder or lock whereby to secure a part such as a window sash in the required adjusted position or to lock the parts, such as a door, sash, gate or the like when closed.

Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.

While the drawings illustrate an embodi ment of the invention it is to be understood that in adapting the sameto meet different conditions and requirements, various changes in the form, proportion andminor details of construction may be resorted to provided they fall within the spirit and scope of the invention.

determined position.

Figure 12 is a sectional view taken on the horizontal plane indicated by the line 1212 of Figure 9.

Corresponding and like parts are referred to in the following description and designated in the several views-of the drawings by like reference characters. 1

In its simplest form, the fastener comprises anelongated block 1 provided with a longitudinal slot 2 and end openings for receiving screws or other fastening means whereby to attach the device to the cooperating part. An L-shaped latch 3 is pivoted by one of its members to the block 1, the other member being weighted and norn'ially occupying a position at one side of the block and holding an end of the pivoted member projected so as to engage the part to he held in a predetermined position. In practice the block 1 is let into the part to which it is fitted, as shown most clearly in Figures 6 and 7. hen applied to a window, it is preferred to applya number of the fastenings to the window frame or sash as found most convenient. The numeral 4 designates the sashof a window and 5 the frame or.

casing. Keepers 6 are shown applied to an upright of the frame to coact with the projecting end of the latch 3 applied to a side stile of the sash 4. By providinga number ofv keepers 6, as indicated most clearly in Figure 1, the sash may be held at any pre- A flexible connection may be attached to the weighted mel'nber of the latch and serves as convenient means for moving the same from the position shown by fulllines in Figure 6 to the position shown by dottedv lines inv the same figure. As indicated in Figure 6, a channel 8 may be formed in a stile of the sash to receive the projecting end of the latch 3, thereby admitting of the sash having a limited movement for ventilation, but preventing anyone entering the window from the outside.

The latch 3 may be held in either extreme adjusted position by means of a dog 9 which is similar in formation to the latch 3 and which is pivoted by one.of its members, the other member beingweighted to normally hold the dog in a given position. The dog 9 is disposed in a plane at a right angle to the plane of the latch 3 and its pivoted member is adapted to engage the weighted member of the latch whereby to hold the latter in either position shown by the full and dotted lines in Figure 2. The latch 3 is held in locking engagement by means of the dog 9 engaging the outer edge of the weightec member of the latch, as shown most clearly in Figures 2 and at. when thelatch 3 is moved so as to withdraw the projecting end of the pivoted member, it is retained in such position by the dog 9 engaging the inner edge of its weighted member, as indicated most clearly by the dotted lines in Figure 2. In this position of the parts, the sash or other part may be moved freely in either direction. The dog 9 is adapted to be c.on veniently operated by means of a flexible connection 7, such as a cord or chain.

In Figures 9, 10 and 11, the fastening is shown applied to a door. The numeral 11 designates the door jamb and 12 the door. The fastening is shown applied to the jamb 11 and coacts with a keeper 13 applied to the door. The latch is adapted to be held in withdrawn position by means of a pin 14; which is introduced into an opening formed in the jamb 11, the projecting endenga'ging under the weighted member of the latch. When the pin is withdrawn the latch assumes a normal position and engages the keeper 13., thereby locking the door. In this case, the flexible connection 1% is attached to a weight 16 which is suspended upon a pin 17. A. yoke 18 is slipped upon the pin 17 in the rear of the weight 16 and a bail 19 attached to the ends of the yoke 18 is connected at one end to the bail and at its 0pposite end to the door frame to prevent loss or misplacement of the parts. A flexible connection 21, such as a cord, is attached at one end to the bail 19 and its opposite end is made fast to a timecontrolled pulley 22 upon which it is adapted to be wound whereby to disengage the weight 16 from. the pin 17, the falling of the weight operating tov withdraw the latch 3 from locking engage ment with the door which, being released, may be opened from the outside. The pulley 22 may be controlled by any preferred type of trap movement 23 which is adapted to be set so as to release the pulley operating mechanism to effect rotation of the pulley to wind the cord 21 thereon and effect disengagement of the weight 16 from the supporting pin 17. It will thus be understood that prior to leaving an abode the pin 14: may be placed in position to hold the latch S. in withdrawn position so that the door 1:2 may be closed, after which the pin 14 is withdrawn thereby permitting the latch 3 to assume a locking position to secure the door from being opened from the outside. The weight 16 having been suspended from the pin 17 and the connection 21 unwound from the pulley and the clocl-r movement 23 set to release the pulley oper ating mechanism at the required time, it will be understood that at the time set, the pillley operating mechanism is tripped and the pulley 22 rotated to wind the connection 21 thereon with the result that the weight 16 is disengaged from its supporting pin 17 and falling withdraws the latch 3 from looking engagement with the door which may be opened from the outside, as will be readily understood. This time lock can also be operated by an alarm clock, with a lever arrangement for removing the weight from the pin, with the same results following as. above stated, but the lever arrangement is more dc sir-able, as it adds additional power, and is simple and easy to construct.

lVhat is claimed is:

A fastening comprising a longitudinally ORLANDO M. FEE.
