STORM-SASH-HOLDING DEVICE.

Specification of Letters Patent.

Patented Sept. *7, 1909.

Application filed April 3, 1909. SerialNo. 487,750.

To all whom it may concern:

Be it known that'I, WILLIAM R. HALLAM, a citizen of the United States, residing at Superior, in the county'of Douglas and State of Wisconsin, have invented certain new and useful Improvements in Storm-Sash-Holding Devices, of which the following is a specification.

The present invention, While relating more particularly to means for maintaining a storm sash in diflerent positions, with respect to the frame on which it is mounted,

is not necessarily limited to such use, but

may be successfully employed in connection with relatively movable members of difierent kinds.

The primary object of the invention is to provide a simple article of manufacture, which can be readily applied by an unskilled person to the members to be held, and will effectively maintain said members either in completely closed or completelyopen position, or at different intermediate points.

The preferred embodiment of the invention is illustrated in the accompanying drawings, wherein Figure 1 is a perspective view of a portion of a storm sash and frame, showing the former in partially open position, and held by the novel means. Fig. 2 is a similar view, illustrating the sash completely open. Fig. 3 is a vertical cross sectional view through the sash and frame when the former is in closed position, and illustrating the holding means in side elevation. Fig. 4- is a vertical sectional view on the line 4t of Fig. 3. Fig. 5 is a horizontal sectional view on the line 55 of Fig. 3. Fig. 6 is a detail sectional view through the pivotal connection between the links. Fig. 7 is a face view of the inner sides of the two links at their pivotal connection, showing the interfitt-ing teeth.

Similar reference numerals designate corresponding parts in all the figures of the drawings.

In the embodiment disclosed, a bracket 8 is employed, which is secured to the frame or sill 9 of the window by screws 10 or other fasteners, and has an upstanding ear 11.

Another bracket 12 is in like manner se-' cured to the sash 13, by screws or other fasteners 14. This bracket 12 also has an outstanding car 15 and a curved lip 16, which constitutes a finger-piece.

Pivotally connected to the car 11 of the bracket 8, as shown at 16 is a link 17, and

pivotally connected at 15 to the ear 15 of the bracket 12, is another link18. The link 17 can swing between a substantially horizontal and a substantially vertical position, being stopped in the latter position by the sharp corner 19 of said link abutting against the bracketS. The links 17 and 18 are pivotally connected by a bolt 20 having a head 21 on one end and having a clamping wing nut 22 threaded on its other end. The bolt is held against turning by a pin 23 carried by the link 17, and engaging in a notch 2-it formed in one side of the head 21. A spring 25 is interposed between the link 17 and the head 21, and serves to urge the adjacent ends of the links toward each other.' This spring, as shown, is substantially in the'form of a split ring, between the ends of which passes the pin 23,'so that the spring is also held against turning by said pin (see Fig.

Surrounding'the bolt, and carried respectively bythe adjacent ends of the links 17 and 18, are interfitting teeth 26 that are disposed radially to said bolt.

The bracket 12 is provided: with an outstandingcurved spring latch 27, which may be held upon the bracket by any suitable means, as for instance, the fasteners 14. This latch has on its outer or free end portion a tooth or lug 28, which is arranged to snappingly engage over the outer edge of the link 17, when the links are located side by side, as shown in Figs. 3 and 5.

The operation of the structure is substantially as follows. When the sash is in closed condition, as illustrated in Figs. 2 and 3, the two links are disposed in substantially vertical relation, side by side, in which case, the tooth or lug 28 of the latch 27 will engage over the outer edge of the link 17, and con sequently said sash will be locked in its closed position. This locking action may be made even more secure by tightening the Wing nut 22 on the pivot bolt 20, in which case, the teeth will be positively maintained in their interfitting relation. If it is desired to open the sash, it is only necessary to loosen the nut 22, and disengage the latch from the link, whereupon by pushing outwardly the sash can swing freely, the links 17 and 18,

swinging to different angular relations.

I 25 serves to yieldingly urge saidteeth into interfitting relation. Consequently the links will remain in the different angular relations in which they may be placed, or they may be positively locked by tightening the nut 22. The outward limit of movementof the sash is determined by the length of the links, and

as shown in Fig. 2, when said links are alined, the sash of course cannot move farther. The said .llnks may be now posi- :tively locked by tightening the nut.

It Will be evident that this device is simple, 1s veffectlve and constitutes means for securely maintalning a storm sash or other device in different positions with respect :to the frame of the window.

From the foregoing, it .is thought that the construction,operation and many advantages .of the herein descrlbed invention Wlll be apparent to those skilled 1n the art, without further description, and it will be understood that varlous changesin the s1ze,.shape, proportion and minor detalls of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In connection with the .mlnor details of construction may be mentioned the feature of providing the adjoining pivotally connected ends of the links 17 and 18 with laterally deflected corner portions 8 producing opposing stop shoulders. The said opposing shoulders s of the links 17 and 18 .provide what may be termed a stop joint to prevent the appliance, when open, from jackknifing or shutting up beyond a horizontal V 1. A device for holding two relatively movable members in different relativeposr tions, comprising pivotally connected links, brackets to which the ,lin'ks'are pivoted, and holding latch carried by one bracket and detachably engaging the link that is .pivoted to the other bracket to holdthe linksagainst relative movement.

2. A device for holding two relatively movable members in difierent relative positions, comprising brackets, and means for securing the same to the members to beheld, links pivoted to the brackets, a .pivot bolt' connecting the links, a spring, and a clamp ing nut on the .pivot bolt forurging the links toward each other, inter-fitting teeth carried by the links and disposed around the pivot bolts, a spring latch secured to one bracket and having ,a tooth that engages over the link that is pivoted to the other bracket,

when the links are located side by side, and

.a handle lip formed upon the bracket carrying the latch.

In testlmony whereof I hereunto afiiX. my slgnature 1n the presence of two wltnesses.
