FASTENERF OR THE MEETING-RAILS OF SA SHES.

SPECIFICATION forming part of Letters Patent No. 495,905, dated April 18, 1893.

Application filed SeptemberE, 1892. Serial No.'445,114=. (No model.)

To aZZ whom it may concern.-

Be it known that I, CHRIST NEUMANN, of the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Automatic Sash-Fasteners, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in sash-fasteners, and consists in the novel arrangement and combination of parts as will be more fully hereinafter described and designated in the claims.

The class of fasteners hereinafter described are especially designed for attachment to the meeting rails of the sashes, which are of the usual construction and design and the fasteners may be applied thereto without in any way disfiguring or cutting the wood.

The obj ect. of myinvention is to provide an improved lock which will fasten automatically when the lower sash is pulled down or closed and which is adapted to be unlocked by hand in the usual manner.

From the descriptions it will be seen that the objections heretofore made to sash-fasteners are overcome, and the necessity of locking the sashes by hand, is dispensed with asmy device is entirely automatic in its operation.

In the drawings: Figure 1 is a sideview of my complete invention applied to the meeting rails of ordinary sashes and shows the same in a position when locked. Fig. 2 is a top plan View of the two members of my device, applied as above stated, and showing them interlocked. Fig. 3 is a perspective view of the member which is secured to the upper sash. Fig. 4 is a side elevation of the member which is secured to the lower sash and showing the side adjacent the upper member. Fig. 5 is a top plan view of the two members when unlocked. Fig.6 is an end vertical sectional view, showing the member upon the lower sash in readiness to engage the member upon the upper sash, and showing the rails in section. Fig. 7 shows detail views of the locking lever ready for engagement, and with the other parts of the two members removed. Fig. 8 is a perspective view of the ,weighted arm, rocking shaft, interlocking le-- ver and locking arm, said parts comprising portions of the member secured to the lower sash. Fig. 9 is a sectional view taken on a line 00a: in Fig. 5. Fig. 10 is a perspective view of the locking block made use of in carrying out my invention. Fig. 11 is a sectional view on a line y y in Fig. 5. Fig. 12 is a top plan View of a modification carried out in the construction of the member applied to the lower sash and showing the same in a position when unlocked. Fig. 13 is a View similar to Fig. 12' except in that it shows the construction when locked. Fig. 14: is a side elevation of this construction with the locking block removed. Fig. 15 is a view in perspective of the locking arm and showing the Weighted lever attached thereto.

Referring to the drawings: 1 indicates the meeting rail of the lower sash 2 made use of in window construction, and which is of the usual design.

3 indicates the meeting-rail of an ordinary upper sash 4. As is well known, the lower sash 2 is adapted to slide upwardly in a plane adjacent the upper sash 4 and when thelower sash 2 is down or closed, the upper surfaces of both the meeting- rails 1 and 3 are in horizontal alignment.

I will first proceed to describe the construction of the men1ber5 which is the one secured to the meeting-rail 1 of the lower sash 2. consists of a base-plate 6 substantially rectangularin form, and having suitable perforations 7 through which screws are placed to secure it to the meeting-rail 1. The edge of the plate 6 adjacent to the meeting-rail 3 has a portion 8 cut away in order to allow the operation of certain parts hereinafter named.

For the sake of conciseness, I will refer to the side of the construction adjacent the meeting-rail 3 as the inner side and the other side from which the parts are operated by hand, as the outside. Near the outer side of the plate 6 is a rectangular shaped opening 9 which is provided for the operation of parts therein. At one end of this opening 9, and near the left-hand end of the plate 6 is an upright rectangular shaped construction 10 which has a vertical longitudinal opening 11 in the same, said opening being oblong in form and designed for the operation of parts therein. Said casing 10 extends upwardly at right angles withthe base plate 6 and in one side, the same being the side toward the opening 9, has a rectangular shaped opening 12 for purposes hereinafter set forth. Mounted in the inner side of said opening 9 and projecting upwardly from the inner edge thereof, is a bearing-block 13 one end of which adjoins the casing 10.

Immediately adjacent the inner edge of the cut-out portion 8 and extending upwardly therein at right angles with the plate 6, is a bearing block 14 similarin construction to the block 13, in that they are both provided with circularapertures 15in which the rocking shaft 16 is mounted and has its bearing. Upon the outer end of said rocking shaft 16 is keyed an eccentrically mounted locking arm 17 the extending end 18 of which projects inwardly through the opening 12 in the casing 10 and is adapted foroperation ashereinafter described. Upon the inner end of said shaft 16 is keyed a locking lever 19 and intermediate of said lever 19 and the arm 17 and secured to the shaft 16 is a small shaft 20 extending at right angles therefrom and having its free end 21 weighted to facilitate certain operations. A collar 22 preferablya part of the lever 19 projects from the inner face of said lever 19 toward the shaft 20 and serves as a gage for a horizontal movement which the shaft 16 and parts connected therewith assume in operation. The lever 19 is provided with an extending arm 23 in the same plane as its surface, and having a curvilinear slot or opening 24 immediately below and separating it from a tooth shaped projection 25, the operation of which will be hereinafter described. The locking block 26 operative in the vertical opening 11 in the casing 10 consists of a rectangularshaped block adapted to fit snugly in said opening 11 and having a handle 27 for hand operation in an elongated slot 28 in the outer wall of the casing 10. The shaft 16 is provided with a spiral groove 29 which starts at the shaft 20 and ranges up onto the top of the shaft and stops at the collar 22. The bearing block 14 is provided with a feather 30 which extends downwardly into said slot 29 thus causing the sides of said slot 29 to act as a cam in the operation of the lever 19.

Having described the parts of one member I will now set forth the construction of the member which is secured to the upper sash. It has a base plate 31 having apertures 32 through which screws are placed to secure the same to the meeting-rail 3. Upon its outer side and extending upwardly at right angles from the base plate 31 isa lug 33 which approximately occupies about half the width of the plate 31 and has upon its inner side a projection 34 which serves as a collar to prevent the rubbing against its inner surface of a locking-dog 35 which is pivotally mounted to the side thereof. The locking-dog 35 is eccentrically mounted and has its upper face 36 canted toward the lug 33 and provided with a transverse projection 37 which is of the shape of an inverted U in cross-section and which in operation is adapted to engage in a similar shaped transverse opening 38 in the under sideof the projecting arm 23 upon the lever 19. Adjacent its upper edge and upon the side of the dog 35 which is next to the lever 19 when the device is locked is a projecting ing 39 which is adapted to be engaged by the lever 19 in its descent to effect theinterlocking of said lever and the dog 35. The normal position of the dog 35 is with its elongated end 40 resting on the base-plate 31 and its opposite end 41 above the plane of its mounting and said end 41 is the same form in outline as the slot 24 in the lever 19 and 3 when the two members are locked together these two parts are interlocked.

Having fully described the construction of the parts of my invention, Iwill now proceed with its operation. To facilitate a clearer and better understanding of the descriptions, reference should be had to the illustration wherein Fig. 1 shows the two members locked together, Fig. 6 shows them in the act of being locked, and Fig. 5 shows the position of the parts as shown in Fig. 6 when looking down upon them from above. Mention has heretofore been made of the peculiar horizontal movement attained by the rockingshaft 16 and its parts connected therewith, by the use of the feather 30 engaging the slot 29 and which causes the shaft 16 to have this peculiar side motion when the shaft is turned. The normal position of the weighted end 21 of the shaft 20 is with said weight 21 upon the base plate 6 and therefore the under side of the arm 23 is in a horizontal plane, and in readiness for the engagement of the end 41 of the dog 35 when the lower sash 2 is brought lower down. When this engagement of the dog 35 in the slot commences, the lever is tilted up and consequently the shaft 16 is turned, the weight 21 lifted, and the end 18 of the arm 17 lowered and the farther down the sash is pulled, the more movement is implied to each of the above named parts, and

by reason of the feather 30 operating in the spiral groove 29, the shaft 16 and its parts move outwardly toward the other member. As the end 18 of the arm 17 goes down, the locking block 26 follows its movement until said arm 17 has assumed a position wherein the end is far enough from the outer wall of the casing 10 to allow the block 26 to fit in between said end and the wall of the casing,

thus permanently looking all of the parts, with the end 41 of the dog 35 fitting into the curvilinear opening 24 in the lever 19. When completely locked the parts have assumed a position as shown in Fig. lwith the weight 21 elevated from 0% the base-plate 6 and the locking block 26 wedged between the end 18 of the arm 17 and the opposite inner wall of the casing 10. Therefore, in order to release the engagement of the parts and to unlock the members in order that the lower sash can be raised, it is necessary to lift the block 26 by pulling up on the handle 27. When the lower sash is pushed up the parts still retain their position as when locked until the dog is entirely free from its engagement in the slot 24, when said weight 21 gravitates toward the plate 6 and all of the parts are ready for a repetition of the operation.

It is impossible for the parts to become unlocked when locked, except by the hand operation just described and no amount of tampering can cause the parts to disengage as the downward movement of the locking block 26 is stopped by the upper surface of the meeting-rail 1 and can only be lifted in the above described manner. Therefore, it is proper that I term my improved sash-fastener burglar-proof, as in manufacture it'is intended that it be constructed of some malleable metal which will preclude any danger of cracking or breaking by the jarring or forcing of the windows.

To bring about the horizontal as well as rocking movement of the shaft 16 and its parts, I could construct the shaft with a spiral feather upon its periphery to operate in a slot in the bearing block 14 in place of the construction which I have shown.

It will be noticed that the construction of the lever 19 and the dog 35 is such that they are made substantially self-balancing in order to facilitate the ready and quick operation of the parts.

In Figs. 12, 13, 14, and 15 I have shown a I modification by means of which I arrive at the same results with a simplified construction and which practically includes the same parts.

To replace the bearing blocks 13 and 14 I make use of a bearing-block 42 which is wide enough to provide a balancing bearing for the shaft mounted therein which has a groove 43 running spirally in the surface of its periphery and which is engaged by a feather 44 which projects from the block 42 into said slot 43.

Instead of having a separate weighted arm such as 21, I have provided a weighted arm 45 which has a connection with a locking arm 46. Upon the opposite end of the shaft is mounted a locking lever similar to the lever 19 and which has the same function in operation. It will be seen that this arrangement of the parts brings about the same results with a much narrower construction of base and a simplified form of construction and the operation of which in looking, is similar to the former construction.

It will be seen from the description of this modified form of construction, that the article can be manufactured at a greatly reduced cost and will present a very neat appearance upon the meeting-rail of the sash.

The member of this fastener which is secured to the meeting-rail of the upper sash is not modified in any way as I believe it to be as simple and certain in operation as would be possible.

Having fully described my invention, what I claim is 1. As an improvement in sash fasteners, a locking device consisting of. a rocking-shaft having a spiral horizontal movement, a vertical, slotted casin g adjacent to said shaft, a lever project-ing from the latter and into the casing, and a block corresponding to and working in the casing and adapted to bear upon the end of said lever, said bloek being provided with a projecting operating knob or handle; substantially as and for the purpose set forth.
