DOOR BAR-BOLT 2 Sheets-Sheet 2 Van Mcaffey Q 4 wi m0 If @63 Patented Apr. 11, 1950 UNITED STATES TENT OFFICE noon BAR-BOLT Van Mcoaaey, New York, N. Y. Application September 22, 1947, Serial No. 775,502 2 Claims. (01. 292-450) The present invention relates to new and useful improvements in sliding locking bolts for doors and for other purposes wherea bolt of this character may be used.
An important object of the invention is to provide novel means for actuating the bolt into and out of locked position from either side of a door.
A further object is to include as a part of the construction of the sliding bolt, a locking bar for securing the hinged edge of the door from becoming forced open and in which the locking bar is permanently engaged with the door casing while the slidling bolt is locked and unlocked and whereby the door is free to open without interference by the locking bar when the sliding bolt is unlocked.
Another object is to provide a device of this character of simple and practical construction, which is strong and durable, easy to install in operative position, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.
Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure l is a View in elevation showing the locking bolt andbar secured in locked position to a door.
Figure 2 is a longitudinal sectional view taken on a line 22 of Figure 1.
Figure 3 is an enlarged longitudinal sectional View taken on a line 33 of Figure 1.
Figure 4 is an enlarged fragmentary longitudinal sectional view taken on a line 44 of Figure 1.
Figure 5 is a longitudinal sectional view taken on a line 55 of Figure 4, and
Figure 6 is a vertical transverse sectional View taken on a line 6-45 of Figure 5.
Referring now to the drawings in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of my invention, the numeral 5 designates an elongated housing of rectangular shape in cross section and open at each end. Angle brackets 6 are suitably secured to the sides of the housing for attaching the housing in a horizontal position to the inner surface of a door I. The rear surface of the housing is formed with a longitudinal slot 8.
A bolt 9 is slidably mounted in one end of the housing to project therefrom, the inner end ID of the bolt being hollow and having an open rear side opposed to the slot 8, as shown in Figure 6.
A pair of pins II project rearwardly from the inner front side of the hollow end I working in vertical slots I2 in a locking plate I3 slidably positioned for vertical movement against the in nor front side of the hollow end :of the-bolt. The plate I3 is formed at its lower edge with a looking tongue It working in an opening I5,.in the bottom of the hollow end I0 to selectively-engage longitudinally'spaced apart openings I'fixand I! in the lower edge of housing 5, whenoneof the latter is alined'with opening I; The upper edge of plate I3 is'formed with a rearwardly projecting flange I8 above which is positioned: a leaf spring l9 secured at one end tothe top of the hollow end It and having itsfree end bearing against the top 'ofpthe flange to hold the tongue It in engagement in either the opening I6 or in the opening II.
The outer surface of housing 5 is formed with a longitudinal slot having vertical re-entrance slots 2! and 22 at each end and extending downwardly therefrom; A handle23 is positioned outwardly at the front of the housing Bandprovided with a stem 24 working in the-slot 20, the inner end of the stem being suitably secured to plate I3.
A conventional key operated lock 25 is secured to the outer surface of the door and includes a barrel 26 recessed in the door and a shaft 2'! extending inwardly therefrom. A combined cam and interrupted gear 28 is secured to shaft 21 and comprises a disk eccentrically secured to the shaft and having gear teeth 29 formed at one edge and a diametrically opposed flat edge 30 with cam humps 3! and 32 between the gear teeth and flat edges at each end of the teeth. The combination cam and gear 28 engages a rack bar 33 on the under side of flange I8, the rack bar being held in engagement therewith by the leaf spring In the operation of the sliding bolt 9 from the inside of the door, the handle 23 is moved longitudinally of the housing 5, which likewise moves the bolt 9 in a similar direction to engage the outer end of the bolt in a keeper 34 in the door jamb 35 to lock the door, or to retract the bolt to unlock the door. At the end of either its locking or unlocking movement the handle is moved downwardly into the vertical slots 2I or 22, as the case may be, which enters the locking tongue I4 in either the opening IE or Il to thus secure the bolt in either its locked or unlocked position. The spring I9 holds the tongue I4 downwardly against accidental raising movement.
To look or unlock the bolt 9 from outside the door, a proper key is inserted in look 25 to rotate shaft 21 and combined cam and gear 28. The initial rotation of the shaft will cause one of the cam humps 3| or 32 to raise the flange I8 and locking plate I3 to release tongue I4 and a further continued rotation of the shaft will move the gear teeth 29 into engagement with the rack bar 33 to slide the plate I3 and bolt 9 connected thereto into either its projected or retracted position in the keeper to either lock or unlock the door, in accordance with the direction of rotation of the shaft 21 and disk 29.
A locking bar 36 is mounted in the opposite end of housing 5 and is secured in outwardly adjusted position by a set screw 31. The outer end of the locking bar is engaged in a keeper 38 secured in the door casing 39 at the hinged edge of the door, the keeper 38 having an arcuate chamber 40 therein to accommodate the movement of the bar during opening and closing of the door. The locking bar 36 secures the door from being forced open at its hinged edge while permitting free swinging movement of the door when opening or closing the same.
In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.
It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.
Having described the invention, what is claimed as new is:
1. A door securer comprising a casing secured to a door, a bolt slidable in the casing, a vertically slidable locking plate carried by the bolt, interengagin locking means between the lower edge of the plate and the casing to hold the bolt in either its projected or retracted position, and means positioned at least at one side of a door for actuating the plate, said last named means including a rack bar carried by the plate and an ovate gear journaled in the door and engaging the rack bar to release or lock the plate by a raising and lowering movement thereof and to project and retract the bolt.
2. A door securer comprising a casing secured to a door, a bolt slidable in the casing, a vertically slidable locking plate carried by the bolt, interengaging locking means between the lower edge of the plate and the casing to hold th bolt in either its projected or retracted position, and means positioned at least at one side of a door for actuating the plate, said last named means including a rack bar carried by the plate, and a revoluble member having a cam initially raising the plate upon rotation of said member and gear teeth engaging the rack bar to slide the plate and the bolt horizontally upon a subsequent rotation of the member.
