'Applicationfiled January 31, 1927. Serial No. 164,736.
This invention relates to improvements in door-guards generally, but more specifically to devices designed for use in securing the doors of a room from being opened from the outside by unauthorized persons, and has particular reference to that class of doorsecuring devices shown anddescribed in my issued Patent, No. 1,176,069, dated March 21, 1916. In this patent the adjusting means consisted of a cam lever adapted for ordinary doors. came apparent that cam members, in a device of this character, while satisfactory in a measure, failed to provide the necessary latitude of adjustment for doors of different thicknesses.
It is very desirable to provide for considerable adjustment in such devices, and I have, therefore, designed an improved and greatly simplified means for obtaining this adjustment to meet the varying requirements as above stated.
My present invention consists of butthree parts of extremely simple form, oneof which is threaded at oneend and its complementary part carries a nut loosely mounted thereon. The nut is adapted to receive the said threaded end, thus providing for a considerable range of end-Wise adjustiznent I and doorlt and does not hinder the free movement.
An important object of the present invention is to provide an improvedvdoor-securer having adjusting means adaptablefor movement from a fractional part of an inch to several inches, and for positively holding said means in adjusted position. v
Another object of my invention is to provide a .device of the class designated that is verycompa-ct for carrying in the pocket of the clothing, extremely cheap to manufacture, durable, and of exceedingly rigid construction.
Still another object of the invention pro vides that it may be readily inserted between the ed e of the door and the door-jamb of a room 3nd whether the door thereof is provided with amortise lock or not; the only requisite being that the jamb be provided with an ordinary lock-strike to receive the retaining member of the device.
In addition to the foregoing objects is the provision that when the device is in place, it holds the door firmly in the secured position and also prevents the same from rattling.
With the above and other objects in view In actual practiceit beadapted to lie as will become apparent as the description 2 proceeds, the invention consists-in certain constructions, combinations and arrange ments of parts that I shall hereinafter more fully describe and claim.
In the accompanying sheet of drawings: Figure 1 is a horizontal sectional detail plan of a door-jamb and door shown in closed position and illustrating the application of my door-securer therewith;
Figure 2 is a side elevation of the invention per se, looking in the direction of the arrow 2 in Figure 1, the nut thereof being shown partly in section;
Figure 3 1s a longitudinal mid-section of the device, the section being indicated by the line 3-3 of Figure 2; and
Figure 41 is a disassembled perspective viewshowing the various parts constituting the device. 4 v
Referring with greater particularity to the drawings, the numeral 10 designates a supporting bar constructed of thin steelof suitable gage and is provided with an offset inner end 11 adapted to engage. the usual lock-strike 12 in the door-jamb 13. bar 10 when-in position as shown in Figure 1, rests flatwise against the faceof the dooramb in the clearance space between thejamb with an elongated slot 15 extending approximately throughout two-thirds of itslength,
This
and has formed at its outer end a shank 16 having a plurality of teeth, or serrations, 17 and 18 cut in its upper and lower edges,
forming threads adapted to be engaged by an internally threaded nut 19.
The door-engaging bar 20 is provided at its inner end with a lug 21 bent at rightangles to the body thereof, said bar being flat against the supporting bar 10, as shown in Figures 1, 2 and 3, and is adapted tobe held in sliding contact therewith by means of arivet 22 which engages in the slot 15 of the bar 10. The rivet has a head 23 slidingly contacting the outside surface of said bar 10 and is adapted to hold the bars together and in slidable relation to each other.
An additional guiding means is formed in the bar- 20 and consists of a tang 24 punched from the body of the bar and adjacent the rivet 22, and is adapted to snugly extend in longitudinal movement thereon.
The outer end of the door-engaging bar 20 is provided with notched upper and lowersections 25 and 26, forming a nut-holding means adapted to retain the nut 19 in position upon the said bar and to hold it'against The nut 19 the supporting 27 are adapted to engage the upper and lower threads, or teeth, 17 and 18 thereof, in such a manner that when. the nut'is rotated in one direction the bar 20 and its lug 21 are moved outwardly relative to the member 11 of the bar 10, and when rotated in the opposite direction the lug 21 travels toward said member 11, and is thereby readily adjusted to bind against the face-edge of the door 14, as shown in Figure 1, to securely hold the door closed in its frame and thereby prevent the door from being opened from the outside of the room by unauthorized persons.
It will be apparent from the foregoing description that I have provided a much more simple form of door-securing device than that shown in my former construction, and have additionally provided a door-securing device with adjusting moans. adapt-- ing the device to operate through a considerable range of adjustment not possible of attainment with cam-actuated devices of this character, and have also attained in the pres ent construction, a device which has more positive and greater force resisting features, and one that cannot be worked loose by vibration caused by a person pounding or pushing and pulling upon the door from the outside.
From the foregoing description taken in connection with the accompanying drawings, the advantages of the construction and method of operation will be readily understood by those skilled in the art to which the invention appertains, and while I have described the principle of operation, together also embraces the shank 16 of from, and said door-engaging with the device which I now consider to be the best embodiment thereof, -I desire to have it understood that the device shown is merely illustrative and that such changes may be made when desired, as fall within the scope of the appended claims.
Having thus described my invention I claim as new and desire to secure by Letters Patent of the United States, the following:
1. door-securer, comprising a supporting bar and a door-engaging bar, said supporting bar having a lock-strike engagingmember formed at its inner end and provided with a slot extending longitudinally therebar having a door-engaging lug adapted to bear against the inside face-edgeof the door, rivet means to hold the said bars slidably together, spaced guide members carried by said doorengaging bar and being adapted to be engaged in said supporting-bar slot, the outer end. of said supporting bar having a threaded shank and the outer end of said door-engaging bar bearing nut-holding means consi sting of oppositely disposed notched edges, and said nut member being adapted to embrace said threaded shank to provide for the longitudinal adjustment of said door-engaging bar relative to said supporting bar for binding the-doorin closed position.
2. In a door-securer, a supporting bar and a door-engagingbar, a rivet and a tang car ride by said door-engaging bar, the said supporting bar being provided with a longitudinal slot for the reception of said rivet and tang forholding and guiding the bars with respectfto each other, notches providing nutholding means formed on the outer end of said door-engaging bar and threads formed upon the corresponding end of said supporting bar, and a nut loosely carried by said nut-holding means and being adapted to embrace said supporting-bar threads to cause the longitudinal adjustment of said door-engaging bar relative to said supporting to secure a door the closed posit-ion.
In testimony whereof I aflix my signature.
