G. HENSLE. BURGLAB. PROOF ATTACHMENT FOR DOORS.
APPLICATION FILED JULY 18, 1911.
Patented Nov. 28, 1911.
UNITED STATES FATEET GEORGE HENSLE, OF NEJV- YORK, N. Y.
BURGLAR-PROOF ATTACHMENT FOR DUCKS.
Specification of Letters Patent.
1911. .Serial llo. 639,171.
States of America, have invented certain new and useful Improvements in Burglar-Proof Door Attachments, of which the following is a specification.
My invention relates to burglar-p vide a simple and inexpensive device which may be readily attached to doors for effectively preventing opening a door by jimone of its ends, against which the door mying.
I will describe my invention in the following specification and point out the novel features thereof in the appended claim.
Referring to the .'drawings, Figure 1 is a sectional plan view of a door casing and a swinging door with a' spring latch and with my novel attachment shown thereon. Fig. 2 is a similar view of the end portion of the door and a part of its casing with a modified form of .my invention shown in conjunction therewith. Another modification of the inventionis illustrated in a similar view in Fig. 3. Fig. 4 is a perspective view of the two parts of my attachment, and in Fig. 5 a still further modification is illustrated.
Like characters of reference designate cor responding parts in all of the figures.
10 designates a. door which is hinged at 11 to a casing 12. On this door is shown an ordinary sprmg latch 13.
20 is a metallic plate or door fixture which is provided with a slot 21. This plate in Fig. 1 is shown. under the-latch 13 and affixed to the door by the screws which hold the latch in place. 22 is another plate which is to be afiixed to the door casing on the side opposite the hinges 11 and in line-with the door fixture plate 20. This casing fixture is preferably constructed with a shoulder 23 projecting at right angles from abuts when closed; and with another shoulder 24- projecting at ri ht angles from its opposite side to aid in fastening it securely to the door casing. Its other end 25 is somewhat narrower and is so designed and arranged that it will project through the slot 21 in the Application filed July 18,
of the door latch.
Before specifically describing the other figures of the drawings I will point out the portion of this form of my invention. The two plates are afiixed to the door and to the door casing, respectively. When the Patented Nov. 2%, 32ftfor the reception of the sliding bolt or catch I door is closed the end 25 of plate 22 will,
. project through the slot 21. This end of roof at tachments for doors and its object is --to.;pr}o;-;-
\ 'catch of which will enter the casing fixture will then act .as a strik ing plate iort the slot 26 and ne springlatch, the bolt or holdthe.;do0r closed. Now, if an attempt is made toforce the door away from the casing on the unhinged edge of the door by inserting a jimmy or other pry, these attachments will prevent such an operation because the end 25 of the plate 22 cannot move longitudinally in respect of the plate 29 on the door. The shoulder 23 insertion of a jimmy or other tool at the prevents the latch. If a prying pressure is applied sufiicient to bend the end of the casing fixture plate, the attachments will still prevent the releasing of the door latch because that portion of the plate which engages the latch will then be forced farther on to thedoor latch, bolt or catch.
The common form of spring latch-which is shown is only chosen as illustrative of the invention, and it is to be understood, of
course, that any form of latch or look may 13' is shown with anthe reception of the end 25 of the door casing fixture. In this case no plate 20 is required, butthe operation is sim'lar to that already described.
In the modification shown in Fig. 3, a
The parts shown in Fig. 5 are purpose,
for a similar but may be used, as might also the plates 20 and 22, without being associated plate outside of this slot if the door is forced with the door latch or lock. In this case the'plate 20 is made with an offset so that the part inwhich is the slot 21 is out of line withthe part which is to be secured to the door. The end of plate 22 is bent over as at 27 to form a short hook which may pass through the slot Ql freely, but will be brought'into engagement with the door back, to hold the door closed. v
I have illustrated several modifications of my invention to show that I do not limit myself to any specific form or construction.
What Iclaim is.- v A swinging door, a latch therefor having a sliding catch, a plate on the door under said catch projecting beyond the edge of the door, said plate being provided with a slot, a door casing, and a plate aflixed to said casing having a portion adapted to pass 20 door latch, and being provided with a slot I for the reception 'of the catch of the door 25 latch.
In testimony whereof I have signed my name to this application in the presence of two subscribing witnesses.
GEORGE HENSLE.
