I L. P. SPANGLER,
DOOR GHBOK. APPLICATION FILED JULY 2, 1909.
Patented Feb. 21,
LOUIS P. SPANGLER, OF DENVER, COLORADO.
DOOR-CHECK.
Specification of Letters Patent.
Patented Feb. 21, 1911.
Application filed July 2, 1909. Serial No. 505,734.
To all whom it may concern:
Be it known that I, LOUIS P. SPANGLER, a citizen of the United States, residing in the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Door-Checks, of which the following is a specification.
My invention relates to improvements in door checks, and more particularly to that class of door checks which allow the door to be opened either part way or all the way, at the will of the occupant of the house.
My invention may also be used on windows, transoms and the like.
One of the objects of my invention is to provide a means for locking the door to its jamb in such a manner that the door may be partially opened and still remain locked thus enabling the person within to see who is without and still prevent the outsider from breaking or forcing his way inside.
Another object of my invention is to pro-- I vide a bolt which is simple, strong, and economical and which may be attached to any doors windows, etc.
The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.
Referenceis to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.
Figure 1 is a perspective view showing the door partly open. Fig. 2 is a transverse section taken through the invention, door and jamb, showing the relation of the different parts when the door is locked. Fig. 3 is a sectional elevation view of a door j amb shown inverted and with my invention ap plied thereto. Fig. 4 is a perspective view of the parts shown in Fig. 3. Fig. 5 is a perspective of the sleeve and bar detached from the door jamb.
Let the numeral 1 designate the door, 2 the amb and 3 and 4 pockets formed in the door and door j amb respectively. Slidably mounted in the pocket 4 of the jamb is a sleeve member 5 which is slightly curved throughout its length. This sleeve member is open at one extremity as indicated by the numeral 6, and closed at its opposite extremity by the projection 7 which extends some distance beyond and at right angles to the Surface 8 of the sleeve, the purpose of which will be hereinafter explained. In the surface 8 of the said sleeve is formed an opening 9 which extends the entire length thereof, and the purpose of which will be described hereafter.
Slidably mounted within the sleeve 5 is a bar 10, which is provided with a central longitudinally disposed slot 11 beginning near the extremity 12 of the bar and terminating in an enlarged circular opening 13 formed near its opposite extremity. At this extremity of the bar is formed a projection14 which corresponds with the projection 7 of the sleeve 5 and extends through the opening 9 of the said sleeve. The purpose of the opening therefore, is to allow the bar with its projection 14 to be moved back and forth in the sleeve. The bar is also provided with a finger piece 15 which normally extends beyond the sleeve so that the said bar may be withdrawn when necessary.
At the mouth of the pocket 4 is formed a raised portion or ledge 16 which acts as a stop and prevents the bar and sleeve from being entirely withdrawn from the pocket 4 after my invention has been assembled. This is accomplished by means of the projections 7 and 14, which are formed on the sleeve and bar respectively, coming in contact with the said portion 16, when the said parts 7 and 14 are withdrawn from the pocket 4. To be more accurate, the projection 14 directly engages the portion 16 and the projection 7 engages the projection 14. As before stated, these projections 7 and 14 extend some distance beyond the faces of the sleeve and bar, in order that they may engage the stop 16. When the sleeve 5 and bar 10 have been placed in the pocket 4 an angle face-plate 17 is fitted in the jamb over the said pocket and secures the said parts in their assembled relation. The plate is pro- Vided with an opening 18 in one surface thereof and an opening 19 in its other surface. It will be noted by reference to Fig. 2, that, if desired, the plate 17 may extend within the socket to maintain the flange in line to abut the stop 16.
Fitted in the opening 19 and extending the width of the stop 16 is a channel member 20, which is provided with side flanges 21 and a circular opening of orifice 22. This opening 22 is in alinement with the recess 23, formed in the stop 16. It may be here stated that this recess 23 and opening 22 are at times in alinement with the opening 13 of the bar 10 and the opening 24 formed opening 29 in the door and openings 30 formed in each side of the cylindrical sleeve 31. This sleeve 31 receives the bolt and is of such a length as to allow the entire bolt to be concealed therein when the door is unfastened. This bolt is operated by turning the knob 28 which in turn operates the pinion extremity 27 thereof which meshes with the rack member of said bolt. The bolt is further provided with a circumferential groove 32 which has loosely fitted therein a spring ring 33, which serves the purpose of a packing and causes a close fit between the bolt and sleeve 31. The forward extremity of the bolt is provided with a re duced portion or neck 34, which enables the said bolt to operate in the opening 11 formed in the bar 10. Thus, when the door is locked, the bar 10 must first be extended the house to see who is on the outside.
and concealed within the sleeve 31.
from its sleeve to permit unlocking to open the door since, otherwise, the bolt is partly released but is locked to the sleeve which only permits opening to the extent shown in Fig. 1. If it were not for this neck portion 34 of the bolt, the bar could not be inserted or placed in the pocket l, as the opening 11 of said bar is not of sufficient width to allow said bar to slide upon the bolt 25.
35 represents the ordinary knob plate which is also secured to the door by any well known means, such, as screws, etc.
The object of the recess 23 in the stop 16 is to receive the forward extremity of the bolt 25, as is clearly illustrated in Fig. 2 of the drawing. When the forward extremity of the bolt is within the recess 23 the door is absolutely locked against any movement whatsoever from the outside. In case the occupant wishes to see who is on the outside the bolt 25 will have to be withdrawn from the recess 23, and also the opening 22 formed in the plate 19. \Vhen the plate 19 is cleared by the bolt the door may then be pushed open a distance equal to the length of the sleeve 5 and bar 10, but no farther, as shown in Fig. 1 of the drawing. This distance is probably 3 or 4: inches; at any rate it is suflicient to enable the occupant of If it is desired to open the door completely (referring to Fig. 2 of the drawing) the bolt is withdrawn entirely from the jamb through the openings 13 and 24 of the bar and sleeve As soon as the forward extremity of the bolt 25 clears the sleeve member 5, the door is then free to be swung wide open.
What I claim is:
1. A door check comprising a bolt slidably mounted 011 a door, a sleeve slidably mounted in the door jamb and having an opening for said bolt, means operating in said sleeve for normally locking said bolt in said opening, said means being adapted to release said bolt only when the door is closed.
2. A door check comprising a bolt slidably mounted on a door andhaving a reduced neck, a main opening in the door j amb for receiving said bolt, a sleevesliding in said door jamb and havingfa subordinate opening adapted to register with said main opening, a slotted member sliding on said neck and in said sleeve, said member having an enlarged cutaway portion at its inner end and being extensible when said sleeve is in retracted position to bring said cutaway portion into register with said main and subordinate openings whereby said bolt may be retracted.
3. A door check comprising a bolt slidably mounted on a door and having a reduced neck, a main opening in the door jamb for receiving the head of said bolt, a sleeve slidable in said door jamb having a subordinate opening adapted to register with said main opening, a stop on said sleeve for limiting slotted member sliding on said reduced neck and in said sleeve and having an enlarged cutaway portion at its inner end, and means for preventing extension of said outward movement thereof, a I
slotted member beyond said sleeve when said sleeve is in outer position.
4. A door check comprising a bolt slidably mounted on a door and having a re duced neck, a sleeve sliding in the door jamb and having a cutout portion for the passage of the head of the bolt, a main opening for the reception of the head of said bolt through said cutout portion, and a slotted member sliding on the neck of said bolt and in said sleeve for locking said bolt thereto, said member having an enlarged opening at the inner end of said slot, a stop on said jamb, a flange on said sleeve coacting with said stop, and a like flange on said slotted member, said neck being long enough to permit withdrawal of the bolt headfrom the main opening when locked to said sleeve.
In testimony whereof I affix my signature, in presence of two witnesses.
LOUIS P. SPANGLER.
