The upper end of the'dog I4 is reduced and secured to and ex tending through the reduced portion is a headed pin I6 that also extends through a slot I1 in the 30 upper end portion of the tube 4, for disposal in the path of the door to be engaged by the latter for moving the hooked lower end YI3 of the dog or catch I4 from the hook I2 of the rod 8, and against the action of a coil spring I8 that lhas its end convolutions engaged with the reduced up- , per end of the dog and the tube`4 respectively as Figure 5 is a sectional view taken approxi mately on line 5-5 of Figure 4, looking in the ¿clearly shown in Figure 4, which likewise dis closes the. fact that the coil spring is heldin po-direction of the arrows. sition, due to the fact that a portion thereof sur-v Referring to the drawing in detail, and par 40 ticularly to Figure 1, it will be noted that my door rounds the headed pin. Surrounding the shaft I0 in coiled formation stop is adapted to be set into the floor in the path of a swinging door, and for that purpose it and having one end fixed thereto is a spring I9 is provided with a substantially U-shaped frame which has its opposite end fixed to the pinion 9 adjacent the periphery thereof, by a pin as shown 45 45 having secured to the upper ends of the parallel and by that structure it will be obvious that the arms thereof an attaching plate 2 which extends outwardly beyond the arms and has openings bolt 6 is urged outwardly of its tube 3 or in pro adjacent its outer ends to receive screws or like jected position as shown in Figure 4. However, securing means for securing the frame within the it will be further obvious that the bolt isY held within itsV tube by the engagement of the hooked 50 floor and of course with the plate countersunk ' lower end I3 with-the hook I2, vas shown in full therein, as clearly shown in Figure 1. Fixed to the lower or bight portion of the lines in Figure 4. When the parts- are arranged frame, as well as to the attaching plate 2 for in the latter mentioned position, and the door is disposal in close proximity to the arms of the 55 frame are tubes 3 and 4 respectively which are moved to open position, to contact the head of the pin I6, the rod will be released from the dog, , 55 2 2,131,630 and the spring I9 will move the bolt and rod to the full line position of Figure 4, and thereby the bolt will be arranged in the path of the door, with the latter between the projecting upper end of the tube 4 and the bolt, as clearly shown in Fig ure 1. I preferably provide a` closure cap 20 for the projecting upper end of the tube 3, and which is slidably mounted thereon and secured thereto 10 in any manner, and the cap is provided with a slot to accommodate the headed pin I6. How ever, any suitable means may be employed for closing the upper end of the tube 4. t It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent. It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided 20 that such changes fall within the scope of the appended claims.
