UNITED STATES g PATENT OFFICE.
ISAAC J. WELLS, OF VVILLMAR, MINNESOTA.
IMPROVEMENT IN DOOR-STOPS.
Specification forming part of Letters Patent No. 116,654, dated July 4, 1871 5 antcdated J u To all whom t may concern:
Beit known that I, ISAAC J. WELLs, of Willmar, in the county of Kandiyohi and State of Minnesota, have invented a new and Improved Door- Stop and Holder; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing making a part of this specification, in which- Figure I is a sectional elevation 5 Fig. 2, a perspective view of the casting for the door 5 and Fig. 3, a'perspective view ot' the casting for the iioor.
This invention has for its object improvement in devices designed to prevent a door when opened from swinging back so far as to strike the wall, and also to hold it open, so that it may not close prematurely or swing to and i'ro. The invention consists of two transversely-grooved plates or castings-one let into the bottom edge oi'a door, flush with the surface ofthe same, and the other secured to the tloor by countersunk screws passin through the springs or elastic blocks on which it rests-the arrangement being such that, when the door is swun open, the two castings are looked together, a-nd when it is to be shut they may be disengaged without difficulty. A
The advantages oi' this construction and arrangement are cheapness, eficiencv, and facility of removal and attachment of parts wit-hout injury to the door or giving the door an unusual appearance.
Referring to the drawing, A is a section of a door 5 a, the casting aforesaid, which is let crosswise into the bottom of the door 5 b, the prominen ce upon the door-castin 5 c, the floor-castin g 5 (1 the iirst incline on the floor-casting; e, the depression in the oor-castin g 5 f, the second incline on the floor-casting; g, the springs-rubber in this instance, but not necessarily so, and of the proper height, when secured to the oor and surmounted by the casting c, to place the latterjust in the path of the casting a. The springs g should be secured to the oor at a point far enough from the wall to prevent the door from striking it.
As the door swings open the casting n, coming in contactwith. the casting c, glides up the first incline d of the latter until the prominence b enters the depression c, and then up the second inclinef, until stopped by the resistance ofthe springs, when the prominence b glides back into the depression c. rlhe compressing of the springs g, which takes place while the casting a is sliding up the incline d ofthe casting c, causes said springs to press the lower casting against the upper one powerfulhv enough to hold the door stationary, but does not present any great diiiiculty to the drawing of the door oli' from the casting o when it is desired to shut it.
Having thus described my invention, what I claim as new. and desire to secure by Letters Patent, is-
The shouldered casting al b, let Hush into the door A, and the casting c provided with the notch c, and secured to the iioor by countersunk screws passing through the springs g g, as shown and described.
ISAAC J. WELLS.
