IMPROVEMENT IN DOOR-CHECKS.

Specification forming part of Letters Patent No. 165,607, dated July 13, 1875; application tiled April 2s, 1875.

To all whom it may concern:

Be it known that I, JAMus NAUGHTEN, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Door-Stop, ot' which the following is a specification The object ot' my invention is to provide a stop or retaining device which, when applied to a door, will maintain the latter securely in any open position, and which will prevent it being accidentally closed or swung violently open or shut, while, at the same time, the door maybe readily closed by hand. This stop consists essentiallyT of a brush, pad, or yielding cushion, which is pressed down upon the carpet or iloor by the stress ot' a spiral or other suitable spring, the latter being coupled to the door in such a manner as to have a greater or less pressure imparted to it, as-occasion may require. The attachment of the spring to the pad is preferably such as to permit the ready coupling and uncoupling ot' the two, and serves to enable the substitution of a new spring, or one ot' less or greater tension whenever desired; and, furthermore, the stop is capable ot" being adjusted horizontally toward or away from the door, and circularly, for a purpose which will be hereinafter fully described.

In the accompanying drawing, Figure 1 is a front elevation ot the preferred arrangement of my doorstop, the circumferential guard of the pad being shown in section. Fig. 2 is a side elevation, showing said stop applied to a door, the coupling devices being sectioned. Figs. 3, 4, and 5 represent `modifications of my improvement.

In its preferred form, the stop or retaining device proper consists of a circular brush, A, whose head or stock B is of wood or other suitable material. This head has a circumferential groove, C, withinwhich is sprung the lowermost coil ot' a spiral or helical spring, D, whose uppermost coil terminates in a vertical stem or shank, E. This spring hugs the head B so closely as to eftectually prevent any accidental separation of the two, while, at the same time, the brush may be readily turned around within said lowermost coil, to correct any unequal wear. This mode of applying the spring to the head of the brush allows the ready separation of the two whenever it becomes necessary to fit a new spring to the stop. The stem E of the tension springD, is inserted iu the eye f of the horizontal member F of an angle-plate or bracket F F', whose vertical limb Fl is slotted longitudinally at f', for the reception of an ordinary wood-screw, G, and of a thumb-screw, H. These screws, G and H, serve to imite said angle-bracket either to a block or plate I, or else directly to the door J. K K are wood-screws for securing the block or plate I to the door, whenever such a block or plate is employed, although its use is not essential. The pad AB is coupled to the block I or to the door J, in the following manner L L represent respectively the horizontal and vertical members of an angle-bracket slottedat l l', as more clearly shown in Fig. 2. Ot' these slots, the one Z is traversed by an ordinary screw, M, and a thumb-screw, N, while the other slot l has two screws O O passed through it. The screws M and N enable the brush to be adjusted longitudinally of the slot l, so as to bring the brush in less or greater proximity to the door, as occasion may require. The object of such adjustment is to prevent the brush colliding with the carpet-strip P when the door is closed. In case the brush should wear unevenly, the screw M can be retracted and the brush be rotated as tar as may be desired, after which said brush may be secured to 'its new presentation by driving the screw M lagain into its head, so as to bring a new portion of the brush into service. The screws O O enable the brush to be set at any proper height, either upon the block I or upon the door J. In order to prevent the lowerlnost coil of the spring' coming in contact with the wall or skirting, or with any article of furniture when the door is opened, said coil is completely or partially surrounded with a sott guard or tender, R, that may be composed of rulber, ot' leather, or ot' other suitable materia In the modiiication shown iu Fig. 3, the spring is represented as terminating at bottom with a spur, S, which is adapted to enter a socket T in the head B.

In the modification shown in Fig. 4, the tender R. is represented as located above the lowermost coil ot' the spring, and as being so as to Ipreventany possibility-of thebracket meansfas to retain the ,door to any open posi- `.tion at which it may be placed, withoutfprehand; or, if preferred,-thefpressurefof-lthe said block in its proper position and `to tl1en` screw the retaining devices K K' intorthe door,

after havin g first inserted them iu the perforations i 'i'. This acthaving been accomplished, the bracket F F' is shifted downwardly, so as to compress the sp1ing`D,.aud to causethe brush A to bear upon the vcarpet or door with Y anydesired amount of pressure. lfhelproper pressure of f the .pad having lbeen .thus obtained, the .thumb-screwH -is then tightened,

F F shifting in either direction. i The: frictional contact ofY the `pad ory -bruslrwith .the carpet ory door is so adjustedby the above venting theintentional closureof the door by v-brusl1.1nay be partiallyor wholly relaxed be- Vfore closing thedoor. vThe yielding nature of the spring D enables the brush A to pass over anyiuequalities or irregularities in the floor or carpet without straining,` the stop or couplings; yorlinjury to the carpet.

I claim as new and of my invention- 1. The improved door-stop, consisting essentiallySof-.the yielding and adjustable tioor pad or brush A B, and the separable spring;` D, with the herein described sliding and adjustable attachments as set forth.

#-2. The combination, with a suitable spring and plates, of brush or pad A B, adjustable vertically, laterally, and circular-ly, by means of the attachment L L' and screw M, as speci- Vlied 3; The 'combinatiolnin an adjustable door- 'stop,ot' bruslror iloor .pad A B, and the side j JAS NAUGHTEN.
