DOOR-CHECK.

SPECIFICATIO'N forming part of Letters Patent No. 535,033, dated. March 5, 1895.

Appiioation fiied August 17, 1894. Seria1 No. 520,565. (N'o model.)

Be it known that I, LUTHER THEODORE VELEN, a eitizen of the United States, residing at Cleburne, in the county of Ri1ey and State of Kansas, have invented a new and usefui Improvement in Door- Checks, of which the following is a specification.

My invention reiates 1:0 an improved doorcheck of that class in which a caster-wheel is secured by a yieiding braeket to the side of the door, at its lower edge, and means are provided for automaticaily blocking the rotation of the caster.

The objects of my improvement are, first, to provide improved means f0r blocking the caster in either direction; and, second, t0 provide improved means for securing the bracket to the door, a11 as hereinafter fully set forth.

The accompanying drawings illustrate my nventon.

Figurel represents a front e1evation of the device, in position on the door. Fig. 2 represents a side elevation of the same, showing the caster blocked in b0th directions. Fig. 3 represents a simiiar side eievation, showing the caster blocked in the direotion of openng the door, on1y. Fig. 4 represents a front elevation of the bracket; when removed from the door. Fig. 5 represents a side elevation of two forms of the blocking device.

In the drawings, 2, indicates the door. 3 indcates a bracket formed preferably of sheet metai, bent to form an obtuse angle. One end of said bracket, 4, is provided with a longitudinal slot, 5, and is adapted to be secured to the face of the door. The other arm, 6, of the bracket, is forked at its free end to form bearings for ashaft, 7 npon which is mounted a caster-wheel, 8. An opening, 9, intersecting with the slot 5, is formed at the angle of the bracket so as to permit the passage of a narrow ciamping plate, 10, and the heads of screws, 11, 11, by means of which the bracket is secured to the face of the door. The blocking device consists, essentiaily, of a bracket, 12, suspended by means of a slotted bearing, 13, from the shaft on which the caster is mounted, at one side of the casier, having a pair of arms, 14 and 15, which project beneath the tread of the caster-wheel on opposite sides of a 1ine drawn dametricaily throngh the center of the wheel. Bracket12, is arranged to swing freely on the shaft 7, and also to have a slight radial movementthereon, relatively to the Wheei.

yieiding materiai, as rubber, or leather; and the periphery of the casterwheel is preferably covered with rubber.

The device is secured to the face of the door, s0 as to be adj nstable vertically thereon, by means of the clamping plate 10, and a pair of

screws

11, 11 which are passed through holes in the clamping plaie, securing it ioosely to the door. Ann 4 of the brackel: is then passed frorn above downward between the elamping plate and the face of the door, the clamping plate passing through the opening 9 in the bracket, and the screws entering the slot 5. Upon tightening the screws, the bracket is adjusted upon the door and firmly secured thereto, so that the periphery of the wheel may press with a greater or1ess force, as desired, upon the surface of the fioor beneath the door, and arm 6, being elastic, is put slightly in tension.

The arrangement of

arms

14, and 15, is sucb, that when both of the arms rest upon the flocr, the tread of the caster rests upon the upper surfaces of the arms and is sustained thereby just ciear of the floor. When the arms are in this position the caster is prevented from turning and the door is held at any desired angie. Upon a slight force being exerted t0 move the door in either direction, the bracket3, in which the caster is mounted, yields sufficiently to permit the caster to ride over the obstructing arm, bracket; 12 turning at the Same time with the caster-wheel and assnming, when the door is moved toward c1osing, the position shown in Fg. 3; braoket 12 being prevented from turning with the wheel beyond a certain point, by a stop 17, formed upon arm 6. When the door is swung in the opposite direction, bracket 12 turns with the wheei and assumes first the position shown in Fig. 2, and then passes to the opposite side of the center of the caster from chat; shown in Fig. 3.

Bracket 12, With its

arms

14 and 15, is formed, preferably, from a piece of wre, bent to the form required, as shown at the left 5 5

Arms

14 and 15, are incased in some slightly hand portion of Fig. 5, but tmay be formed from sheet meta1 as shown at the right hand of Fg. 5.

It is obvious that, when ik is desred t0 hold the door in one drecton only, bracket 12 may be formed with ony one blockng arm.

I claim as my nventon- 1. In a door-check, the combination of the bracket adapted to be secured to the face of the door and havng the yeldng arm pro jecting laterally from the door, the casterwhee1 mounted on a shaft in said arm, and the bracket suspended by means of a slot'ced bearin g from the shafl: upon which the casterwhee1 is mounted,said bra.cket having an arm whch projects over the tread of the wheel and is adapted t0 engage the perphery of the whee1 and the surface upon whch the wheel rests, whereby the wheel is blocked at any zo desred point, substantially as set forth.

2. In a door-check, the combnation of the braeket adapted to be secured to the face of the door and havng a yelding arm projecting laterally from the door, the caster-wheel mounted 011 a shaft in sad arm, and the bracketsuspended by means of a slotted bearing from the shaft upon whch the caster wheel is mounted, sad bracket having a. pair of arms which project over the tread. of the wheel on opposite sides of ts center and are adapted 00 engage the periphery of the wheel and the surface upon which the whee1 rests, whereby the whee1 is blocked from turnng in either drection, at any desired point, substantially as set forth.
