'; -3 Claims. (01. 18-82) My present: invention relates a door check,

mobile doors provide 'a'door check for-a hinged door whereby v thedoormaybe readily swung about its hinges, but frictionally retained in any desired position against easy displacementor swinging by wind,

gravity, or similar-force) Another object is to provide a very simple positive door stop inconnection with the foregoing structure. 1

Another important object of this invention is to provide a'doo'r check of this class which is concealed except when the door is open, and then is not more visible than other door stops.

A further important object of this invention is to provide novel and readily accessible means for adjusting the amount of frictional resistance against the easy swinging or displacement of the door in either direction.

An object also of this invention is to provide novel-means of lubricating and of retaining the 1 lubrication of the sliding rod in the gripping A further object of this inventionis to providea door check of this class which. is simple and economical of construction, durable, and ,which will not-readily deteriorate or get out of- With these and other objectsin new as-will' appear hereinafter, I have devised a..door .check having certain novel features of construction, as

will be hereinafter described in detail and par-,

v ticularly set forth in the appended claims, refer-- ence being had to the accompanying drawing, and to the characters of reference thereon, which form apart. of this application, in which: Fig. 1 is asectional view in plan, showing a 1 preferred construction of my door check, and embodiment thereof in an automobile body. and

door; I

' thereof, taken through 2-2 of Fig. 1;

Fig. 3 .is a fragmentary sectional view taken from the edge of the door at 3-3 of Fig. 2; and, Fig. 4 is a fragmentary section thereof taken at4--4ofFig.2.-'

. In the drawing the body isidesignated I, and

1 the door 2 is mounted on .the body by'ahinge v.or hinges 3. The abutting faces l and! of f the body and door, that is, thefaces which-engage each other when the door is closed, are prefer- 1 5 ably relieved, as in present automobileconstruc particularly adapted though not limited to auto- I Fig. 2 is a fragmentary sectional elevation tion. The installation of my door check, however, is not limited tothe identical abutting faces I shown.

On the plate or member I, forming the abutting face of; the body or door casing, is mounted an- 5 eye member or clevis H which is preferably bolted thereto. I v

g The corresponding plate or member 2'? of the door 2 has a reinforcing plate 4. At the'inner side of this plate is positioned a slide in the 10 form ofja bracket l2 which is provided. at its upper and lower ends with aligned trunnions l2 which are pivotally mounted in the bearing or eye portions l3 of eye bolts l3, the shanks of which extend outwardly through the plates 4 and ll 2* and'are secured in place by nuts 13 at the outer side of the plate 2. The centralportion of the bracket I! has an elongated hub l2 which .has a threaded hole l2 tapered from the outer f end. A sleeve H is correspondingly threaded a at the end M and is adjustably screwed into the threaded hole l2. The threaded end is longitudinally slotted, as indicated by so that the split end is contracted as the sleeve is screwed into the hub. The sleeve is provided with an 25 axial bore H inwhich is slidably mounted a rod IS. The outer end of the rod I5 is pivotally connected, on a verticalaxis, to the eye member or clevis II. On the inner end of the rod is a stop consisting of nuts l6 and I1. Intermediate 30 the ends of the sleeve l4, and immediately surrounding the bore, is a channel in which a packing or lubricating washer I8 is positioned'for lubricating the rod sliding therethrough. I

The outer end 'of the sleeve is provided with 35, a transverse slot to facilitate the adjustment of the sleeve by screwing the same into or out of the tapered threaded hole I2 As the door 2 is opened or closed, the rod l5 slides through the sleeve, the pivotal mountings 4o of the outer end of the rod and of the slide or bracket l2 allowing free movement of the .rod laterally. The portions of the plates 2* and 4, through which the sleeve It extends, are horizontally elongated to permit such free movement. I

To increase. or reduce the resistance of the sliding of the rod l5 through the sleeve, the sleeve is 'adjustedinto' or out of the tapered threaded hole.

The stop nut l6 engages the inner side of the bracket l2 when'this nut serves as stop means to limit theopening of the door.

Though I have shown and described the parti- 'cular construction, I do not wish to .be' -limited to the same, but desire. to include in the scope IQ of my invention, the construction, combination, and arrangement substantially as set forth in the appended claims.

I claim: I

1. In a door check, a door casing and a door hinged thereon, each having abutting faces, a bracket within the door and pivotally mounted on the back side of its abutting face on an axis parallel to the hinged axis of the door, a rod pivoted at one end on the casing substantially in the plane of its abuting face, and a screw contracting sleeve on the bracket, the other end portion of the rod extending slidably and frictionally through the axial portion of the sleeve, one end of the sleeve extending through the abutting face of the door, and having means at said end for longitudinally adjusting the sleeve for contracting the same.

2. In a door check, a door casing and a door hinged thereon, each having abutting faces, a friction slide on one of the former immediately behind its abutting face, a rod pivoted at one end on the abutting face of the other of the former, and a screw contracting sleeve on the slide, the other end portion of the rod extending slidably and frictionally through the axial portion of the sleeve, one end of the sleeve extending through the abutting face of the member on which the slide is mounted, the latter end of the sleeve having means for longitudinally adjusting the sleeve for contracting the same diametrically.

3. In a door check, a door casing and a door hinged thereon, each having abutting faces, a bracket within one of the former and pivotally mounted on the back side of its abutting face on an axis parallel to the hinged axis of the door, a rod pivoted at one end on the abutting face of the other of the former, and a screw contracting sleeve on the bracket, the other end portion of the rod extending slidably and frictionaliy through the axial portion of the sleeve, one end of the sleeve extending through the abutting face of the member on which the bracket is mounted, the latter end of the sleeve having means for longitudinally adjusting the sleeve for contracting the same diametrically.
