DOOR-CHECK.
Application filed August 10, 1909.
To all whom it may concern.-
Be it known that I, GEORGE J. VINTER, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Door-Checks, of which the following is a specification.
This invention relates to an improved door check and the object of the invention is to provide a device of this character which will be comparatively cheap, strong and durable and may be easily attached to a door.
The invention also relates to certain details of construction which will be hereinafter described and claimed reference being had to the accompanying drawings in which Figure 1 represents a door partially open with the improved check attached to the outer lower corner thereof. Fig. 2 is an enlarged front elevation of the improved check. Fig. 3 is a vertical central section through the improved check on line a a, Fig. 2 with the roller in its depressed oper ating position. Fig. 4 is a section similar to Fig. 3 but with the roller and its support in its elevated inoperative position. Fig. 5 is a top plan view of the improved check. Fig. 6 is a detached view of the bracket blank. Fig. 7 is a fragmentary top plan View with a section through the vertical screw member to illustrate the latch construction, the roller being omitted.
In referring to the drawings in detail, like numerals designate like parts.
This improved device consists of a bracket which is attached to a suitable portion of a door or other movable element and a roller journaled in a suitable support with the shank of the support slidably mounted and spring tensioned in a slideway in the bracket.
The purpose of the device is to retard the movement of a door or other object and thus prevent the violent shutting or slamming of the same, or to serve as a stop to frictionally maintain the object in closed or open position.
The preferable form of the bracket employed is illustrated in the drawings and consists of
side members1 and 2 having
apertures3 through which screws are fitted to secure the bracket to a door and a central member which has a
front portion4 and two
side portions5 and 6 which extend parallel to each other and at right angles to the
front portion4 and the
side members1 and 2 Specification of Letters Patent.
Patented June 20, 1911. Serial No. 512,206.
and respectively serve to connect the front portion to said side members. The
front portion4 is provided with a
vertical slot7 of suitable size and length for a purpose to be hereinafter set forth. The top of the vertical space or slideway formed in the central member is closed by a
horizontal top member8 which is preferably formed integral with the bracket and is in fact, in the adaptation shown, a bent continuation of the
front portion4.
The bracket illustrated is stamped from a single piece blank of the form shown in Fig. 6, the front and
side portions4, 5 and 6 of the middle member and the horizontal
top member8 of the blank being formed by bending the blank in suitable dies from the flat shape shown in Fig. 6 to the finished form shown in the other figures.
A
roller9 is rotatably mount d on a
pintle10 fitted in the lower extremity of the depending forks of the lower bifurcated
portion11 of a support. The
upper portion12 of the support is a vertical rod of substantially a square form in cross section which is slidably mounted in the slideway in the central member of the bracket. This
rod12 is attached rigidly at its lower end to the middle of the top bridge connecting the forks of the bifurcated portion by fitting the end through an opening and riveting it in place as shown in Figs. 3 and 4. Theroller support is secured to the bracket and also limited in its vertical movement by means of a
horizontal screw13 which passes through the
slot7 in the front portion of the central member and screws into a lateral opening in the
rod12 as shown in Figs. 3 and 4. The
screw13 also serves the pur pose of a frictional locking means for retaining the roller in a vertically adjusted position. When said screw is screwed tightly into the
portion12, the head of the screw will be forced into frictional contact with the edges of the
slot7.
Provision is made for regulating the vertical position of the roller and its support which consists of a
screw14 which passes through a
central opening15 in the
top member8 see Fig. 6 and screws into-a vertical screw threaded
socket16 in the
rod12 as shown in Fig. 3. By rotating the
screw14 the roller and its support may be raised or lowered so that the roller may be accurately adjusted with respect to the floor or other surface against which it engages.
To yieldingly maintain the roller in operative contact a
coil spring17 is placed in loosely encircling position around the shank of the screw l-it with its ends respectively pressing against the upper end of the
rod12 and the under surface of the horizontal
top member8 see Figs. 3 and 4.
A latch is provided to secure the roller in an elevated inoperative position when de sired which consists of an
arm18 attached at one end to the
top member8 by a pivot pin or
screw19 which is fitted in the opening 20 in the top member and is adapted to be turned on its pivot to engage in a recess or
depression21 formed in the side of the
screw14.
The roller is preferably made of hard pressed felt or other suitable material and the remaining portions of the device are of metal most suitable for the purpose.
I claim:
In a device of the class described, a bracket having a central member provided with a vertical slideway, a horizontal top member having an opening and side members through which screws or other fasteners are fitted to secure the bracket to a door, in combination with a support carrying a rotatable element at its lower eX- treinity and having an upper element slidably mounted in the slideway of the bracket and provided with a longitudinally extending socket and a screw passing loosely through the horizontal top member and engaging in the socket of the upper element of the support.
