Doon-CHECK.

SPECIFICATION forming part of Letters Patent No. 528,049, dated October 23,1894. l

i Application filled February 27', 1894.` Serial No. 501,662. (No Vinolel.)

To otZZ whom it may concern:

Be it known that I,` HERMAN V. WERTZ- BERGER, of Glenwood Springs, in the county` of Garfield and State of Colorado, have invented certain new and `useful Improvements in Door-Checks; and I do hereby declare the following to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same.

This invention contemplates certain new and useful improvements in door-checks, and has for its object the production of improved, simple and highly efIic-ient means for holding a door or swinging window at any point in the arc of its intended movement, and which will act as a bumper against a wall or any vertical obstruction.

The invention comprises the novel features of construction, and also the combination and arrangement of parts, substantially as hereinafterfully set forth and particularlypointed out in the claims.

In the accompanying drawingsz--Figure l vis a Vertical longitudinal sectional view of my improved door or Window-check. Fig. 2 is a front elevation with parts removed and in section. Fig. 3 is a front elevation of the device as a whole. Fig. 4 is a top end View. Fig. 5 is a cross-sectional View on the line .fr-.c, Fig. 2. Fig. 6 is a similar view on the line y-y, Fig. 2.

Referring to the drawings, A designates a frame which is designed to be rigidly secured to a door or window near the bottom thereof by means of nails orscrews passed through holes o.. From the front face of this frame project overhanging flanges o. and a stop or cross-piece t2-at the upper end of said flanges. From about the center to the lower end of this frameA are two parallel rack-bars a3 located within the space between the overhanging flanges.

B is an adjustable box or frame the sides of which have flanges b which lit snug beneath the overhanging flanges of the stationary frame on which said box or frame B is designed to be vertically adj ustable. The

upper end of this frame is extended to 4form a thumb-piece b which upon coming in contact with stop a2 limits the movement of the box or frame B. This latter is divided by a .i integral therewith, is a ratchet wheel d.

horizontal partition b2 into upper and lower compartments, the sides and top of the latter being extended outwardly beyond the former. In the upper chamber is a shaft O mounted in the sides of the boxor frame and upon it are two gear-wheels CZ whic'njare designed to intermesh with rack-bars a3 of frame A, and between these gear wheels, preferably formed A pawl or lever D fulcrumed at d2 is designed to engage this ratchet wheel d', being so held in engagement by a spring da secured at d4. The upper end of pawl or lever Dis projected through a slot e inthe front of box or frame B, which slot permits the pawl or lever to be turned on its fulcrum to free it from engagement with the ratchet wheel. The lower chamber of box or frame B is open at its front and bottom and in it is mounted a roller E, whose shaft is supported by the sides of the box or frame. This roller is preferably made of vulcanized rubber, or other semi-pliable material, and its toothed periphery extends beyond the front and bottom of the box, its forward projection being beyond any other projecting portion of the device. Thus the roller will act as a bumper upon coming in contact with a wall or other vertical obstruction. The lower projecting portion is designed to bear against the door or windowill or ledge and by reason of the friotional contact will hold the door or window at any point Within the arc of its intended movement. To adjust the roller and its holding box or frame the operator disengages the pawl or lever from contact with the ratchetwheel and by grasping the thumb-piece the box can be moved up or down, the gear-wheels engaging the rack -bars of the stationary frame.

From what has been said it will be seen that I have produced a combined check and bumper for doors and swinging windows, which is simple in construction, inexpensive. and not liable to readily get out of order, and

that the position of the friction-roller can be j readily adj usted and held at any point, and that the same will serve as a bumper and protect the other parts of the device from injury upon contact with a wall or other obstruction.

I claim as my invention-- 1. The herein described improved door- ICO check, comprising the stationary frame having guide-ways and rack-bars,the box or frame movable in said guide-ways, the frictional roller carried by said box or frame, the gearwheels engaging said rack-bars, and means for locking the same,substantiallyas set forth.

2. The herein-described improved doorcheck, comprising the stationary frame havingguide-Ways and rack-bars, thebox or frame movable in said guide-ways and having a slot in its front wall, the frictional roller carried by said box or frame at its lower end, the gear wheels engaging said rack bars, the ratchet-wheel and the pawl or lever engaging said ratchet wheel and projected through said slot, substantially as set forth.

3. The herein described improved doorcheck, comprising the Vframe having parallel overhanging anges, an upper stop, and parzo allel rack-bars, the box or frame provided 'through said slot in said box or frame, substantially as set forth.

1n testimony whereof I have signed this specification in the presence of two subscribing witnesses.
