GEORGE W. CUMMINGS, OF MORGANTOWN, WEST VIRGINIA. I

DRAFT-PREVENTER OR WEATHER-STRIP.

A Specification of Letters Patent. Patented Sept. 10, 1918.

Application filed August 24, 1917. Serial No. 188,044.

To all whom it may concern:

Be it known that I, GEORGE W. CUMMINGS, a citizen of the United States, residing at Morgantown, in the county of Monongalia and State of WVest Virginia, have invented certain new and useful Improvements ,in Draft-Preventers or Weather-Strips; 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 relates to improvements in draft preventers or weather strips.

The object of the invention is to provide means especially applicable to doors, whereby when the door is closed, the strip or plate will be actuated to be moved downwardly against the sill thereof, thus preventing a draft from having passage under the lower edge of the door. r

A still further object of this invention is to provide a door actuating rod, which is pivotally secured to a bell crank lever, Which bell crank lever is pivotally securedto a bracket, which is secured to the door, a plate carried by the actuated rod, and an actuating member carried by the door frame, whereby upon the closing of the door, the bell crank lever will be held outwardly, urging the operating rod downwardly and moving the plate downwardly into engagement with the sill for closing the crack or space between the lower edge of the door and sill, thus preventing a passage of air therethrough or under.

A still further object of this invention is to provide a draft preventer or weather strip of this character, which will be simple, practical and comparatively inexpensive in construction and one that can be maunfactured and sold at a low cost.

lVith these and other objects in View, the invention consist in the novel combination and arrangement of parts as will be hereinafter more fully described and set forth in the claim hereto appended.

In the drawing:

Figure 1 is a front elevation illustrating my improved draft preventer or weather strip as applied to a door and as made in accordance with this invention.

Fig. 2 i a vertical sectional View of the same.

Fig. 3 is a sectional view illustrating the manner in which the spring adjusting collar is secured to the operatlng rod.

Like numerals of reference designate corpose of which will be hereinafter more fully described.

An L-shaped bracket 5 is secured by one flange as at 6 to the front face of the door at the upper longitudinal edge thereof and centrally of the side edges, While its other flange is arranged at right angles thereto. A bell crank lever 7 is pivotally secured as at 8 to the right angularly extending flange of the bracket 5.

An operating rod 9 has its upper end bifurcated as at 10, which bifurcated end is pivotally secured as at 11 to one arm of the bell cranklever 7. The lower or free end of the rod isadapted to extend through the rightan'gularly extending lip 12 of the attaching plate 13, which plate is secured as at 14 to the front face of the door, centrally of the sides thereof and intermediate the ends thereof. 7 j 7 An adjustable collar 15 is slidably arrangedon the operating rod 9 and is adapted to be held in various adjusted positions thereon by a suitable type of thumb screw 16, extending transversely therethrough and engaging the operating rod to permit the collar to be moved vertically upon the rod and held in its adjusted position.

A coiled spring 17 surrounds the operating rod 9 and has one end abutting the upper side of the right angularly extending lip 12 of the plate 13 as shown at 18, while its opposite end is arranged in spaced relation to the under side of the collar 15. The upper convolution of the coiled spring 17 is extended upwardly in a vertical plane and parallel with the operating rod and extends up through and beyond the adjusting collar 15 as at 19.

A flexible weather strip carrying plate 20 is slidably arranged on the front face of the door adjacent the lower edge thereof and is movable Vertically in a pair of spaced guides 21, which guides are secured to the front face of the door as at 22 and their lower ends terminating adjacent the lower longitudinal edge of the door. The plate is vertically movable under the guides 21 and is supported by a supporting rod 23, which is formed of a single length of material, looped at its medial portion to provide a bearing eye 24. The ends of the bearing eye are bent downwardly at right angles thereto and twisted as at 26, and the lower ends diverging as at 27 provide supporting arms 28, which are secured to the front face of the plate 20 as at 29. The bearing eye is slidably arranged on the lower end of the operating rod and is disposed between the under side of the adjustable collar 15 and bears against the upper convolution of the spring 17 so as to permit the supporting plate 20 to be adjusted to compensate for various distances of space defined between the lower edge of the door and the sill, which is designated 30 in the drawing.

A flexible weather strip 31 is secured as at 32 to the rear side of the plate and is adapted to have contact with the upper side of the sill 30 when the door is in closed position, thus preventing a space from being defined between the lower edge of the door and sill and preventing the passage of air there- .through or under.

It is to be understood that the plate 20 is operated when the door is closed through the medium of the operating rod 9 and bell crank lever 7, which has engagement with the actuating member 4: when the door is in closed position as shown in Fig. 2.

It can also be seen that byadjusting the thumb screw 16 in the collar 15, that the plate 20 may be raised or lowered through the medium of the supporting rod 23 and collar 15, thus various size spaces defined I by the lower'edge of the door and sill may be kept closed and thus prevent a draft from passing thereunder when the door is in closed position.

What is claimed is:

A device of the class described including a frame, a door hingedly mounted in said frame, a bracket rigidly secured to the front face of the door at the upper longitudinal edge thereof, a bell crank lever pivotally mounted on the bracket, an attaching plate secured to the door intermediate the ends thereof, an operating rod pivotally secured to one. arm of the bell crank lever having its opposite end slidably arranged through the attaching plate, a flexible collar slidably and adjustably mounted on the operating rod, guides secured to the front side of the door, a plate slidable beneath the guides and in engagement with the door, a supporting arm secured to the plate having a bearing eye slidably arranged on the operating rod, a coiled spring surrounding said operating rod and bearing against the attaching plate having its opposite end extended up through the adjusting collar, said bearing eye of the sup porting rod slidably arranged on the operating rod and located between the adjusting collar and the upper convolution of the coiled spring,-and a flexible strip secured to the rear side of the plate, and said plate adapted to be moved downwardly into engagement with the lower sill of the door frame during the closing movement of the door through the medium of the bell crank lever and operating rod, as and for the pur pose specified.

In testimony whereof I aflix my signature in presence of two witnesses.

GEORGE W. CUMlWINGS.
