SIIJAS NOBTHEY, OF WATERLOO, IOWA.
Specification of Letters Patent.
Patented Nov. 1 1', 1913.
Application filed April 17, 1913. Serial No. 761,744.
To all whom it may concern:
Be it known that I, SILAS NORTI-IEY, a citizen of the United States, resident of l/Vaterloo, in the county of Blackhawk and State of Iowa, have made a certain new and useful Invention in Door-Fasteners; and. I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
Figure 1 is a front view of the invention, as applied. Fig. 2 is a side view of the same. Fig. 3 is a front view of a modification of the invention as applied. Fig. 4; is a face view of the invention taken from the inner side of the door. Fig. 5 is a section on the line 55, Fig. 3.
The invention has relation to door fastenors, designed mainly for use with refrigerator doors, and it consists in the novel construction and combinations of parts as hereinafter set forth.
In the accompanying drawings illustrating the invention, the numeral 1, designates a refrigerator door, having the usual tapered or inclined edge walls 2, which engage the similarly formed edge walls 3, of the jainb or door casing in a wedging manner to insure a tight fit.
Owing to the wedging fit of the door in its casing there is a strong tendency of the door to open, which is the more marked in heavy or large doors. It is designed by the present invention to provide a strong fastening composed of few parts, easily applied to the door, and simple in operation which will effectually resist this tendency of the door to open, so that not only will the door he held securely closed, but no undue stress will be exerted by the door upon the parts of the fastener to cause such parts to become loose or disengaged. To this end, the numeral 1, designates a vertical latch bar, located with its outer edge 5, in line or approximately in line with the edge of the door, said latch bar having a vertical slot 6, located close to the outer edge 5, thereof, a bolt or bolts 7 being secured to the door and working in said slot to provide for an accurate vertical movement of the latch bar.
A straight vertical keeper 8, has its inner edge9 located in line or nearly so with the edge of the door amb, 111 approximately contiguous relation to the outer edge 5 of the latch bar, two bolts or screws 10 engaging perforations of the keeper and serving to secure it to the door jainb, said bolts or screws being approximately in vertical alinement and c ose to the edge of the jamb.
The latch bar is provided with a short lug or projection 11, engaging a notch or seat 12 of the keeper, the parts being located so closely together that this lug need not be long. The notch or seat of the keeper bein open laterally at 13, the lug is also enabled to be made straight.
The latch bar is provided with an openend recess or notch 14, with which the inner end of an operating lever 15 has engagement to move the latch bar up and down or vertically and disengage or engage the latch bar with the keeper. The lug or projection 11 being, when disengaged, above the keeper, will through force of gravity tend to have engagement with the keeper, when the door is closed.
The operating lever is fulorumed intermediately of its length at 16, and has a long handle arm 17 This lever is preferably made with an integral pivot pin 18, engaging a perforation of the door, said pin having an inner end 19, upon which fits at the inside of the door an inner operating lever 20, a set screw 21 engaging the inner lever and the squared portion of said pin. The latch or fastener may thus be worked from either side of the door.
The fastener is preferably operated by a spring, to automatically cause the fastener to engage the keeper. A spring for this purpose is shown at 22, and a modification is shown at 23. It is also preferred to use a roller bearing 24 in the keeper, to lessen friction in the operation of the fastener.
What I claim is 1. A door fastener, comprising a re ciprocatory latch bar having a slot and a central open-end recess, a securing pin work ing in said slot, a straight vertical keeper having its inner edge in approximately contiguous relation to the outer edge of said bar and being provided with an open-top notch, said latch bar having a short straight lug in the plane of the bar engaging the notch of said keeper and an operating lever having awork arm in the plane of the lever engaging the open-end notch of the latch bar.
2. A door fastener, comprising a reciprocatory latch bar having slots at its upper and lower ends and a central openencl recess, securing pins working in said slots, straight vertical keepers having their inner edges in approximately contiguous relation to the outer edge of the latch bar and being provided with upper open-top notches, said latch bar having at its upper and lower ends shortstraight lugs in the plane of the bar engaging the notches of said keepers, an operating lever having a work arm in the plane of the lever engaging the open-end notch of the latch bar, and a spring in line with the latch bar.
In testimony whereof I affix my signature, in presence of two Witnesses.
