L. Q. HOEN DOORCHECK, AUTOMATIC LATCH, AND NIGHT HOOK Filed Sept. 27, 1927 W i %%m M? LOUIS Q. HOEN', OF NEWTON, IOWA.

DOORCZ-IECK, AUTOMATIC LATCH, AND NIGHT HOOK.

Application filed September W, 1927.

The object of my invention is to provide a door check, automatic latch and night heck of simple, durable and comparatively inexpensive construction.

Another object of my invention is provide a door check wherein the door is positively checked when closed violently and caused to rebound until motion has been slowed down where it will close gently, the

check itself operating to close tne door as soon as its motion has been sufiiciently slowed down. I

Still a further object is to provide pair of members, one mounted on a door jamb and the other on a door, which members coact with ea en other for accomplishing the purpose set forth in the last object.

Still a further object is to provide an arm having a bumper roller thereon which arm is resiliently held in either of two positions, one being a position where the check mechanism is set and the other being a position wvhere it is not set and where it serves to hold the door in closedposition.

Still av further object is to provide means on the door for engaging the bumper roller and causing it'to move from a set to a non set position and further means for preventing movement toward non-set position except 30 when the door closes gently;

Still a further object is to provide a night hook on my latch whereby it may be locked when so desired.

With these and other objects in view my invention consists in the construction. arrangement and combination of ti various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims,,and-illustrated in the accompanying drawings, in which:

Figure 1 is a front elevation of one member of my door check showing the bumper roller in set position.

Figure 2 is a front elevation of the other member used in my construction which coacts with the member illustrated inFigure 1.

Figure 3 is a side elevation of the member illustrated in Figure 2 and looking in the direction of. the arrow' Figure 4: is a sectional view taken on the lines 4-4 of Figure 1; and

Figures 5 and 6 are views similar to Figure l showing the parts of the check mecha nism in different positions.

Serial No. 222,347.

On the accompanying drawings I have used the reference character A to indicate generally the 'member of my door check structure which is attached to the door jamb 10. The reference character B indicates the other member which is attached to the door frame 12.

The member A comprises a pair of attaching ears 1% which may be secured to a spacer block 16 which in turn is secured to the door jamb 10. Coimter sunk wood screws are preferably used for this purpose. The cars 1% are bent at right angles to form top and bottom members 18 and 20. A front cross member 22 serves to connect the top and bottom 18 and 20 for forming a rigid member to support the mechanism of the door check. The ends of the top and bottom 18 and 20 extend toward each other as indicated in dotted lines in Figure 1 whereby they form a slot 24.

Pivoted to rivets 26 or the like is an arm C comprising side members 28, a cross connecting member 30 and a flange 32.

A rivet 29 extends through the arms 28 and has rotatably mounted thereon a wheel 33. The wheel 33 has on it a resilient bum-per roller 31 of suitable material such as rubber. The flange 32 is connected by a spring 3% to a rivet or the like 36 extending from the top to the bottom of the member A.

The member B comprises a pair of attaching cars 38 which may be secured to the door frame 12. A cardboard shim 4.0 is inserted between the member B and the door frame 12. The cars 38 are bent to form top and bottom members 40 and 42.

For covering the front and sides of the member B and thereby forming a socket I provide a strip of metal comprising the curved portion 44 and a comparatively fiat portion 16 extending between the cars 38. A portion 48 of the strip extends beyond the cars 38 and is provided with a doubled under bead 50.

A rivet or the like 51 extends from the top 40 to the bottom 42 of the member B for holding the parts in assembled position and this ivet has a further object as will be later disclosed in the specification.

A night hook D is provided with ears 52 which extend through openings 54% in the top and bottom 40 and 42 of the member B. The hook I) is in this manner pivoted to the member B and is provided with a hook portion 56 s LEM adapted to engage the edge of the cross front member 2:2 of the member A and be positioned in the slot 2% as illustrated in Figure l. This hook may be utilized when it is desired to lock the door for the night.

Figure 4e illiiistrates the check mechanism oi. my structure as when the door closed. The hook D is illustrated as being hooked for the purpose of locking the door in closed position. This hook may be unhooked as illustrated in Figures 5 and When the door 12 is opened as indicated by the arrow 58, the socket tori-lied by the strip of metal ltl will move the bumper roller 31 to the position illustrated in lfigure In this position the sln'ing i so l acro1-ts the center oi? the rivets w-iereby the roller 31 will be held in this pee on igu-re by the spring 3i. This sets the roller ill position to be actuated'by the door wh n closed.

hen the dooris vi ily closed as illustrated in F'g'ur the head 50 will engage the roller fill i he; the arm Clo move in the direction of tne arrow (it); Zhc spring 34 will then have passed across the pivot center 26 whereby the roller 31 is caused to enter the socket formed in the member 15. However, violent closing of the door produces enough movement of the door in the direction of the arrow to cause the rivet 51 to engage the roller 31 as illustrated in dotted lines in Figure 5 and the roller is caught between the curved portion :8 of the socket member B and the rivet 5-1 thereof and its further movement in the direction of the arrow 60 is prevented. The resiliency oi the rollertll there upon acts to cause a rebound ot' the door 12 and in rebounding, the edge 64 of the socket member B will again set the roller 31. This will continue until the motion of the door 12 has been su'tliciently checked to allow the roller 31 to pass the rivet 5i before the roller can. be caught between the rivet and the bead. 50. This positi-on'is il' trot-ed in Figure (l and the arm C will continue to move in the directii-n-i of the arrow (50- whereby it engages in the socket of the member 13 and the spring 34- tends to close the door and maintain it in closed position.

From the foregoing description it will be obvious that I have provided a'device which actually checlie the movementof the door and causes it to rebound until its momentum has been reduced to a point where the door will not slam when allowed to close. i

In operation, it a person gently closes the door the roller 31 will immediately enter the socket member 16 and maintain the door closed but violent closing of the door will causea re'bound and the number of rebounds will depend on the violence with which the door has been closed.

It will be obvious'that my check can be used on all types of doors and will accomplish the same result. I have illustrated it as being attached to a screen door but I do not wish to be limited to its use on screen doors only.

Some changes may be made in the construction and arrangement of the parts of my device without departing from the real spirit and purpose oi? my invention, and it is my intention to cover by my claims, any modiiied forms of structure or use or mechanical equivalents, which may be reasonably included within their scope.

I claim as my invention:
