SCREEN-DOOR CHECK.

Specification of Letters Patent.

Application filed July 21, 1914:. Serial No. 852,274.

To all whom it may concern:

Be it known that I, ALBERT A. PAGE, a citizen of the United States, residing in the town of East Haven, county of New Haven, and State of Connecticut, have invented certain new and useful Improvements in Screen-Door Checks, of which the following is a full, clear, and exact description.

This invention relates to door checks, and more particularly to checks for screen doors, and other light doors.

The primary object of the invention is to provide a simple, reliable and inexpensive door check of the pendant type, wherein a suspended buffer on the door is thrown by centrifugal force as the door closes into contact with the jamb, after which, as the door rebounds, the buffer swings inward to clear the door jamb, and permit the door to close with decreased force. -More particularly, it is aimed to provide a door check having improved means for mounting and limiting the movement of the buffer hanger, which means is so formed and arranged as to permit the free swinging movement of the bufier hanger. The buii'er hanger may be in the form of a straight rod, which has'no binding contact with the door, or other part.

To these and other ends, the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

In the accompanying drawing, Figure 1 is a fragmentary perspective view of a door equipped with a door check embodying my improvements; Fig. 2 is a side elevation of the door check; Fig. 3 is a rear view of the check, showing it detached from the door; and Fig. 4: is a section on line l1 of Fig. 3.

Referring to the drawings, the improved door check is shown as comprising a hanger 10, secured to the door 11, by means of an in closing member-or cap 12, and screw 13, and carrying at its lower end a buffer 14. The hanger 10 preferably consists of a straight metal rod, or heavy wire, having an eye 15, at the upper end thereof, supported on the screw 13 within the cap 12. The screw 13 not only secures the cap to the door, but also serves as a pivotal support for the hanger. The side wall of the cap 12 is of such width 0: depth that when the hanger is engaged with the screw 13 inthe outermost part of the cap, the bufi'er will swing clear of the face of the door without the necessity of bending the hanger.

In order to hold the hanger 10 permanently in the proper position relative to the cap, the clearance opening l2 'in the lower portion of the cap, through which the hanger extends, is formed only in the outermost portion of the cap, there being a shoulder 16 arranged at the inner side of said opening to prevent the eye 15 from working inward in the cap. In this manner, the hanger is efiectively prevented from binding when the device is in use. The shoulder 16 formsa stop for the hanger, which prevents the buifer from contacting with the face of the door when the hanger is disposed vertically. In any case, the arrangement'is such that even if the bufier does contact with the door, the device is prevented from binding, because the upper end of the hanger cannot be moved inward substantially beyond a plane passing. through the center of the buffer, and parallel to the face of the door; v i I The clearance opening 12 in the outermost part of the cap rim permits the hanger to oscillate about the axis of the screw 13, but at the same time limits its oscillatory movement in both directions. The hanger is normally suspended vertically, and the clearance opening permits a slight swingmg movement on both sides of a vertical plane, passing through the point of suspension and perpendicular to the face of'th'e door. I

In order to fix the cap 12 against angular dislocation, the rim thereof may be pro- Patented Nov. 1'7, 1914.

vided with spursfllQ adapted to penetrate the wood of the door.

When the door is forcibly closed, the

hangerfand the buffer will be swung outward by centrifugal force so that-the buffer will strike the door jamb 17 as indicated by the dotted lines in Fig. 1. As the door bounds, and is slowed down, the hanger gradually moves back to its vertical position wherein the buffer clears the door jamb and permits the door to close. The

swing of the hanger is effectively limited'by the slot in the rim of the fastener cap, and said cap suspends and guides the upper end of the hanger for easy movement about the pivot. By having the fastener cap deeper than the radius of the buffer 14:, as shown,

and confining the straight buffer hanger in a shallow slot or opening in the outermost part of the cap, there is no binding against the door at any point, and therefore a straight hanger may be employed with very good results. The device may be very readily applied to the door by forcing the spurs 12 into the wood at the proper point with the clearance slot lowermost and the shank 1O suspended from the cap, after which the screw .13 is screwed through the outer wall of the cap and through the hanger eye to fasten the parts securely to the door. 1 I 1 The cap and hanger are permanently fastened togetherindependently of the attaching screw in such a: manner that said parts,

although freely movable relative to each.

other, cannot, at any time, become entirely separated; This is a great convenience in packaging and selling'the check, and also iir applyingthe same to the door. In the form 'shown,'this end is attained by making thejeye 15 larger than the clearance slot 12 so that the hanger may be suspended from within the cap without falling out of the latter. Moreover, in the form shown, the

capis provided with shoulders 18, which, whenthe hanger is so suspended, engage the under part of the eye, andhold the eye injapproximate alinement with the screw opening in the cap, so that the fastening screw may bereadily entered. through the hangereye. 1 The deviceis assembled by inserting the end 19 of the hanger through the clearance slot, from the inside of the cap, then placing the buffer on the lower end portion of the hanger and upset-ting the end 19 of the hanger to retain the buffer permanently on the'latter, a washer 20 being interposed between the buffer and the enlarged lower end of the hanger, if desired.

The buffer is shown as comprising a disk, freely rotatable on the hanger, but I may use a ball shaped buffer, or one of any other appropriate shape.

Without limiting myself to the construction shown, I-claim:--

1. A screen door check, comprising a buffer, a straight hanger therefor, a deep fastener cap for the hanger, and means for suspending the hanger'from the cap at a distance from the door at least substantially equal to the radius of the buffer; substantially as described.
