Application filed May 10, 1922.

To all whom it may concern:

Be it known that LGEORGE WV. lVLALLORY, a subject of the King of Great Britain and Ireland, residing at Blenheim, in the Prov- Since of Ontario and. Dominion of Canada,

have invented certain new and useful Improvements in Doorchecks, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to door checks of that type designed for assisting the complete closing of the door and the holding of the same tightly closed, said check being automatically reset upon the opening of the door. The present invention is in the nature of an improvement upon the construction forming the subject matter of a prior Patent No. 1,190,313, issued to me on July 11, 1916, and the invention consists in various features of construction as hereinafter set forth.

In the drawings:

Figure 1 is a longitudinal section through the check in set position ready to function in the closing of the door;

Figure 2 is a perspective view of one of the members of the check detached;

Figures 3 and 4 are enlarged sectional views showin the manner of attaching the roller journa s to the frame;

Figure 5 is an enlarged elevation showing the detachable pivotal connection between the rockable frame and stationary frame of the check.

In common with the construction shown in my earlier patent my improved dloor check comprises a stationary frame or bracket A and a rockable member B pivotally engaging said bracket and carrying roller bearings C and D for engaging the door. The member B is so fashioned that, in the position shown in full lines in Figure 1., it will hold the roller C in the path of the door and the roller D so as to clear the edge of the door. A spring E is attached at one end to an inturned ear F on the member A and at its opposite end to an inturned ear G on the member B, being in the position shown in full lines in Figure 1 on one side of the pivot and operating to yieldably hold the parts in the position shown. l/Vhen, however, the door such as H strikes against the roller C, it will swing the member B to shift the spring onto the opposite side of the pivot, whereupon the roller D will engage the outer face of the door and the tension Serial No. 559,738.

of the spring will operate to press the door tightly against the jamb.

The construction as thus far described is substantially that shown in my former patent and the improvements which form the subject-matter of the present invention are as follows In my former patent the rockable member was attached to the stationary bracket by eye rivets. This required first forming the bracket member with flaring or divergent sides and then in assembling, first registering the rockable member with the bracket and then closing the latter a on said member and rivetingthe parts together With the present construction I have greatly simplified the assembly operation by substituting segmental pivot bearings for the eye rivets upon the rockable member, thereby permitting of completely forming both parts and subsequently engaging the same with each other. Thus as shown in detail in Figures 1, 2 and 5, the member B has its side portions B and B formed with open segmental bearings I for engaging the pivot J on the bracket member. The bearin s I have turned flanges K for increasing t eir width and the pivot bearing J is also formed by a pressed flange on the bracket member. The direction of opening of the bearings I is such that the tension of the spring E is always exerted to hold said hearings to the pivots, and consequently, there is no danger of accidental disengagement of the parts.

Another feature of improvement is the manner in which the journals for the rollers C and D are attached to the member B. This is accomplished by forming the journal pins L with grooves M near their opposite ends and by forming the sides of the member B with struck-out and apertured flanges N, the diameter of the aperture in these flanges N is originally large enough to pass over the end of the journal pin L, after which the flanges are flattened down, resulting in the contraction in diameter of said aperture and the firm engagement of the metal side with the groove portion M of the journal. Thus, as shown in Figure 3, the struck out flanges N are initially engaged with the grooved portions of the ournal L, while in Figure 4 said flanges have been flattened down and are securely engaged with the journal.

This feature of construction also simpli fies the manufacture and assembly of the parts in that the rolls and the journal pins may be easily engaged with the member B, while the flanges N are in struck-out position, after which the flattening operation will secure the parts from disengagement.

Inasmuch as the selling price of articles of this character is relatively small, it is obvious that these simple improvements, which lower the cost of manufacture, are of great value in increasing the margin of profit, while the resulting structure is equally good or better than that of my earlier patent.

It will be noted that in engaging the journal pins with the side members B, there is a shoulder on the pin adjacent to the groove N against which the n'iargin of the struckout apertured member rests. This facilitates theclosing in of said member and dispenses With the necessity of using a special tool. l urthermore, when the struck-out portion is pressed in, it will so firmly engage the 'bottom'of the groove as to securely lock the journal from turning.

That I claim as my invention is:

1. A door check comprising a bracket member and a rockable member, the one embracing the other, a struck-out pivot flange on the one member, and a segmental struck-out pivot flange on the other member laterally engageable with said first-mentioned flange.

2. A door check comprising a bracket member and a rockable-member, the one embracing the other, ears on said members forming attachment means for a tension spring, a struck-out pivot flange on one of said members and a segmental pivot bearing on the other of said members, said parts being laterally engageable with each other and the tension of said spring operating to hold the parts in engagement.

3. A door check comprising a bracket member and a rockable member, each formed of pressed sheet metal, and the one embracing the other, ears upon said members, a tension spring engaging said ears, an annular strnck-out flange on one member forming a pivot, and a segmental struckout flange on the other memberv forming a bearing for said pivot laterally engageable therewith, the tension of said spring holding said segmental bearing in engagen'ient with the pivot bearing.

4. In a door check, the combination with spaced side members, of a roller arranged therebetween, a journal pin for said roller extending through the same and through registering apertures .in said side members, said pin having a groove adjacent to the end thereof in which the apertured side member is contracted.

5. A door check comprising a bracket member and a rockable member, the one embracing the other, a pivot on one member, the sides of the other member having open segmental pivot bearings engaging said pivot, and spring means for shifting said rock able member andfor'holding said segmental bearings in engagement with said pivot.

In testimony whereof Iafiixmy signature.

GEORGE WV. MALLOBY.
