lApplication filed May 18, 1910. Serial No. 561,937.

To all whom tt may concern;

Be it known that I, WJLLIAM K. HENRY, a citizen of the United States, residing at New Britain, county of Hartford, State of Connecticut, have invented certain newl and useful Improvements in. Door-Closers, of which the following is a '.full, clear, and exact description.

My invention relates to improvements in door closers, particularly of the so-called t ,7 located in the door-sill, the spindle of the closer operating as 'one of the hinge members for the door.

The inventionis essentially an improvement upon certain features of'construction set forth in my former Patent, No. 833,387 and is useful when such a type of closer is employed upon a single swing door as distinguished from a `double swing `door.

In a singleswin'g door when the door is closed, it rests -at one edge against a rabbety or stop bead on the door properly closed it should same at least slightly, to prevent being swung vopen by drafts. In the construction set forth in my former patent the closer spring will return rectly under the casing but is not so constructed as to hold ythe door against .a stop bead in the manner above described.

Thepurpose of the present invention is therefore to accomplish the above end.- y'

In the accompanying drawings,-Figure l is a verticalsectional elevation of a comcasing 'and' to be press against the l bined sill closer and check for adoor, the

same being approximately full size; Fig. 2 is a plan View with the cover removed; Fig.

3 is av plan view of a detail l; Fig. 4C is a modi` ication of the detail shown in Fig. 3.

It will be unnecessary for me to describe at length the various features of construction constituting the check and closer since in the main all the parts excepting one correspond to the details set forth and fully described in my former patent above referred to. yI will therefore only briefly refer to the same sufficiently topermit that feature of improvement which constitutes the present invention to be fully comprehended.

l represents a housing for a closer spring 2.

3 represents'a housing for the checking element, which, in thislinstance, is a piston type, that is, a closer arrangedI to be.

the door to a position dif 4. The piston is suitably connected to the rotatable spindle 5, the upper end of which projects up through the housing l for the spring so that, its upper end will constitute p f shown) to its closed position. The door is provided at its under side with a shoe 10 having a suitably shaped cavity therein to receive the upper endof the spindle 5. In the particular form shown, the spindle 5 is slabbed off on opposite sides, the flat surfaces, formed by slabbing off said spindle being parallel with the line of movement of the block 6. The recess 11 in the shoe 10 is of an outline corresponding to the outline of the upper end of the spindle and, as shown in Fig. 3, the shoe 10 preferably has two recesses of said outline, said recesses being indicated respectively atl 11-111. It will be observedthatthe side w'alls of these recesses 11-11, Iadapted to engage the flat side walls of the spindle, are tively to the axis of the shoe.

Assuming the shoe l0 were placed upon the lower edge of the door in line therewith, it is apparent that the effect of the closer spring 2` would be to swing the door some- "what past the center since the action of the spring would tend to bring the flattened lsides of the spindle 5 into line with the axis of reciprocation of the block 6. If a stop bead or rabbet were provided upon the door casing to stop the door before 1t hasswung ,past this point, it is obvious that the pres- -ssure of the spring would be exerted in a direction to hold the'door tightly against said stop, in other words, the parts would assume the position shown in Fig. 2, the shoe pressing only against the bearing 8 on that side of the spindle to cause the spring pressure to bezfppliedeonstantly in holding the door closed against the. stop bead. By this very simple'pexpedient,v viz., so relating the angle of connection ofthe shoe l0 tothe pitched at an angle rela-rv spindle 5 that when the door is closed the shoe will bear against only one of the bear- ,ings 8-9, I may successfully employ .my patented sill check in connectionwith a single swing door. I have provided the second recess 11a, which is arranged in a pla-ne oblique to the plane of the recess 11, so that said shoe may be reversible end for end to apply the mechanism to a right or left hand door as may be desired.

vIn Fig. 4 I have shown the shoe 10 provided with only a single recess 11. To make this Shoe reversible merely requires the turn- .ing of said shoe upside down instead of end for end. I regard it preferable to change the angle ofthe recess 11 rather than change the angle of the flat sides of the spindle 5, since the same results can be more readily and cheaply attained by modifying the shoe l10. I appreciate that there are variousyvays that the angle of the shoe relatively to the spindle may besecured, and it should therefore be understood that i-n this present instance I have attempted to illustrate only the preferred construction.

It 1s obvious that closer devices such as l ldescribed may be mounted either in the tread or door sill or in the overhead part of the casing. I have shown the lever as connected to the top of the spindle, and I regard said connection as on top Whether Said mechanism is placed in the sill or inverted and placed inthe overhead part of the casing.

What I claim is:

1. In a sill check, a spindle rotatable in either direction away from a neutral plane intersecting the axis of the spindle, means operating to return said spindle toward said neutral plane from either direction and means for securing a door on top of said spindle at an ang e to said means comprising a shoe arran directly secured to a door and to sai 2. In a sill ed to be spindle. check, a spindle rotatable in said neutral plane either direction away from a neutral plane,

means operating to return said spindle toward said neutral plane, means for securing a door on top of said spindle at an angle to said neutral lane, said means comprising a shoe arranged to be secured to the edge of a door, said shoe having a recess arranged to receive said spindle at said angle.

3. In a sill check, a spindle rotatable in either direction away from a neutral lane, means operating to return said spindlle toward said neutral plane, and a one-piece shoe rigidly securing a door on top of said spindle at an angle to said neutral plane, said shoe being reversible.
