Specification of Letters Patent.

Patented July 27, 1915.

To all whom it ma concern:

Be it known that I, Jon-N GERARD, a citi zen of the United States of America, resid ing at New Britain, county of Hartford, State of Connecticut, have invented a new and useful Door Check and Closer, of which the following is a specification.

My invention relates to a door check and closer, the object being to provide a very simple and inexpensive construction, especially useful in connection with screen doors or other light doors.

The object of my invention is to provide an inexpensive simple and eiie'ctive construction.

In the drawings: Figure 1 is a plan view of my check and closer as it would appear in place. Fig. 2 is a vertical section showing certain parts in elevation. Fig. 3 is a horizontal section on the line -38, Fig. 2. Fig. 1 is a horizontal section on the line M, Fig. 2. Figs. 5 to 7 inclusive are detail views. Fig. 8 is a detail view of a modification.

1 is a cylinder which contains a checking piston 2. 3 is a removable cap at one end of the cylinder. 4 is a spindle passing through the cylinder 1 and seated at its lower end in a suitable bearing in the bottom of the cylinder. The spindle 4; has a bearing in the upper part of the cylinder which is extended upward to form an integral sleeve-like extension 5 which may have the usual packing gland 6. On the outer side of the sleeve 5 are one or more vertical ribs 7 7 which form spring holding abutments.

8 is a helical spring having its inner end sharply turned to form a hook 9 to engage one of the abutments, for example, the abutment 7, see Fig. 8. The outer end of the spring 8 is curled outwardly to form a hook 10.

la -Mare arranged to be secured to the door. The piston 2 is connected to the spindle 4 eccentric'ally, as by means of a link 17 which has at its inner end enlarged on cular passage to surround the spindle loosely One side of the lower part or the spindle is provided with a groove 18 having an inclined bottom. The eccentric proper comprises the eccentric member 19 which is formed at its back with a key 20 adapted to fit in the groove'lS when the parts are assembled as shown in Figs. 2, 3 and 1. The eccentric 19 is inserted in place when the spindle is turned in a direction opposite to that shown in Fig. 2. hen in position a cotter pin 21 may he slipped through a hole in the part 20 and a corresponding hole in the spindle at in line therewith, see Fig. 2.

In the modification shown in Fig. 1 1 provide an eccentric 22 which fills the circular opening in the link 17 said eccentric 22 having a shoulder or flange 23 to keep it in place while the parts are being assembled. In this instance the spindle 1 instead of being provided with a groove 18, is provided with a squared portion 18 designed to fit. into a squared passage in the eccentric block 22. The lower end of the spindle & may be somewhat reduced as at 1* and the step in the bottom of the cylinder may be made of a size to receive this reduced end of the spindle.

The checking device may have the usual valved by-pass which is only conventionally shown herein. The piston may have the usual ball check valve indicated at 24, Fig. 6 to permit the piston to move back freely when the closer spring 8 is being wound up.

25 is a cup shaped cap arranged to slide over the closer spring 8, one side wall of the cupped cap being provided with a slot to permit the outer end of the spring adjacent the coiled portion 10 to project outwardly to be engaged by the pin 10. This cap may or may not be employed, as desired.

The parts described may be easily and cheaply manufactured and when assembled constitute a light weight and inexpensive controlling device for doors, particularly useful in connection with screen doors or other light doors. The spring 8 may be very easily reversed without the use of any special tools whereby the device may be apwith the outer end of the spring.

2. In a door check and closer, a checking cylinder, an extension thereon, a checking piston arranged to reciprocate therein, a'

spindle extending diametrically across said cylinder, an eccentric connection between the spindle and the piston, a reversible closer spring mounted on top of the cylinder and anchored at one end to said extension, a lever arm carried by the spindle and detachably connected directly with the outer end of the spring, said spring being of the helical type with the inner end abruptly bent inwardly to engage said extension, the outer end being bent outwardly to be engaged by the lever arm.

3. In a door check and closer, a checking cylinder,-an extension thereon, a checking piston arranged to reciprocate therein, a spindle extending diametrically across said cylinder, an eccentric connection between the spindle and the piston, a reversible closer spring mounted on top of the cylinder and anchored at one end to said extension, a lever arm carried by the spindle and detachably connected directly with the outer end of the spring, said spring being of the helical type with the inner end abruptly bent inwardly to engage said extension, the outer end being bent outwardly to be engaged by the lever arm, said lever arm having a rigid depending extension for engaging said outer end of the spring.

4. In a door check and closer, a checking cylinder, an extension thereon, a checking piston arranged to reciprocate therein, a spindle extending diametrically across said cylinder, an eccentric connection between the spindle and the piston, a reversible closer spring mounted on top of the cylinder and anchored at one end to said extension, a lever arm carried by the spindle and detachably connected directly with the outer end of the spring, with a groove in the side of the spindle into which said eccentric connection projects and is detachably held.

5. In a door check and closer, a checking cylinder, a checking piston arranged to reciprocate therein, a spindle extending diametrically across said cylinder an eccentric connection between the spindle and the piston, a reversible closer spring mounted on top of the cylinder and anchored at one end to an extension therefrom, a lever arm carried by the spindle and detachably connected with the outer end of the spring, with a groove in the side of the spindle in which said eccentric connection is detachably held, said eccentric connection including an integral key arranged to fit said slot.

6. In a door check, a cylinder, a piston therein, a spindle extending into said cylinder, an eccentric, a recess in the side of one of the last two mentioned parts in which the other part stands, the shape of said recess and the part therein preventing one part from turning independently of the other, and an eccentric strap connection between said piston and said eccentric.
