DOOR CATCH.
Application filed June 9,
To all whom it may doncem: v,
Be it known that I, LEONARD W. STEWART, citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented new and useful Improvements in Door Catches, of Which the following is a specification.
My invention relates to door catches of the type adapted to be tripped into operating position by the closing of the door and to resiliently hold said door closed, being automatically reset when the door 'is opened. Door catches of this type have been found to make a loud report on being brought into operating position, which at times would become annoying to individuals.
It is the object of my invention to provide a neat, sturdy door catch that will operate' efliciently with a minimum of noise.
My invention is illustrated in the accompanying drawings 1n wh1ch Figure 1 is a plan view showing the door catch in open position prior to being snapped into closing position by the closing of the door R v j Fig. 2 is cross sectional plan view showing and the e resistbutter 6 seated in the recess h o ance spring H. a Referring now to the drawin sz A crescent shaped operating even A comprising parallel arms aIandltliffspaced apartby rubber buffers 12 b is fulcruriied at c to stamped in one piece from sheet metal and cured to a suitable door frame P,
the supporting bracket C whichin turn is se- The supporting bracket C'is preferably comprises in detail the side portions (2 and 0 each having a flange d d by which said frame bracket issecured to the door screws e, e.) The back portion 0 extends between the upper part of the side portions 0 and 0 and 15 provided with a lug c to whichis secured one end of a coiled spring S, the other end of said spring being'isecured to a pin 0? secured between th armsa and a of the operating lever A. A leafspring H is secured to the back portion 0 of the bracket C by the screw 71, and is curvedto form a recess hf to leaye" catch" s;-

It will'be seen-.from the drawings the th coiled sprin S is so secured and positioned 3 racket C and crescentshape'd'opf between the within the scope of the claims.
door catchbomprising' an arm fulcru id spring during said t gOPer In combination with a d 2 1523. Serial No. 644,295.
the lever A is brought into open position by the opening of the door the spring S will operate to keep the lever A in open position, said lever being limited in its opening movement by the back 0 of the bracket C. When the door is swung to closed position it trips the bufler b bringing the spring over the dead center line with respect to the fulcrum 0 causing it to draw the butter 6 into contact with the door thereby holding the door in closed position.
Because of the fact that a substantially strong spring is required to hold the door in closed position, the tendency of the device is to make a loud report when the catch is tripped. To obviate this loud report the end it of the spring member H is so positioned as to contact with theunderside of the buffer 6 to form a resistance to the lever A when the, spring S is passing the dead center line after the catch has been tripped, thereby materially reducing thesnapping effect of the buffer 5 on the door. When-the-butfer of my invention, all of whic I claim as my invention and desire cure by Letters Patent of theUnit d 1, In combination with a sprijn 1T0. a bracketfand a spring disposed betweenis'a-id I bracket-and saidarm, said-arm "adapte be trippedinto operating position by 'th' tion. of a closing door and held thereto, said spring, means for resisting the-actio f prising a bracket adapted to r 6" contacts with the door the butter 12 has the devicewithoutdepartinglfromftlie srgritv are elaime. a
means for so checking the force exerted by said spring as to break the blow of the arm member upon the door.
3. In combination with a spring actuated door catch comprising an arm fulcrumed to a bracket and a spring extending between said arm and said bracket, tending to swing said arm toward the limit of its movement in either direction, a resilient member secured to said bracket for resisting the move ment of said 'arm.
4. In combination with a spring actuated rename door catch comprising an arm fulcrumed to a bracket, and a spring disposed between said bracket and said arm, said arm adapted to 15 resist said arm during said tripping opera- 20. tion.
In testimony whereof I have hereunto set my hand.
