Application led April 11,1910. Serial No. '554,656.-

' Beit known that I, WILLIAM K. HE/NKY; a citizen of theUnited States, residing 'atv `New Britain, county ofHartford', State of Connecticut, have invented certain new anduseful Improvements in Adjustable Door- Stops, of `which the following is a `full, clear,

and exactv description. y

"of a door closer ofthe conventional type fitted with my' improyed adjustable stop, and showing the levenarni in approximately the position in which it stands when the door 'to whichthe apparatus-is applied is closed.A Fig. 2 .is a side' elevation of the .same parts,l

lthe arm/being shown as engagedby the stop.

' Fig. 3 is'aiilend elevation of 2, looking fromfl'eft to right. Eig. 4 is a longitudinalsectional vview of certain-details. v

l represents lthe cap portion of a closer ,case/of conventional'form, said capbeing 1,. ai' in outline and mounted onA top of the\ cylindrical port-ion 2 .of 'said case. Projectl' fing upwardly through thecapl is a central shaft. 3, upon -Which is mounted a lever 4. VIn this particular instance, the lever 4 is connected by a dog 5. to a spring. driven sleeve, ofA which sleeve, AG is a-flanged portion. The dog-*f5 takes into notches of.the.

.-.iange 6 of .thefsleevef and the spring, or equipment means 1 (not. shown) operates to movethelever arm 4 inv one direction. Thissprin,g-impelled movement of' the lever j 4 isin la vdirection to close' the door, said lever 4 normally standing, when the door is closed,"`

in `approximately the position lshoigvn in Fig.j1. 1 7 is a strap encircling the cap, said strap bearing thereon avstop lug 8, over which the lever arm 4 may swing. The strap 7 is ca. l p l Y Witnesses:

- pable of adjustment around the cap '1, suitable nieansbeing providedto lock thesame fin place. Inthe present instance the strap 7l is' 'divided ai one' side,4 meendebi-ng co" g,

from the stop.. 1 1 .is the spring therefor.,

I n the resent instancethelatch member A.10 has la s iding-bearing'in a sleeve 12,1 ipon which the dog 5 is mounted.- The spring lat-ch 10l is` preferably provided with an inclined bearing face, and its distance from the axial center' of the shaft or spindle 3 is -suchtha't said latch willl he obliged to ride over the stop.8 when -the lever has been swung suiiciently far in a direction tdWard saidstop. The stop shouldv be adjusted at such a position that `it will engage the latch 10 when they door stands ajar tothe desired degree. The tension of the spring l1 is' -sufficient to overcome the tension of the closer spring when the latch 10 Yis-back ofthe stop^-8..

When it is desired to'close the door. from the stopped position, "a slight manual Apressurey against the rear ofythe door is suficient' to overcome the tensioniif the .spring 11, repress'ing the latch 10, whereupon the doormay then close under the action ofthe mechanical closer device.

- What I claim is:

a lever arm mounted tol swing concentrically with the axis of the spindle, a stop adjustably mounted upon the lperiphery of the cap 'portion of the case at its greatestldiameter andarranged lto be shifted to diierent posit-ions angffarly around the axis .of said spindle, in: ns tor' holding the stop in Avarious pos. onsv :if adjustment, said -nieans 'comprising a split strap and al clamping screw for securing the ends o f saidjsplit strap.v a coperating stop engaging member arried-'by the lever arm, one of said stoplOO elements being spring pressed and. yielding.
