DOOR-CHECK.
SPECIPICA'I'ION' forming part of Letters Patent No. 372,034, dated October 25, 1887.
Application liled Jnly 21, 1887. Serial No. 244.913.
1 0 all whom it 7nay; concern! Be it known that I, GEORGE H. LUSK, a ei ti.- zen of the United States, residing at P0111011a, lntna1n county, Florida, have invented oer tuin new and nseful Improvements in Door Cheeks, of whieh tl1e following is a. specificatien.
This invention relates, generally, 10 door bolders 01 checks employing two members, 21 shonldered head and an engagingspring, that are eacl1 mounted independent of tl1e other, one 1nen1ber seen red toa fixtnre and tl1e other to 11 movable part and adapted te be moved into contact with the fixed member, te be en gaged tl1ereby and tenq orarily 110111 tl1e 1novable part aganst aeeidental disengagement.
The present invention consists in 1111 1111- proved strnetnre wl1ereby tl1e operation of the doonel1eek is rendered more effeetive.
In the aeeompanying drawings, illnstrating a practical embodiment 01" tl1e improved doorel1eek, I have shown one n1ember-the engaging-springapplied te easing, sneh as a door-knob, and tl1e otl1e1; membertl1e sl1oul dered studapplied to 1111 arn1 adapted te be seoured to the wal].
In said drawings, 'Fignre 1 is an elevation i1- lnstrating a. door provided with a doorl1andle containing tl1e engaging-spring 111111 the shoul dered stad seeured te tl1e wall adjacent to tl1e door. Fig. 2 is a section of the door handle 01 knob and its spring 211111 en e1evation of the shouldered stud engaging the same. Fig. 3 is 2111 e1evetion, partly in seetion, of the shou1- dered st11d 211111 its arm. Fig. 1 is 2111 elevation of the retainingspring,its supporting eore and. casing. Fig. 5 is a view of a portion of the spring, andFig. 6 is a seetional elevation of a modified form of the casing eontaining the re tainingsprin The door handle or knob A, exeept in the particulars hereinafter speeified, is of the ordinary form, adapted te engage with the spindle 30 of the ordinary doorl1teh, and eapable of being rotated to unla.teh tl1e san1e, 211111 whieh knob is hollowed 01 1'0rmed ef a easing, 11, l1aving en opening, 11), in the center of its face of a size to permit tl1e shonldered stad B to pass throngh tl1e opening into the casing. 111is easing 1'01111s a bolder l'or oontainng a. coiled engaging-spring, 12, that is bent into eircular form, as shown in Fig. 4, to provide (No model.)
21 central opening ortl1e passage of tl1eshonldered stud B. Asiswell understood,ihespring 12 t-hns forn1ed provides a yielding ring, w111e11 wili permit tl1e ready insertion of tl1e head of the stad B tl1rough it until it eneireles and grasps it aronnd tl1e narrowed portion of its shank 14. just in rear of its head. In order to permit this ciren1ar spring 12 to yield it must be so snpported as to permit its ready expansion diametrioally to allow tl1e passage of tl1e head of tl1e stud tl1rongl1 it. '1l1is is accomplisl1ed by providing tl1e cirenlarspring with a Gore, 15, lying witl1in tl1e eoils of tl1e spring. This Gore may be of anyfor1n so 1e1 1g as it will support the Spring and allow it to expand and contract. It is preferably for1ned 01 a split ring, 21s t11is structnre pern1its tl1e forrning of the 0011 of the spring independent thereol, so that it may be inserted over the eore. '111e opposite ends of the cols, instead of being 01 tl1esame size as these lorming tl1e spring, are made 11111011 smaller, as at 22, Fig. 5, for the purpose of allowng tl1e said small 0011 to tightly grasp tl1e core. In order, also, to 0011- fine tl1e opposite ends of the 0011 togetl1er, and thus preserx e tl1e circnlar form of tl1e spring, tl1e Gore 15 is provided witl1 projections 9, of 11001: or other shape and sitnate in close proxin1ity to the split end of the ring, and in practiee a eonple of eoils of eael1 end of tl1e spring, together with tl1e small eoils 22, will De eenfined between tl1e said projections.
The spring 12 and its oore 15 are kept in a eentral position witbin tl1e easing 11 by pro viding one or more projeelions, 8, extending from the eore against the side of the easinm The projections 9 n1ay also be of snfiioient length te act in conjunct-ion wit11 tl1e projections 8 for the same pnrpose. Ribs 7 (see 1ig. (1) may also be provided on tl1e walls of tl1e easing, s0 as te lie between tl1e eoi1s of tl1e spring 12 and to beer apen oppositie sides of tl1e Gore, and t11us prevent it from shifting its position in any direetion, bnt permit the spring t0 expand and contract.
It is obvions that the ribs 7 might be of sncl1 8, and vice versa.
sl1ape as to obviate tl1e use of the projectiens lbeshonldered studB is adj ustabl y 111011 nied in en arm, 16, so that tl1e positien of its head may be fixed to snit tl1e angle at whiel1 the door 01 ether n1ovable part in swinging wi1l
