To all whom it meg concern: 7

Be it known that I, ALEXANDER RIsrEL, a citizen ofthe United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful. Door Check and Holder, of which thefollowing is a specification. p H r The present invention relatesto improve ments in door checks. and holders, the present invention being an improvement upon the door check andholder set forth in my Patent No. 1,053,222 granted February 18, 1913, one object of the present invention being the provision of a lug carrying means for properly gripping the upper end of the casing to position the lug properly to be abutted by the resilient abutment of the door connecting arm and to hold and prevent the accidental closing of the doorafter once positioned.

With the foregoing and other objects in view which will appear as the description proceeds, the inventionresides in the combi nation and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of whatis claimed Without departing from the spirit of the'invention.

In the drawingsFigure 1 is a front elevation of the complete door check and holder with the jointed ,arm I removed. Fig. 2 is a top plan view of the complete door check and holder. Fig. 3 is a section taken on line 3-3 of Fig. 2. Fig. 4 is a section taken on line 4-4 of-Figp3. Fig. 5 is a section taken on, line 55 of Fig.3. Figs. 6 and 7 are detailvie'wsof a portion ofone,

of the jointed arms carrying the anti-frictional abutment for engaging the cover lock. Figs. 8 and 9 are detail fragmentary perspective views of cooperating portions of the clamping band and actuating means for gripping the open end of the casing to hold the cover securely in place.

Referringto the drawings, the numeral 1 designates the casing of the door check and holder, which is provided internally and intermediate of its ends with the interior screw threads 2 for the reception offthe partitioning disk 3. The spindle '6 projects through the disk 3 and is keyed to the exteriorly screw threaded member 9 mount ed for movement in the spiral groove 11 of v Application filed December 5,1913. lSerial No. 804,922.

Specification ofLetters-Patent. atent O 3, 1914 the plunger 12. i A vertical slot 21 is formed in the'circumferential wall of the plunger 12 and engages or fits'upon the pin 22'carried 1n the casing 1, thus locking the plunger 12 against rotation so that" as the stem 6 1s oscillated, the member 9 will impart a vertical'sliding movement to theplunger 12,

the spring 21 acting as a cushioning means for the ,plunger'in its descent and also assisting-in the ascent of the same.

The I spring-26 is connected to operate the stem, 6 throughzthe sleeve 29 which is disposed for oscillation within the central openmg 30 of the disk cover 31, said cover 31 being providedwith the rim orfiange 31 which fits snugly within the upper end of the casing 1 and thus sealsthe same. this means, thesleeve 29 may be independent of the. spindle 6, and also the cover 31. Formed integral with the sleeve 29 is a disk 32Wl110l'1 is adapted to fit above the; cover 31. the same being provided with. plurality of recesses 33 inits periphery. The

reduced end 6':'.Qf the spindle 6 has detachably connected thereto by means of the split clamping end 34, the inner arm 35. A lug 36 is formed integral with the arm 35 and h as pivoted-i therein, a pawl 37, whichis normally heldby its spring 37 in engagement .with the periphery of the disk 32 so as to, when "thejarm35 is'moved in the directionfof the arrow Fig. 2, rotate the disk 32 and thus place the spring 26 under tension. H

lug 38 isformed integral with. and projects from the periphery of the split clamping band 46 at one point thereof, and is disposedto cooperate with the abutment 39, which in the present instance carries the anti-frictional roller a so that when the arm 35 is moved to a position to hold the door open, theroller will bepositioned upon the opposite side of such lug 38 to that shown in Fig. 2, and the arm'will thus be, locked against movement. The pin 39 is carried by a block 41 disposed for sliding movement within the casing 42 formed in the arm 35 and covered by the plate 40. A spring 43 is disposed therein to normally hold the block 41 and the roller a toward the periphery of the cover 31. 1 By, this means, when the roller a is forced in engagement with the lug 38 the same will roll thereabout and thus depress the spring 43 asthe block 41. is moved outwardly, said spring snapping the same in behind the lug 38 and thus looking the parts in the desired position with the door open.

The adjustable arm 4% is as usual pivoted to the outer end of the arm 35.

A head or rim e5 forms a limiting means for the clamping band 4:6, that carries the lug 38, and said band has formed integral therewith, the two ears 47, recessed upon their outer faces as at 48. are apertured for the reception of the clamping bolt 50, which binds the two arms or links 51, relatively to the ears 41-7, the arms 51 being provided with the rounded projections 52 for registrationwith the recesses 4L8, and so that when said arms are pulled downwardly through the instrumen tality of the bolt 53, the link 54, and the adjusting member 56, the ears e7 are forced more closely together and the band 46 is clamped more firmly upon the casing. The member 56 is provided with the projection 55 to which the link 5%is secured, and has its socket 57 embracing the cylindrical boss 58 carried by the casing. A screw 59, having its head 60 accessible is mounted in the member 56 and limits the upward movement of the member 56 relatively to the boss 58. A spring 61 is provided and has its terminals, which normally separate, connected to the ears 4:7 to assist in opening the band 46.

The lower end of the member 56, is in the form of a knob to permit the easy movement downwardly of such member to more rmly clamp the band 46, after the door check and holder has been' installed, the screw 59, being thus adjustable with a screw driver to hold the member 56 in such desired position.

What is claimed is: i

l. A door check and holder, having a supporting casing, a split clamping band surrounding the upper end of said casing, adjustable means pivoted to the band and connectedto the lower end of the casing for These ears l7 7 regulating the tension of the clamping band, a fluid cushioned and spring actuated means mounted in and exteriorly of the supporting casing, a folding arm connected to the latter means, and cooperable locking means for the folding arm carried by the band and the folding arm. v V

2. A door check and holder, having a supporting casing, a spring actuated folding arm journaled in the supporting casing, a clamping band surrounding the upper end of the supporting casing, manually operated means for adjusting the band and looking it in clamped position, an arm holding lug carried by the band, a resiliently mounted abutment carried by the folding arm for coaction with the lug of the band to lock the arm against the tension of its spring, said manually operated means including a cam mechanism operably connected to the clamping band, a slidable operating member connected thereto and to the supporting casing, and means'for locking said operating member in clamping position.

3. A door check and holder, having a main supporting casing provided with a stud at one end, a folding arm mounted upon the supporting casing for swinging movements, a spring for opposing the move ment of the arm in one direction, a clamping band surroundingthe supporting casing, cotiperative means carried by the band and arm for limiting the movement of the arm in one direction, a pivoted wedging member, connected to the band, and an adj usting and operating member for the wedging membermounted upon the stud of the supporting casing.

In testimony that I claim the foregoing as myown, I have hereto afiixed my signature in the presence of two witnesses.

I ALEXANDER RISPEL.
