l Avppleatonnled February V23, 1926. Serial No. 89,977.

My invention relates to improvements in door. stops of the strut kind. r The object oi' my invention is lto provide a stop or' this character which shallliave a strut ,which can be readily adjusted asl to length; .the shoe lof o which can bei readily made fromsuitable tubing; which shall have an improved form of yielding spring `for holding the strut in inoperative position; and which shall be provided with means for interlocking the shoe with `the lever in a definiteoperative` position while allowing the a'diustmentv of the shoe on the lever iforchanging the length of the lever. Another feature of importancerelates to a simple member for interlocking the shoe with thev lever or strut and whiclimember is fixed rotatively inrelation to the strut, and is provided with 'lifting'lngs always presented at the sidesof the lever. Y

My invention will be more readily under'- stood by reference to the accompanying drawing in which Fig. 1, is a side elevationof a ldoor stopV constructed in accordancewith-my `invention; 4

Fig. 2, is a kfront elevation of same; Fig. 3, is a fragmentary, vertical section on the lineB- oi' Fig. 2A; Y

Fig. 4:, is a horizontal section on the rline 2li-L of Fig. 3; i

Fig. 5, is a plan view of the looking member in partly i'ormed condition; and. 4 F ig.` 6, is a horizontal section on the line 6-6 of Fig. 1. f o

` In said drawings. 1 represents a door to which the stop vof my invention is adapted to beyattached,- and 2the`ioor with which the y stop is adapted to contact to hold the door kfrom swinging in one direction.

My improved stop comprises a rigid base member adapted to be secured to the door by screws 4. Near the lowerend of the base are a pair oir' rigid lugs 5 spread apart to receive one end 6 of a swinging strut 7 between them. The strut -7`is pivoted tothe lugs 5 to swing up anddown by a horizontal 4pin or Vpivot member 8 which is secured in perforations in the lugs 5 and passes through a per- -foration in the end '6 of the strut 7. At the upper end ofthe base are a second pair o1 vrigid lugs 9`betweenwhich the body `ofthe strut 7 is received when it is swung up to verticalposition, as'sliownV in dottedy lines in Fig. 1. vA U-shaped spring 10 is provided which is received between the lugs 9 and which is formed to clasp the strut and yieldingly hold same, in raised, thatis, inopera-` tive position. The base member 3 is provided with an vopening 11 leading into 'the space between the'lugsv 9 vt0 receive the spring 10, and the opening 11 widened out at the back of the base to receive formed out parts 12 or the springlO lto preventv the `spring moving orward,"and the opening is of such depththat when the base Sis secured to a door the base of the spring contacts the door and the spring is heldfirmly in place. The prongs of the spring are formed between their cndsto clasp the bodyof the lever. The outer ends 14 of the prongs 13 are bent outwardly and enter notches 15 provided in the outer ends of the ,lugs 9. The projections 14 overlapI the lugs 9to aslight extent and retain the springs against removaluntil'the device is secured `to a door. The forming over. of the outer end of the spring to 'provide'the projections 1i provides the prongs with rounded surfaces 16 which permit the rounded bodyV of the strut to enter easily between theprongs. 1 e f o The outer or free end 17 of the body 7 is cylindrical and is provided Lwith an external screwfthread and I provide animproved f shoe 18 or cooperation with the body of the strut to form the complete strut.` The shoe 18fis preferably ormed. :from a piece of tubing, ,the lower end portion of which is Hattened down vand bentoii' at an angle to orin a bottomof the shoe, las indicated at 19. Thel shank 2O of the shoel ,is left tubular and is internally threaded to it on the threaded endl? of the strut body 7. The orrningof the bottom 4of the shoe in .the manner Vdescribed provi des a second' transverse shoulder slipping-,on the iioor.

p The shoe is ad, ustable on thebody of the strut by reasonof the threaded engagement and the strut is shortened or lengthenedffor proper contact withtheffloor by screwing v CTI the shoe up or down, as the casemay be. As the bottom of the shoe is made at an angle to the shank, other than a right angle, there is only one relation of the shoe to the strut whichwill cause the shoe to properly con-y tact with the floor, consequently in shortening or lengthening the strut the shoe must be rotated one or more complete turns. ln'V` n terposed between thetop end of the shank of the shoe and the nut 25.k lt has a central opening 27 which lits freely over thethreaded end 17 of the strut member 7 and'is formed with two vopposite lugs 28 and 29which project into 4the Opening 27. One of the projections (28) is left as formedand engagesin a longitudinal key-way formed thek threaded end l?. The other projection 29 is f bent down and engages in a notch 81 provided in the top of the shank of' the shoe. t 'will be readily seen that the interlocking washer 26 cannot rotate on` the threaded end 17 by reason of the projection 28 engaging in the key-way 30 and that wheiithe projection 2,9

Y' there that the shoe will be held dcnitely in place.

the strut, the nut 25 is screwed-back, the infrom the projection 2 9 and then the shoe is rotated va number of full turns, onel or more, as may be necessary. Then toV secure theshoe the washer is dropped into place, the'projection 29 entering the notch 31 and rthenut 25 is screwed hard down. Besides serving to interlock the shoe with the strut vthe washer 26 has another function. At opposite sides the washer is provided withprojections 32 which are arranged to extendout transversely ofthe strut and provide lugs by which they strut can be' readily lifted by the foot of the operator without the necessity ofrstooping down; yTo prevent these lifting lugsl marring the leather of the shoe in lifting the strut, they are covered preferably by means of a rubbery envelop 33, the lugs beingv enlarged at their outer ends to assist in preventing'the yenvelops being removed). rlhese envfelops may either'be pre-formed and vulcanized and then pushed von the projections and secured by proper cement, or they may be vulcanized in position. These lifting projections are' so related lto the

inner projections

28 and 29 that when the strut is in operative condition they extend transversely of the strut, or, in

yother words, parallel with the door l.' j Y As many modifications of my invention will readily suggest themselves to one skilled When itis desired to adj-ust the length in the art,`l7do not limitv or confine my iiivention to the specific details of 'construction herein shown anddescribed.
