YIELDING STOP Filed May 25, 1931 5 9 f/JwArw RMARBAQH 1 MA 15 W ddommq Patented July 18, 1933 UNITED STATES EDWARD. n; MARBACH, F cnnvnmnnf OHIO- YIELDING STOP Application filed May 25; 1931. Serial No.'539,648:,

This invention relates toa yielding stop, and. especially to an adjustable stop adapted to yieldingly limit the movement of one member toward or awav from another member,

and. isespecially adapted to limit the out-' ward movement of doors. While my invention is especially adaptable for use in connection with doors of motor vehicles and the like it is never the less well adapted for many other uses,hence I do not restrict myself to astop for doors.

My improved stop is of the type comprising an arm, one end of which is pivotally attached'to one member, such as a door frame,

and slidably mounted in another member,

such as the door itself. On its innermost end within the confines of the door is a resilient member, adapted to coact with the inner .surface of the door, to limit its swinging movement' and prevent damage to the hinges.

Such stops have been used in the past, however, but they have been difficult to assemble and have been so constructed as to require the handling of several independent parts, to position the stop on the door. Often the assembly of these parts was diflicult and required considerable skill and time thereby increasing the cost of the article on which they were used andmaking repairs difiicult. The general object of this invention is to provide an adjustable stop member which will yieldingly limit the movement of one membertowand: or away from: another. H

A more specific object is to provide a: stop adapted toiyieldingly limit the movement of one member to or from another member, which stop will be easily and economically manufactured, and so constructed as to comprise a minimumnumber of separate parts, enabling. it to be readily secured in place with a minimum, amount of time and labor.

Other objects of this invention will be come apparent from the following description referring to the accompanying drawing, and the essential and novel characteristicswill be set forth in the claims.

Referring to the accompanying drawing, wherein I show a preferred embodiment of my invention;

Figure 10 is a perspective of a: modified form ofmy improved stop.

Referring again to: the drawing my improved stop is generally indicated at 10, and is shown as-used in conjunctionwitha-hinged member such as, the door 11. In Figures 1, and 2a relatively stationary member or door frame is indicatedzat: 12. Securedto the face- 13' of" this frame is a hinge member 14, to

' which ispivotedby means ofca pivot pin 15 a complementary hinge member 16, whichis,

in turn, secured to the door 11.

My improved stop 10 comprises a rod or bar 20, one end of which is pivoted as at 21 so to-a bracketr22, in: turn secured by suitable bolts or screws 23, to the' door'frame 12. The other end of the bar 20- passes through a restricted opening- 25 in theedge of the member 11, and carries adjacent itsinnermost end a resilient stop or bumper member 26.

The bracket 22. supports the stop member a and is secured to the door frame 12 by suitable bolts or screws 23 as heretofore de-- scribed. This bracket 22 preferably comprises a substantially flat plate 30, the ends of which are folded rearwardly, and then inwardly to a position contacting with the center portion of the plate. Before the plate is bent suitable OpeningsSl and 31aare formed thereimand so located that when the plate is bent or formed the openings 31w overlie the openings 31. Itwill be noticed "that theopenings 31a are smaller than the jacent these openings 31a is bent rearwardly, forming a counter sunk opening, adapted to readily receive the screws 23, which when in place will lie flush with the surface of the bracket 22.

The plate 22 forms a socket or pivot to which the limit rod or bar 20 is pivoted. The rod 20 hason one endan enlargement 32 adapted to fit in' a socket 33 formed between the rear and front p'ortions'of the'plate or bracket 22. The bar 20 extends forwardly from the socket 33 through a slotted opening 34 in the front face of the plate 22. The rod 22 is preferably inserted in the opening 34 before the bracket is formed, and the bracket is thereafter placed in a suitable press, so arranged as to cause the bracket 22 to substantially encompass the enlarged portion 32 of the bar forming a socket therefor.

The resilient stop 26 comprises a truncated cone preferably made of rubber or some simthe outermost edge ilar resilient material, and is so constructed that it may be readily placed in position'on the end of the bar 20, opposite the pivot 31 with a mmlmum amount of eifort,'and when placed in position thereon will be diliicnlt to remove, thereby guarding against inadvertent I displacement. Vulcanized within the cone is a metallic washer or cup 40, provided withajsuitable opening 41 through which the Within the washer is placed a spring 44, comprising. a perforated disc having a plurality of outwardly extending ears 46, adapted to extend beyond mined distance from the face 26. This spring 45 is also provided with a plurality of tapered prongs 48, adapted to engage the serrations or indentations 35 on the-bar 20. v In the form shown, thereare' four sets of serrations 35, and these'sets are oppositely disposed 1n palrs, and would form, if the serrations were continuous, a substantially contmuousthread. However I find it advantageous for reasons hereinafter explained to interrupt this thread.

The construction of the spring member 45 is such that when 'it is the stop 26 and rod 20, it is only necessary to slide the rod through the enlarged opening 36 in the stop. The edges of the'prongs 48 of the spring member 45 will then contact with the face of the rod and engage the indentations or serrations 35. As the prongs 48 are inclinedontwardly from the plate or spring 45, they will readily pass over the serrations 35 when the stop is drawn onto the rod 20, and willact to restrain the stop against movement from the rod.

Whenan attempt is ma'de to withdraw the stop from the rod by merely pulling or sliding it-from the rod, the edges 50 of the prongs 48 of the spring member '45 will enof the disc 40 and serve "to'space the retaining spring, a predeter- 47 of the stop desired to assemble gage the serrations 35 of the rod and the pulling movement will tend to bend the ends 50 of these ears inwardly thereby gripping the rod tighter and coacting with the serrations 35 to prevent theremoval of the stop 26 by such pulling movement. Hence the adequate protection is had against inadvertent displacement by any such movement.

The construction is such that the stop 26 may be removed for replacement. Reference will, now be had .to the diagrammatical illustration in Figure 9, which illustrates the development of the various ears 46 and prongs 48 of the spring 45. t will be noted. from Figure Qthat'the prongs 48 are tapered so that they extend varied distances from the mg outward the greatest distance and the face of the disc 44. The prong 48a extend,

prong 48b extending slightlyless, the prong 480 a like amount less than the prom 48b,

and the prong 48d extends substantiall y the same distance as the prong 48?). This forms a simulated thread, hence when the stop 26 is rotated the prongs 48 will rotate on the serrations 35 the same manner as a nut on a bolt and the stop 26 may be thus withdrawn from the rod 20. t p

heretofore mentioned the serrations 35 l3 do not form a continuous thread. They are interrupted by high. portions55, hence when the stop 26 is rotated the prongs 48 will ento the flattened face 50 of the prongs 48, thereby insuring against inadvertent displacement by, rotation of the stop 26, but at the counterthese high portions 55, likewise the I base 56 of the serrations, is flat conforming same time, permitting the stop 26 to be readv comprises an- L-shaped plate 60, the outer edges ofeach 'arm of the L being bent rear- Qwardly and then outwardly along the inner [Suitable openings 31a are f face of such arms. I v I provided in each arm of the L to enable the heretofore described. Thebrackethowever member or bracket 60 to be readily secured to two adjacent surfaces of the door frame.

From the foregoing description itwill be apparent that I have provided'an improved stop which comprises a'minimum amount of parts, namely two, the rod assemblv and the stop assembly which aro'readilypositioned on a door or similar article, and are so con structed. as to prevent inadvertent displacement an'd yet permit adjustment and replace ment. to be made readily.

Having set forth the principles of my invention, and described and illustrated an embodiment thereof for practical use, what I claim and desire to secure by Letters Patent, is,- I

l. 'A' stop comprising a rubber composition member having an axial opening for receiving a serrated bar therethrough spring means comprising a pair of metallic discs arranged in contact, one disc of the pair having a plurality of prongs bent outwardly and away from the other disc, vulcanized in the rubber member and adapted to engage the serrations of the bar to prevent inadvertent movement between the rubber member and the bar. a

2. A resilient composition stop member having inserted therein a metalic disc provided with an aperture through which an indented rod may be freely passed a second disc substantially in contact with the first named disc and having a plurality of prongs bent, outwardly from the face thereof extending away from the first named disc, wherein said composition completely fills the space between the first named disc and the prongs of the second named disc.

3. A rubber bumper provided with an aperture whereby it may be slid onto a serrated rod, a flanged apertured disc vulcanized in said bumper and through which the rod may pass, a second disc arranged to contact with the first named discand having a plurality of series of ears, one of said series arranged to be embraced by the flange of the first named disc and the other series projecting outwardly from the first named disc and arranged to engage the serrations 0n the rod,
