To all whom t may concern:

Beit known that l, CLARENCE E. PRYoR, a citizen of the United States of America, residing atiJersey City, county of Hudson, State of New Jersey, 'have invented certain new andv useful Improvements in Bumpers, of which the following is a specification.

This invention relates to bumpers.

More particularly this invention relates to bumpers embodying Va plurality of rails, arranged Vin different vertical planes relative to' the car and assembled relative to one another to provide vforresilient resistance in opposition to encountering obstacles effected as a resultant by the combination of the resiliencies ofthe individual rails.

AA further feature of the invention is the provision of mounting means for the pluralitjT of rails whereby the front faces of the rails are maintained normally and when encountering an obstacle in substantial parallelism and substantially in vertical planes.

A further feat-ure of the invention is the provision of improved means for the combined inter-tying of the rails t-o provide for relative vmovement o-f the rails to one another when encountering an obstacle' and thereby give riseto an improved resultant resiliency.

Pursuant to a preferred form of the invention, two rails are located forwardly of and respectively above and below a rearward central rail; the rearward rail is mounted in a pair of spaced clips and the clips are yieldingly and adjustably mounted on the spring horns ofthe automobile or other vehicle whereby the rearward rail is maintained substantially vertical for all positions of yielding of the clips, and the forward rails yare intertied with one another and with the rearward rail whereby in the event of anl obstacle encountering the forward rails aty any location between the spring horns the rearward rail is automatically moved forwardly in combination with the forward rails to increase the resistance of the forward rails in opposition to the encountering obstacle and to present the rearward rail in opposition to the obstacle, such movements being effected with the elimination automatically of all thrusts and strains onthespring horns towards or away from another; and whereby in the event of an obstacle encountering any end portion of a forward vrail laterally of a spring horn, the opposite end portion of such rail operates in combination with the other forward rail'and with the rearward rail and is moved automatically forwardly to there* by increase rcombinedly the resistanceV o-f such encountered end portion of the rail in opposition to the obstacleand automatically eliminating all thrusts and strains on the spring horns towards or away from one another.

Further features and objects of the invention will be more fully understood from the following detail description and the accompanying drawings, in which- Fig. lf is a top plan View of a bumper embodying three rails, two of which are normally'located in advance of the third rail, thev same being mounted on the forward pair of spring horns of any approved type of automobile and arranged pursuant tomy invention;

Fig.A 18 is a central transverse sectional view of Fig. 17; and

Fig. 19 is a detail front elevation on an enlarged scale of the centrally-tying clip.

Referring to Figs. 1, 2 and 5, the particular embodiment of the invention asillustrated in the drawings comf'prises the upper forward 'rail 10, the lower forward rail 11 and Vthe central, rearward rail 12. Such 'l forward rails'lO, 11 may be interconnected centrally by means of the strap 14, having its upper end bent about the upper edge of the upper rail and its lower end bent about the lower edge of the lower rail 11 and Carrying centrally the plate 14a, secured thereto by the vertically aligned screws 14h.

VThe front face of the plate 14a may be mark-ed with a designation of the manufacturer, or to indicate any particular style of bumper or be ornamented by'an emblem or otherwise to suit the fancy of the purchaser.

Such plurality of rails are movably intertied with one another by the opposite end inter-tying means 15, 16. The rails are supported by means of the spaced members 17, 18,I carried respectively by the spring horns,

19, of the automobile or other type of vehicle.

.Each mounting member 17, 18, see Fig. 5, comprises the rail carrying clip 21 formed as a vertical U and having the clearance 22 within which the rail 12 ris received and locked therein by means of the screw 23, bolt or the like. The rearward portion 24 of each member 1,7, 18, extends integrally from the clip member 21, and comprises a flat central upper face 24a and a rearward extension provided with the intern'iediate slot 25 and oppositely disposed fork elements 26, 27. The lower portion 28 of each member 18 is hollowed to .movably receive therein ,the forward pivot member 29, pivoted at its upper end on the pin 30 and at its lower Vend on the relatively long,^ stout p-in 31.

As will be noted in Fig. 5, the retractile coil spring 32 has its upper hooked end 33 'hung' on the pin 30 and its lower hooked end f34 secured to the pin 35 4extending from one f lug 36 to its opposite lug 36, see Fig. 2.

At the upper rearward portion of each mounting member 17, 18 is secured the pin 37 which is removably mounted inthe oppositely disposed fork members 26, 27 and extends across the intermediate slot 25. The eye bolt 38 has its eye 39 lodged on the pin 37 and the opposite eye 40 of the eye bolt 38 is secured to the pin 41 of the pair of pivot lugs 42. The eye bolt 38 is preferably arranged to be adjustable in length by means of the sleeve 43 provided with a continuous threading, say of right-hand turn, meshing with the right-hand threadings 44, 45 on each of the ends of thel separable parts 38a, 38b of the eye bolt 38, see Fig. 5.

Preferably, the pair of pivot lugs 36, 36 for the pin 35, the pair of pivot lugs 46, 46 for the pin 31 and the pair of pivot lugs 42, 42 for the pin 41, are cast integrally with the base member 47, which is secured to the spring horns 19, 2O respectively, by means of the rearward set bolts 48, 48', and locked forwardly by the hooked end 49.

The set bolts 48, 48 are preferably locked by means of the plate 50 having a curvature greater than the spring horn 20 and provided with a circular opening 51, through which extends the bolt 48 and further with a slotted opening 52 through which extends the bolt 48. y

The adjustment of the adjustable eye bolt 38 is attain-ed by removing the pin 37 to free the eye 39 of the bolt 38 and turning the collar 43 to attain increased or decreased spacing of the separable parts 38a, 38b of the bolt 38. By the provision of the righthand threadings 44, 45 of theseparable parts 38, 38h of the bolt 38 any movement of the threaded collar 43 due to vibration, jarring or the like will not cause any variation in the effective length of the eye bolt 38.

.As indicated above, the eXtreme ends of the rails 10, 11, 12 are inter-tied by the interl rail 10 extends for its major portion, substantially rectilinearly and substantially at right angles to the longitudinal center line of the vehicle, but at the oppositely disposed location 53, 53 is bent rearwardly as is indicated at 54 to-ward the respective intertying members 15, 16.' The inter-tying members 15, 16 substantially lie normally in the plane of the substantially rectilinear, central, rearward rail 12. The lower, forward rail 11 is arranged similarly to the upper,

forward rail 10.

Referring to Fig. 3, the eXtreme end of the upper' railvl() is substantially in vertical alignment with the extreme' endof the' centml rail l2 which in turn is in substantially .vertical alignment with the extreme end of the lowermost rail 11. As has been indi cated above, the oppositely disposed means 15, 16 are provided for respectively intertying the ends of the upper rails 10, 11 and the central rail 12 to one another whereby to provide for movement of the rails relative to one .another and to eect in the event of encountering an obstacle a resultant resiliency arising from the combined action of the rails relative to vone another and the elimination of thrusts or strains on the spring horns toward or away from one another.

As one form of such inter-tying means, 15, 16, I provide, as is illustrated enlarged in Fig. 3, the slotted sleeve extending from above the uppermost rail 10 to below the lowermost rail 11, the slot thereof being indicated. at 56T56, and of a normal clearsnes, as is indicated in Fis e, substantially equal to the thickness of any rail 10, 11, 1.2.. Between the central and ythe respective upper ,and lower rails are disposed the spacing and keeper members 57, ses Fg- 3, each comprisingy an outwardly extending `circular apron 58, an inwardly disposed, cireular lock portion 5,9 .connected integrally by the extension 60, see Fig. 8, with the outer apron 58; the extension 60 is substantially the width of any rail 10, 11, 12 whereby there is provided an annular slot lextendinga full circumference excepting .for the width vof the extension 60. lithin such slot 6,1 is locatedthe slotted sleeve 55. On the upper face of each keeper member 5,7 is provided a substantially rectilinear, diametrically extend-ing rib 62 and similarly 0n the lower face Ais provided' a substantially l12 the slot 65 for coaction with the lower vrib 63 .of the upper keeper member 57.

- Similarly, for the lower keeper member 57, I provide the slot 66 at the lower edge ofthe central rail 12 for coaction with the upper rib 62ofA the lower keeper member 57 4and likewise the slot 67 at the upper .edge of the lowermost rail 11 `for receiving` the lower rib .63 of the lower keeper member 57.

,The vtop keeper member 66 corresponds in construction to `the aforesaid intermedilate keeper members 57 and like parts are `marked with .the same reference numbers;

however, the top keeper member 68 extends integrally, as is indicated at 69 for the full diameter of the lock portion 59 4to thereby fill the space within the hollow capxZO three-,ded to the .upper threaded .end .711 ef the hollow sleeve 55; its rib 6 3 on its lower face is received within the slot 72 at the upper edge of the uppermost rail 10.

4The bottom keeper member 73 corresponds in construction to the top keeper member 68 but is of obverse disposition; the rib 74 on its upper portion is received within the notch 75 at the lower edge of the lowermost railll and the lower face 76 ex tends integrally of its lock portion 59, to lill 'the interior of the bottom cap 7 7 threaded to the lower end 78 of the slotted sleeve 55,.

The left-hand inter-tying means 16 correspends construction to the right-hand interftying means 1 5 and like parts are indicated Vby the same reference numbers.

As an additional means for serving as a rail and further coact-ing with the spaced clips 21 and mounting means therefor, including the base plate 53 attached to the .respective spring heres 19., 20, I Provide the rod 48() having thernuts 81, 82 at its opposite ends, see Fig. 1, and passing through the openings 83, see Fig. 5, in the respective base plat- es 53, 53.

In Vthe event of the bumper, shown in Figs. 1 to 5 inclusive, encountering an obstacle say atl the extreme right-.hand free portion of the forward rails 10, 11, the forward railsfwill be flexed rearwardly to the position 1021 indicated in dot and dash outline in Fig. 1, in which action the rearward rail 12 atits rfree right-handV end is flexed to the position 12aindicated in dot andV dash outline, due to the inter-tying means y15. The position assumed by the inter-tying means 41.5 is indicated at 15a. Such rearward flexing of .the aforesaid right-hand parts causes the flexingA forwardly of Vthe left-hand free end portions of the upper forward rail 1() tothe position 101., land similarly v,the lower forward rail 11, and the rearward rail l12 will be flexed forwardly `to vthe position 12by indicated in dotv and dash outline ydueto the intertying means 16, the inter-tying means being moved forwardly to the position indicated at 16h.

Y Asa result of such mutual coactiom'the resilience7` of the rightfhand free endy of the .rails struck by .the obstacle, is increased,

resulting in an increased opposition of the struck rail or rails `to the obstacle. The de- 4grec of increase of the opposing resiliency ,increases with the extent of flexing of the struck rail from normal position.

Furthermore, such coactio-n of the rails with .one another, is effected without any thrust or strain inthe .central portion of the rearward rail 12 and without any thrust icc In the event of an obstacle encountering any rail at a central portion thereof, that is to say between the spaced clips 17 18, by reason of the inter-tying of the front' vrails `with the rearward rail as above described, the front rails recede bodily in a substantially parallel movement toward the rearward rail Vand upon continued recession of the forward rails the rearward rail is brought in vertical alignment with the forward rails to present additional opposition to the obstacle. Such recession of the forward rails bodily causes a corresponding recession of the opposite inter-tying means 15,*16, Without giving rise to any strain or thrust on the spring horns toward or away from one another.

It will be noted that in the event of any rail encountering an obstacle, the impact gives rise to a receding of the rails bodily in addition to the yielding afforded by the extent of receding being dependent upon the resistance of the springs 32, 32, of the respective clips. It will be further noted that upon recession of the rails, by reasonv of the mounting means of the respective clips 17 18 on the sets of parallelly arranged pivotal members 29, 38, the rails are elevated with respect to the spring horns and at the same time the front faces of the rails are maintained substantially vertically.

Preferably, the center rail 12 as shown in Fig. 11, comprises a plurality of rails 89 of graduated increasing lengths extending respectively centrally between and laterally vof the clips 17 18 thereby providing for increased resistance between the clips 17, 18, and also for a graduated increasing resistance against flexing rearwardly when an obstacle encounters either free end portion of the rails, as is indicated in Fig. 11.

For the purpose of adjusting the effective length of the eye-bolt 38, either eye 39, l0 is freed of its pivot pin, by withdrawing such pivot pin thereby permitting change vin lengthy of the eye-bolt as may be desired,

Vparts 38a, 38", whereby when the eye-bolt parts are reasonably close to one another and the collar even if turned for the full length of the threading on one of its bolt parts, engagement with the threading of the other eye-bolt part maintained and uncoupling precluded. yIt desired, one eye-bolt part may be permanently secured to the collar 4:3.

parallel movement of vof the clips 17, 18, and of the rails, an

precludes audible vibrations.

Another modification of inter-tying of the ends of the rails is shown in Figs. y9 and 10, wherein the upper rail 10, as is indicated in Fig. 9, is bent Vat a location indicated generally at 90 rearwardly until such end portion of the rail 10 assumes a substantially horizontal position as indicated at 91. 1n a similar manner, the lower forward rail 11 is bent upwardly at the location indicated generally at 93 and rearwardly until ,such end portion of the rail 11 assumes a substantially horizontal position as indicated at 96. f

As is indicated in Fig. 10,V the central rail12 ait each of its opposite ends is bent on itself as is indicated at 97 to form an eye, preferably located on its rearward flat face. Between the flat `face 91 ofthe upper forward rail 10 andthe eye 97 of the central rail l2 is disposed the spacing collar 98 and between the eye 97 of the central rail 12 and the horizontal flat face 96 of the lower forward rail 11 is disposed a similar collar '99 and the bolt 100 is passed through a suitable opening in the flat face 91 of the upper rail 10, thence through the collar 98, thence through the eye 97 of the central rail 12, thence through the collar99 and thence through a suitable' opening in the horizontal flattened portion 96 of the lowermost rail 11; the bolt 100 is locked and tightened in position by the nuts 101, 102 at its opposite threaded ends.

The inter-tyingy action at the oppositev ends of the rails 10, 11, 12 inthe arrangement shown in Figs. 9 and 10 is similar to that described hereinabove. 'l`he arrangement of Figs. 9 and 10 is simpler in assembly and derives an enhanced resistance provided for by the bending of the vtop rail 10 and,` bottom rail 11.

In t-he modification shown in Figs. 9 and 10, the co-action of the respective rails, and the upward, parallel movement ofthe rails bodily by reason of the parallel pivotal means of the respective clips, is similar to that described relative to the construction with the `relatively flattened face portion 105,'s'ee Figs. .5 and 14, disposed eccentrically beyond the axis of its pivot pin 31 whereby when the rails are free, such faces 105 encounter the upper faces of the base plates 53, 53 respectively, thereby limiting the downward movement of the link members 29 and therewith limiting the downward movement of the clips 17, 18. The adjustment of the eye-bolt 38 as above described, is provided primarily to attain substantially vertical positioning of the-front face of the rearward rail 12,`and likewise of the forward rails 10, 11 when the surface portions 105 vof the respective link members 29, 29 are iii-engagement with'the base members Q53, 53.

"Ifdesired, the pins 31 ofthe respective pivot members 29 maybe replacedby a common pivot rod 31a, see Fig. 12, making a tight connectio-n by means of a spline, key, weld or polygonal cross-section respectively with thel pivot members 29 of the spaced bumper-'carrying clips 21,whereby upon displacement of any portion of any bumper rail and consequent upward rotation of either pivot member 29, the other pivot member 29 is lto like-'extent rotated upwardly by reason of such rigid connection with such common pivot rod `and thereby bringing into simultaneousv action both springs 32 vand re lieving the bumper parts of twisting or bindinv.

Auch commonpivot-rod serves also as atie rod and a barrier. v

1n fFig. 13, I illustrate a modified form of clip for horizontally pivotally carrying one bumper rail 12 or a plurality of bumper rails 12, 89, and comprising a yoke 110 eX- teriorly embracing the rail 12 or rails 12, V89 o'nthe vertical frontal face and horizontal upper and lower :faces and further embracing a. 'bulge member 1-11, the latter being pivoted jointly withA ythe yoke 110 to the common pivot bolt 112 passing through the vertical opening 113 in the clip 24. Upon tightening the Ybolt 112, the bulged member 111 isfforced forwardly into compressional contact with the rail or rails 12., 89, thereby clamping the same with the yoke 110.

In Fig. 14, I illustrate a modified form of spring varrangement for resisting rearward displacement of the bumper rails, compris ing an extension 114 having an opening 116a for attachment to one end of the spring 115; the other end of the spring 115 is hooked in theeye ofthe eye-bolt 116, adjustably anchored on the axle 117 of vehicle. Such anchoring means comprises a hook member 118 and a o o-acting hook bolt 119 passing through an opening '120 in the back plate 121. The` springiholding bolt 116 passes through the opening 122 in the kback plate 121. Asis indicated in Fig. 14 and also in Fig. 15, the openings 120, 122 are arranged on centers spacedfrom one another less than the sum of the maximum radius of thenuts-123',-12r4, respectively of the spring-holding bolt 4116 and the hook bolt 119. Such arrangement precludes turning of the nuts 123, 124 by mutual engagement with one another, under the condition of jarring incident to traveling but upon the spring-holding bolt 1,16 being forcibly drawn rearward to clear its nut 123 from eng-agement with the nut 124. In a similar manner, Athe rearward end of the spring 115 may be secured to the carspring 11721, or any suitable part ofthe car. In Fig. 16, the back plate 121 is offsetat 125 to afford a 'locking shoulder there-at for the nut 123 of the spring-holding bolt 115.

In Figs. 17, 1:8 and 19,-the rail 126 -is formed of a for-wardfintegral portion extending from one free end' to the opposite freeend of 4the rail and is bent forward on itself, the ends `being indicated at 127 128 respectively and providing a clearance 129 therebetween. The front ratil' 130 is located forward ofthe rail 126 and held in the railholding clips 110. The central tying -cli 131 passes over the frontal facefof the 'raiV 130 and over the upper and lower edges of the rail13v0, the rail 126 and its forwardly bent end portions 127, 128, and receives in its 4upper and lower openings the bolt-132 rivet lor )the like, passing ythrough the-clearaiige 129, and thereby locks the ends 21,27,A From the above several embodiments v.of my invention, 'it will'be observed that my invention provides for an arrangement of multiple bumper rails arranged :to preclude rattling and of relatively light weight and i when struck l'by an obstacle to provide for an increased degree of resiliency and strength against ruptureV and lalso relieving the fixed parts of the car from undue strains. The lprovision o-f the mut-ual resilient relation of lthe bumper rails with one another and combined with the displacement resistingsprings sets upa resistance against displacement of the rails in the event of en countering an obstacle, in a proportion materially more rap-idly than the extent of displacement,r of the struck rail." Such .improved action ensues kby reason of the paths of travel of the bumper rails being disposed at a constantly increasing angle to the path of distension of the displacement resisting springs.

Whereas I have describedmy invention by reference to specific forms vthereofi-t will be yunderstood that many changes and modilications 'may be made without departing from the spiritof the invention.
