-This;invention relates to a bumper construction and more specifically to the end.
' construction of a bumper,
Bumpers as heretofore lrnowncontain re '5 'ognizeddefects and thepractice has been to accept such defects becausebf the lack of remedy therefor; These defects'include' lack of strength and proper yieldability and i'nefiiciency due to accumulation offoreign matterror to corrosion fromthe elements such as {rain or snow,
and corros on.
.. I have discovered, however,that these as,
fects can be obviated and hence one object f my invention is to provide a bumper construction'which is independent of the ele ments and which is closed to foreign parv ticles, thus producing abumper of much greater life and efiiciency. Q v. g 6'7 A further object of my invention is to slmpli fy abumper end construction and at the same time produce an unusually strongand attractive bumper which is economical :to
make and easy to assemble.
2. A further. object is to produce amultiple.
impact .bar bumper. having cylindrical end portions to which a similar endportion of the rear bar is pivotally secured, while at the I same time, allowing for necessary play and I i flexure of the parts. r I
* TAv still further object-is to form the ends oft-he impact bars of a bumper'with corre lated cylindrical terminals, having cutaway portions for guidingand limiting a rearbar .35 whose cylindrical terminal fits partly within the terminals of the impact bars. I I
Y 3 Other and further objects andv advantages I will be understood by those skilled in. this 0 particular field.- V
I have illustrated one embodiment ofmy inventionl' in the accompanying drawings wherein; J I Figure lisaverticalisection through such Fig. Q'is a per'spective view of the end con- "struction ofFigJl-yandl, r 3 s Fig. 3 isia plan view-ofthe'bumper as a whole but omitting the "connections at the or to both such accumulation,
they may be slightly spaced so that they do the rear bar '14,-atthe same time limiting the which is cylindrical also and coiled in the an enlarged head 17 and'a washerfmember 18 100 Similar numerals refer to similar parts throughout the several views.
drical terminal or end portion 11 as clearly 7,
shown in Fig. 2. These cylindrical portions 11 may be t'ormed in any suitable way not forming a part ofthe present invention, but however formed they are provided as shown at the inner central corner with a cutaway no portion12, the form of which is clearly apparent from Fig. 2. v
The impact bars are assembled so that they are vertically superposed and in practice not rub upon one another, although they may, if preferred,'be in substantial contact.
The cylindrical portions 11 are so cutout as at 12 that when theyare' assembled, the cutout portions are adjacent each other, thereby forminga continuous slot, for a purpose which will be hereinafter explained. This slot, as is clear, is bounded top and bottom by the shoulders 13 which act as'limiting abutmentsfor the upper and lower edges of 7 pivotal movement of the rear bar by the ver.' ticalportions-13a of the cutaway portions 12. The rear bar 14 has a coiled terminal 15 ,80 same direction (although not necessarily so) as the portions 11 of bars 10, but the diameter of portion 15 is less than that of portions 11. The dimensions are so adjusted that the'maximum external diameter of portion 15 ofbar 14is not greater than the minimum internal diameter of portions 11 ofbars 10. 'In practice they may be so dimensioned that a'comparatively snug fit is secured which permits relative pivotal movement under impact or stress.
The two bars 10 and bar 14 are assembled as shown in Fig. 2S0 that portion 15 of bar 14 extends part way up into portion 11 of upper bar 10 and part way down into portion 11 of lower bar 10, bar 14 itself being disposed centrally relatively to'bars 10.
. 16. In abumper'joint, two superposed cylinders as the terminiof a pair of parallel im- 7 pactbars,'and a rear bar operatively associated with said impact bars and having a terminal received by said cylinders." 17. In a bumper joint, two superposed cyl- 'inders-as the termini of a pairof parallel im- 7 pact bars, and a rear bar operatively associatedwith said impact bars and having a terminal received by said cylinders, whlch [latter ,are providedv with a, slot, through "which said rear bar extends,
18. Ina bumper joint, two superposed cylinders as the termini of a pair of parallel impact bars, and a rear bar operatively associated with said impact bars and having a terminal received by said cylinders, which latter are provided with a slot, through which said rear bar extends,-said slot lying partly in each cylinder.
. 7 -19. In abumper joint, two superposed cylinders as the termini of a pair of parallel impact bars, and a rear bar operatively assor, ciated with said impact bars and having a V 7 terminal received, by said cylinders, which latter are provided with a slot, through which said rear bar extends, said slot lying partly said rear bar extends, saidfslot lying partly in each cylinder, and being less in extent than the combined "height of the cylinders, and forming a mechanical guide for-said rear bar.
In testimony whereof, I have hereunto subscribed my name this 6th day of November,
1930. I or HARRY R. MGMAHON.
