Specification of Letters Patent. I
Patented Nov. 1'?, 190s."
Application led September 16,-1907. Serial No. 393,132.
To all 'whom 'it may concern:
Be it known that I, FREDERICK W. K- HAGEN, a citizen of the United States, residing at Marcy, in the county of Lake and State of Minnesota, have invented certain new and useful Improvements in Railroad- Spikes, of which the following is a specification.
This invention relates to spikes, and more vparticularly to railroad spikes, and has for v its object to providea spike of this character with means whereby the spike will be prevented from working loose in the cross tie and loosing its hold on the rail.
Other objects andadvantag will be apparent from the following description and it will be understood that Ychanges inthe specific structure shown and'described maybe made within the scope of the claim without departin Afrom thes irit of the invention.
. the' drawln forming a portion of this specification an Ain which'like numerals vof reference indicate similar parts in the several views, Figure 1 isa front elevation of the spike, Fig. 2 is a'side'elevation, Fig. 3 is a view showing the Vs pike in use, Fig.' 4 ,is a
detail cross section on the Aline 1J-4 of Fig. 2.
' c Referring now more particularly 'to the drawings, there is shown aspike 5, compris-v ing a shank 6 and the head 7. The side walls 48 and 9 -of the shank, are cut into as shown atv-10,`andfbarbs 11 are thus formed which .1 rangement, as shown, but it will be' under-v stood that the barbs may lie with their outer e -in line with the sides 8 and 9 of the shank. The barbs'll are preferably formed in an alternate varbe arranged to produce the best results.
The head 7 of the spike Vvextends transverselyof the frontend rear sides 12 and 1B of the shank, and'a'portion of the shank at l the front and rear sides is broadened as shown-at 14, to strengthen'this end'of the as shown at 19, and this slitted portion of the head 7, as shown.' The lower end ofthe shank 6 is beveled to a chisel edge, as indicated 'at 20, to facilitate driving the spike.V
In use,` .the s ike isdriven into a tie A, as shown in Flg. 3 of the drawings, with the inner ortions of the headl 7 over the flange B o a rail C, and it will be seen that as the lmaterial of the tie enters the space between the'si'des-12 of the shank 6 and the inner edge of the plrong 15, the prong will spread, and after t parent that this prong serves as an eiicient prong extends inwardly of a portion ofthe e spillie--has been driven v entirely into't-he tie .a portion of this prong will li@l parallel with the tie. Itwlll be ap- 65' anchor for the s ike against movement in one direction, an in a direction transversely of the prong, the barbs 11 serve as an additionalanchor. l
What is claimed is:
'As an article of manufacture, a spikeconl- A 4prising a headed shank having a prong ex tending downwardly at -anangle from the head, the head and the shank being kerfed at the juncture of the prong, said prong...
having a fiatv outer face and beveled side faces forming a knife edge adjacent. theV shank.
Intestimony whereof I afx my signature,
in presence of two witnesses.
