3 Claims.

This invention relates to arrow heads.

An object of this invention is to provide an.

arrow head embodying three blades with an lin proved means whereby the. blades are mounted onth shaft.

'Another object of this invention is to provide an arrow head having three blades wherein each blade is formed of two face abutting plates, the plates being arranged in obtusely related pairs connected together by partly circular socket formingjb'ands, and one plate of each pair being secured in face abutting relation to a plate of another pair. The connecting bands between each paiiof plates are so arranged that when the plates are secured together a tapering shaft socket will be formed, and when the shaft is in the socket the shaft will form a lock for the bands and plates.

To the foregoing objects, and others which mayv hereinafter more fully appear, the invention consists of the novel construction, combination and arrangement of parts, as will be more specifically referred to and illustrated in the accompanying drawings, but it is to be understood that changes, variations, and modifications may be resorted to which fall within the scope of the invention as claimed.

Referring to the drawings andj'first toFigures' l to 9 inclusive, the numeralsj26 and Z1 desig nate generally pairs of, bladeforming plates ,oi, tapering or pointed configuration. Theblade'; forming plates 25, 2E and 21 are of like construe; tion as to the major portions thereof andeachi includes a relatively wide plate 28 and; a sub= stantially narrow plat 29. The two plates, 28"? and 29 merge together at their forward ends and; form a point 36. The two plates Hand .29 at" their forward junction point'are adapted to "be? bent onan obtuse angle along ;the line IN. The; plates 28 and 20 are connected together by meansg of a plurality of arcuate and longitudinallyspacedii apart connecting bands 32 which are of a'lengthl greater than a semi-circle and less than a come plete circle so that when the three pairs of plates: are connected together with'the bands'intermeshL- ing a shaft socket of tapering'configuration will? be provided.

As shown in Figure 1, the-blankhas the upper band 32. at the upper extremity thereof whereas-i; in Figure 2, the upper band 32a =is spaced downwardly a'slight distance from the upper-or--rear ends of the plates and in Figure 3, theupper-bande2 32b is spaced forwardly an additional distancefrom the rear ends of the plates. Theofisetting g of the. bands of one pair of plateswith respect to the bands of the other pair of plates-is such' th'at' there willbe at least two bands disposed'inedges abutting :relationas indicated at -33"and.-'-3t in Figure 3. r

In orderto provide forclo'sing. of=the spaces-he tween respective pairs ofbands-of adjacent plaitesr eachbandhas. secured thereto a. relatively smalht plate .35 which :is' of a length 'esubstantia lly: equals;

to oneshalfl the. length a of: the. band with F whichi-r the plate'...35 is connected and-the. heightiotitlien plate 35 is substantially equal to one-half the space between adjacent bands as clearly shown in Figures 1, 2 and 3. When the bands 32, 32a and 3212 are interlaced and disposed in substantially edge abutting relation as shown in Figure 8, the plates 35 are bent upwardly so that a substantially solid socket is formed within which the pointed lower or forward end 36 of the shaft 31 is adapted to be wedged. The plate 28 as shown in Figure 9 is formed with a lengthwise extending offset inner portion 38 within which the narrow plate 29 of an adjacent pair of plates is adapted to engage. The two plates 28 and 29 are secured together by means of tongues 40 which are struck from the plate 28 and are adapted to extend through slots 4| formed in the plate 29. The plate 29 is also formed with a depressed portion 42 extending from the slot 4| so that the tongue 40 will lie flush with the adjacent face of the plate 29. The plate 29 engaging in the depressed portion 38 of plate 28 may also be further secured by soldering, welding or the like as indicated at 5:3.

As shown in Figure '7, the plates 28 and 29 are disposed on an obtuse angle relative to each other with the bands of alength substantially equal to two-thirds of a circle and the three plates forming the three blades are assembled by first bending the plates 35 at substantially right angles to the bands and then intermeshing the bands together with the wide plate 28 disposed in face abutting relation to a narrow plate 29 of an adja- .cent pair of plates. In the initial assembling of :the'pairs of plates they are locked together by ;means of the locking tongues 40 and may then be further secured together by soldering, welding or the like and at the point of each arrow head the :meeting edges of the plates are adapted to be soldered or otherwise secured together so as to form :a solid point structure.

Referring now to Figure 13, there is disclosed :an arrow head similar to the arrow head shown in Figure 8 with the exception that the plates 44 which are similar in every detail to the plates 28 are not formed with the offset portion 38 and the narrow plates 45 are fixed in face abutting relation to the plates 44 by soldering, welding or the like as indicated at 46. In other respects the pairs of plates are similar to the plates shown in Figures 1, 2 and 3, being connected together by the arcuate connecting bands and each band has associated therewith a small plate similar to 35 for closing the spaces between pairs of the bands when they are in intermeshing position.

Referring now to Figures 11, 11a and 12, there is disclosed another form of locking means for locking the plates together. Plate 41 is formed 'with a looped keeper 48 and adjacent plate 49 has :struck therefrom a locking tongue 50 which, as .shown in Figure 12, is adapted to be threaded :through the loop 48.

Referring now to Figures 14 to 17 inclusive,

: there is disclosed another form of arrow head wherein the pairs of plates 51 and 52 are of equal 'width throughout the length thereof and at their outer edges the plates 5| and 52 are tapered or i'beveled as indicated at 53 and the outer portions iofthe plates 5| and 52 are secured to the adjacent plates by welding, soldering or the like as indi-- cated at 54. In the arrow head structure shown in Figures 14 to 17 inclusive a ferrule or metal socket 55 is fixed by fastening means 55 in the socket formed by the'bands 51. The lower tapered end 58 of the shaft 59 is extended into and wedged in the ferrule or socket 55 and may be further secured by fastening means 60. The ferrule or socket 55 is slightly less in length than the length of the socket formed by the bands 51 and at the lower or forward portion of the socket formed by the bands 51, the plates forming the blades are locked together by means of a tapered locking pin 5|. This locking pin 6| forms a means whereby the plates forming the blades may be initially locked together in assembled form prior to the welding or otherwise securing of the plates together.

Referring now to Figure 18, there is disclosed diagrammatically an arrow head wherein the rear portion 62 thereof is of barbless configuration, Whereas in Figure 19 the arrow head 63 is formed at the rear thereof with semi-barb points 64. In Figure 20 the arrow head 54 is formed with full barb members 65 extending rearwardly from the blades.

While in Figure 8 I have shown the adjacent face abutting plates 28 and 29 secured together by means of the tongues 40 seated in depressions 42, it will be understood that these plates may be secured together by means of spot welding, soldering or other suitable fastening means. The locking means for the plates shown in Figures 10, 10a and 10b may be used with any of the forms of invention shown herein, and in like manner the locking means shown in Figures 11, 12 and 11a may be used with any of the forms of invention shown herein.

' I claim:

1. An arrowhead comprising three arrowhead forming elements, each of said elements including a pair of elongated obtusely angled portions joined together along the inner edges thereof, said elements being disposed in confronting relation to each other with each of said angled portions abutting an angled portion of another of said elements to provide a radially extending blade, each of said elements being formed at the inner edges of said portions with a plurality of longitudinally spaced apart offset arcuate bands adapted to extend through th other of said elements and to coact with the arcuate bands on 7 said other elements to provide a shaft receiving socket.

2. An arrowhead comprisin three arrowhead forming elements, each of said elements including a pair of obtusely angled elongated portions and means connecting the inner edges of said angled portions together, said elements being disposed in confronting relation to each other with" each of said angled portions extending radially and abutting an angled portion of another of said elements to provide three radially extending obtusely angled blades, each of said means including a plurality of longitudinally spaced apart oifset transverse arcuate bands adapted to engage between the means on the other of said elements and to extend therethrough to provide' a shaft receiving socket.

3. An arrowhead as set forth in claim 2, in which means are provided for securing said abutting angled portions to each other.
