This invention relates to certain improvements Y in archery bows and sights therefor, and the nature and objects of the invention will be readily recognized and understood by those skilled in the art to which the invention pertains, in the. light of the following explanation and detailed description of the accompanying drawings illustrating what I now consider to be the preferred embodiments or mechanical expressions of my invention lo from among various other forms, designs, ar-

rangements, constructions and combinations of which the invention is capable withinthe broad spirit and scope thereof.

Archery bows generally are of a length of the l5 order of approximately six .(6) feet, at least, so

that they are rather unwieldy and cumbersome for transportation and/or storage. Various designs and constructions o f such bows have been suggested to 4enable their being disassembled or knocked-down into sections for carriage or stor age purposes, but generally such suggested designs involve complex constructions with increased number of parts and elements making up a bow, so that not only is the cost of the bow increased but the eiiiciency and accuracy may be decreased. y It is a general object of my present invention to provide a design and construction of archery bow which may be readily disassembled or knocked down for carriage or storage purposes, but which is `of extremely simple construction to embody merely a handle and upper and lower limbs detachably received by the bow handle without the use of any fastening means, such as screws, clamps or the like, and with' the bow limbs main- 30 tained in assembled relation with the bow handle merely by the bow string in operative position placing the limbs under tension, and the limbs releasable for disassembly and removal from the handle by detaching the bow string from opera- 'tive engagement with one of the'bow limbs.

A feature and characteristic of the invention in carrying out the foregoing general object resides p in the design of the bow handle to provide opposite end bow limb receiving sockets and in the construction of the inner ends of the bow limbs to fit into the handle sockets in such a manner` that, as the bow string is drawn back by the archer to release an arrow, the ends of the limbs are tightened in the handle sockets.

Another object .of my invention is to provide an improved design of sight for an archery bow, which is readily adjustable universally, that is, vertically and laterally, as required to meet lthe needs of a particular archer and the requirements of the particular conditions under which a bow is being used.

A further object of the invention is to provide an efiicient design of mounting for the sight on a bow of the foregoing type, by which the sight is 5 adapted to be maintained in operative position on the bow by securing the sight mounting in the upper end socket of the bow handle between the handle land thel end of the upper limb of the bow received in such socket, the sight being detach- 10 able and removable when the bow is disassembled.

Another main object of my invention is to provide a design, construction and arrangement of knock-down or sectional bow of the above referred to character, which is extremely simple 15 mechanically and structurally and embodies a minimum ofv parts and elements capable of ready manufacture at relatively low cost, yet which provides an efficient and accurate bow in use; and further which enables the bow limbs being con- 20 structed of such wood materials as have been established as preferred and most eicient for archery bow purposes. I

With the foregoing general objects in view, as well as certain others which will be evident from 25 the following description, myinvention consists in certain novel features in design and in combination and construction of parts and elements, al1 as willbe more fully an'd particularly referred to and specified hereinafter. 30

Referring to the accompanying drawings, in which similar reference characters refer to corresponding parts throughout the several figures thereof:

Fig. 1 is a view in side elevation of an archery 35 bow and sight embodying the invention, in 'assembled and operative position.

Fig. 2 is an enlarged perspective view of the bow handle and inner ends of the upper and lower' bow limbs together with the bow sight, o y

when separated and disassembled but in their relative positions for assembly.

Fig. 3 is an enlarged view in side elevation of. the bow handle with the upper and lower limbs of the bow in assembled position in the handle 45 sockets and the sight in mounted position, the inner end portions only of the bow limbs being shown. l

Fig. 4 is a view in rear elevation of the assembled bow handle, limbs and sight of Fig. 3.

Fig. 5` is a view in vertical longitudinal section through the bow handleof Figs. 3 and 4, the ends ofthe bow'limbs and the bow sight mounted in the handle being shown in side elevation.

Fig. 6 is a horizontal, transverse section u Fig, 3, and showing the sight mounting plate in assembled position in the handle socket.

Fig. 7 is a view in rear elevation of the inner end of the lower limb of the bow showing the wedge block or member thereon for cooperation with the bow handle socket.

One possible embodiment of an archery bow incorporating the several features of the invention is illustrated by way of an example in the accompanying drawings, and essentially includes', referring particularly to Fig. 1, the bow handle I0, upper limb 20, lower limb 3l, and the bow string 4u. In accordance with theinvention,.the upper and lower limbs 2l and 30 are removably maintained in the opposite ends, respectively, of the bow handle I by the bow string dll connected .to and between'the bow limbs in operative position drawing or bending the limbs rearwardly to initially place the limbs under tension for use of the bow. Due to the design and construction of the bow handle and the inner ends of the bow limbs, the latter are held and maintainedin their operative, assembled position by the bow string in its above referred to operative position as shown in Fig. 1, and are released for removal by unstringing the bow, all without the use of any fastening'or other means for securing o'r clamping the bow limbs into the bow handle.

In the present instance, I have selected a design and constructionfor the bow handle IB, by which the handle is formed of atubular metal element, such as a casting orthe like of a lightweight metal as aluminum, or one of the metal alloys as duralumin, although my invention is not limited to any particular material for the bow handle forming element. This handle forming element is slightly bent or curved rearwardly from its central portion toward its opposite ends, that is, is of slight arcuate form, and preferably is provided with the end beads or rounded guard shoulders Ita extended at least around the side and rear of each end of the handle member.

Along one side of the handle element. in this instance, the left side, a longitudinally extended raised portion Ib is provided intermediate the opposite end beads Ida, to form a surface against which an arrow to be cast by the bow is held and across which the arrow slides in drawing the bow and releasing the arrow. It desired, such an arrow engaged surface IIIb may be provided on the right side of handle ID, or such surfaces may be of the outer surface oi the raised, arrow engaging portion Illb ofthe handle forming element.

The bore or `passage II (see Fig. through the tubular handle forming element. may be. as in the 'example hereof, of. generally rectangular cross section, that is non-circular but having roimded or curved corner portions. This bore II -from its intermediate or central portion within the elementincreases in width or cross sectional areaoutwardly to the opposite ends of the handle to forni the'upper end and lower Tend bow limb receiving sockets I2 and I4, respectively.

The upper end socket I! of handle Il has its rear wall I 2a curved or inclined upwardly` and arcanos rearwardly from its inner end (see Fig. 5) and is transversely curved so as to be substantially concave in section, as will be clear from Fig: 6. The

' forward wall I2b of this upper socket is substantially straight and presents a hat surface with a vertical groove'or slot I2c formed extending longitudinally thereof, which slot opens' through the Y upper edge wall of the handle forming element and also has in the example hereof, its opposite side edges undercutas shown by Fig. 6.

The lower end socket I4 of the bow handle has the rear wall Ila thereof curved or inclined outwardly and rearwardly (see Fig. 5) and is trans- .versely curved so that such wall is substantially concave in cross sectin, in a manner similar to uppersocket rear wall 'I2a as shown by Fig. 6. The forward wall Ilb of this lower bow limb socket is substantially straight and presents an approximately flat surface, as will be clearA by reference to Fig. l in connection' with the showing in Fig. 6 of the similar forward wall VI'ib of the upper socket I2 of the bow handle I0.

The upper and lower bow handle sockets I2 and I4 are designed to removably .receive and hold the inner ends of the upper and lower bow limbs 20 and 3i! with lsuch elements of the bow in assembled position as shown by Figs.- 1, 3, 4 and 5 of the accompanying drawings. Due `to the design and construction of the bow Yhandle sockets and the arrangement of the invention for releasably holding the bow limbs therein;l solely by forces exerted thereon by the bow string 4l in .strung position, the bow limbs can be practically manufactured from any of the woods efciently suitable for archery bow use, such for example, as hickory, ash, lemon, yew and hedgewood.

The upper and lower bowlimbs 20 and 30 are substantially identical in design and construction, each being formed of a length of a suitable wood which is tapered or decreased in cross sectional area outwardly and is preformed or .shaped to curve outwardly and rearwardly from the inner end portion of the limb, as willbe clear by reference to Fig. l of the drawings in particular. Each bow limb in the example hereof is formed with the substantially flat forward side or surface I, and terminates at its inner end in the root or handle socket iltting portion'2. Such root or socket fitting end portion 2 of a bow limb is formed by reducing the width of the bow limb to provide the shoulders 2a at opposite side edges of the limb and then tapering such root or socket portion outwardly to the end therelof. Each tapered inner or root end 2 of a bow limb isshaped to fit into a socket I2 or Il of the bow handle III, and is provided with the forward sidesubstantially straight fiat wall 2b (see Figs. 2 and 5) adapted to fit against the forward fiat wall I2b or Mb of a handle socket I2 or I4,"with the bow limb in mounted position in such handle socket.

Following a ,further feature of the invention, each bow limb 2l and 30 is provided with means l .for cooperating with the rear wall of the handie socket I2 or Il in which mounted, to cause a -wedging and tightening' of the bow limbs in their respective handle sockets as the bow string 4I 4is drawn back for casting or propelling an arrow.

- Such a means in the present example, takes the form of a wedge block 2 secured in fixed position on the rear side of each bow limb root 2 adjacent. the shoulders 2a of the limb. Eachwedge block 3 decreases in thickness from its o terl end inwardly along the limb root by sloping or inclining its outer side inwardly toward l Vis adapted to be mounted on the mounting in the limb root. These wedge blocks are preferably formed of a hard wood, such, for example, as ebony wood, and are secured to the limb rootsA 2 in any suitable manner, as, for example, by means of a suitable fastening element, such as a nail screw or the like 3a. (see Fig. 5), with or without the use of glue or cement between the limb root and wedge block, as may be found expedient.

The archery bow of the invention is assembled for use, referring now to Figs. 1 and 5 in particular, by freely inserting the root ends 2 of the upper and lower limbs 2U and 30 in the handle sockets I2 and I4, respectively, of the handle ID, with the flat front walls 2b of the limb roots engaged against the flat forward walls I2b and I4b, respectively, of the handle sockets. In such inserted assembled position, the wedge blocks 3 of the upper and lower limb roots 2 fit within the sockets in engagement with the outer vend portions of the rearwardly and outwardly curved rear walls |2a and I4a, respectively, of the said handle sockets, as clearly shown by Figs. 3 and 5 of the drawings'. The bow stringl40 is then connected into operative position between the outer ends of the assembled upper and lower bow limbs 20 and 30 to initially bend or draw the limbs rearwardly into initially sprung position, in the usual manner of Stringing an archery bow familiar in this art. l

Thus, under the action of the bow string 40 when so connected between the bow limbs 20 and 30, the inner, root ends 2 of the limbs are'firmly forced and held in the handle sockets l2 and I4 in assembled position to complete the bow ready for use, as shown by Fig. 1. As a result of the design and relative arrangement of the wedge blocks 3 and their position in the handle sockets, each time the bow string 40 is drawn rearwardly 4into arrow casting or projecting position, these hard wood blocks function as wedges acting against the curved rear socket walls I2a and I4a, to further tighten and force the limb roots 2 into` the sockets and tightly and rigidly hold the limbs in fixed position during the drawing of and arrow casting by the bow. Hence, such tight mounting and substantially rigid mounting of the bow limbs 20 and 30 in the bow handle I0 is accomplished solely by the forces acting on the limbs when the bow is strung for use, and entirely without the employment of any separate or additional securing or clamping means.

When it is desired to disassemble the bow for transportation or storage, it is merely necessary to unstring the bow by detaching the bow string 40 from one of the bow limbs, which instantly releases the tension on the limbs that holds them in their assembled position in the handle sockets, so that the bow limbs 20 and 30 can then be removed from the sockets I2 and I4 to separate them from the handle I0.` Assuming a bow of substantially a six (6) foot length, the disassembled or knocked-down bow can then be transported or stored to occupy a space of a length of not over approximately a length of thr'ee (3) feet.

The invention also includes a bow sight S and its mounting as a feature thereof, in combination and cooperation` with the knockdown or sectional bow of my invention as hereinbefore described. The sight S consists of tube or sighting member 50 of any suitable material, such, for example, as aluminum or other light-weight metal or alloy.

This tube-has the restricted sight opening form- V ing forward end 59a and the rear enlarged bore eye opening providing end 50h. The sighting tube generally horizontally disposed position but adjustable so as to have its bore lined between an ,eye of the archer and the target.

A mounting for the sighting tube 50 providing for elevational and lateral or horizontal adjustment is provided, and in accordance with my invention such mounting is designed for cooperative combination with the upper bow limb 20 and the upper socket' I2 of the bow handle I0. Such a mounting mayf as in the example hereof, embody a mounting base plate 5| of'`y general wedge formation having a laterally extended arm 52 at its upper end which arm terminates in a vertically disposed column or standard 53. A bracket 54 is slidably mounted on column 53 fo-r Vertical adjustment as well as horizontal or rotary adjustment thereon. A set screw 54a is provided for securing bracket 54 in its adjusted positions on column 53. The sighting tube 50 is formed with a depending arm 55 intermediate the length of the tube, which is rotatably mounted on the outer end of bracket 54 for vertical rocking or elevational adjustment thereon. A clamping screw 56 is provided for securing the arm 55 and its tube 50 in adjusted position.

The sight S and its mounting are secured in position on `the bow when the latter is assembled by inserting the base plate 5I downwardly in the undercut slot l2c formed in the forward wall I2b of the upper limb slot I2 of the bow handle. The vertical column of the sight mounting is then disposed on the left side of theA bow with the sighting tube 50 in generally horizontally disposed position spaced from the left side of the upper bow limb 2D. This arrangement and location is preferred for an archer who holds the bow in his left hand by handle I0 and draws the bow with his right hand, but if desired the sight can be arranged for mounting to locate tube 50 at the right side of the bow to accommodate an archer holding the bow with his right hand and drawing the bow with his left hand.

In either mounting arrangement the mounting platel in socket slot I2C is located so as not to interfere with the insertion or removal of the upper how limb 20 in socket I2, and the root end 2 of limb 2D when inserted and secured in the socket may bear against and wedge the plate 5| in position against displacement so as to maintain the mounting and sight carried thereby in the required operative position on the bow. Upon removal of the upper bow limb 20, thel mounting plate 5I for'sight Sis released and the sight and its mounting may then be removed as aunit.

Due4 to the adjustments provided by the sight mounting; the sighting tube S can be rais-ed or lowered on column 53, can be swung horizontally or laterally about column 53 as an axis, and can be rocked vertically for elevational angular' adjustment about the bracket 54 as an axis. Thus, the sighting tube 5I) can be positioned to meet .the sighting requirements of the archer using the bow, both as to initial position relative to the eye of the archer and as to the sighting requirements under the conditions of use of the bow as to target and windage.

By the design, construction and arrangement of the foregoing described embodiment exemplifying the several features of my invention, I have produced an archery bow of extreme simplicity structurally and a bow capable of ready manufacture at low cost of production, yet which is capable of being knocked-down or disassembled quickly into sections for 4transportation and storage. The bow can be as readily assembled by simply placing the bow limbs in the handle sockets and then stringing the bow, without requiring any other fastening,

` clamping or securingmembers than provided by the bow handle sockets, bow limbs and bow string in their cooperating relation in assembled positions. I have further provided a practical and eiiicient sight for an archery bow together with a.r

mounting for positioning the sight on the bow, and have designed and arranged the sight and its mounting for cooperative assembly with the bow handle and one of the separable bow limbs so that the sight and mounting can be assembled in combination with such elements of the bow but by which the-sight and its mounting can be assembled on or removed from the assembled bow without requiring disassembly or separation of the bow elements.

It is also evident that various changes, modifications, substitutions, additions and eliminations may be resorted to without departing from the broad scope of my invention, and hence I do not desire to limit myself in all respects to the exact and specific disclosures hereof.

Desiring to protect my invention in the broadest manner legally possible, what I claim is:
