TURPENTINE-CUP.

To all whom t mag/concern:

' Be it known that I, JOHN MILLENnEn BYRD, a citizen of the United States, resid-` ing at Hazlehurst, inthe county of Jeff Davisand State of Georgia, have invented. certain new and useful Improvements in Turpentine-Cups; and I do declare the following to be a full, clear, and exactdescription lof the invention, such as will enable others skilled in the art to vwhich it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in sap receiving receptacles, such, for instance, as are commonly employed to receive crude turpentine as it runs from the tree. These receptacles, as is well known, comprise an apron which is secured to the tree and a cup or box into which the flowing sap is deiiected by the apron. Various forms of cups have been'designed but in every instance, their practical value has been materially reduced or rendered negligible by some peculiar or distinctive feature of construction.

A receptacle according to the present invention, embodies as heretofore the apron and the cup but theseparts are of such construction and association that the various objectionable features which are v inherent in the prior constructions are'avoided and the resultant structure is one which is essentially practical and inexpensive and which has a greatly superior degree of utility.

The novel features of construction and association which characterize the present improvement will be pointed out succinctly in the detailed description which follows.`

The invention is illustrated in the accompanying drawings wherein;

Figure l is a view showing the improved receptacle applied to a tree; Fig. 2 is an enlarged perspectivev View of the receptacle; Fig. 3 is a developed plan view of the blank from which the receptacle is formed; Fig. 4c is a vertical section taken through the transverse center of the cupor box.

Similar characters of reference designate corresponding parts throughout the several views. Y

The improved receptacle is constructed of sheet metal'and its parts are preferably ntegral.

Specification of Letters Patent. Patented Dec, 15, 1914, Application lediJuly 15, 1910. Serial No. 572,198.v

The apron isy designated generally by the numeral l and the cup or box is designated generally Aby the numeral 2. Said cup or box comprises the. front and back walls 3vr and 4, and a connecting web 5 which forms both the bottom andr end walls. The walls 3. and Zlare perfectly fiat and are disposed in parallel relation so that the distance between them is the same at all points. These walls aremoreover of approximate though not quite true semi-disk shape, their upper edges being straight and their under edges curved. The web 5 joins the curved under edges of the walls 8 and el and hasthe same This contour is such that the central portion of said web as 5a which forms the bottom of the cup, is of concave outline, while the end portions of said web as 5b, which form the end walls of the cup are straight, so that the cupy in longitudinal vergent tangent lines, the arc portion formin@ the bottom of the cup and the diverging tangent portion forming the end walls of the cup. These straight end portions 5b merge gradually with the central portion 5a and extend upwardly from the latter in divergent relation, their upper edges ybeing flush with the upper edges of the walls 3 and 4- and together with the latter defining the open rectangular mouth ofthe cup.

The apron l is of substantially rectangular outline and it extends upwardly and rearwardlyfrom the wall 4 at an angle of about 350. Said apron is permanently joined to the upper edge of the wall 4, the meeting lower edge of the apron and upper edge of said wall defining a straight line. The apron is moreover co-extensive in length at all points with the upper edge of the wall 4. Hence the end edges of the apron are parallel. T hese parallel end edges are provided with upwardly` directed parallel flanges 6 which are curved in cross section and `which extend to the aforesaid rectangular mouth of the cup. These flanges, however, terminate short of the rear edge portion of the apron so that corner shoulders, as 7 are formed.` The projecting rear edge portion affords a. projecting lip, as 8, which efficiently engages in the kerf made inthe tree.

The manner in which the cup is fitted to the tree is shown in Fig. 1. The lip 8 is engaged in the kerf and a nail or other fastening device is drivenv through the apron ,section defines an arc of a circle having diat a central point inorder that the attachment of the receptacle may be of positive nature. The sap which runs from the tree is deflected by the apron into the cup in the well known manner. The practical etliciency of the device accrues from the com bined relation of the following advantages.

@wing to the permanent association of the apron and the cup the latter can never bedisplaced from they former and the removal of the receptacle for dippingv is unnecessary. By reason of the permanent association of the parts referred to coupled with the corner .shoulders 7 which engage against the tree at both ends of the cup, the

klatter remains in its proper position, under all conditions and cannot, by accident or by the rubbing of animals be moved in any direction. Owing to the fact that the apron is co-eXtensive in length atall points with the length of the mouth of the cup coupled 'with the provision of the flanges 6 all of thev sap which flows upon the upper portion of the apron is deflected by the latter; there is'no waste and the sap iows in a straight uninterrupted path.` rlhe flat form of the rear wall 4 adapts the device to trees of dif- 'ferent diameter and degrees of curvature and the relation of the apron to this rear wall is such that the cup is caused to hug the tree. This fact coupled with the fact that the flanges 6 extend continuously between the tree and the cup, renders it impossible for any sap to escapey around or under the flanges ofthe cup or to enter between the latter and the tree. Owing to the fact that the walls 3 and 4 are fiat and parallel either a right or left hand dipper may be used. Moreover the form of these walls coupled with the form and relation of the web 5 assures that all of the turpentine may be removed and that movement of the clipper is effected with as little friction as possible. The curved cross sectional'form of the flanges 6 provides for a ready cleaning of the gutters afforded by said flanges.

' The relation and form of the parts are of suchnature that they may be made integral and that the device may bestamped from sheet metal.v The blank from which the device is `stamped is shown in Fig. 3 wherein the lines l0 define the adjoining edges of i the web 5 and the walls 3 and 4; the line 11,

defines the adjoining edges of the walll 4 and the apron l and the lines l2 and 13, together with the parts of the lines l0 which n adjoin the lines l2, define portions as 14 which'are folded in overlapping relation against the outer faces of the portions 5b of the web 5 and which materially strengthen the cup as well as its connection with the walls 3 and 4.

The receptacle, being made of sheet metal, and embodying no separable or extraneous parts f is `not affectedvby Weather conditions,

avoid the formation of an acute angle be`- tween the iianges and shelf ofthe apron for thelodgment and caking of the turpentine when stil and thick in the early spring and late fall of the year. By forming' the body of the box or cup as described so as tol vdefinev in longitudinal section an arc of a circle having divergent tangent lines, the end walls are straight divergentwalls vmerging at the lower endsjinto a concave bottom so that there is formed for thel turpentine a receptacle in which the sweep of the turpentine dipper at the bottom of thereceptacle is short and in the arc of a circle while the sweep at both ends is straight and at a relatively sharp angle and this gives the advantage of less friction between the dipper and walls of the receptacle and the removal of the turpentine with .greater ease and more effectively because the space at the bottom for the turpentine to settle or fall .back is reduced to the minimum. Y

Having fully described my invention'and set forth its merits, what I claim is: v l. A'receptacle of the'type set forth com prising a cup which embodies flat parallel n front and` rear walls having curved' under edges and a connectingiweb joined'to said edges, conforming to the curvature thereof, and forming the bottom and endwalls of the cup, and an apron which projects rearwardly and upwardly from the upperedge of the rear wall7 the apron being of rectangular form and being at all points co-eXtensive in length vwith the length of the mouth of the cup defined by the upper edges of said front and rear walls and said web, vthe apron being furthermore permanently joined to the rear wall and having at its ends parallel upturned flanges which extend continuously from the said mouth to the tree edges, conforming tothe curvature thereof and forming the bottom and end walls of the cup, the web'having a central concave portion and straightA end portions. which merge` with the` central portion and which project upwardly therefrom'in divergent relation,- and anapron which projects rearwardly and upwardly from the upper edge of the rear Wall, forming a cup which defines in longitudinal section an are of a circle having diverging tangent lines, the apron being of rectangular `form and being at all points co-eXtensive in length with the length of the mouth of the cup defined by the upper edges of said front and rear Walls and said Web, the apron being furthermore permanently joined to the rear Wall and having at its ends parallel upturned fianges which extend continuously from the said mouth to the tree upon which the receptacle is secured.

3. A receptacle of the type setv forth cornprising a cup which embodies flat parallel y front and rear Walls having curved under edges and a connecting Web joined to said edges, conforming to the curvature thereof, and forming the bottom and end Walls of the cup, and an apron which projects rear- Wardly and upwardly from the upper edge of the rear Wall, the apron being of rectangular form and being at all points (3o-extensive in length with the length of the mouth of the cup defined by the upper edges of said front and rear Walls and said web, the apron being furthermore permanently joined to the rear Wall and having at its ends parallel upturned flanges Which extend continuously from the said mouth to the tree upon Which the receptacle is secured, the flanges terminating short of the rear edge of the apron whereby corner shoulders Which abut 'against the tree and a projecting portion which is formed as a lip to engage in a kerf in the tree, are provided, the ends of the `projecting lip being in alinement With the base line of said anges, substantially as described. j
