Patented Mar. 21, 1933 HANS P. NELsoN,or1 GRAN'rwooD, NEW JERSEY PONY :POLO MALLET A Application inea August 22, 1931. serial No. 555,813. y

`The subject-matter of the present invention relatesl generally to mallets and the improvements are directed toa novel form of head-structure, embodying a protected `and 35 moisture-proof core.

Primarily, the objectof the invention resides in the production of an article ofthe above-mentioned character comprisinga specially treated core, formed from wood, or the like, said core being encased by material -impervious to moisture, thereby lpreventing splitting or checking of said core.

Another object is to provide novel plug means adapted to be treated and secured to the ends of an encased core whereby the admission or penetration of moisture to said core will be positively precluded.

Still another object of the invention is to provide means for checking the entrance of moisture at the junction ofthe head portion and the usual handle, said meansbeing somewhat elastic and adapted to embrace a portion of said handle and to overlie the projected portion of the socketed section of said handle in the head and the adj acentV portion of said head, thus serving to shed the Water or moisture from this connective pointand to prevent seepage to the socketed portion.

VThe invention is further featured Aby. its simplicity in construction of the article and the production of a mallet that will give long and satisfactory service.

With these objects in view, together with others which will appear as the description proceeds, the invention resides in the novel formation, combination, and arrangement of parts, all as will be described more fully hereinafter, illustrated in the drawing, and par ticularly pointed out inthe claims.

In said drawing:

Figure l is an elevation of a polo malletV constructed in accordance with my invention. Fig. 2 is an elevation of one of the. ends of the mallet. Fig. 3 is a central longitudinal sectional view of the mallet with a portion of the handle lshown in elevation. j

Fig. Liis a central longitudinal sectionalV view of the core.

Fig. 5 is an elevation, partly in section,

of` one end portion of afcore vshowinga formed recess to receive a'special plugi Fig. 6 is an elevation of a plug adapted to be assembledA with theportionof the'core shown in Fig. 5; y 55 Referring now more in .detail tothe accompanying drawing, wherein like characters of reference denotefysimilar parts throughout the several views, let'A .denotef generally the vhead portion of [my improved mallet and B the handle adapted to be` asso-fl ciated therewith. In'the drawing only a porl tion of saidhandle B isshown, but it will be understood that saidv handle will bacon-- structedof suitablerrmaterial, of requisite length and provided with the usual attachments as is-we'll-known in the art. v

Upon inspection of Fig. 3 itwillbe seen thatsaid head :A comprises essentially a corel 10, preferably formedfrom selected and well and fine grained hardwoods, said core ,being encased by an impervious casing 11, preferably made of Celluloid, and adapted to` 'cover-` the fulllongitudinal dimensionof said core, thus serving to prevent the splitting of the same longitudinally, which frequent-ly oc-' curs when moisture is present in said core. As shownin Fig. 4, said core Vl() is provided with recesses l2, for the reception of plugs 13, (seeFig. 3)., saidplu', g's,serving'tov seal` the ends of the head :portion or core to pref' vent-'the seepage ,or entrance of moisture to said core, asv will presently appear.V .Said

headrA is associated with a handle B, as mentioned hereinbefore and in this connection it will be noted that said core is provided with an angularly disposed opening 14 and that said casing l1 is provided with alined openings-l5 and 16 for the receptionrof-one f end of the handle. Again referring to F ig; 9o 3 it will be further observed 'that one eXtremity of said handle B is split at 17` forthe reception of awedge 18, thelatter serving to slightly spread 'the end of th'erhandle to assure a snug and vtight fit at this pointof connection. It will be noted `that I have also provided means to lprotect the jointadj accnt the opening 16 and fthecontignous portion of the handle, saidmeans ybeingin. the form of an elastic sleeve 1,9, which embraces .thatporf Y tion of the handle above said opening 16 and which spreads circumferentially about said opening and substantially concentric therewith to positively seal the opening and to prevent the admission of moisture to that portion of the handle embedded in the casing and core.-

' From the foregoing it will be seen that I have provided a mallet embodying a core` suitably sealed and protected from the deleterious effect of moisture and the like. Further, the mallet is of suitable weight and adapted to give long service.

As mentioned hereinbefore, said Core 10-is made from suitable fine-grained hardwood, which is first turned to the shape indicated in the drawing and provided with opening v14 n and the recesses 12. In this condition the tube having been Cut approximately one-half an inch longer than the'core so that ends i" thereof will extend beyond the ends of said Core a suitable distance. The vCore and the tube of Celluloid are now placed in Cold water whereupon the contraction of said Celaluloid Causes the tube to clinch and bind around said core tol form the Casing 11, thus sealing the encased portion of said Core. The plugs 13 are next affixed within the recesses 12, said plugs having been previously treated exteriorly with a Celluloid tenacious and liqi uid substance, and forced into said recesses 12 to assure a moisture proof connection at all points.- As shown in Fig. 3 said plugs 13 are screw-threaded and'provided with square sockets 13al into which a suitable tool may be inserted to Cause the plugs to Cut their own threads into the recesses 12. It is obvious Jthat the substance appliedto said 'plugs' will fill and close all openings between the core and plugs and provide an air andmoisture proof- Connection at either end of the mallet. It will be appreciated that the plugs may be deprived oftheir threads and a special plug 20, (see Fig. 6) vused instead. In this'instance the plug or plugs are treated as before and forced into the recess 21 formed in the end ofthe mallet 22 shown in Fig. 5. In all other respects the operations are the same.

" 'After the plugs have been suitably affixed,

said Celluloid Casing l1 is trimmed atkthe ends, finished and rounded over to present its extremities flush with the end faces of said plugs 13- or 20, as shown in Fig. 3. The han- Y es dle- B is next inserted in the openings 14, 15 and 16, as described hereinbefore, and the wedge 18V applied to firmly bind the same Lacasse creates a partial vacuum at that point so that no air or moisture can find its way into any' opening or joint.

While the present isa disclosure of the preferred embodiment of the invention, it is tovbe understood that the invention is` not limited thereto, as'various changes in theVY ininordetails of Construction, proportion and arrangement of parts may be resorted to without departing from the spirit ofthe invention as defined in the appended claims.

I claim: l

L rilhe herein described process of making a mallet vwhich Consists in treating a wooden core in vheated oil to render the same impervious to moisture, afixing and shaping a prepared Cylinder of Celluloid'V about said. core and finally afxing moisture-proof plugs to the ends of said Core to seal the connection between said core, said cylinder of Celluloid and said plugs. Y p

' 2. rihe herein described process of making a mallet which consists in treating a wooden core to'render the same impervious to 'mois-V ture, afxing a. prepared cylinder of Celluloid about'said Core and finally afxing vmoisture-proof plugs to theends of saidY Coreto seal the connection between said Core, said Cylinder of Celluloid and said plugs.

3. A polo mallet Comprising a woodenr Core having its extremitiesA recessed, a Celluloid Casingfembracing .said core and having itsv ends overhanging-the recessed extremities of said Core, and plug means fitted into the recesses of said Core and iillingthe spaces beneaththe overhanging ends of said Casing to seal the ends of the mallet, f

4.-. A polo mallet comprising a core having an angularly disposed opening, a casing eni-v Y bracing said core and having openings alined with the opening in said Core, means for seal# ing the exposed ends of said core, an handle insertible in the openings in said Core and Casing, and an elastic sleeve embracing that portion of the handle above one of the openings in said casing, and contacting with said casing about said opening to 'seal'the same and to prevent the admission of moisture; to that portion of the handle embedded in the casing and core. Y

In testimony whereof l affix my signature.
