J. ‘Application May 14, 1935, Serial No. 21,338 6 Claims. (01. 94-15’). This invention relates to composite planks which may have a wide and varied range of usefulness but which are particularly intended and peculiarly adapted for use in construction of 5 heavily travelled decking such for instance as the the longitudinally extending grooves in the tops of the planks are undercut and a series of wood or composite ‘blocks disposed transversely of the grooves for tapered ends to key into the under (a cuts. With this type of ~ construction although boardwalks commonly employed at seashore re- somewhat ‘more expensive originally than ?llers sorts. is even less expensive to maintain because a single ' V These walks are usually elevated so that high tides may flow under them and while the use 10 of an all concrete walk is satisfactory from a worn block may be removed and replaced with out disturbing its fellows. However it is within the scope of the invention to use elongated standpoint of structural strength and durability, wooden or rubber or composition ?llers preformed such walks are > extremely. hot and uncomfort- to be slid endwise into the grooves or to use as able, lack resiliency, are tiring to walk upon and bestos or similar material which may be pre consequently ‘discourage promenading and are 15 resultantly detrimental to the business of merchants and amusement concessions on the walk. A wooden walk is quite comfortable to walk upon. It is not nearly as hot as concrete but it formed, molded or pressed. Into» the grooves. The invention may be more fully understood 15 from the following description in connection with the accompanying drawing wherein:-— Fig. 1 is plan view, partly broken away and in does present a ?re hazard and it is very expen20 Sive to keep in "repair. Furthermore, in many localities such for instance as Atlantic City, these boardwalks must be built to sustain very heavy loads such for instance as the travel of heavy section illustrating one form of my invention, Fig. 2 is an enlarged view in transverse section 20 on the line 2--2 of Fig. l, Fig_ 3 is a, view similar to Fig, 1 illustrating a modi?cation, and 25 in mind the walks1 are built of extremely heavy, on the line 4-4‘ of Fig.3; ' ?re engines Over-them in emergencies- With this Fig. 4 is an enlarged transverse sectional view 25 expensive Wooden Planking which must be re“ placed as Soon 315 ' the Surface‘ thereof becomes sphmiered or‘ spht or “(011m down’ 01' otherfmse While as vabove suggested the grooves in the upper surface of the concrete bases of the planks may receive any suitable type of removable re dgtenora'tes to .a’ condition where pedestrians silient tread member such as elongated wood or 30 mlght trip or imure themselvfas on tfhe walk- rubber members or may be filled ‘with any suit- ~ 9 .An object of. the present Invention 15 to pro‘ able resilient wear resisting material which will Vlde 9‘ cqmpoglte plank for use at such board‘ afford the desired attraction, I have for illuse walks whmh W111 he even strffger .than .the heavy trative purposes shown only the construction in Wood?“ planks now ‘511111129376 ?rms? gnu be sub: which a multiplicity of transversely disposed, 35 sfanmny?re'pmf’ W 10h no .ecome un- uly hot in the sun and yet which will very ma- laterally abutting wooden blocks are employed to afford the desired tread surface terially reduce the cost of maintenance of the Referring more particularly to F'?gs 1 and 2 Waikr'eauue of‘ the invention is the use of a plank of the drawing" 7»!

This mastic may likewise be employed between the ?ller blocks if desired. To anchor the planks I preferably employ nails 5 driven into joists or other supports 6 and hav ing heads ‘I thereon which are forced into longi~ tudinally extending grooves 8 in the sides of the plank. In driving the nails they are positioned close to the planks and when driven in‘ su?i ciently are bent laterally to project the heads of the nails into the grooves. Adjacent planks are thus necessarily spaced a distance apart at least as great as the diameter of the shanks of the description or shown in the accompanying draw ing shall be interpreted as illustrative and not in a limiting sense. Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:— 1. A composite plank, including a preformed base having a recess in its upper face extending throughout its length and transversely posi tioned preformed ?ller pieces keyed in the recess, 10 said base having longitudinally extending grooves in its side edges adapted to receive the spikes or nails. heads of securing devices driven into a support In the modi?cation illustrated in Figs. 3 and ' on which the plank is located. 15 4 of the drawing the plank increased width pro 2. A composite plank including a base having vides room for three parallel grooves l4 corre— a series of parallel recesses in its upper face, sponding to the groove 3. Grooves 9 are formed in the upper face of the base to give to the plank . ?ller pieces keyed in the recesses, said base hav 20 the appearance of a series of single planks, these grooves being of a width corresponding to the spacing of the single planks shown in Fig. 1. While three longitudinal tread receiving re cesses M are shown, the plank'may have two, 25 four or more if desired. In the bottom of the grooves 9 drain openings ID are provided and these drain openings are preferably given the downwardly ?ared or coni cal shape shown to prevent them from clogging. The ?ller pieces 2 when of wood are preferably 30 formed with the grain running vertically and. may be treated in any desired manner to length en their wearing qualities. 35 When a ?ller piece is worn or rotted, it can be dug out of the recess and a three part ?ller piece inserted. This is illustrated in Fig. 1 of the drawing and the parts of the ?ller piece are given the reference characters H, l2 and I 3. The end sections II and I2 have tapered ends to key in: the recess 3 and the center section l3 40 when forced or wedged into position between them insures their interlocking engagement with the base. '. ' It will thus be seen that my improved plank can be easily and cheaply kept in repair reduc 45 ing the cost of maintenance to a minimum. These planks may be conveniently used for the replacement of one of the wooden planks now employed. - It will thus be seen that there is herein de 50 scribed an article in whichthe several features of this invention are embodied, and which article in its action attains the various objects of the invention and is well suited to meet the require ments of practical use. 55 - . l . As many changes could be made in the above construction, and many apparently widely differ-v ent embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above ing longitudinal grooves in its upper face be tween the recesses to simulate separate planks and drain openings in the bottoms of the grooves. 20 .3. A composite plank comprising a base hav ing a dove-tailed recess in its-upper face extend ing throughout its length and removable ?ller pieces in the recess at least one of said ?ller pieces consisting of end sections shaped to ?tthe side walls of the recess and a center section between the end sections holding them in locked engagee ment with the base. 4. A multiple composite plank including a wide ?at preformed base having a plurality of longi tudinally extending recesses in its upper face, tread members removably secured in said re cesses, the spaces between said tread members being relatively narrow and said base having grooves in the spaces between the tread members whereby to simulate separated composite planks. 5. A multiple composite plank including a wide ?at preformed base having a plurality of longitudinally extending recesses in its upper face, tread members removably secured in said recesses, the spaces between said tread members being relatively narrow and said base having grooves in the spaces between the ‘tread mem bers. whereby to simulate separated composite planks, said last mentioned grooves having drain 45 holes therein. ' 6. A multiple composite plank including a wide ?at preformed base having a plurality of longi tudinally extending recesses in its upper face, tread members removably secured in said re 50 cesses, the spaces between said tread members being relatively narrow and said base having grooves in the spaces between the’ tread mem bers whereby to simulate separated composite planks, the edges of said base having recesses therein adapted to receive the heads of securing devices for retaining the composite plank in posi tion.
