Specification of Letters Patent.

Patented Feb. 210, 1914i.

Application filed February 3, 1911. Serial No. $06,349.

To all whom it may concern Be it known that 1, LA Vanna WVJNOYES, a citizen of the United States, residing at Chicago, in the countyof Cook andState of Illinois, have invented a certain new and useful Improvement in Engines, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to engines that include fly wheels in their formation and has for its object the provision of an improved engine base for supporting the fly wheel or fly wheels of ancengine clear of the level upon which the engine stands.

The preferred form of the inventlon, to which I do not wish to be limited, is shown in the accompanying drawings in which Figure 1 is a side elevation of an engine equipped in accordance with my invention; Fig. 2 is an end view thereof; and Fig. 3 1s a sectional view on line aa in Fig. 1.

Like parts are indicated by similar characters of reference throughout the difierent figures.

The invention specifically relates to reciprocating horizontal engines and is of special utility in connection with internal combus tion engines, one form of which is illustrated in the drawings. Engines of this type are so well known that adescription thereof in detail will not be necessary, it suflicing to mention those parts that are in inmediate association with the improved engine base and the relationship of the base to the fly wheel element of the engine.

The cylinder 1 is in this instance shown as being surrounded by a cooling jacket 2 which is in fixed and rigid relation with the cylinder, both cylinder and jacketl being of cast metal and suitably united in a manner well known by those familiar with the art. The crank shaft 3 is journaled in suitable bearings that are carried by an extension of the jacket 2, this crank shaft having propolling torque exerted thereupon and in turn governing the agencies by which such torque is produced, all as is well understood. The cast jacket 2 is provided with two pairs of horizontally outsetting feet .4, 5/ that are cast integrally therewith in close proximity to the cylinder. These feet are rested u the upper longitudinaledges of the boards 6 that preferably slope so as to converge upthe planes of the base boards,

wardly, these boards being of such a height as sufiiciently to elevate the engine to a position in which the fly wheels 7, that are carried upon the crank shaft 3, are clear of the level upon which the bottom longitudinal edges of the boards rest, the horizontal engine overlyin the space between the boards. The ma or portions of the stems of elongated bolts 8 rest against the inner and opposed faces of the boards 6 and are secured to the boards by means of bolts 9, these bolts having inner heads 10 that engage marginal portions of openings passed through the shanks of bolts 8 through which openings the threaded shanks of the bolts 9 are passed. The nuts 11 serve when tightened to cause the bolt heads 10 to clamp the boltsSvery rigidly against the inner opposed side faces of theboards 6,whereby weakening bolt holes need not be formed in the boards. The upper ends of the bolts 8, which are thus very firmly held in engagement with the boards 6, are preferably slightly deflected so as to extend in purely vertical directions and thereby be readily adapted for passage through verticahopenings provided in the horizontal outsetting feet 4 an 5, the upper ends of these bolts being threaded to receive nuts 12 that enable the feet to be clamped into very firm engagement with the top longitudinal edges )of the base boards 6. One pair of outsetting feet, say the feet 4, is provided 1 with downwardly projecting feathers 13 that are received within transverse grooves 14 provided in the tops of the base boards, to insure against creep-age that might otherwise occur tween the baseboards and the balance of the engine structure, as for example in case of the lack of a snug fit between the feet 4 and 5 and the notches in the upper edges of the base boards that receive these feet.

Further to insure the rigid relation between the jacket 2 and the supporting base boards of the engine I empioy bracing elements 15 extending across the space between the base boards from the upper parts of the base boards to their lower parts, these bracing elements being desirably integrally formed with the heads 10 of the bolts 9 as indicated.

Thus there are two pairs of bolts 8, the mem bers of each pair being located substantially in the same plane that is at right angles to the two pairs of bolts 8 being separated longitudinally to a slight extent be- 1 of the base boards, the bolts 8 of each pair being anchored in position by means of bolts 1) whose heads 10 engage the bolts 8 and whose nuts 11 upon the outsides of the base boards firmly clamp the heads 10 against the bolts 8, the head 10 of each upper bolt 9 being rigidly connected with the head 10, of the lower and opposite bolt 9 by a strut 15 which acts as a tension and compression member forthe purpose of holding the base boards in rigid relation. Each element 15 thus forms, with the bolts 9 united therewith, a single bolt structure that includes a shank comprising the strut 15 and the deflected shank portions 9, the elements 10 then being in the nature of enlargements to perform the function for which they are provided, and while I prefer single bolt structure comprising the elements 9, 10, 11 and 15 that are capable of performing their functions individually and collectively I do "not wish to be limited in all embodiments of my-invcntion to such a structural characteristic, nor do I wish to be limited to other details of construction specifically illustrated since changes may be made-without departing from the spirit of the invention.

As is well known, it is desirable to increase the diameters of,engine fly wheels as far as is practicable within limitations imosed by surrounding conditions, in order to decrease the weight of the fly wheels but such an increase in the fly wheel diameter is accomplished by a corresponding elevation of the fly wheel shaft thereby necessitating a correspondingly higher engine base to afford the necessary clearance between the fly wheel peripheries and the level upon which the engine rests. If this base were made of cast iron, as hitherto, its weight would be increased to such an extent as to limit the extent to which the diameters of the fly wheels might otherwise be enlarged. The engine base of my invention is therefore of great utility since wooden boards and a comparatively light truss structure intervening between the same would replace cast iron bases so that the factor furnished by the weight of the engine bases in limiting the extent to which the fly wheels may be increased in diameter is removed.

,Where the invention is embodied "in a hydro-carbon engine, the engine base of my invention affords an excellent housing or support for the fuel oil receptacle 16 which desirably has its sides sloping in conformity with the slopes of the inner opposed faces of the engine base board 6. The fuel oil can or receptacle 16 is located in position after reac es the engine base has been the balance of the engine, this can being pressed upwardly so as to be rigidl engaged between the base boards, wherea er cleats 17 are nailed upon the base boards beneath the fuel can to hold this can firmly in its position. The cleats 17 are provided with upward extensions 18 at their ends to-avoid possible longitudinal movement of the can 16 with respect to the engine base boards 6.

Having thus described my invention, claim as new and desire to secure by Letters Patent the following 1. A reciprocating engine structure including a cylinder and fly wheel; feet located in close proximity to and in rigid relation with the cylinder; engine supporting base boards placed on ed e and upon the upper edges of which said eet rest; bolts clamped at their upper ends into engagement with the aforesaid feet, these bolts havin elongated stems that rest against the baseflioards and having openings therein to enable the same to be clamped to the base boards; u per and lower bolts 9 having their shan s passing through the openings of each of the aforesaid bolts and serving to clamp the aforesaid bolts into engagement wit the base boards; and struts 15 uniting the upper bolts 9 of each of the base boards with the lower bolts 9 of the companion base board.

2. A reciprocating engine structure including a cylinder and fly wheel; feet lo cated in close proximity to and in rigid relation with the cylinder; engine supporting base boards placed on ed e and upon the upper edges of which sai feet rest; bolts clamped at their upper ends into engagement with the aforesaid feet, clamping devices serving-to clamp said bolts to side facesof assembled with I lie the base boards; and bracingbmechanism m- 0 tervening between the base cards.

(3. A reciprocating engine structure including a cylinder and fly Wheel; feet located in close proximity to and in rigid relation with the cylinder; engine supporting base boards placed on ed e and upon the upper edges of which sa'i feet rest; bolts clamped into engagement with the aforesaid feet; and clamping devices serving to ase clamp said bolts to side faces of the boards.

In witness whereof, I hereunto subscribe my name this twenty third day of January LA VERNE W. NOYES. Witnesses:

DANIEL R. Sorrows, Junie M. martian.
