SFECIFICATION forming part of Letters Patent No. 530,024, dated November 2'?, 1894.

Application filed March 6, 1894.

To @ZZ whom it may concern.-

Be it known that I, PAUL R. DE F. DHUMY,

a citizen of the Republic of France, residing at Chicago, in the county of Cook and State 5 of Illinois, have invented certain new and useful Improvements in the Method of Constructing Armor-Plates and Certain Parts of Machinery, of which the following is a specication.

This invention relates toimprovements in the method of constructing plates which may be used for armor plates for iron-clad vessels, and also for parts of machinery, such as shaftings, crank-shafts, and y-wheels; and r 5 consists in certain peculiarities of the construction, novel arrangement, and form of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.

The objects of my invention are first, to provide a means by which the production or manufacture of armor-plate can be accomplished with a minimum of cost and labor, and in a much shorter time, than by the method z5 ordinarily employed; and second, such a construction, Which with slight changes, is applicable to parts of machinery, such as large shaftings, iiy-wheels, &c.

In order to enable others skilled in the art 3o to which my invention pertains to make and use the same, I will now proceed to describe it, referring to the accompanying drawings, in which-- Figure 1, is a vertical sectional view of a portion of the bodyof a vessel, showing the construction of my armor-plate and the manner of securing the same thereto. Fig. 2, is a detail perspective view of a portion of one of the sections of the plate and a part of its 4o frame. Fig. 3, is a perspective View of aseotion of the plate,showing it secured together and ready for its frame, illustrating a modification therein, and Fig. 4, is a similar view of a section of the plate, showing the exterior and interior plates or caps and connecting parts removed. Fig. 5, is a perspective view of the exterior plate or cap detached. Fig. 6, is a perspective view of the inner plate or cap detached. Fig. 7, is a perspec- 5o tive view of one of the sections of the plate,

showing it ready for its frame, and illustrat- Serial No. 502,484. (No model.)

ing another modification therein. Fig. 8, is a perspective detail view, partly in section, of one of the sections of the plate and its frame, With the exterior cap removed. Fig. 9, is a detail perspective view of the exterior cap used in the modification shown in Figs. 7, and 8. Fig. 10, is a sectional view, taken on

line

Fig. 12, is a view in side elevation of a portion of afly-wheel, embodying my invention. Fig. 13, is a sectional view thereof, taken on line 13, 13, of Fig. l2. Fig. 14, isa plan view of Fig. 12. Fig. 15, is a view in elevation of a portion of one of the spokes of the fly- 7o wheel. Fig. 16, is a similar view of a portion of the hub. Fig. 17, is a similar view of another part of one of the spokes of the iiy- Wheel. Fig. 18, is a view in elevation of another part of the hub. Fig. 19, is a perspective view, partly in section, of a portion of a crank-shaft, showing my invention embodied therein. Fig. 20, is a like view of another part thereof, and-Fig. 21, is a perspective view of a portion of the same.

Similar letters refer to like parts throughout the different views of the drawings.

A, represents a cap or exterior plate of steel or metal of any desired dimensions, but preferably rectangular in form. The inner surface of this plate is provided with a number of transverse grooves a, and corresponding projections d', within which grooves and against the ends of the projections fits and rests a series of alternately wider and nar- 9o rower metal slabs B, which slabs are provided at suitable points with holes b, and b', so that the said holes or openings shall be in a line drawn across the slabs B, or transverse plates.

By reference to Fig. 1, of the drawings, it will be seen that the holes b', in every alternate slab is larger in diameter than the holes or openings b, in the intervening plates. The slabs B, and the plate A, are placed together,

as shown in Figs. 1, and 2, and the frame conroo sisting of a series of slabs or sheets C, in the shape of nested boxes is placed around the same, and the exterior plate A, is held in position by means of the bolts C', which pass through the sides of the frame C and through registering holes in the projections a' and wider slabs B. The rear portion or opposite side of the frame C, from the plate A, is provided with openings or seats c, for the reception of bolts D, which pass through the backing D', and are secured within the hull of the vessel. The frame C, is also provided at suitable points to correspond with the openings b, and b', with similar openings b2 through which melted metal is poured into the openings b, and b', of the slabs B, Where when it becomes cool it will join the slabs into a compact and almost solid mass. Between the rear side of the frame G, and the backing D', is placed a series of tubes E, havin g within them similar tubes E', between which is placed suitable packing. These tubes are to furnish resistance to the force of the projectile thrown against the plate A, and as is Well known greater strength is attained by the cylindrical form of the tubes, and by having one within the other, if the outer one should become broken, the' inner one will still resist the force. It is obw'ous that if the plate A is destroyed by a projectile, it can be readily removed, and a new one replaced. It is also obvious that by employing the series of slabs B, placed transversely with the plate A, greater strength is acquired, and as the slabs are divided one from the other, that the force of the projectile striking against the plate A, will be distributed, and thereby rendered less effective. The frames C, are united together on their inner surface by means of suitable bolts C2, or in any desired manner.

In Figs. 3, to 6, inclusive, I have shown a modification of the construction of the armorplate, in which the alternate slabs B', are fitted into grooves a, of the plate A', as above described, and aresecu red together by means of bars B5, extending across the group of slabs at points preferably about midway between their front and rear ends; while the projections of the. exterior plate or cap A'v may be secured to the wider slabs B' by plain bolts or keys, or by means of meltedk metal inserted in the openings a2, passing transversely therethrough. That portion of the slabs B', in this modification adjacent to the vessel is provided with a cap or interior plate A2, having recesses a3, and corresponding projections a4, which unite with projections a5, and recesses a6, at the rear edges of the slabs. Transversely to the said recesses and projections the slabs are formed with recesses a7, within which tits the transverse extension as, on the interior cap A, or plate. When the caps or plates A', and A2, and slabs B', are united, as shown in Fig. 3, they will form a compact section, which may be inclosed in a frame, as before described and secured to the vessel.

In Figs. 7, to 10, inclusive, is shown still another modification, in which the slabs B2,

are placed transversely against the in ner su rface of a series of slabs A3, which form the exterior plate in this case, and which latter named slabs are formed with grooves a, and for the reception of the ends of alternate slabs B2, as shown. The slabs B2, are held together by means of bars or melted metal inserted in the openings e, which unite them together, and with the inclosing frame C, or box. The series of slabs A3, forming the exterior cap or plate is secured to the series of slabs B2, by means of bars or melted metal d5, Which are passed transversely through the openings d6,in the projections di, of the slabs B2; and around the united parts may be placed a frame C as before.

In Fig. 11, is shown another manner ot' securing the plate to the transverse slabs, which consists in forming the plate A4, with dovetail mortises. c5, Within which is fitted correspondingly formed projections f, on the ends of the transverse slabs.

In Figs. 13, to 18, inclusive, I have shown the method of employing my invention to the construction of the various parts of a iiywheel, which consists in laying a series of strips of metal of the requisite form, to form the periphery of the wheel, the spokes, and hub thereof, and providing said strips with openings, through which is passed bars or melted metal for securing them together.

In Figs. 19, to 2l, inclusive, is shown portions of a crank-shaft, in which the same method of construction is employed, as above described in the fly-wheel.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
