T-HEOPHILES LUOIER, OF DETROIT, MICHIGAN.

BOW-FACING OAR.

SPECIFICATION forming part of Letters Patent No."6l1,4 97, dated September 27, 1898. Application filed November 22, 1897. Serial No 659,463. (No model.)

To all whom it may concern:

Be it known that I, THEOPHILES LUOIER, a

citizen of the United States, residing at De- In the drawings, Figure 1 is a plan view of a boat to which my oars are applied. Fig. 2 is a perspective view illustrating the connection between the handle and blade sections and the oar-lock. Fig. 3 is a horizontal sec tion therethrough. Fig. 4 is a plan of the,

blade-section.

A is the handle-section, and B is the bladesection, of my improved oar. The handlesection comprises the handle a, having a bifurcated stem or loom, preferably formed of the separated bars 5 and 12, secured to the handle at one end. The blade-section consists of the blade 0 and a bifurcated stem or loom, similarly formed to the handle-section of separated bars at d.

O and C are gear-segments secured, respectively, to the bifurcations of the handle and the blade sections, preferably by providing each segment with the sockets f, with which the ends of the bars 19 b and d d are respectively engaged. 4

D is a frame in which the segments 0 and C are pivotally secured, so as to be in mesh with each other, said frame thus forming a connection between the two sections of the oar and also the oar-lock connection to the gunwale of the boat. ably formed of the two plates 9 and g, arranged parallel to each other on opposite sides of the segments and connected by the lugs h and h. The lugs 71. extend across in the triangular spaces on opposite sides of the segments andthe lugs 77. in the spaces between the bifurcations of the oar and blade sections, respectively, beyond the pivot pins 2', in which said segments are journaled.

In order to permit of the two sections of the oar being folded together, as shown in Fig. 3,

The frame D is prefer the sockets f, in which the bars I) b and (1 cl are secured, are arranged within the circle of the segments, so as to leave a space E between the sections when folded together sufficient for the lugs h. The spokes or web connecting the rim and hub of each segment is also cut away on each side at F, so as to permit of the full stroke of the oar without interfering with the lugs 71.

G are lugs or cars in the lower plate g", which are pivotally secured to cars II, secured to the gunwale of the boat.

In practice the oars thus constructed are secured, as described, to the boat. The oarsman may sit facing the bow of the boat, and by manipulating the oars in the usual way he will propel the boat in the forward direction.

The construction of my oar is designed to secure at once strength, lightness, and simplicity. Thus the bifurcated stem or loom on each of the sections, in connection with a socketed segment secured thereto, forms a trussed structure which greatly increases the strength of the oar. The frame D is also strengthened by the four points of connection between the plates g and 9. Both the frame and the segments may be formed of simple castings, the lugs hand h being cast integral with the plates 9 and g, so as to match each other, and being bolted or otherwise secured together. The sockets f are also cast integral with the segments.

The bars I) b and cl d are preferably made of separate'pieces suitably spliced to the handle a and blade 0, as shown in Figs. 8 and 4:

of the drawings.

What I claim as my invention is- 1. In a reverse-stroke oar, an oar-section comprising a gear-segment and a loom secured thereto consisting of separated bars secured to said segment at one end, connected to a single section at their opposite ends, in combination with a second oar-section provided with an intermeshing gear-segment, and'means for securing the two sections together.

2. Ina reversestroke oar, an oar-section comprising a gear-segment having sockets formed thereon, and aloom consisting of separated bars engaging with said sockets at one end and connected toa single section at their opposite ends, in combination with a second secured to the=bifurcations of said handle and blade sections respectively, and a connecting-frame to Which said segments are pivotally secured comprising plates on opposite sides of said segments and connecting-lugs or cross-bars therefor extending between the bifurcation of said oar and blade sections.

In testimony whereof I affix my signature in presence of two Witnesses.

THEOPI-IILES LUCIER.
