DlPPER-HANDLE.
SPECIFICATION forming part of Letters Patent No. 745,329, dated December 1, 1903. Application fled April 4:. 1902. Serial No. 101,328. (No model To aZZ whom it may concern:
Be it known that I, BARTON I-I. COFFEY, a citizen of the United States, and a resident of New York city, in the county of New York and State of New York, have invented a certain new and useful Improvement in Dipper- Handles, of which the following is a specilication.
This invention relates to the dipper-handles of excavating ordredgin g apparatus, land or marine, and has for its object the provision of a strong and durable handle that will not bend under the strains incident to its work and will last long or resist wear from clamps and guides.
Prior to the present invention clipper-handles of the class to which this invention relates have been made of one or two sticks of solid timber, according to the particular kind of apparatus they were to be used'with, such sticks being long and squared in cross-section.' Such handles have objectionable features, such as splintering or splitting, grinding up of the bers where the clamps Aand guides act, and a rather short life, thus adding to l the expense of operation.
In the practice of the present invention I sometimes take sticks of timber of suitable cross-section, rabbet them along two sides for the reception of the flanges of channelirons, form a trough from two channel-irons and two sides of plate metal, place the stick in the same, and then put a second channeliron in place and bolt the Whole together, or I may replace lthe stick of timber by one or more channel-irons riveted to the side plates, thereby stiffening the latter against the crushing action of the guides and clamps commonly used in machines of the class to Which this invention relates. The channelirons are preferably each an integral iron; but compound or built-up channels may be used without departing from this invention.
The invention is illustrated in the accompanying drawings,forming part of this specification, in which- Fignrel is a front elevation, and Fig. 2 a side elevation, of a dipper-handle in which the invention is embodied. Fig. 3 is a crosssection of one form of the handle. Fig. fi is a cross-section of another form of the handle forming the present invention. Y
In the drawings the reference a indicates a dipper or bucket, b the handle, which is formed of two parallel bars c, having a iiller d between them for a distance up from the clipper a, and e is the usual chain.
, Reference f designates rods by which the dipper is secured to the handle.
Each bar c comprises a plurality of channelirons g, side plates h, riveted or otherwise secured to the flanges of the channels g, the rivet or bolt heads being bypreference flush with the exterior surfaces, and a filler or strengthener within the box-like reinforce formed by the channels and plates. Such filler or strengthener may be a stick of timber i, as in Fig. 3, or a central channel-iron g, as in Fig. 1i. It is remarked that when the boxform is lled, as in Fig. 3, the timber need not be a single stick sufficiently large to fill up the box; but it may be made up of side-by-side pieces held in place by'suit-able means, as bolts or through-rods. In case any of the channels have their flanges pointing outward, as in Fig. 4, the channel is filled with a piece of timber iX, which is bolted or otherwise secured in place.
The invention may be embodied in forms other than those shown in the drawings and hereinbefore described.
l. A dredging dipper-handle consisting of channel-irons, plates secured to the flanges thereof, and means for preventing transverse crushing thereof, substantially as described.
2. A dredging dipper-handle consisting of a plurality of parallel channel-irons, and metal plates secured to the Ilan ges thereof, substan- Signed at New York, in the county of N ew tially as described. York and State of New York, this 2d day of 3. A dredging dipper-handle consisting,` of April, A. D. 1902. a stick of timber and Wearing-irons along its 5 angles and sides, substantially as described.

4. A dredging dipper-handle consisting of a plurality of parallel channel-irons, metal lVitnesses: plates secured to the flanges thereof, and a A. C. WALKER, tilnber-lling inclosed by said channels and ADOLPH F. SCHMIDT. 1o plates, substantially as described.
