H. D. MELENDY. SPOOL.
N'0. 408,732. Patented Aug. 13, 1889.
UNITED STATES HERVEY D. MELENDY, OF NASHUA, NEW HAMPSHIRE.
PATENT OFFICE.
SPOOL.
SPECIFICATION forming part of Letters Patent No. 408,732, dated August .13, 1889'. Application filed June 13, 1888- 'S'erial No. 277,002- (No model.)
To all whom, it may concern:
Be it known that I, HERVEY D. MELENDY,
' a citizen of the United States, residing at Nashua, county of Hillsborough, State of New Hampshire, have invented a new and useful Improvement in Spools, of which the following is a specification.
My invention relates to improvements in spools which have their heads and cylinders made of separate pieces of'wood andthen fastened together, but more particularly to such as are subject to great longitudinal strain and the heads of which are liable to pull off, such as are used for the winding of wire, where the tension is relied upon to straighten the wire, and for Winding strong linen, cotton, or silk yarns or threads.
Heretofore much trouble has been experienced in making strong connections between the heads and barrels or cylinders, and various devices have been in use. The common method of fastening is by means of a thread cut on the ends of the cylinders which engages a corresponding thread cut in the hole in the head when the head is screwed onto the cylinder. Heads fastened in this manner come off from stripping of the thread. Another method is to make a taper or flaring hole through the head, and after placing the head on the cylinder expand the end of the cylinder by driving a taper plug into a hole in the center of the cylinder. Both this method and that of screwing on are quite liable to split the head, particularly if the head is of a single piece of wood out either with or across the grain. Another method is to use a head with a tapering or flaring hole, a straight cylinder, and filling-the open space with an annular wedge driven between the cylinder and head. This method is faulty in that the head easily comes off when the glue from any cause gives way. Still another method is to out an annular groove in the head, the groove being the widest at the bottom, into which groove the end of cylinder is driven, first having an annular groove cut in its end, and into which an annular wedge has been lightly inserted in such manner that before the end of the cylinder reaches the bottom of groove in the head the annular wedge comes in contact with the bottom and is forced up into the groove in the cylinder, thus expanding the end of the cylinder inside the hole in the head and making a dovetailed joint. This fastening is not as strong as mine, as it engages only a portion of the thickness of the head and is obj ectionable, as it causes a break in the inside bore of the spool where the wood of thehead and cylinder should come together, thus making the bearing of the spool upon the spindle irregular and uneven, causing dirt to attach itself to the inside of the spool.
I11 the accompanying drawings, Figure 1 is an elevation of the spool. Fig. 2 is an end view of the same. Fig. 3 is a View of a section cut through the center of the spool, showing the diiferent parts ready to be put together. Fig. 4 is a view of the end of the spool with a section cut away to show the coilnection of the head with the cylinder in the finished spool.
Similar letters refer to similar parts in the different views.
A is the head.
B is the hole in head.
0 is the cylinder.
D is the annular groove in end ofcylinder.
E is the annular wedge.
F is the spindle-bearing.
The heads maybe of one or more pieces, with the grain of the wood running in line with the cylinder or at right angles to it.
I first bore a hole X through the head A, which hole is then made tapering the whole or a part of its length, as shown in Fig. 3, B. The end of cylinder 0 is turned to the same diameter as the smallest part of hole in head and in its end an annular groove of suitable depth is made, as shown in Fig. 3. The head is then crowded onto the cylinder, as shown in Fig. 3. Then the annular wedge E is forced into the annular groove D in the end of the cylinder O, expanding the outer shell of the end of the cylinder until itfills the space in the head, as shown in Fig. 4, making a so-called dovetail fastening. Glue can be used in the several constructions, if desired, but it is not absolutely necessary. This construction leaves the spindle-bearing F continuous and free from breaks or joints, and it will be seen that the heads cannot be pulled off by longiinder end and expanding the cylinder end to fill the hole in the head, substantially as described.
2. The combination of the head A, having the tapering hole 15, the cylinder C, having the annular groove D, and the annular wedge E, substantially as and for purposes described.
HERVEY D. MELENDY.
