EDWIN BLAKE SMITH, OF MANCHESTER, ENGLAND.
WRENCH.
SPECIFICATION forming part of Letters Patent No. 591,893, dated October 19, 1897.
Application filed February 10, 1897. Serial No. 622,853. (No model.)
T0 at whom it may concern.-
Be it known that I, EDWIN BLAKE SMITH, engineer, a subject of the Queen of Great Britain, residing at Manchester,in the county of Lancaster, England, have invented new and useful Improvements in Spanners or \Vrenehes, of which the following is a specification.
This invention relates to the construction of adjustable spanners or wrenches, and particularly to that class wherein the movable jaw is roughly adjusted by sliding the same by hand, and is then tightened and fixed by a locking arrangement.
On the drawings annexed to this specification, Figure 1 is a side elevation. Fig. 1 is a detail view of the movable jaw with the shank thereof shown in dotted lines; Fig 2, a face view of an improved adjustable spanner or wrench made according to my invention. Fig. 3 is a transverse section of the same, taken through about the line A B in Figs. 1 and 2. Fig. 4 is a similar section through the line C D, and Fig. 5 a section through the line E F. Fig. 6 shows a detail view of the flattened shank; Fig. 7, a crosssection thereof, and Fig. 8 detail views of the nut. Fig. 8 is a detail view of the nut for operating the movable jaw.
The fixed jaw a of the spanner is made of one piece with the side plates 79 forming the shank and handle of the same. The head and handle are made solid by the introduction of filling-pieces c, which are fixed solid between the plates by means of pins or rivets, leaving a slot between the head and the shank in which slides the adjustable jaw d. (See Figs. 1, 2, and 3.) The adjustable jaw d is formed or provided with a tailpiece or mutilated screw 6 of a flattened section, (see detached side view,-Fig. 1, partial elevations, Fig. 6, and transverse section, Fig. 7,) the screwthread being on the edges only, and the tailpiece so formed that it can slide endwise inside the handle, but cannot turn therein. (See also section, Fig. 5.), This tailpiece 6 passes through a nut f, which has a double milled or nurlededge, and is carried between the two plates b of the handle, the milled edges projecting through slots in the plates 6, the narrow strap b between the slots beingbulged or curved so as to embrace the neck of the nut f, as clearly seen in cross-section at Fig. 4., and form hearings in which the nut f can revolve, but not move endwise. It will be seen on the detached plan view of the nut f, Fig. 8, that the central hole of the nut is slotted or elongated in section, so that the screw-threads only exist at two sides, and in one position of the nut the tailpiece e of the movable jaw cl can slide endwise through the nut, the threaded part of the tailpiece sliding clear through the slotted part of the nut, and it will be seen that when the nut f is in this position the movable jaw d can be roughly adjusted to the nut to be operated on, and that while the shank is still being held in the hand the nut can be turned by the thumb and finger so as to bring the mutilated threads into gear and so tighten up and lock the said jaw cl. A line a; is made on the nurled edges of the nut f, and if desired on the side plates of the handle, (see Figs. '1 and 8,). to indicate by either sight or touch when the nut is in the free position for sliding the movable jaw d in or out. I may here remark that, if preferred, the whole adjustment of the movable jaw cl may be eifected by turning the nut f, but I do not consider it advisable to use the same for other than looking purposes, as the rough adjustment is much more readily and quickly performed by sliding the movable jaw and the locking is instantaneous. To prevent any liability of the mutilated threads jamming or butting against each other, I use a V-thread and I bevel or round off the leading edges of the threads on the tailpiece e of the movable jaw and I slope the sides of the slots in the nut f, (see plan view on Fig. 8,) so that there is no liability of the edges to catch against each other.
I claim as my invention- A spanner or wrench having the fixed jaw and shank and handle made of side plates 1) with filling-pieces o inclosing moving jaw cl and its mutilated screw 6 having beveled leading ends to the V-threads thereof double-' IOO
