3630 W. WALKER and E. HOLT. Improvements in directacting double-action steam pumps. Dated December 21, 1867. Here the inventors employ, according to one arrangement, a horizontal steam cylinder and pump barrel cast to foundation plate, and they connect together the piston of the cylinder and plunger of the pump, and also the steam slide and water valves. The body of the piston and piston rod are of one piece, and the rod is of enlarged diameter; so that there can be an internal bore in the piston and rod for about the length of the stroke. In this bore they place a small piston, the rod of which passes through the main piston and one of the covers of the cylinder, and is jointed

to one arm of a two-armed lever, the other arm of which

is jointed to the slide rod, and in the bore of the piston is fixed a ring or plate encircling the small piston rod. As the piston is arriving to one end of its stroke, the ring or plate comes in contact with, and gives motion to, the small piston, so as to give motion to the two-armed lever, and give one traverse to the slide, and when the piston is arriving to the other end of its stroke the bottom of the internal bore acts on the small piston and gives reverse motion to the two-armed lever for causing the slide to

3641 W. DIXON and W. BROWN. An elastic coupling for
the prevention of sudden or undue strains upon ropes or chains,
when used in towing, hauling, or lifting. Dated December 23,
1867.

This apparatus consists of a wrought-iron frame of a
suitable shape in which is placed one or more drums
keyed fast on to a shaft or spindle, so as to revolve with
it. To this spindle or shaft are attached spiral springs in
such a manner that, when the drums are made to revolve,
the springs are thereby compressed. A smaller frame is
fitted loosely within the main frame, and has attached to
it the hook by which the rope or chain to be used for
drawing or lifting can be fastened. This smaller frame
carries one or more smaller drums or sheaves. Ropes or
chains of a suitable length aro fastened to the large drum
or drums, and wound three or more times round them;
they are then led over the smaller drums or sheaves, and
then secured to the top shackle of the main frame. If
any sudden strain comes upon the hook on the smaller
frame, it will cause the large drum or drums to unwind,
and thus act on the spiral springs; by these means the
ropes or chains used will be relieved of the sudden shock
to which they would be otherwise subject.-Patent aban-

3651 M. J. RICE. Improvements in machinery for cutting and heading nails. Dated December 23, 1867. This invention has reference to a former patent, dated November 10, 1866 (No. 2942). The first part of the present invention consists in mounting the heading dies upon independent slides carried by the oscillating or semirotating cutter frame described in the specification of the patent before referred to. Each heading slide is connected by a knuckle, or other suitable joint, to a lever on each side of the machine, such levers being actuated by connecting rods and eccentrics (or by other mechanical means) on the main driving axis of the machine, the headers and slides being so arranged as to be capable of adjustment to each other. The second part of the invention relates to the arrangement of the gripper, or grippers, which consists of a slide actuated by a lever, but disconnected therefrom, the slide being moved out of action by a spring. The lever for actuating the gripper slide is mounted on axes on the oscillating frame, and receives motion by means of a cam on the main driving axis. The third part of the invention consists in imparting an oscillating or semi-rotating movement to the cutter frame with nipper grippers and headers mounted thereon by means of a spur wheel on the main driving axis which takes into and drives another spur wheel carried by and revolving on a stud on the cutter frame, or connecting rod attached to a crank pin on the last-named spur wheel and to a pin joint on the frame, imparting an oscillating movement thereto, the amount of such movement being capable of adjustment as required. The fourth part of the invention consists in so arranging the feed-plate or frame that the end nearest the cutter can be turned up on a joint, or be otherwise readily removed, so as to enable the workman to get at the cutter or gripping tools without removing the feed frame from the machine. The feed frame is also arranged according to this part of the invention as to be capable of having its elevation and the angle at which the nail plate is fed up to the cutter readily adjusted, as may be required. Lastly, the invention consists in so arranging machinery of this character that the cutter headers, nipper, and grippers, together with the

oscillating frame, are all actuated by means of one driving the rack, and below this rod a second connecting rod is shaft or axis.-Patent completed.

3656 C. POTTINGER. Improvements in motive power engines, part of which improvements are applicable to the arrangement and construction of pumps for raising and forcing liquids, fluids, and other substances generally. Dated December 24, 1867. This invention relates, first, to a novel arrangement of motive power engine of the class known as rotary engines, and consists in the use of a cylinder in which a revolving piston is placed, the part of the piston against which the steam or other motive agent acts being packed so as to closely fit the space of the cylinder in which it revolves. The cylinder is provided with ports or passages in communication with both sides of the projecting part of the revolving piston, on one side of which the motive agent for driving the engine is admitted, and on the other or opposite side, and through the opposite passage or passages, it escapes or exhausts. The passages are provided with a valve or valves which is or are opened and closed

3665 S. and F. LENNARD. Improvements in the manufac-

According to this invention, in order to produce a fabric
with broad ribs, each requiring two or more needles for
its production, the patentees arrange the machine to lap
the threads not in every needle, as heretofore, but in the
following manner:-For one course, say, the front course,
the threads are lapped over several adjacent needles, as
many as are required to make the front rib; next to them
produce the space between the front ribs, and beyond
a number of needles are left without lapping, sufficient to
other needles are lapped to produce another rib, and so
on. Then, in the back course, only those needles are
lapped which are opposite the spaces where in the front
course the needles were not lapped, and these needles
produce the back rib, so that, as will be seen, wide ribs are
now produced, such ribs being each the product of several
needles carried by one bar. In order to lap the threads
on the needles in the manner described, in place of using
patentee use three sets of guides, one set working with
the needles of one bar only, another with the needles of
the other bar only, and the third working with needles of
both bars. The guides in each set may be carried by two

the needles are not lapped, the needles themselves may be
omitted from the machine.-Patent completed.

The only SILVER MEDAL awarded at the PARIS EXHIBITION of 1867 for WOOD-WORKING MACHINERY in the British Section, and the

PRIZE MEDAL of the INTERNATIONAL EXHIBITION, 1862,

THE "GENERAL JOINER."

THIS exceedingly useful machine was invented by S. WORSSAM and CO., and performs nearly all the various kinds of work usually done by hand in a Joiner's Shop, such as Sawing, Planing, and Thicknessing, Mortising, Tenoning, Cross-Cutting, and Squaring-off, Grooving, Tonguing, Rabbetting, Moulding, Beading, Chamfering, Boring, Wedge-Cutting, and many other operations. With a little practice any joiner can work it, and with the aid of a man and boy it will to the work of at least fifteen men.

CAUTION.-The great reputation which the "General Joiner" now enjoys has caused may spurious imitations of it to be made by other Manufacturers, all of whom, however, have overlooked most of the details in its construction which are essential to its success. S. WORSSAM and CO., therefore, strongly advise those who think of purchasing a "General Joiner," to see the Original Machine at work before purchasing any of the spurious copies.
