Title: Improvements in Pneumatic Hammers and Valve Mechanism therefor
Inventor: PAYTON WALTER
Filed: 1900-05-09
Granted: 1901-08-09
Abstract: 8550. Payton, W. May 9. Percussive h a n d t o o l s. - Relates to percussive tools for chipping &c. The shoulder g, Fig. 6, of the tool shank G bears against the end of the tool-holder F, which is pressed inwards by a spring f<1> and struck inter mittently by the vibrating piston A. The motive fluid enters the cylinder by the handle c<2> and tube c<3>, and is controlled by a valve worked by a workman's thumb. This valve consists of a hollow plug E, which screws into the bush e and is provided with holes e<4>, which may be made to register with similar holes in the bush e. The piston in every case contains a hollow valve B, which slides within it with a certain amount of friction caused by the spring ring b<3>. The valve is shifted by striking against the tool-holder or the rear end of the cylinder or a collar D, Fig. 2, either directly or by means of a push-pin b<5>. In the forms shown in Figs. 2 and 6, the piston is of different diameters, the larger diameter being in front. In the form shown in Fig. 2, an intermittent pressure acts on the front of the piston and a constant pressure on the rear. The space in the valve is always supplied with live air, which enters at the rear end of the cylinder During the forward stroke air acts on the rear of the piston and on the area X, while the air in the front of the piston is exhausted first through the opening c<6> and then through the channels a, neck b<1>, and openings a', c'. The valve is shifted by the contact of the shoulder of the sleeve D with the flange b on the valve. During the rear stroke, air enters in front of the piston through the valve and channels a, while the smaller area at the rear of the piston is still acted on by the live air. The valve is shifted back by striking the end of the cylinder. Cushioning is effected at Y. In the form shown in Fig. 6, a variable pressure acts on the front of the piston and a constant pressure on the shoulder Y, the space X being always in communication with the live air. During the forward stroke, the space in front of the piston is in communication with the exhaust through the valve B, openings a', space Z, and opening c<8>. During the rear stroke, air enters in front of the piston through the ports a<3>, b<6> and the hollow valve B, the rear of the piston being always connected to the exhaust. In a third form, the smaller diameter of the piston is in front, and there is a constant pressure on the shoulder of the piston and an intermittent pressure at the rear. In a fourth form, the piston has the same diameter throughout, and there is an intermittent pressure at each end. In this case the sliding tubular valve B has a diaphragm across the middle. The ports and passages are varied to effect these changes of pressure.

Title: Improvements in the Automatic Changing of Shuttles in Looms when the Shuttle-spool is Empty.
Inventor: LOETZSCH OSKAR
Filed: 1902-05-05
Granted: 1903-07-04
Abstract: 10,304. Loetzsch, O. May 5. Loom shuttle-changing mechanism; shuttles; picking-mechanism.-The exhausted shuttle is ejected from the outer end of the shuttle box, and a full shuttle is introduced into the shuttle race, from a shuttle magazine, by a special picking- apparatus. The shuttle, Fig. 3, has a spring a with a hooked part b pressing against the weft, so that when the weft is nearly exhausted, the spring projects from the shuttle. When the nearlyexhausted shuttle enters the shuttle box to the left, the spring a moves a tongue on the front of the box, and the motion of the tongue is transmitted to an anglelever on the lay and at the magazine side of the loom by means of the weft-fork mechanism, the weftfork being connected by a cord to a rocking lever which strikes the angle-lever during the return stroke of the batten. The shuttle box at the magazine side of the loom has no end wall, so that the exhausted shuttle can be ejected from it provided the picker is raised out of the way. In order to allow this to be done, the picker-spindle n is connected to a slide-bar p, formed with a notch engaging with the above-mentioned anglelever ; the bar p is also formed with an extension engaging periodically with a fixed stop s. A notch in this extension engages periodically with the shuttle magazine. When the angle-lever is released, on exhaustion of the weft, the extension is held by the stops s, temporarily, and as soon as the lay has moved back far enough to allow the shuttle to be picked to the magazine side of the loom, the extension is released, whereupon the slide-bar p is raised by a spring and the shuttle is thrown out. At the same time, the notch in the extension engages with the magazine and the lay and magazine are coupled together. The special picking-apparatus for picking a full shuttle from the magazine comprises a picking-lever w actuated from a shaft 8 carrying a pulley 14 connected by a belt 13 to the lever w. The usual picking-stick 3 is actuated by a shaft 4 in line with the shaft 8, and a clutch 6 is interposed between the shafts, and can engage with an eccentric 5 on the shaft 4, or with a disc 7 on the shaft 8. The clutch is actuated from the magazine by means of a chain or belt and fast pulleys. When the shuttle-changing operations have been completed, the slide bar p is depressed, and the magazine thereby uncoupled, by means of an eccentric 10, connected by a chain to the slide-bar.

Title: An Automatic Life Guard to be Attached to Electric Cars.
Inventor: PALMER ERNEST
Filed: 1902-09-25
Granted: 1903-07-30
Abstract: 20,886. Palmer, E. Sept. 25. Obstruction-removers.-A life-guard for attachment to an electric car is formed by a barred or netted frame G pivoted to brackets H on a transverse beam F, in such a manner that it tends to fall into the position shown in dotted lines in Fig. 1. It is normally retained in the position shown in fall lines by an elbowed pin J connected to it at I and mounted in a vertical guide, so as to bear against the underside of a quadrantal plate D, which is pivoted to a bracket E on the beam F and is connected by a rod B to a barred frame A suspended from the front of the car. If the frame A strikes an obstacle, it moves backwards and turns the plate D until a slot in the plate cones over the pin J, thus allowing the guard G to fall and pick up the obstacle. The weight of the obstacle, coming on the rear part of the guard, returns it to its original position, and thus allows the frame A also to resume its original position. Lugs C<1>, C<2> forming attachments for the rod B are capable of double movement, so as to prevent the oscillations of the car from dropping the life-guard.
