RATCHET-BRACE. — Friedberger.— No. 27,653, dated 19th December, 1908. —According to this invention a ratchetbrace is provided with a ratchet device which is easily detachable. An ordinary ratchet spanner is employed which fits over a hexagonal portion of the brace and abuts against a shoulder formed thereon. The spanner is held in place by a nut which screws on to a reduced portion of the brace.
BODY FOR MOTORCABS.—Savers. —No. 774, dated 12th January, 19O9.— According to this invention a limousine type of body is constructed so that it may be opened in a similar manner to the landaulette type. The roof of the body is made in two parts, one part being hinged to the permanent portion of the roof and the other part hinged to the back panel. The back panel is itself hinged immediately above the rear seat, so that it may be swung back into the position occupied by the folding portions of the landaulette body. The aide windows are carried in sliding sashes, which are lowered in the well-known manner. In order to assist in returning
the back to its normal pusition, a rod is pivoted at one end to the lower portion thereof, and at the other end is connected by a link to the body. A spring is secured to the rod where it joins the link, and is also secured to the bottren of the body. When the body is opened, the spring is placed in tension, so that it will greatly reduce the power necessary to return the body to its normal position.
BALL BEARINUS.—Couk and Another.—No. 5,923, dated 11th March, 1909.—This invention relates to dustproof hall bearings which may be readily applied to the axles of heavy motor vehicles or railway cars, and it has for its object to provide a bearing in which the number of balls and races may be increased according to the load to he carried. The inner-race rings are keyed to a bushing which is adapted to be slid over the axle. The outer-race
rings are keyed to a sleeve or cover, which is provided at one end with a single notch and at the other end with a number of notches that extend round the whole circumference of the sleeve. [he end-race rings are screwed into this sleeve or cover, and have two diametrically-opposite flat surfaces over which similarly-shaped washers are slid. These washers have projecting lugs which engage the notches provided in the sleeve or cover so as to lock the end-race rings. The end-race rings have a reduced screw threaded portion on which are screwed ditst-proof caps. When it is required to tighten the bearing, the washer, on that end of the sleeve which is provided with a number of notches, is removed and the end-race ring screwed up, the washer is
then replaced so that its lug will engage a fresh notch and thereby lock it in its new position. It will be seen that, by providing a longer bushing and a longer outer sleeve and duplicating the race rings, the bearing may be considerably extended or lengthened.
WHEELS WITH DETACHABLE RIMS OR TIRES.—Killen.—No. 16,839, dated 11th August, 1908.—According to this invention a wheel is made up of two dished steel stampings, one of which is adapted to fit over the other. Between these stampings a suitable filling material is arranged, preferably wood. The tire
is slipped on to the circumference of the outer dished steel stamping and is secured by means of bolts that extend through the feline of the wheel into the Lire. Suitable holes are bored through
from the faces of the wheel, and these are lined and faced with suitable steel sleeves or tube rivets in order to increase the lateral stability of the construction. The ease of attachment of the tire is one of the principal claims.
ALUMINIUM SOLDER.—Stalder and Others.—No. 23,779, dated 6th November, 1908.—This invention relates to a composition for soldering aluminium. The solder consists of equal parts of zinc and tin, and the flux used with this composition is pure sulphur. The articles to be soldered are heated to the inciting point of sulphur and the soldering process is continued in the usual manner.
DIGGING AND SOWING MACHINE.—Klaus.—No. 13,795, dated 29th June, 1908.—This invention relates to motor-driven digging and sowing machines. Two rollers support an underframe on which is pivotally mounted a. second frame which can be
adjusted vertically, relatively to the underframe. The second frame carries a crankshaft, which is situated between the rollers and on which are mounted connecting rods which operate a number of shovels through suitable mechanism. The crankshaft is driven by suitable means from a motor which is arranged at one end of the underframe, and a seed box or reservoir is situated above the underframe between the rollers. On the crankshaft being rotated the shovels are operated so as to dig into the ground
and turn the earth over when the seed may be sown, and on the vehicle moving forward the second or rearmost roller presses the earth back over the seed. The second frame is connected by means of chains with a spindle on which is mounted a hand wheel, so that, on turning the latter, the frame, together with the digging mechanism, can be raised clear of the ground.
