Improvements in Automatic Weighing’ Machines. We, Edward Henry Beckett, of Glen-eu-lan, Tan-y-grisiau, in the County of Merioneth, North Wales, and Charles Warren Roberts, of Plas Weunydd, Blaenau Festiniog, in the County of Merioneth North Wales, Engineers, do hereby declare the nature of this invention to be as follows :— 5 First, certain details in the construction or arrangement of the dial indicating mechanism, and secondly, certain details in the construction or arrangement of mechanism whereby the weight of persons or articles, on the platform, is auto¬ matically registered and permanently recorded. To carry our invention into practice, and as we show in the annexed drawings of 10 which Figure 1, Sheet 1, is a front elevation, showing the indicating mechanism in its normal position, and, Figure 2, Sheet 2, is a back elevation showing the release action. This is also in its normal position and corresponds with the front elevation, Figure 1. 15 The invention consists of a central rod A. which is provided at its upper end with a toothed rack B. which gears into a toothed wheel C. The wheel C. is fixed to a spindle which carries the dial pointer at its outer end. The lower end of the rod A. runs free into or over the rod D. and is fitted with an adjustable stop Z. This rod D being connected to the levers of the platform 20 in the usual way. The rod A. is free to fall by its own weight and is guided by the guide rollers E. When A is in its normal position, it is retained by the catch F which slips under the noggle or lug G, this noggle or lug being fixed on the back of the 25 rod A. The catch F. is fixed on the spindle H. and is held up to its work by the lever J. and the counterpoise K. The spring finger L. is secured at one end to the rod A. and the other or outer end is provided with a pencil. 30 The reels or drums M. and N. are set and revolve on the vertical spindles O. & O. A coil of paper or metallic tape is wound on the reel or drum M. and the loose end made fast on the reel or drum N. so that the said tape may be wround from the one on to the other. The levers P. and Q. are fixed to a spindle R and form a bell crank. 35 The out end of the lever Q is forked and rests on the pin S fixed in the rod A. The top end of the lever P. is connected to the rod T. The end of the rod T. is fitted with a moveable finger U. which gears into a ratchet wheel V. fixed on the reel N. W. is a counter connected to the top of the rod A. by means of the connecting 40 rod X and registered a unit for each descent of the rod A. Y. is the weigh spring, and receives the weight from the platform through the rod D. The action of the machine is as follows. A certain body or weight to be accertainerl, is placed on the platform in the 45 ordinary way. The said weight being transferred to the spring Y. through the ordinary platform levers, and the rod D. The spring Y is compressed a certain distance the rod A being retained in its normal position by the catch F. [ Price 8<f.*|
