Component parts of all kinds of machinery and accessories. Below is a cutting of an article which appeared in "THE IRONMONGER." "We have recently had an opportunity of examining an interesting case of samples of small screwed wares offered in this country by C. MEIER-MATTES & Co., of Cannon Street Buildings, London, E.C., who represent Swiss manufacturers of repetition work. Primarily the firm is concerned with the production of high-grade screws for watchmakers, scientific instrument makers, and engineers, and the capabilities of its plant range from watch screws, so small that it is scarcely possible to see the threads on them, up to engineers' bolts and studs as large as 2 in. diameter. The firm does not hold stocks of the screwed products, but is prepared to make quotations for the requirements of users of screwed work of any kind. A particularly interesting range is the brass wood screws, cut in the lathe. They are supplied in a variety of sizes up to No. 5 in. gauge, and as long as 1 1/2 in. with round, csk. and csk. domed heads. These are finely cut with a self-centring and self-entering point, and while they do not compete with the ordinary article, the makers claim that they are superior to them for fine work. Apart from screws pure and simple, the samples submitted to us included small screwed fittings, such as brass lubricators produced from the bar, Stauffer lubricators, and the bodies of 'pet' lubricators, which would require to be fitted with hinged or slip-on caps, as the case might be. There were also parts for electrical fittings, cycle-tube valves, and other accessories, and aeroplane strutting links. An interesting patented appliance is the 'Flury' Cable Connector, which was designed for connecting the wires of overhead high tension cable, and is supplied in a range of sizes to carry from .35 cm. to .60 cm. diameter wire. This device consists of a twin brass barrel connected with a main screw. Each half is fitted with a slotted cone collar screwed inside. The two ends of the cable to be connected are brought into the cones with the sleeves slipped over the ends. Then, when the whole is tightened up, pressure is brought to bear on the slotted end of the sleeve, which tightens everything in the body of the connector. The device is extremely simple, and experiments conducted at the Zurich Federal Polytechnic seem to show that the tensile strength of a connected cable is practically the same as that of the cable itself; in some tests it was slightly higher, and in others slightly lower." NOTE.—Our Cut-thread Wood Screws (brass only) are now not necessarily dearer than ordinary pressed ones. Some small dimensions are even cheaper. We do not specialize in Engineers' Bolts and Nuts, or ordinary Whitworth Screws and Nuts, requiring no special finish. We have at present certain stocks of B.A. Screws, Sparking Plugs, Ceiling Rose Plates, 5 amp. Switch Terminals, Reducing Nipples, Adaptor Pins, etc., in order to give clients small supplies to go on with, whilst the bulk is coming up from Works. Send us samples or designs.

A friend of ours bought a screw-driving machine, but soon discovered that "jamming" which occurred pretty often, and meant each time an interruption in the working of the machine, robbed him of some of the extra profit he had anticipated by substituting machine for hand-work. Going into the question he found that the jamming was due in almost every case to the diameter of the head of the screws he was using not being sufficiently accurate. HE IS NOW USING OUR SCREWS, i.e., cut screws of extra high quality, instead of rolled or pressed ones. There is practically no more jamming of the machine, and therefore increased output and more profit. Are you using Rolled Thread Screws? If so, it will pay you to investigate and to find out how much potential profit you are losing by (a) Jamming, if you use screw-driving machinery ; (b) Throw-out screws, broken threads, faulty heads, etc., and loss of time caused thereby. If you will let us know what size screws you are using, and for what purpose, we shall be pleased to give you detailed calculation showing how much more profit you would make by using our screws. Accuracy no Luxury. Another friend of ours was in the habit of buying pressed Switch Dollies. Some were satisfactory, some were not quite round, and some had the hole not quite in the proper place. But they were cheap. Contractors and Electrical Engineers often noticed that switches provided with those dollies soon went out of order. Often this was put down to faulty fixing of the switches into the wall. One man, however, looking more closely into the matter, found that the fault was due to the dolly not being quite round, thereby not acting with the proper leverage when operated, and thereby subjecting the switch mechanism to unequal strain. This friend of ours now buys OUR BRASS SWITCH DOLLIES, cut from the solid rod on automatic machines. They are perfect in every respect, give better service, and look better. They are slightly, only slightly, more expensive. By using our Dollies, our friend's switches are improved in quality, and the greater turnover resulting increases his profits quite out of proportion to the very small extra initial cost. This example applies, of course, to many articles and parts, but we are often able to quote even lower prices, giving at the same time higher quality. We invite you to think it over, and consult us concerning any parts that you use, and to which the above example might apply. We specialise in highly accurate and intricate work, to any practicable limits. Let us quote for your requirements. | ||
