SHAFTING AND PULLEYS.

Reading edition

Couplings and Adjustable Self-Oiling Hangers and Boxing.

This important branch is one of our specialties. Having had made in Massachusetts expressly to our order and for this particular purpose tools equal to any in the United States for speed and accuracy, we are prepared to furnish and keep ready to ship the supplies under this head.

The shafting, gear and pulleys properly proportioned are next in importance to the motive power.

1st. Shafting should run perfectly true and be turned to a gauge throughout its entire length.

2d. Couplings well fitted and easy to remove.

3d. Pulleys symmetrical in proportion and nicely balanced.

4th. The bearings should be self-oiling and adjustable, as by settling of the building or other causes their position changes.

With all of these items complied with, there will be less trouble and delays as well as a large per cent. of power saved.

In our price list we have fixed a price to each pulley, hanger, &c., for the convenience of our customers, and we here will say that in buying our work you do not pay for useless iron, while every part is strong and sufficiently heavy. Those wishing estimates by weight or wishing to purchase by weight, can always be accommodated.

Our Pulleys are turned, bored, correctly balanced and key-seated or set-screwed. For table of sizes see price list. All those over 36 inches diameter we are prepared to furnish with wood rims put up in a superior manner, of hard and soft dry timber, turned inside and out, well oiled, painted and balanced. The spiders are after the style shown in the cut under head of Elevators, &c., (represented as leaning against the Elevator.) The first segment or circle of the wood rim is of hard wood, and is carefully fitted to the iron spider and lug provided to receive the pressure and driving incident to the transmission of the power required. Clamp bolts let partly into the wood are provided to always keep the spider binding in the rim. No pulley rim is liable to get loose on the arms or spider when built by us.

Our Shafting is turned by a special machine made for the purpose, and no variation in size will be noticed. Pulleys, gear or bearings may be placed at any point with a perfect fit.

Our Adjustable Hangers avoid all liability of binding; the bearing or boxing-part is free to find its natural bearing; the ball and socket self-oiling pillow-block (Fig. 1, and Post Hanger Fig. 2. See engravings) have the same advantages. All have the improved self-oiling attachment making it necessary to oil but once in three months, and cleaning twice a year.

These bearings are adjustable every way as much as required, and not at all liable to heat.
