Description: end_display_feedback_code_window Change Gear Devices Oscar Perrigo "Showing the development of the screw cutting lathe and the methods of obtaining various pitches of threads." Perrigo considered 164 different patents pertaining to change gears issued from 1854 through 1903 when this was written. After throwing out all the impractical designs, Perrigo examines the remaining twenty-nine. You get a small, well-illustrated, fascinating book showing how the headstock of the engine lathe could be geared to the lead screw to get exactly the feed needed. It's not only about gearing, it's about the history of the lathe, the ingenuity that went into machine design in general. There are only three chapters as such: early lathe history, the patents, and the conclusion. But you'll see an old lathe with an oak bed, thread chasing techniques, pin gears and lantern pinions, and then gearing patents by Sellers, Humphreys, Bley, Miles, Riley, Wendel Norton, and many others. Fun reading for the machine nut (like you.) Great history. Interesting details about how these devices worked (some seem quite strange) and what their strengths and weaknesses were. A gem of a little book. I think you'll like it. Get one." - Lindsay. Softcover, 81 pp, well illustrated, 5 1/2" x 8 1/2".

ALL YOU NEED TO DO: If you, as a buyer, are not sure how to combine items yourself when placing an order (honestly, it’s not as easy to do as it could be), we will gladly do it for you. Simply order the items you want but do NOT pay for them immediately. We will combine them on the same invoice and send it to you with the correct postage or UPS shipping amount. TELL US BY E-MAIL IF YOU WANT TO USE STANDARD MAIL OR UPS: Standard Mail (aka Media Mail) is more economic but slower, taking sometimes up to 3 weeks, but usually only 2. UPS (domestic orders only) is faster but more expensive. For domestic orders, please tell us your shipping preference by e-mail right after you order (that is, whether you prefer delivery by standard mail or UPS). We recommend UPS for orders you want in 7 business days (sometimes less) and for orders worth more than $120.00. FOREIGN ORDERS: For foreign orders we use either Global Priority Envelopes for small books and DVDs, or Global Priority Boxes for larger books and mixed orders. We will measure and weigh your order to determine if we must ship in an envelope or box. For foreign orders it is not necessary for you to contact us about a shipping preference. Use the same procedure as above; order first and pay after you receive our invoice. Thanks!!
