| Munn & Co., patent attorneys
My invention relates to improvements in that class of machines for cutting key-seats in the center holes of pulleys and gear-wheels, in which a vertical saw is used for working through the eye of the wheel while lying on the table; and the first part consists in connecting the saw to cross-head by an oscillating block journaled thereto. Second, it consists, also, in attaching saw to block by screws passing through trunnions of block into sockets of saw.
Having thus described my invention, I claim as new and desire to secure by Letters Patent:
1. The connection of the saw to the crosshead by the oscillating block journaled thereto, substantially as specified.2. The attachment of the saw to block by the screws, screwing through the trunnions of said block and into sockets in the saw, substantially as specified. |
