Valve for Governors
|
Alfred Judson |
Rochester, NY |
Abstract:
he purposes of our invention are to reduce the variations in the speed of an engine when subjected to the variations of load to which it is liable, and to keep the rate of speed at all times within safe limits, without the necessity of employing the engineer, to open and close a stop valve, when machinery is thrown on and off; and, as subsidiary to these purposes, to diminish the friction and other resistances to which the old fashioned valve is subjected.
Claim:
Making the valve openings of governor valves to widen from the closed toward the fully open end and also in such a manner that when the governor acts upon the valve under low speed, it shall cause the opening or closing of that part of the steam passage where the rate of widening or narrowing of the passage, is more rapid than at the part on which the valve acts at high speeds. |

Device in machine for cutting round tenons
|
George Bailey |
Lockport, NY |
This machine was intended for making bedstead-rails, but it was also used for making garden implements such as hoes and rakes. An 1855 ad from Spalding's Machine Shop lists this machine: "Baily's Bed Rail Machine, for turning and tenoning square timber—eight hundred pieces in ten hours turned ready for the screw." An 1874 ad from T. R. Bailey & Vail shows a lathe with this patented feature. |

Method of feeding the bolt to the knife in shingle-machines
|
David Nicholson |
Lockport, NY |
An 1855 advertisement for Spalding's Machine Shop in Lockport lists, as one of their products, "Nicholson's Shingle Machine, for sawing Shingles, the best machine in use. It will cut 1000 shingles per hour for ten hours in succession. Price, complete, with jointer, $150." The ad predates this patent but in the absence of other information we assume that Spalding's also made this improved design. |
