These clocks do not fit into the main part of the 33 collection of tower or skeleton clocks or time locks. However, they still, with the 34 exception of the first two, share the general theme of being able to see the movement 35 works. The first photo is a Telechron Type A from the mid 1930's. Second a rare Telechron 36 Type C, the only complete working example known, and was used in systems that operated in a DC voltage 37 environment. The next photo shows a side-by-side comparison of the Type A and Type C 38 (pendulum not shown on C). The third clock is a Telechron Type E from 39 the early 1930's meant to run in a partial vacuum. Very rare, and only 40 one of five examples known, again this being the only operational one. 41 Fourth a Collin Wagner, 1886, France. A beautiful example of the 42 horological art. Jeweled movement with Wagner's rocking frame 43 remontoire. One of two examples known. Fourth a Hahl pneumatic, 1913 with spring remontoire and extra 44 electrical bell actuating complication. This clock used air pressure rather than 45 electricity to control the slaves. This mechanism is Rube Goldberg device to see in 46 operation. <p>The Telechron Type A helped bring about the standardization of electrical 47 frequency control throughout the United States allowing for clocks of all types to be 48 controlled by small, cheap synchronous motors which lead to the demise of pneumatic 49 systems like the Hahl in the United States.</p> 50 <font color="#008000" face="book antiqua, times new roman, times"><em><big><strong><p>Click 51 on the picture to go to a page for more detail.</strong></big></em></font></p> 52 <p align="left"> <a href="warren_master_clock.htm"><img src="Telechron_A.jpg" alt="Telechron A.jpg (147486 bytes)" WIDTH="232" HEIGHT="600"></a> <a href="telechron_type_c_detail.htm">
