Yesterday, I explained all about my internship project identifying and cataloguing apparatuses. Today I want to enlist your help in identifying eleven items that remain unidentified in the new database. Historians, loyal CHP fans, summon your inner detective and help solve the mysteries of these ten items that have defeated me!
You will win unending CHP glory: that is to say, if you make a successful identification and there’s an interesting back story then I’ll publish it in future blog posts. Wild speculation is also encouraged for its entertainment value! Comment away!
1. Rolling dowel mounted on wood stand, one large, one small. Accompanied by clear plastic sheet and electric plug. Appears homemade.
2. Two wooden apparatuses. Largest apparatus has movable knobs on either end and a set of telegraph like keys in the center. Second wooden device is square and numbered in a square, increasing from one on the outside corner to 100 on near the center. Has pins and adjustable metal pegs that have the remnants of thin wire.
3. Sheet of wood with adjustable screen (similar to the kind used for mirror drawing), instrument showing temperature, made by H. D. Trarice Co., what appears to be metal shelf holders, a welded sheet of metal, and a plastic cover with a clear plastic window and a hinged opening.
4. Box shaped apparatus with open sides and an electrical plug. Made by Lafayette Instrument Company.
5. Long metal instrument with rotating part and half circle angle markings and measurement markings on the back of the long piece. Made by E. Zimmerman, Leipzig, Model #86070.
6. Grey electrical switch and power supply.
10. An electrical apparatus mounted on a wooden stand. Made by Spindler & Mover.
P. S. I promised I’d finish the story about the mystery carpeted box. Turns out it’s a soundproof box used with duckling hearing experiments, donated by Gilbert and Nora Gottlieb.
How did I find out? Well, on the shelf next to the mystery box there was a mostly empty wooden crate that had clearly been used to ship something to the archive. The return label listed the Gottliebs and in the bottom of the crate was a 1994 article ‘Influence of Auditory Experience on the Development of Brain Stem Auditory-Evoked Potential in Mallard Duck Embryos and Hatchlings’, published in Behavioral and Neural Biology by Lubov P. Dmitrea and Gilbert Gottlieb. There was only one apparatus donated by the Gottliebs listed in the old database: a timer used for duck imprinting experiments. I decided, based on this, that the box must have been used to ship the timer, but that the timer had been misplaced in the move.
But when Cathy Faye took a look, she suggested that the two items on the shelf might be connected, the crate used to ship the mystery box instead. Of course! A closer look at the article in the crate confirmed the box’s identity—“a sound attenuated box” in which “Acoustical stimuli” (tone pips at 500 and 750 Hz) were played through a loudspeaker 10-12 cm above the ducklings’ heads. Volia! Mystery solved! An interesting story reattached to an otherwise mystifying carpeted box!
