Harry N. Marvin, Direct Examination. 32G3 A. I here produce the illustrative mechanism, and its present condition illustrates some of the features embodied in the cameras of the period concerning which I have testified, and it is arranged so as to be capable of modification so as to show the different types of mechanism that I have referred to, reference being made at the same time to photographs which I have had made, showing the mechanism as arranged in several ways, illustrating features concerning which I have testified. Mr. Church : Counsel for the defendant offers the illustrative apparatus produced by the witness, in evidence, and requests that the same be marked "Defendants' Exhibit 178." The exhibit is received in evidence, and is so marked. By Mr. Church: Q. If you have prepared a description of this illustrative apparatus in its various adjustments, I wish you would read it to the Examiner as a short mode of putting upon the record a description of the apparatus. A. I have prepared a brief description of this mechanism in its different aspects, which I will read as I arrange the mechanism, to illustrate the various features concerning wThich I have testified. This mechanism as now arranged, and which arrangement is shown by Photograph No. 1, which I here produce, illustrates the common features of cameras in use at the beginning of 1908, as described in the first part of my answer to the question concerning such cameras. In this mechanism and photograph will be noted, the single stationary lens, marked "A" on the photograph; the single flexible sensitized tape-like film, marked "B" on the photograph; the supports on opposite sides of the lens, marked "C" and "Cl? on the photograph; the intermediate section crossing the lens, marked "Dv on the photograph ; the main driving shaft, marked "E" on the photograph ; the intermittent feeding mechanism connected with the driving shaft, which I here detach from the rest of the mechanism and exhibit, but which is obscured on the photograph by the flywheel "F." (The witness here detaches the portion of the mechanism referred to.)
