Opinion

SAGE, District Judge.

Defendants move to strike from the files the entire deposition of witness E. M. Bentley, called and examined as an expert by the complainant on the prima facie case, or to compel him to answer 33 questions put by counsel for tbe defendants on cross-examination, and which he declined to answer under advice of counsel for the complainant. All these questions were objected to as immaterial, irrelevant, and hypothetical. Counsel for complainant insist that the issue in the case involved in this matter is whether defendants’ construction, as proved by Mr. Bulkley, a witness for complaint, is an embodiment of the claim in suit. The suit is upon patent No. 495,443, for traveling contact for electric railways, applied for by Charles J. Van Depoele, and assigned to complainant.

The witness Bentley, in his direct testimony, defines the invention in controversy as follows:

“The device itself is characterized by a long swinging arm, extending obliquely upward from the car to the conductor. * ® * The long swinging arm carried at its outer end a contact device, which is made to bear on the underside of the conductor, while its inner end of the same arm is joined to the car, on both a transverse and vertical axis, so that the contact device on its outer end may he swung laterally through a wide arc. and may also be depressed vertically through a considerable distance. This arrangement allows the contact device to ® * * follow readily in its variations, vertically and laterally, the line of the conductor. * ® ®”

In cross-examination he was asked:

“What would you suggest as the proper average height of the conductor wire above the cars?
“A. At presen!, in street-ear work, the conductor is some six or eight feet above the roof.
“29 xq. And what is the length of the extreme play on a vertical line of a trolley wheel, and which you would advise as the best to meet the ordinary requirements?
“A. In some roads the height of the trolley wire varies from fourteen to twenty-four feet, and the trolley wheel, to have a capacity for meeting the extreme condition, should have a vertical play of ten feet.”

He was then asked to state the length of defendants’ device,— which was used in the tunnel of a coal mine, — as shown upon their exhibit (“Sketch Vintondale Locomotive”), and answered that the arm was only three feet long, and that on that locomotive, if it was three feet and a half between the axles as shown hv said sketch, the trolley poles were about three feet long. Further examined as to the structure of defendants’ plant, he answered as follows:

“Then, assuming that the coal is of a thickness above the average, we will say six feet, for anything now within our knowledge, it may be true, may it not, that the trolley wheel on that Vintondale locomotive never vibrates more than six inches relative to the top plane of the locomotive, may it not?
“A. Of course, if the trolley wire is so arranged with reference to the track that It never varies more than six inches from its level with relation thereto, the arm would not vibrate more than six inches.”

Counsel for the defense then sought to interrogate Mm with respect to the application of the patent, and of the invention to defendants’ mechanism, as follows:

“31 xq. Let us then assume from now on that a commercially successful car constructed on the plan of this illustrated in the patent in suit would require [616]*616a trolley equipment which would permit the trolley wheel to vibrate' through a distance of ten feet.
“Please take the drawing which I now hand you, which delineates precisely the same parts and arrangement that is shown in the drawings in this Yan Depoele patent in suit, except that the trolley wheel is limited to a vibration of six inches, and I ask whether a construction in accordance with this drawing would contain the subject-matter of claims 2, 4, 8, 12, and 16.
“(Counsel for complainant objects to the question as immaterial and hypothetical, and is not an issue raised by any of the pleadings in this ease, and instructs the witness that he need not consider any drawings or structure which is not properly proven in this case.)
“A. In view of the instruction of counsel, I decline to consider your drawing.
“32 xq. You have already in the record in this case stated under oath as follows:
“‘A long arm mounted on top of the car carrying a grooved wheel'at its outer end, and continually pressed upward against the undersurface of the wire, and having capacity of swinging through several feet on a vertical pivot, and of also swinging through a number of feet upon a horizontal hinge or pivot," was the thing which made overhead systems of electric railroads a success for general use.’
“Disliking to indulge in hypothetical questions' which cannot be exactly and accurately delineated, I have made this drawing for the purpose of getting a clear definition of your understanding of the invention in controversy, and of the scope of the claims which you have referred to in your direct examination. My question, coupled with this drawing, I believe to be as accurate and specific as it is possible to put it in order to ascertain your meaning when using on this record, as you have, such terms as ‘a long arm,’ and an arm ‘swinging through a number of feet on a horizontal hinge or pivot.’ I am desirous, on behalf of the defendants, of ascertaining to what extent these matters enter into the invention in controversy.
“And, with this explanation, I repeat the question, and ask whether, first, this drawing is sufficiently intelligible for you to understand the question.
“(Complainant’s counsel requests defendants’ counsel to state the number of the question and answer of the witness from which he purports to have made a quotation.
“(Counsel for defendants replies that, if the last note of complainant’s counsel is intended to challenge proof of identity as to this witness being the same party who filed two or three different affidavits with the preliminary injunction papers, he replies that he is astonished at any such effort, and supposed that would be waived. In direct reply to the last inquiry, he states that the above quotation was made from the affidavit of one E. M. Bentley, filed in this record, with the papers accompanying the motion for preliminary injunction. To assure himself, he temporarily withdraws the last question, and presents the following:)
“33 xq. Are you the same E. M. Bentley who filed three affidavits in this cause, and which were used at the hearing of the motion for preliminary injunction?
“A. I made, I believe, three affidavits for use in this cause on the motion for preliminary injunction, and I presume they were filed and used.
“34 xq. Please turn to page 176 of the printed record of complainant, prepared for the presentation of the motion for preliminary injunction, and ascertain whether the quotation I have above made from the second affidavit is correct, and whether you made that statement.
