In 1888, a partnership of Christian H. Baush and John M. Munn were in business as Munn & Baush in Holyoke. The following year, four sons and a daughter joined the business and the name changed to C. H. Baush & Sons. In 1896, the senior Baush died and the business name changed to Baush & Harris Machine Tool Co., which relocated to Springfield. In 1900 the name changed again, to Baush Machine Tool Co.

In 1965 the company relocated to Milwaukee. They survived into the early 1970s before quietly disappearing.

  C.H. Baush & Sons.

  Prominent among the machine manufacturing interests of the city of Holyoke is the firm of C. H. Baush & Sons, who have just completed, at a cost of $10,000, an addition to their works, making now in use about 24,000 square feet floor space and available for the development of their business. The building shows the above engraving. The firm consists of C. H. Baush, four sons and a daughter, a combination which ought to win success as it deserves to.

  The business was organized in 1888, and the firm made all kinds of castings, but their specialty is machine tools.

  The Post Radial Drill, shown herewith, is one of the most successful of their inventions and is made in various sizes, from 2,500 to 24,000 pounds.

  BAUSH & HARRIS MACHINE TOOL COMPANY SPRINGFIELD.

  In July the managers of the Baush & Harris Machine Tool Company were informed by the agent of the union of which their moulders were members that certain patterns which had been sent from Providence were obnoxious to them because of a controversy between the Providence firm and the moulders' union. In response to the complaint of the employees the Baush & Harris Machine Tool Company decided to stop their works in all departments. Accordingly the workmen were paid off on July 10, and were told that work would be suspended for an indefinite period.

  On the following day agents of the union had an interview with the managers of the company, which it was agreed should be continued on the next day following. At this time the company expressed their readiness to meet the wishes of the workmen by excluding the objectionable work, but were surprised that the union presented as an additional demand that the works should be run on the union plan, meaning that no man should be employed unless he could show a union card as evidence of good union standing. This was a new question, which the company would not then consider, and negotiations came to an end. The works were reopened, some of the moulders returned to work, but most of them found work elsewhere. The ban of the union was placed upon the establishment, accompanied by all the annoyance of a strike, although the beginning of hostilities was a lockout.

  On July 18 the Board of its own motion went to Springfield and visited first the moulders' headquarters, with a view to arranging for a conference between the parties. It was learned there that the strikers were scattered in various directions, and that the conduct of the controversy, so far as the workmen were concerned, had been transferred from the local organization to the national executive board of the union. Apparently this shifting of responsibility simply increased the difficulty of doing anything to bring the parties together, because there was no member of the national executive board in Springfield, and no one who could be found in that immediate vicinity was prepared to assume the slightest authority or responsibility, even to try to effect a settlement in co-operation with the State Board.

  The next morning, however, the Board called upon the managers of the company and had an interview, in which they gave the history of the controversy and their willingness to do anything in reason to settle it. They still asserted their readiness to reinstate the former moulders and helpers, without discrimination; they had sent away the objectionable work, but were resolved not to bind themselves to the union card.

  In the absence of any who would undertake to act for the moulders, the Board was unable to exert any practical influence upon the controversy; although, had the circumstances been different in this respect, there seemed no good reason why a settlement could not have been effected promptly, which would recognize the evidently fair intentions of the company, and at the same time cause the moulders to return to work under favorable conditions. At the latest accounts which reached the Board the relative positions as to the questions in issue remained the same, but work was going on apparently much as usual.

  George Henry Baush died at Northfield, Mass., September 12 with an abscess on the lungs, aged forty years. Mr. Baush, born in Holyoke, Mass., was the son of C. H.
