Hipolito Screen and Sash Co. Is Now a Great and Growin$ Concern

One 'of the older com'panies identified with the building material industry of Los Angeles, fhat has made tremend' ous progress i:n the past few years is the Hipolito Screen and Sash Company, of which Mr.L. M. Rosenbe'rg is President and in charge of factory operations, and Mr. H L. Rosenberg, his brother, is Secretary-Treasurer and in charge of sales.

Organized in 1897, the company has moved its factory twice, each time seeking larger quarters. I,n 1913 they moved to their present locatibn at the block bounded by 21st, Alameda and 22nd Streets, adjacent to the Ha;mmond Lumber Company.

operated at such a degree of efficiency that in cutting its rough m,aterial there is scarcely enough wa'ste lumber for crating purposes.

The operation of the factory itself is not only highly standardized but efficiently laid out. The rough lumber enters the building from the air drying sheds at one end and moves forward progressively until it reaches the porver sander, which is capable of sanding 4 to 6 screens at once, and is finally taken into the stock room' to await shipment'

In addition to the large fa'ctory devoting its time entirely to stock size wind,ows, screens and screen doors, what would in itself be a very comfortable business forr any or-

At an earlier period in their l-ristory, rruch time was devoted to the manufacture of the now famous Hipolito Reversible Windows, but as this business was largely confined to offices, hotels and apartments, they then began to make u'indows an.d window screens.

A few years a,go the Rosenberg brothers conceived the idea of m,anufacturing a stock size winclow scree;n after the same manner that sto,ck size sash have been made for years. The idea was well received by the building trade, it being but a short time until the factory was devoting practically all of its attention to stock size screens, the special sizes becoming the smaller portion of their business.

"It was proof conclusive," said Mr. Rosenberg, "That'our assumption was correct, and that ovet 9O/o of the window o,penings in the ordinary 'dwelling can be screened with stock size screens."

As the business developed more and more, highly specialized machinery was installed until today the factory is 20 ganizatiotl to handle alone. is conducted by the "special size departrrertt," where a group of men and machines ke'ep busy making special designs arrd special size window screens to meet architects reqttirements..

It is a far cry fronr that day when the making of stock size screens occupied but one day a week, and the special sizes required the full 'capacity oi the {actory as it stood then, to today when with greatly increased facilities the mill pro,per w,orks continuously on the production of standard stock sizes, and almost a small mill in itself is engagetl in the manufacture of the special designs and sizes.

A particularly significa,nt thing about the development oI this business and one that should interest everyone in the lumber industry, is the stea-dy intensive advertising which has characterized this firm's efforts for new business.

Prior to the entry of the California Lumber \'Ierchant into the local territory, there was no advertising medium that could be considered as reachin,g stricly the building in-
