OTTO SCI-IAERER, OF STUTTGART, GERMANY.
CARRIAGE-GUIDE FOR LA'II-IES.
To all whom "it may concern:
Be it known that I, OTTO SCI-IAERER, mechanical engineer, citizen of the Republic of Switzerland, residing at Stuttgart, in the Kingdom of Wl'irtemberg, Germany, have invented certain new and useful Improvements in Carriage-Guides for Lathes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
The present invention comprises a novel form of covered carriage guide for ordinary turret lathes, in which the carriage tracks are arran ed under lateral guard flanges that in effect constitute aprons carried by the bed cheeks and on their outer sides in the form of inverted prisms. The arrangement of the carriage tracks is characterized, among other features, by placing the same at unequal heights with reference to the cheeks in order to prevent the displacement of the carriage, and between the front carriage and the adjacent guard flange, the lead screw and rack for the longitudinal motion of the carriage are placed, which latter part may be arranged either beneath or above the carriage tracks. By disposing the carriage tracks in the manner described, a twisting of the entire carriage would have to take place before it could rise simultaneously on the end points situated opposite to one another.
In the accompanying drawings formin a part of this specification, and in which like characters of reference indicate corresponding parts, Figure 1 is an end view partly in section of one form of the invention. Fig. 2 is a front elevation, partly in section. Fig. 8 is a view in plan. Fig. 4 is a view similar to Fig. 1 of a modified form of the invention.
The bed cheeks a are provided at their upper portions with lateral extensions or guard flanges a that carry guides b for the spindle and slide puppet. Underneath the flanges and on the exterior of the cheeks a are arranged carriage tracks 0 having prismatic guide ways that are engaged by similar shaped guides 9 carried by the carriage and surrounding the flanges a. For the lubrication of the guides 9 there are provided oil chambers d, in the usual manner, in which are placed lubricating wheels 6. As will be noted by reference to Figs. 1 and l, the bed Specification of Letters Patent.
Application filed September 21, 1905.

Serial No. 279,422.
cheeks a, flanges a and tracks 6 and 0 are all formed integral, thereby presenting a much more rigid structure than if these parts were made separately and detached, and insuring .greater accuracy in the operation of the lathe with a measurable decrease in the cost of its production.
The carriage tracks 0 are placed at unequal heights, whereby the displacement or one sided lifting of the carriage caused by the pressure of the tool against the work, is avoided, for the reason that in this arrangement the turning of the entire carriage must take place if it is to rise simultaneously on both its opposite terminal points. Thus a tendency to lift or tilt the carriage at one end will be met by the inherent resistance in the material of the carriage to the twisting action thus called into play. This arrangement thus permits a simplification of the construction of the guides and an elimination of particular securing devices for holding the carriage in the guides. The track 0 placed upon the front side of the apparatus, is, according to the construction shown in Fig. 1, formed on its under side with a toothed rack z, and effects by means of the engagement of the toothed wheel is gearing with it, the longitudinal movement of the carriage. Upon the same side of the lathe there is placed directly over the track 0 between the flanges a and the track 0 the lead screw it, whereby the side pressure of the carriage upon the guides is considerably diminished. In the second form of the invention shown in Fig. 4, not only is the lead screw it placed between the flanges a and one of the tracks 0, but also the toothed rack 2', whereby the traction elements are brought as near as possible to the lathe points, and the unfavorable influence of the pressure of the tool upon the work is restricted as much as possible.
By the arrangement of the parts moving the carriage and regulating this motion below the flanges, these latter are protected against injury by falling shavings, lubricating material, tool and so forth.
Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is
1. In a lathe, the combination, with bed cheeks having laterally extending guard flanges, and provided with tracks at unequal heights beneath said flanges, of a carriage arranged to travel on the lathe bed, and proand a carriage-propelling member mounted above the lower track and beneath the guard flange at a distance above the horizontal 15 plane of the higher track substantially equal to the difference in elevation of the two tracks.
In testimony whereof I hereunto affix my signature in the presence of two witnesses. OTTO SCHAERER. lVitnesses:
ADoLF LEHBERT, ERNST EURENMAN.
