This invention relates to locomotive seats. At the present time, as far as American rail roads are concerned, the requirement is that 10 comotive seats be securely‘ fastened to the ?oor of the locomotive cab at all times. Locomotive seats as now used and constructed are made of wood and are fastened to the ?oor of the cab in one position, without thought to the con venience of the engineer. ‘ An object of the present invention is to pro vide a locomotive. seat that maybe adjusted to different positions and to different heights to suit the convenience of the individual engineer op erating the locomotive, and which seat, at the same time, may be securely fastened to the ?oor of the cab to meet. present railroad require ments. - I The invention, together with its objects and advantages will be‘ best understood from a study 20 of the following description, taken in connection in elevated position relative to the section I 0, lugs I2 are engaged in the shorter notches I3. To support the section I I in lowered and tele scoped position relative to the section Ill, lugs I2 are engaged in the longer notches I4, as is ob vious » The section II of the- seat supports the up holstered seat I5proper, and the same is hinged adjacent one edge thereof to one side of the sec tion II through the medium of hinges I6 ar- ’ ranged within the con?nes of the section II and wholly concealed when the seat I5 is at rest on the upper edges of the section II. Except for the side thereof in which the seat} I5 is hinged,‘the remaining sides of the section" 16 II at the upper edges thereof are bent outward wardly to provide narrow ?anges I'I upon which the seat I5, proper, rests when in the position shown in Figure 3. Further, in accordance with the present in 20 with the accompanying drawings, wherein: Figure l is a top plan view of the seat with vention, the floor plate 5 has rising therefrom I and adjacent one corner thereof an integral stud the upper section of the seat removed. Figure 2 is a perspective view of the upper section of the seat. Figure 3 is a vertical sectional view taken sub stantially on the line 3-3 of Figure 2, but with the upper section of the seat in an elevated po bolt I8. To accommodate the bolt I8, the bot~ tom 9 of the seat section II] is provided with a slot arrangement shown in Figure 2 and which 25 consists of a-pair of right angularly related in terconnected slots I9, 20, and a diagonal slot 2I that joins the slots I9, 20, at the angle between the slots I9, 20, as clearly shown in Figure 2. To secure the seat at the desired position of 30 adjustment relative to the floor plate 5, there is threadedly engaged with the stud bolt I8, 9. hand nut 22 adapted to be threaded home against sition. Figure 4 is a perspective view of a ?oor plate. In accordance with the ‘present invention there is provided a “dead” or stationary floor plate 5 provided with openings 6 to accommo date screws or other fastening elements ‘I, 35 through the medium of which the plate 5 is se cured to the floor 8 of the locomotive cab. Resting on the floor plate 5 is the bottom 9 of the lower box-like section I0 of the seat. This section ID in addition to the bottom 9 has 40 side and end walls rising vertically from the "bottom 9, and the section III is preferably formed wholly of metal. Further, the seat comprises an upper section II which is of substantially rectangular frame like form, constructed from sheet metal, and adapted to be lowered and telescoped into the lower section II] of the seat. _ To support the section II in either raised or lowered position with respect to the section I 0, 50 the latter is provided ‘on opposed walls thereof with internal lugs I2 while the seat section II in each‘of twoopposite sides thereof is provided with short notches I3, and in each of two‘other opposed sides thereof with longer notches I4. As shown in Figure 3, to support the section II a washer 23 disposed on the stud bolt I8 be tween the bottom 9 of the seat section I 0 and 35 the nut 22. . Obviously, provision of the intercommunicat ing slots I9 to 2| inclusive permits of a wide range of adjustment for the seat, permitting the latter to be moved laterally toward or away from 40 the side of the locomotive cab or either back ward or forward to suit the convenience of the engineer. Manifestly, to' adjust the seat to the position desired, the lever nut 22 is loosened and the seat 45 is then slid in the desired direction, being guided to the position desired by means of the cooperat ing bolt I8 and slot section in the bottom plate of the seat structure. When the desired posi tion is effected, the seat is securely fastened to 50 the cab by tightening the lever nut 22. The height of the seat may be readily raised or lowered simply by lifting out the section II, giving it a quarter turn, and then placing it in the section III of the seat. 2,122,345 It will thus be seen that I have provided a loco 2. In a locomotive cab seat, and in combina motive cap seat which may, and is, in the pre tion, a stationary floor plate having a bolt rising ferred embodiment thereof, made of steel, and‘ vertically therefrom, a lower supporting section which is adjustable to any desired position to suit having a bottom and vertical wallsv rising from the convenience of the engineer operating the locomotive. Also, a seat embodying the features of the present invention will meet the require ments of the railroad, provision being made, as above noted, to securely fasten the seat to the 10 ?oor of the cab, as is necessary to meet the pres ent railroad requirements. It is thought that a clear understanding of the construction, utility, and advantages of a seat of this character will be had without a more de 15 ‘ ' tion and provided on each of two sides thereof ' 1. In a locomotive cab seat, and in combina tion, a stationary ?oor plate having a bolt rising 20 vertically therefrom, a lower supporting section having ‘a bottom and‘ vertical walls rising from said bottom, said bottom being provided with a plurality of angularly related intercommunicat ing slots to accommodate said bolt'and to permit a shifting of the seat supporting section in sub stantially any and all directions relative to said ?oor plate, said seat supporting section having pairs of lugs on the inner side of two opposed walls thereof, a second seat supporting section telescoping within the ?rst seat supporting sec -,tion' and provided on each of two sides thereof >with elongated slots to engage said lugs, for sup porting the second section in telescoped position ,135 ing slots to accommodate said bolt and to permit a shifting of the seat supporting section in sub stantially any and all directions relative to said ?oor plate, said seat supporting section having 10 pairs of lugs on the inner side of two opposed walls thereof, a second seat supporting section telescoping within the ?rst seat supporting sec with elongated slots to engage said lugs, for sup 15 Having thus described the invention, what is . porting the second section in telescoped position tailed description. claimed as new is: .25 said bottom, said bottom being provided with a 5 plurality of angularly related intercommunicat Within the ?rst section, said second seat section having relatively shorter slots in each of‘ two other opposedsides thereof for accommodating said lugs for supporting the second section in a ; raised position relative to the ?rst section. ' within the ?rst section, said second seat section having relatively shorter slots in each of two other opposed sides thereof for accommodating said lugs'for supporting the second section in a 20 raised position relative to the ?rst sectiomand a seat member hinged adjacent one edge ‘thereof to one side of the second seat supporting section and resting on the top of said second section, 3. In a seat of the character described, a pair 25 of telescoping hollow seat-supporting sections, the outer one of said sections having opposed sides provided with lugs on the inner faces there of, and the inner one of said sections having two opposed sides thereof provided with elongated 30 slots to engage said lugs for supporting said inner section at one position of adjustment relative 'to the outer section, and said inner section also having in two other opposed sides thereof rela tively short slots for engagement with said lugs 35 to support said inner section at a second posi tion of adjustment relative to said outer section.
