To all whom it may concern:
Be it known that l, STEPHEN G. WILsON, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, ful Mechanical Chair, is a specification.
The purpose of my invention is to combine theparts of a Morris chair in such a manner as to cooperate with exercising mechanisms.
A further pur ose of my invention is-to use the back an body of a Morris chair to form tracks upon which a sliding seat may operate. y
A further urpose of my invention is to make use of t e front piece of a Morris chair for an extensible foot rest.
A further urpose of my invention is to use the side frames supporting the arms of the chair as supports for rowing machine handles.
A further purpose of my invention is to make use of the arms of my chair to secure of. which the following retarded rotary movement for the handles of extended arm position 1n dotted lines.
a rowing machine.
A further purpose of my invention is to combine the parts of the exercising machines so that they shall fit to or be a part of the chair construction.
It further consists of other novel features of construction, all as will be hereinafter fully set forth.
Figure 1're resents in perspective, a Morris chair capa le of being arrangedfor use as an exercising machine. Fig. 2- represents a similar construction in vertical section, the
arts being in a slightly different position.
ig. 3 represents my device in perspective arranged as a rowing machine. Fig. 4 represents a similar construction to Fig. 3 in longitudinal section, additional parts being shown. Fig. 5 represents the arm of my rowing machine in fragmentary longitudinal section. Fig. 6 represents'the position of the side frame and arm in plan view showing lighe 1g. 7 represents in pers ective and Fig. 8 in section, portions of t e arm and supporting Fig. 9 represents a section of Fig. 5 upon line w-a;. Fig. 10 represents in section a portion of the arm and back showing the manner of their attachment. Fig. 11 represents an enlarged detail section of a portion of Fig. 2.

have invented a new and use Referring to the drawings. 1 designates a frame of a Morris chair having a cushion seat 2, side members 3 and back 4. The back is hinged to any suitable pivot bar 5 preferably by strips 5. The segment 6 offers means of attachment of a catch 7 upon the back in any one of a number of openings 8. The normal arm 9 is supplemented by a special arm 9 which'is pivoted by a universal joint at 10 so as to move vertically and horizontally and to be free to turn so as to secure attachment at any suitable point 11 on the sides of the back when the arms are .turned into a vertical position.
The back is formed in two parts, the outer part proper shown by reference 4 and an inner frame 12. These are both pivoted about the same bar so that they can be lowered together, as for rowing machine use, as
seen in Figs. 3 and 4, or the inner part 12 can be lowered separately for such use as running exercise, as seen in Fig. 2. Any suitable latch or catch keeps them together when desired.- When the two parts are lowered together any support 13 is used. The back is then substantially horizontal so that guides 14 upon the back form a line with guide 15 within the body of the chair when the cushion is removed permitting travel of the rollers 16 of a sliding 1 The chair back is preferably provided with seat 17 thereon.
a removable cushion 18. Beneath this cushion are located rollers 19 which are retarded in their rotation by a brake 20. The brake 20 is formed in the preferred construction by means of a cord which is secured at one end as, at 21' and turned a half turn about each of the adjoining rollers passin in this manner about the entire set of rol ers successively, then entirely around the roller and back upon the opposite sides of each of the rollers to the initial roller which is secured by any suitable adjustable device comprising a drum 22 to which the end or ends of the rope are attached so that winding of the thumb piece 22 tightens the brake and ratchet and latch 23 retains the drum in position. Thus the tension on the cord or rope and consequently the brakin eflect upon the rollers may be varied at wil In the position shown in Fig. 2, the rollers 19 constitute a tread mill or running exerciser and the back 4 remains in raised position to steady or affor supplort to the one exercising.
T e sides 3. of the arm portion of the chair carry arms 9 and are hinged to the back as are also arms 9 but the sides 3 andthe arms 9 are pivoted at different points so that as they open to the position shown in Figs. 3 and 4 there is relative movement between arms 9 and 9, the path of movement being against rotation in either ustable hand brake direction. by an ad- 50 whose tension adusted by means of a wheel 51 having a shaft passed through the part 52.
