Referring now in detail to the various views of the drawings, in FIG. 1 an exercising apparatus of the rack type made in accordance with the present invention is illustrated and designated generally at 10. The apparatus comprises a rectangular shaped wooden base board 12 for supporting a pair of bottom radial extending arms 14, 14 bolted to the metal plates 16 fastened to the base by bolts 18 and nuts 20. A pair of uprights 22 formed of channel iron with flared elongated edges 24 is yieldingly supported on the ends of the arms 14 by means of bolts 26 and wing nuts 28 spaced from the uprights by coil springs 27 to permit upright 22 to be resiliently selfadjusting.

At each end of the base board 12 on the plates 16, there is a pair of closely spaced tubular metal upright poles 3t), 30 soldered at their bottom ends to the metal plates 16. The poles are formed with a plurality of pairs of opposed holes 32 extending therethrough. A pair of opposed holes at the bottom end of the poles 30 receive bolts 34 and wing nuts 36 fastening the arms 14 to the poles. Adjacent the top of the poles 30, 30 there are bolts 38 extending thereacross fastening the poles to each other by means of wing nuts 40. Below the bolts 38, there are flanged plate-like metal brackets 41 secured to the pairs of poles 30, 30 by means of bolts 42 extending through holes in the flanges thereof and Wing nuts 44 on the protruding ends of the bolts.

Another pair of upper radially extending arms 46, 46 with one end seated on the brackets 41 and pivotally connected by a bolt 46 and wing nut 46" to the upright poles 30, 30, and the other end extending into the channel shaped uprights 22 at the top thereof where it is yieldingly secured to the uprights by means of bolts 48 and coil springs 49 and wing nuts '50. A pair of closely spaced metal books 47, 47 are secured to the under surface of the arms 46, 46 in line with the hooks 68, 68 of the bar 54. The free tops of the pairs of poles 30, 30 may be provided with rubber caps 52. The bracket 41 has a top plate 41' that overhangs the same and upon which the top arm 46 rests in a cantilever manner while being bolted to pipes so that no force is imparted to the channel uprights 22. A horizontal round lift bar 54 extends through the pairs of poles 30, 36 and is provided at its ends with pivotally mounted U-shaped metal brackets 56-, 56, carrying wheels 58, 58 of hard rubber, adapted be formed. with, a knurled outer surface 60' and with rubber sleeves 62 serving as a cushion where it passes through the poles 30, 30. At its ends, the bar 54 is formed with opposed pairs of spaced holes to receive threaded bolts 66 passing through the bar and formed with hooks 68 atone end and secured in position by wing nuts 78 at the other end. A similar pair of hooked bolts 72 is secured in each pair of bottom arms 14 in line with the bolts 66, 66 and pairs of compressed springs 74, 74 are attached at their ends on the opposed hooks 68, 68 and 72, 72 as shown in FIG. 1.

, High and low pairs of inverted U-shaped sliding lift bar supportingbrackets 80 are placed at two specific locations on poles 30, 30. Thesebrackets 80 support the horizontal lift bar 54 at these two locations to permit the-user to easily free himself from under the bar. Each bracket 80 comprises a straight round metal bar 82 and an L-shaped metal bar 84. The round bar 82 is formed with a hole 86 at one end thereof and extend loosely and slidably through opposed pairs of holes 32, 32. The other bar 84 had one end 88 extending through the hole in bar 82. The two long bars 8-2 and 84 define an inverted U-shaped bracket or frame. The bar 84 is formed with a plurality of actuating pins 90 projecting radially therefrom, remote from the end 88. The bar 84 projects along the outside of the poles 30, 38 and is slidably supported on one of the poles 30 by a bracket 92 constituted by a metal plate 94 formed with an integral curved finger 95 looped around said pole 30 and secured thereto by a bolt 96. The plate 94 is formed with a head 98 having a transverse slot 100. A washer 2 is mounted on the end of the bar 82 to serve as a bearing for a spring 104 carried around the bar between the washer and the body of the adjacent pole 30 so that the U-shaped bracket or frame moves against the action of the spring 1104. In moving each sliding bar lock supporting bracket 80, back and forth, the object is to move the round bar 82 activating the actuating pins 90 of bar 84.

An L-Shaped round pin 33 is slidably and removably mounted in opposed pairs of holes 32, 32 in each pair of poles 30, 30 for supporting the horizontal lift bar 54 at any desired height along the poles 30, 30.

A portable bench 110 is provided for use with the exercising apparatus. This bench comprises an elongated rectangular shaped wooden body 112 provided with wooden legs 114 and 116 at the ends of the body. A wooden block 118 is juxtaposed against the leg 114 and its sole purpose is to prevent any movement of platform 12 when bench 110 is being used with the exercising apparatus. The leg 114 extends below the bottom of the block 118. The platform 12 is formed with a cutaway portion 122 and extending across the cutaway portion 122, there is a round wooden bar 126 secured at its ends to the adjacent edge of the base 12 thereby closing the cutaway portion. The round wooden bar 126 can be used as a handle to carry the platform '12 when the apparatus has been disassembled. A strap 128 extends springs 74' until it reaches its optimum. This movement can be repeated any number of times by the user. At the across the bottom surface of the body of the platform at each end thereof and is fastened by fastening elements 130. The scrap serves as a stirrup.

In using the exercising apparatus for a prone press, for example, the bench 110 is placed across the platform 12 and the extending leg 114 inserted into the cutaway porpushes it from the chestand from a position resting on 7 looking pins 33-, 33 upwardly against the action of the completion of this movement, it then becomes necessary for the user to place the lift bar 54 at such a position on the pairs of poles 30, 30 away from his chest and high enough so that he can arise from bench 110. This becomes possible by resting bar 54 on locking pins 33, 33 and unhooking all springs 74 from hooks 68. The bar 54, with no springs attached, is then pushed upwardly to the position where the small fingers of each hand are adjacent to'the actuating pins 90, of the sliding bar lock supporting bracket '80. The small fingers then flip the bracket inwardly by pushing actuating pins forcing 'bars 84 and 82 of bracket or frame 80 to move simultaneously so that the bar 82 hereof is below the bar 54 and movable through the opposed holes .32 of the poles 30 and the bar 84 slides in the head 98 of the plate 94 across the outside of the poles so that pressure on the bar may be released with' the bar 82 supporting the lift bar 54 in its optimum position along the poles.

For close arm tricep press, similar use is made of the apparatus but the hands are pla'ced close together on the bar 54.

For sit up exercises, the lift bar 54 is moved down along the poles 30, 30 to a position close to the bottom of the apparatus and the user sits on the end of the bench with his legs over the bar 54, his knees encircling the bar with his feet in the stirrup 128 on the bench 110.

For military press, the user sits on the end of the bench 110 or on platform 12 without bench 110 and spreads his arms apart and pushes upon the lift bar 54 against the action of the springs 74. This exercise necessitates the use of adapter 64 shown in FIGS. 8 and 12 where the attachment location for springs 74 changes from hooks 72 at arms 14 to hooks 69 on the adapter.

For pull down exercises as shown in FIG. 13, the

springs 74 are moved from between the bar 54 and bottom arms 14 to the hooks 47 on the top arms 46 and the hooks 68 on the lift bar 54. With the bar to his back, the user sits on the bench 110 or kneels on the platform 12 and with outstretched arms pulls down on the bar 54. For chinning exercises, the springs are removed from the apparatus and the horizontal bar 54 moves to a point adjacent the top of the rack where it is held against movement of the sliding bar lock supporting brackets 80. With the bar positioned to the back of his head, the user grasps the bar with his hands Wide apart and with his heels on the floor intermittingly raises and lowers himself. Instead of resting his heels on the floor the user may place his heels on a chair and follow the same routine. The user may also chin himself by raising his legs ofl? the support and while bending the legs lift and lower himself.

The exercising apparatus is very versatile and other forms of exercising may be peformed as upright rowing, dead lift, squats, bent over rowing, curls and shoulder shrugs.

The versatility of the apparatus is also enhanced by the use of an adapter 64 shown in FIGS. 8 and 12. The adapter 64 takes the place of the bottom arms 14, 14. A pair of adapters can be mounted on the poles 30, 30 at any desired height above the platform 12. The adapter 64 comprises a short rod length formed with pairs of closely spaced parallel holes to receive metal hooks 69, 69. The outer surface of the rod is threaded at 64' for receiving an internally-screw threaded perforated metal disc 63. In use, the rod 64 is inserted through the space between pin 33 and the adjacent pair of poles 30, 30 and secured between by shaped threads 64' extending from one side of the poles 30, 30. The disc 63 is then turned on the threads until it engages the outer surfaces of the poles whereby the adapter is clamped in position on the poles 30. The tension springs 74 are then hooked onto the hooks 68 on the horizontal bar 54 and onto the hooks 69 on the adapter 64. This arrangement of the springs facilitates various exercises, such as curls, shoulder shrugs, upright rowing and side bends.
