Application November 25, 1932,, Serial No. 644,387 2 My invention relates to an exerciser. An object of my invention is to provide a simple though sturdy frame-work and seat upon which a person exercises by going through the motions 5. similar to those required for rowing a boat.

Fig. 8 is a longitudinal cross section of a modified form of the device;

Fig. 9 is a plan View of a modified form of the roller;

Fig. 10 is a cross section on the line 10-10 of Fig. 9; and Fig. 11"is a cross section on the line 1010 of Fig. 9 with the belt removed.

I provide a rectangular shapeframe-work con-- sisting of the side pieces 2, and theend cross members 4 and 4' which are secured together by means of screws or nails, as shown in Fig. 1.

won the outside of each side piece 2, I provide a slot 6 which extends throughout approximately one-half ofthe length of the side piece.

The frame-work for a sliding seat is similarly constructed by side pieces 8, which are held together by a cross piece 10 at one end thereof, and by slats 12 at the other end thereof, which slats also form a seat. The sliding seat is constructeds'o that the side pieces 8 will extend over the side pieces 2 of the main frame, as shown in Fig. 1, so that the person seated upon the slats 12 would be unable to get his fingers caught between the slidingseat and the side pieces 2.

.The side members 8, in close proximity to the cross member 10, are provided with guide pins 14 which are adapted to engage in the slots 6 in the side members 2 of the frame. At the other end of the side members 8, in a position beneath the slats 12 forming the seat, I provide a roller 16 the ends of which are formed into trunnions 18. In the modified form shown in Fig. 7, I provide a stub shaft 18 which is driven into the ends of the roller 16. The other end of the stub shaft 18 is positioned within a ball bearing 55 20*wh'ich is imbedde'd'in the side member 8.

11 Claims. (Cl. 272-72) The roller 16-is made of wood or other material and is dividedinto twosections, the periphery of one of which is substantialy parallel to the axis of rotation, while theperiphery of the other section is conical in shape, as shown in Figs. 3, 4 and 5. The outside edges'of the roller 16 form cylindrical surfaces 22, which are adapted to engage the side members 2 of the main frame and roll thereon.

The division between the two sides of the roller 16 is defined by the partition 24, through which I pass a rope 26, one end of which-may be rolled about one side of the roller 16, while the other is rolled in the opposite direction on the other side of the partition 24; The end of the rope 26 which is rolled about the side 28 of the roller, extends therefrom to the cross member 4 and is secured thereto by passing the end of the rope 26 therethrough, and by tying a knot on the other side of the cross member 4, as shown in Fig. 2. The other end of the rope 26, which is woundabout the conical section 30 of the roller 16 extends through a pulley 32, which is secured to the cross member 10 and to'the handle 34 through which the endof. the rope 26 passes and is knotted on-the other side as shown in Figs. 1 and'2. 1

By pulling on the handle 34, the rope 26 will be unwound from its'position on the conical section3'0 of the roller 16, thereby causing the roller to revolve in a clockwise direction, asviewed in Fig. 2. U

As the roller 16 is turned in this clockwise direction, while the rope 26 is being unwound therefrom on the conical section 30 of the roller, the other end of the rope 26 will be wound upon the section28 of the roller '16 and thereby the sliding frame and seat will be caused to move in a directiontoward the cross member 4.

When the pulling force is released from the handle34, the seat frame-work will travel by force of gravity in the opposite direction and will resume the position shown in Figs.'1 and 2, at which time the rope 26 will have become unwound from the'section 28 of the roller and will again have been wound up on the conical section 30 thereof, as shown in Fig. 3.

By the use of the conical section 30, I am enabl'ed to utilize a simple means of gearing, so that when the pull on the handle 34 is first commenced from the position shown in Figs. 1 and 2, the ratio of the gearing will be approximately three to one, and thereby athree inch pull on the handle 34 and the rope 26 will only make theseat frame-work move one inch toward the too cross member 4 at the other end of the main frame-work.

As the rope 26 is uncoiled from the conical section of the roller 16, the ratio between the portions 28 and 30 is reduced until when the seat frame-work is nearing the cross member 4, the gearing ratio approaches a ratio of one to one.

The end of the main frame-work at which the cross member 4 is positioned is held in an elevated position by means of legs 36, which are pivotally secured to the side members 2, by bolts 37 and which are braced at their lower ends by a cross member 38. I provide a chain 40 which is secured to the cross member 4 and which may be fastened to the hook 42 in any desired link as shown in Fig. 1, thereby determining the distance between the cross member 4 and the cross member 38, so that the elevation of the side pieces 2, and cross member 4, may be readily adjusted.

The weight which is to be carried by the seat 12 is primarily placed upon the; roller 16 and the cylindrical surfaces 22 which directly transmit the weight to the side members 2 of the main frame. A portion of the weight will be transmitted to the side members 2 of the main frame through the cross member 10. The guide pin 14 is provided in the side members 8 to engage the slot 6 of the side members 2, so that there will be no possibility of the seat frame-work tipping up, if weight on the cross members 12 should become greater on the side of the roller 16 remote from the guide pin 14.

In the modified form which I have shown in Fig. 8, I have utilized substantially the same construction as that described above, in that I provide side members 2 and cross members 4 and 4', legs 36, and the cross member 38, to which is secured a hook 42 for engaging a chain 40 which is secured at its opposite ends to the cross member 4.

The seat construction is substantially the, same, but in this construction I provide a roller bearing 44 which is secured to the side members 8 by a screw or bolt 46, the end of this seat frame-work in proximity to the cross member 10 is substan-' tially identical to that disclosed in Figs. 1 and 2, in that the cross member 10 engages the edges of the side members 2 of the main frame and the uide pin 14 is provided to assure that the lower end of the frame-work will not to be improperl removed from the cross members 2.

In this modified form, I have provided an additional cross member 48, which extends between the two side members 2 approximately half way between the cross members 4 and 4'.

Secured to the cross member 10 of the seat frame-work, I provide a pulley 50, the construction of which is shown in detail in Figs. 9, 10 and 11.

In this construction, I utilize belts 52 and 54, the latter of which is secured to the cross member 48, by passing an end therethrough and securing it by a screw or nail 56.

The main casting 58 of the pulley is divided in the center thereof, by the flange 60 thereby providing two separate portions of the shaft for the straps 52 and 54. At the outer ends of the casting 58, I provide

washers

62 and 64 carried on a shaft 59 for guiding the belts 52 and 54.

These belts 52 and 54 are wound inopposite directions upon the casting 58, as shown in Figs. 9 and 10, and on opposite sides of the partition 60, and are secured thereto by means of acutaway or gouged out portion 61 of the casting 58 being provided for the extreme end of the straps or belts 52 and 54, which straps or belts are provided with a transverse groove 66, through which the pin 68 is passed. The pin 68 passes through the groove 66 in the belt 54, the hole 69 in the partition 69, and the groove 66, in the strap 52.

When the seat frame-work is in the position, as shown in Fig. 8, the belt 52 will be in a wound condition, as shown in Figs. 9 and 10, so that when a pull is exerted upon the handle 34, and the strap 52, the pulley casting 58 will be caused to revolve in a clockwise direction (as viewed in Fig. 10) on the shaft 59 extending therethrough, thereby unwinding the strap 52 and winding the strap 54 which will cause the pulley 50 to approach the cross member 48 and move the seat in a direction toward the cross member 4.

I have provided another slight modification in the side members 2, which is disclosed by the waving portion 70 thereof, over which the roller bearing 44 must pass either in an upward or downward travel.

This waving portion 70 of the side members 2 provides a slight variation which may result either in a smooth up and down motion or in a vibrating motion depending upon the length of the bumps or waves 70, and the diameter of the roller bearing 44. The waves 70 are provided in approximately the center between the two extremes to which the roller bearing 44 will pass on the side members 2, since I have found that by placing waves on the side members 2 at either extreme positions that it becomes difficult to start the seat frame-work in either its upward or downward motion.

By this construction, I have been able to provide an exerciser which is sturdy and inexpensive to make and has very few parts which become easily worn out. p

The exercise afforded by my exerciser issubstantially the same as that provided by rowing machines, but in my construction I do not utilize any spring elements which are likely to break and cause injury to the party exercising upon the machine.

I have found that my device is particularly suitable for use by children because they are Willing to exercise upon my device, since the device not only affords exercise but amusement.

It will be obvious that I may find it necessary to make minor changes from time tojtime without departing from the spirit of my invention.
