'EXERQISING APPARATUS FOR OARSMEN.

Specification of Letters Patent.

Patented April 28, 1908.

Application filed July 25, 1907. Serial No. 385,595.

To all whom it may concern.-

' the city of Halifax, in the county of Halifax and Province of Nova Scotia, Canada, machinist, have invented certain new and useful Improvements in Exercising Apparatus for Oarsmen; and I hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to an exercising ap paratus for the use and training ofoarsmen, by which those muscles brought into action in rowing, can be developed, strengthened and trained to the same extent, and under the same conditions as if the training were performed on the water. In actual rowing the blade of the oar is moved'toward the bow of the boat, and then immersed in the water and propelled. toward the stern, bringing into play the muscles of the fingers, wrists, arms,

ody, legs and feet, until the propelling stroke of the blade is completed, when the blade is lifted from the water and moved towards the bow for the next propelling stroke, the power required to propel the boat varying according to the condition of the water, and the direction and force of the wind.

The object of the present invention is to construct the exercising apparatus so that all the movements made in actual rowing can be attained by the use of the apparatus under substantially the same conditions of load as results from the resistance offered to the boat by the water, and by the direction and force of the wind. v

To carry out this object the exercising apparatus is provided with a rockable boat shell or part thereof fitted with stationary or sliding seats and outrigged oarlocks similar to those of an ordinary racin shell, with handle portions of oars mountet? in the outrigged rowlocks, and connected by links to an operable mechanism.

For a full understanding of the invention reference is to be had to the following description and to the accompanying drawings,

in which;

Figure 1 is a plan, and Fig. 2 is a side elevation of the exercising apparatus. Fig. 3 is a detail of one of the winding drums.

Like characters of reference refer to like parts throughout the specification and drawmgs.

The boat shell 1, is rovided with seats 2, which may be either xed or sliding. Outrigged oarlocks 3, project from the side of the shell slightly to the front of the seats and in the oarlocks 3 are mounted the oar handles 4, provided with the usual collars 5, to engage the oarlocks and determine the length of oar handles on the inboard side of the oarlocks. Each oar handle is provided, on the outboard side of the oarlock 3, with a collar 6, having a ring 7. Standards 9 are provided at the rear and on opposite sides of the boat shell 1, and pivoted to the side faces of the standards 9 are bell crank levers 10 having their diverging

arms

10 and 10 extending u wardly, one bell crank lever being provide for each oar handle. The apparatus shown in the drawings is constructed for four oar handles and four bell crank levers 10 are provided, but the number of oar handles and bell crank levers can of course be varied as required. To the arm 10 of each bell crank lever 10 is pivotally connected one end of a link 8 the other end of which is connected to the ring 7, of its respective oar handle. Pivoted to the standards 9, above the bell crank levers 10 are rocking levers 11. One end of each rocking lever 11 is connected to the arm 10 of its respective bell crank lever by a link 12. To the rear of the standards 9 are bearing standards 13 in which is mounted a shaft 14.

Loosely mounted on the shaft 14 are ratchet disks 18 having ratchet teeth 19 projecting from their side faces. Oscillatingly mounted on the shaft 14, adjacent to the ratchet disks 18, are actuating levers 20 having a limited lateral movement e ual to the depth of the ratchet teeth 19, so t iat the levers can clear the ratchet teeth when assuming their initial position. Connected to the shaft 14, are spring holders 23 having pressure springs 24 engaging the levers 20 and normally holding them in contact with the side faces of the ratchet disks. The levers 20, are provided with weights 21, and are connected by links 22 with their respective rocking levers 11. Loosely mounted on the sh aft 14, adjacent to the ratchet disks 18, are drums 15, having clutch members 15 engaging with corresponding clutch members on the ratchet disks 18 so that they will revolve unitedly in one direction with, and in the opposite direction independently of, the ratchet disks. Forming part of the drums 15 are ratchet wheels 17 and interposed between each adj acent pair of drums 15 is a spacing sleeve 16 to prevent the lateral movement of the drums ards 9, are arms 50, and pivoted to the arms 50 are detent pawls 29, engaging the ratchet wheels 17, which permit of the rotation of the drums 15, in one direction and arrest the rotation in the opposite direction. Passing over pulleys 26 secured to the ceiling 60 are ropes 25. The ropes 25 are connected at their ends to their respective drums 15 and are arranged to be wound thereon, and are connected at their opposite ends to weights 27.

During the movement of the outboard end of each ear handle towards the bow of the boat, the link 8, lowers the arm 10 of its respective bell crank lever 10 permitting the arm 10 to rise and actuate the rocking lever 11 to lower and position the actuating lever 20 to engage the ratchet teeth 19 positioned to be engaged by it. The movement of the outboard end of the oar handle towards the stern of the boat lifts the arm 10 of the bell crank lever 10 and lowers the arm 1O causing the bell crank lever, through the agency of the link 12, to rock the rocking lever 14 and lift the actuating lever 20. The lifting move ment of the actuating lever 20 revolves the ratchet disk 18 a distance proportionate to the stroke of the oar, and the revolution of the ratchet disk 18 causes the winding drum 15 to wind a corresponding length of the rope or cord 25, thus lifting the weight 27 a corresponding distance. The weight 27 can be interchanged when desired, to vary the load on the oar handle to correspond with the estimated resistance of the water and the force and direction of the wind. The unwinding movement of the drums 15 and cord 25 is prevented by the engagement of the detent pawls 29 with the ratchet wheels 17. Each movement of the oar handles winds a corresponding amount of the cord 25 on the drum 15, and if the movement of the car handle is actuated for a suflicient time, the weight 27 will be finally raised to the ceiling. It will then be necessary to release the detent pawl 29 from the ratchet wheel 17 so that the detent pawl can revolve in the reverse direction and permit the cord to unwind. The drums 15 may be locked in pairs or series to the shaft 14 by the pins 22 and caused to revolve therewith, and the advantage of this is that when the drums and ratchet disks are revolving freely on the shaft 14 each oar is revolving its respective ratchet disk and drum and lifting its respective weight. When the drums 15 are locked to the shaft 14, the shaft will be caused to revolve with the drums locked to it, and all such drums will be operated by the one .movement of the oar or cars.

The boat shell 1, is provided with transverse slots 30, through which project bolts 31 fitted with nuts and washers 31*, by which the boat is roekably held. The purpose of this construction is to compel the oarsmen using the exercising apparatus to maintain their proper balance in the boat shell, i. e. the same balance they will be required to maintain on the water.
