AIR-COMPRESSOR PUMP.
SPECIFICATION forming part Of Letters Patent NO. 501,090, dated July 11, 1893.
Application filed July 22, 1891. Serial No. 400,280. (No model.)
The objects of our improvement are first a' combination of parts causing the operation to be performed with less labor; second the uniting of the parts to make subsequent adj ustment more convenient; third the generalconstruction and combination of parts as hereinafter particularly specified.
Figure 1 is a longitudinal section of the pump. Fig. 2 is a top view and a section of the outlet valve.
Similar letters refer to similar parts in all views. 1
Upon the base A is mounted the cylinder B. Into the top of the cylinder B is screwed the cap 0. Upon the cap 0 is mounted the frame 0. To the frame 0 at the point 0' are pivoted arms 0 c which at their opposite ends 0 0 are pivoted to lovers 0 respectively. The levers c c extend from their connection with the arms 0 0 across the frame 0 and are united by a hand piece a. At a point 0 between the ends of the arms they are pivoted to the piston rod D.
The operation is as follows. The levers c 0 being moved up and down by the hand piece 0 force the piston rod D to move correspondingly. When in the position shown in Fig. 1 the hand piece 0 and piston dare partially raised and there is but little resistance by the air in the cylinder to downward pressure, so the simple lever movement with fulcrum at 0 0 is sufficient. As the levers approach the position shown by dotted lines the ends 0 0 are brought approximately into line with the pivots c c and the power of the joint formed by the arms a c and the levers c c is brought to' bear in forcing the piston 01 to the bottom of the cylinder when the compressed air offers the greatest resistance. By this arrangement of parts the additional leverage is applied at the time when the most resistance is to be overcome.
The cylinder B is immovably united to the base'A, preferably by soldering, to secure an air tight joint at thepoint of union b, and also to preserve the same relative position of the different parts, that no interference may be caused as sometimes occurs when they are united by a screw, in which case the valve chamber E may be brought into line with the hand piece 0 upon the, cylinder B being screwed to its seat in the base A. This causes an interference between these parts with incomplete action or injury. It is also desirable that the base and cylinder should always retain the same relative position, as the apparatus when placed for use is arranged in the position considered most convenient. The base A is formed of the parts a Q The part a is secured to the part a by screws of. The joint between the parts is made air tight by a packing (14. In the part a is an inlet valve a which may be of any approved form. In the part a. is an outlet valve 6 formed of a hexagon rod the edges of which keep the valve central as it moves up and down. The base of this valve is recessed and a packing e inserted. At e a stop is placed which limits the motion of the valve in an upward direction. This stop e prevents the seating of the valve against the upper part of the inclosing chamber. which would cut off the outlet of the compressed air'. Through the cap 0 are two openings 0 t0 the outside air to. permit the piston to act freely.
What we claim as our invention, and desire to secure by Letters Patent, is
In air compressor pumps, the combination with the cylinder, piston, and pump-frame, of links pivoted at their upper ends to the upper part of the pump-frame, and the operating lever pivoted to the lower ends of the links and to the piston rod, so that the links and the short arm of the lever form a togglejoint, substantially as specified.
, Signed at New York city, in the county of New York and State of New York, this 15th day of July, A. D. 1891.
