Abstract
Abstract The invention relates to a manually operated man-portable sprayer comprising a reciprocating pump the body of which extends through the upper wall of the reservoir, through which it can be caused to slide by a side-mounted actuating lever, said pump being disposed centrally in relation to the reservoir. Force is transmitted from the actuating lever to the pump body by a stirrup-shaped two-branch connecting-rod having its top hingedly connected to the pump body and coextensive therewith, and its two branches partially engaging into undercut reinforcing grooves formed in the reservoir wall on either side of and adjacent to the location of the pump body.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
126 words
In a manually operated man-portable sprayer having a piston-type reciprocating pump the body of which extends through the upper wall of the reservoir, through which wall said body can be caused to slide by a side-mounted actuating lever, the pump being disposed centrally in relation to the reservoir, the improvement consisting in that force is transmitted from the actuating lever to the pump body through a stirrup-shaped two-branch connecting-rod which is hingedly connected to the top of the pump body and coextensive therewith and the two protected branches of which are operative within two reinforcement-forming grooves provided in that wall of the reservoir which is remote from the wall to be applied against the carrier's back, on either side of the location of the pump body.
Claim 2
Dependent Claim
126 words
In a manually operated man-portable sprayer having a piston-type reciprocating pump the body of which extends through the upper wall of the reservoir, through which wall said body can be caused to slide by a side-mounted actuating lever, the pump being disposed centrally in relation to the reservoir, the improvement consisting in that force is transmitted from the actuating lever to the pump body through a stirrup-shaped two-branch connecting-rod which is hingedly connected to the top of the pump body and coextensive therewith and the two protected branches of which are operative within two reinforcement-forming grooves provided in that wall of the reservoir which is remote from the wall to be applied against the carrier's back, on either side of the location of the pump body.
Claim 3
Dependent Claim
51 words
A sprayer as claimed in claim 1, in which the actuating lever is supported in a reversible bearing-forming block fitted to the reservoir via an intermediate reinforcing box-like structure having a base engaging into the reservoir and lateral flanges engaging into said grooves, the pump piston being attached to said base.
Claim 4
Dependent Claim
26 words
A sprayer as claimed in claim 1, in which the reservoir is bounded by cylindrical or conical lateral surfaces for facilitating its manufacture by injection moulding.
Claim 5
Dependent Claim
41 words
A sprayer as claimed in claim 3, in which the filling orifice may be closed by a cover attached to the reservoir by a strip, said strip being attached to a pipe forming an air inlet valve and a drain pipe.
Claim 6
Dependent Claim
25 words
A sprayer as claimed in claim 1, in which integrally injection-moulded openings or recesses are formed therein for fitting such accessories as shoulder-straps and clips.
