Abstract
Abstract A tile laying cart comprising a simple base frame composed of a pair of elongated channel members connected in transversely spaced relationship and the opposite ends thereof comprising the forward and rearward ends of said cart, a chest and chin-supporting pad member which is narrower at the forward end than at the rearward end is mounted for vertical adjustment relative to and above the forward portion of said base frame member and the upper surface of said base frame member comprising a supporting means for a stack of tiles to dispose the same conveniently for access to the occupant of the cart. The rearward portion of the base frame member also supports a transverse knee-supporting pad member so that when a worker is disposed in kneeling position upon the knee-supporting pad member and chest-supporting pad member, the worker may propel the cart by operation of his toes while leaving both hands and arms free for manipulation incident to laying tiles.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
250 words
A tile laying cart comprising in combination, a pair of elongated members, means extending between and fixed to said members to fix the same in spaced parallel relationship to form a base frame, pairs of caster-type supporting rollers mounted upon said frame adjacent the opposite ends thereof respectively comprising forward and rearward ends in use and said supporting rollers being mounted in transversely spaced relationship to each other to prevent tilting of said frame in use, similar vertical members fixed at one end to said elongated members intermediately of the ends thereof but closer to the rearward ends than the forward ends, a normally horizontal chest-supporting pad member having a narrower projection at the forward end thereof when in use positioned to support the chin of the occupant of the cart, a supporting frame member having a horizontal portion attached to the lower surface of said chest supporting pad member and also having a pair of projections depending from the rearward end of said supporting frame and engaging said vertical members for support thereby and vertically adjustable therewith to dispose said chest-supporting pad member above and parallel to the forward end portion of said frame at desired elevations, and a knee-supporting pad member extending across and fixed to the rearward end portions of said elongated members, the upper surfaces of the forward portions of said elongated members comprising tile supporting means adapted to receive a stack thereof between said members and said chest-supporting pad member and said supporting frame therefor.
Claim 2
Dependent Claim
250 words
A tile laying cart comprising in combination, a pair of elongated members, means extending between and fixed to said members to fix the same in spaced parallel relationship to form a base frame, pairs of caster-type supporting rollers mounted upon said frame adjacent the opposite ends thereof respectively comprising forward and rearward ends in use and said supporting rollers being mounted in transversely spaced relationship to each other to prevent tilting of said frame in use, similar vertical members fixed at one end to said elongated members intermediately of the ends thereof but closer to the rearward ends than the forward ends, a normally horizontal chest-supporting pad member having a narrower projection at the forward end thereof when in use positioned to support the chin of the occupant of the cart, a supporting frame member having a horizontal portion attached to the lower surface of said chest supporting pad member and also having a pair of projections depending from the rearward end of said supporting frame and engaging said vertical members for support thereby and vertically adjustable therewith to dispose said chest-supporting pad member above and parallel to the forward end portion of said frame at desired elevations, and a knee-supporting pad member extending across and fixed to the rearward end portions of said elongated members, the upper surfaces of the forward portions of said elongated members comprising tile supporting means adapted to receive a stack thereof between said members and said chest-supporting pad member and said supporting frame therefor.
Claim 3
Dependent Claim
68 words
The tile laying cart according to claim 1 in which the opposite ends of said knee-supporting pad member extends beyond the outer sides of said elongated members a predetermined distance and the rearward pair of caster-type supporting rollers being attached to the lower surfaces of said projecting end portions of said knee-supporting pad member and one of said pairs of caster-type supporting rollers being of the swivel type.
Claim 4
Dependent Claim
35 words
The tile laying cart according to claim 2 in which the pair of caster-type supporting rollers which are attached to the opposite projecting ends of said knee-supporting pad members are the swivel type supporting rollers.
Claim 5
Dependent Claim
55 words
The tile laying cart according to claim 1 in which said elongated members are channels having the open faces thereof disposed downwardly and the forward end portions of said channels receiving and supporting the rollers comprising the forward pair thereof, said rollers being supported upon axle members extending between the side walls of said channels.
Claim 6
Dependent Claim
81 words
The tile laying cart according to claim 1 in which said vertical members are tubular and said elongated members further including reinforcing plates secured therein adjacent the connecting flange portion of said channels, said connecting flanges having an aperature of suitable diameter to receive the lower ends of said vertical members and said lower ends being welded to said reinforcing plates in said channels to effect a rigid union of the lower ends of said vertical members relative to said channels.
Claim 7
Dependent Claim
81 words
The tile laying cart according to claim 1 in which said supporting frame for said chest-supporting pad member is formed from tubular stock and the forward end of said supporting frame is generally yoke-shaped and extending rearwardly, said depending projections of said tubular supporting frame being bent substantially perpendicularly from said yoke-shaped portion and extending downwardly therefrom, said similar vertical members being tubular and telescopically receiving said downwardly extending end portions of said supporting frame for said chest supporting pad member.
Claim 8
Dependent Claim
62 words
The tile laying cart according to cliam 6 in which the outermost tubular member of said telescopically related tubular members are provided with set screws threaded relative to the walls thereof and operable to engage the inner tubular member to secure said supporting frame for said chest-supporting pad member at a desired vertical position above said elongated members of said base frame.
Claim 9
Dependent Claim
62 words
The tile laying cart according to cliam 6 in which the outermost tubular member of said telescopically related tubular members are provided with set screws threaded relative to the walls thereof and operable to engage the inner tubular member to secure said supporting frame for said chest-supporting pad member at a desired vertical position above said elongated members of said base frame.
Claim 10
Dependent Claim
94 words
The tile laying cart according to claim 1 in which the upper surfaces of said elongated members forwardly of said similar vertical members attached thereto comprise the connecting flanges for the side members of said channels, said connecting flanges being disposed uppermost and thereby providing smooth surfaces within a common horizontal plane and are free of obstruction to receive a supply of tile directly below said chest-supporting pad member and at a location readily accessible to the occupant of the cart when disposed thereon and supported by said chest-supporting pad member and knee-supporting member.
