JESTER-SACKETT SOLID PARTITION 

THE JESTER-SACKETT SYSTEM of solid 
incombustible partitions provides a simple, 
economical and efficient base for plastering, which 
possesses many distinct advantages over the older 
systems of metal lath construction. 

The system requires no special tools, and can 
be erected speedily by any good mechanic. 

ECONOMICAL — Costs less than ordinary 
channel iron and metal lath construction because 
it uses only half as much channel iron; is more 
quickly erected; takes less plaster and the 
plaster is applied more quickly and in fewer coats. 

SPEEDILY ERECTED — Its simplicity en- 
ables the ordinary mechanic to erect partitions 
much more rapidly than metal lath partitions. 
Ordinary % ff Sharon or hot rolled channel iron is 
placed 24^4" on centers and solid sheets of 
SACKETT Plaster Board, 24" x 36", are locked in 
between them. The SACKETT Board is held 
securely to the channels by Jester steel clips. 
Both sides of this solid surface are plastered with 
Gypsum Plaster to the thickness required. 

When plastering metal lath partitions it is necessary to brace the partition to put on the first 
coat and wait for the scratch coat to dry before browning out. The JESTER-SACKETT System 
eliminates this delay. Only two coats are required on each side. You follow up with the finish 
coat on either side as soon as base coat has set. This simplifies construction and saves time. 

STRENGTH AND RIGIDITY — The rigidity of a metal lath and plaster partition is due 
almost entirely to the strength of the plaster and not to the metal lath over which the plaster is 
applied. JESTER-SACKETT Partitions, because of the strong, stiff plaster board core, have 
greater strength and rigidity than any metal lath and plaster partition of the same thickness. 

NO EXPANSION— NO CONTRACTION— As both Sackett and plaster are of Gypsum, the 
JESTER-SACKETT System forms a fire-resisting partition that will not expand, contract, warp, 
bulge nor buckle. 

FIRE RESISTANCE — Exhaustive tests prove that Gypsum is a most effective barrier to 
fire. Gypsum is incombustible and has low coefficient of conductivity. This partition, being built 
up almost entirely of Gypsum, provides fire resistance and protection equal to any form of 2 
solid metal lath and plaster partition. 

SOUND DEADENING— The SACKETT Plaster Board, composed of alternate layers 
of Gypsum and felt, covered on both sides with Gypsum Plaster, forms a partition superior 

in sound-proof qualities to any form 
of 2" solid metal lath and plaster partition. 

ADVANTAGES— The rapidity with 
which the JESTER-SACKETT partmon 
is erected, the sound-proof qualities, the 
speed in applying the plaster, the econ- 
omy of the finished wall — all big vital 
advantages — demand the serious consid- 
eration of all architects, owners and con- 
tractors. Its use means better partitions 
than the metal lath and plaster form of 
2" solid partitions at LESS COST. 

ATTACHING GROUNDS, TRIM, 

ETC. — Grounds are attached by wiring 
to the steel studs. Grounds coming on 
opposite sides of partition may be wired 
together. Wood door bucks, of same 
width as finished thickness of partition, 
are used. These details are similar to 
those used with metal lath.

METHOD OF FIGURING QUANTITIES REQUIRED 

In taking off quantities, figure six feet of channel iron to every square yard of wall area. 
Actual square feet of SACKETT Plaster Board required will run 5% less than the total area 
of the partition. 

JESTER-SACKETT clips come in four different shapes (see details below), all used in the 
construction. No. 1 is the metal yoke; No. 2, Spring Clip which works with the yoke; No. 3, used 
around all openings, also at intersections and joinings with other walls; No. 4, Corner Clip. 

To compute the number of Clips to be used in any job — add together the total number of 
lineal feet of all vertical corners and multiply by % 9 which will give the total number of No. 4 Clips. 

Add together the total number of lineal feet where partitions butt against the walls, corridors 
or door bucks and multiply by %, which will give the total number of No. 3 Clips. 

The grand total number of clips is 12 clips to the square yard. Subtract from this total number 
the sum of the No. 3 and No. 4 clips, and the remainder will be equally divided between No. 1 and 
No. 2 clips. 

The approximate proportion of clips required for the average job is 36 per cent of No. 1 ; 36 per 
cent of No. 2; 25 per cent of No. 3; and 3 per cent of No. 4. When not otherwise specified in order, 
clips will be sent in the above proportions, but the contractor should let us know the number of 
each clip he desires, if possible.

Sackett is the only plaster board composed of four sheets 
of felt alternating with three layers of gypsum. These 
alternate layers give the necessary flexibility; also prevent 
too rapid absorption during plastering. The felt has 
good tensile strength, does not contract, and the Sackett 
and plaster become one solid mass of gypsum. Note the 
felt-protected edges, another exclusive Sackett feature.

impregnation of felt by gypsum. The long, interwoven 
fibres afford the same ideal bond for the plaster as for the 
gypsum layer that is interposed during manufacture. One 
hundred and forty-five pounds straight pull was required 
to separate a 2 /„ " x 3 V panel.

Specifications for Jester-Sackett Solid Partitions. 

All partitions shown on plans, except as otherwise noted, are to be of JESTER-SACKETT construction, consisting of 
Sackett Plaster Board clipped to %" Sharon or hot rolled channel iron studs. The flanges of the studs shall not exceed 
". Channel studs shall be spaced 24? 4 " centers and fastened in a suitable manner to floors and ceilings. 

SACKETT Plaster Board ) , " thick, 24" x 36" in size, shall be placed between the channels and clipped to same with 
Jester clips, spaced 9" centers, starting 4>£" from floor or ceiling. 

CARPENTER CONTRACTORS are to attach, by wiring to the steel studs, M>" grounds for plastering, picture 
moulds, base boards and chair rails, where required, and are to set all bucks. Bucks shall be made from 2" x 2" pine, 
and properly braced and set. 

SPECIFICATIONS FOR PLASTERING 

SACKETT Plaster Board must nor he wet before applying plaster. (On solid partitions first apply brown coat on 
channel side of partition taking care to fill in behind grounds; then apply brown coat on other side to grounds or thickness 
to receive finish coat.) Plaster out to grounds, making all angles and corners flush and straight, ready to receive trim. 
Allow plaster on one side of partition to set before plastering other side. 

PLASTER— To be United States Gypsum Co.'s Gypsum Cement, Wood Fibre, or Prepared Plaster, mixed and 
applied according to manufacturer's directions. 

FINISH— To be United States Gypsum Co.'s Prepared Trowel Finish or Sand Float Finish, mixed and applied 
according to manufacturer's directions. (Note: If lime putty finish is specified, the best grade of hydrated lime should 

be used.)
